Unable To Connect With Wireless Router
I have not been able to connect to my server via browser, ftp or email since my server had a OS reload & security package installed.
If I disconnect and remove my wireless router I can access the server directly from the modem. When the Linksys WRT54G is connected I can go anywhere on the net with no problems, except my server.
Is there something they might have done at the server to block wireless router access?
I get a timed out message when I ping any of the IP's on the server with the wireless router connected.
Linksys has been of no help and I have talked with Clearwire who owns my modem.

Laptop + Wireless Router = LAN
I hate to ask this, because I bet it's been asked many times before, but I want to start a little class teaching web development at a local night school and I wanted to set up a LAN using my laptop, CentOS, and a wireless router. The idea is to have the students develop their pages and download files and get used to the idea of what a server is. I see about ten students sitting in a room, popping open their laptops, logging onto the network, and then pointing their browsers to a certain IP address which would be the home page for the class. If this is possible, can anybody point me in the right direction to teach myself how to do it?

UK Users Unable To Connect To One Of My Websites
I've been getting a lot of complaints today on my forum that users cannot view their websites which are subdomains on a seperate domain that I own. It makes no sense why they would have access to the forums which is on the same dedicated server, using the same IP, and with the same nameservers as the site they cannot access. This issue started last night out of nowhere. Where should I even start looking? It appears to only be with overseas users since none of the US and Canadian users have any issues with either domains or their subdomains.

Warning: Fsockopen(): Unable To Connect To 127.0.0.1:25
Yesterday I had to install a renewed SSL Certificate. Managed to get it installed, in Plesk under domains/www_mydomain_com, but I also deleted the default SSL from the server/certificates area... So then I was getting an dns 500 error when browsingour site and I could not start httpd from within plesk. Went in through SSH and tried to start it from there and got and error stating it could not find the SSLCA cert it was looking for. So I edited my httpd.include file to point to my new certificate. Now http works, but my email has stopped? What gives how could the two be related! I can log into my webmail, compose message and when I send I get: Warning: fsockopen(): php_hostconnect: connect failed in /usr/share/psa-horde/pear/Net/Socket.php on line 108 Warning: fsockopen(): unable to connect to 127.0.0.1:25 in /usr/share/psa-horde/pear/Net/Socket.php on line 108 I have started and stopped psa, qmail. Rebooted the server. I tried the telnet localhost 25 but I get connection refused. Anytime I check qmail status it says stopped. Don't know if that is right or not. I know I am not recieving emails asI have sent many today through other accounts and they all come back undeliverable. We do run an online store as well so I am kinda nervous when our email goes down! Time to hire a server admin? I am running Plesk 7.5.4 on Red Hat 9 on a Virtual Dedicated Server with GoDaddy.

Unable To Connect Via SSH With Centos5 X64
I have been struggling with a couple of new servers that we want to run Centos 5 on. For a second assume that is our desire so going back to 4.x isn't an option yet. Now while I mention Centos 5, the problem seems to be with PAM and x64. When trying to login to the server via ssh, the login succeds but then immediately kicks the user out. I have tried this with root and another user created. I have set the UsePam option to no to try to resolve this in sshd_config. On the H-Sphere forum I found this reference: [url] " if i try to connect with ssh and i enter the right password i get an error and ssh closes the connection. The answer already was in the ticket you opened: Quote: That is known bug dealt with PAM authentication. The bug was fixed for i386 systems long time ago. But it was not fixed for x86_64 architecture. We build FreeVPS kernel new version 1.5-13.1 for x86_64 architecture to fix the problem. We also installed the kernel into the box IP 64.71.227.16. Please reboot the box with the new FreeVPS kernel version: 2.6.9-freevps-1.5-13.1smp. Let us know the result." Does anyone know how to resolve this? A reinstall of PAM was attempted by a well known sysadmin here but to no avail.

Wireless Authentication Gateway
I'm doing a project for my school ( a small technical college) and we're trying to come up with some sort of wireless authentication gateway. This doesn't need to be locked down and super secure, this is a state run school with an open wifi network. Basically we want all wireless users to be forced to view a splash page/AUP and agree to it before being able to access the web. couple issues: -Super low budget, so enterprise solutions are pretty much out of the question -must be as transparent as possible to the use: no MAC registering with the IT dept. no added software, no RADIUS certs etc. -we have limited access to the actual router and all administration but be done by the upstream provider(including inter-vlan routing) I've looked at NoCAT and really like it but because of the existing network topology its going to be hard to force all traffic through a central box for filtering/auth What I'm wondering is if there is a way to do selective DNS poisoning to redirect all lookups to a web authentication server(similar to nocat's system). After a host is authenticated their DNS would resolve correctly. I know someone could just go out by IP or potentially use different DNS servers but we really aren't that concerned about it, all they have to do is click 'accept' anyway.

Stop Outbound Spam On An Open Wireless Network
I'm not sure if this is the right place to be posting this, but at our hotel, we have wireless routers (Linksys) that any of our clients can use to connect their laptops to the internet. We have been getting reports from our ISP that spam has been coming from our external IP address, so I wanted to know what people would recommend as ways to combat either our computers or any of our clients' computers from sending out spam. The internet is connected through a firewall/server computer running linux. I thought about blocking port 25, but I'm sure we would have clients complaining about not being able to send any mail.

Router
I am having a big question which has been often asked, but which all the time depends on the network topology; so first let's be honnest : - I have no experience with BGP / OSPF - I have no experience with routers (except SOHO models - I will not have to make this to work in a productive environment So in the next month we will get an AS number and few IP addresses; the goal is to test drive a gigabit network before using it as productive network; I would like to ask some advices here for early all aspecsts, let's show some important points : - Which brand? - Which model? - Maybe refurbished? The key points for me: I am looking for a cheap chasis but extensible with time when it will be needed - Extensible system - Very cheap for small use (at beginning maximum $ 2-3k) - Trafic rate : ~ 100 MBit/s to 4-5 GBit/s - Type of trafic : HTML / JPG / GIF / PNG / CSS / EXE / ZIP (shared hosting network)

Router
getting my own AS number, but this seems to require also a router. I don’t really have a strong knowledge of routing, just basic knowledge. As I think I understood, I have two possibilities for routing, to buy a ready-made router (Cisco, Juniper, Nortel,…) or to simply setup a simple box with Linux or BSD OS, some NIC and use a software such as Zebra, Quagga, etc… So my question is : - Is it possible to use for professional purposes a BSD box with Zebra ? - What is entry price for a good Cisco router (approximately) ? - Does BASIC routing setup requires a very strong knowledge ? In case this would became concrete soon, people answering could maybe get some paid work doing this for us.

Router VS Switch
We have a small hosting company (currently 24 racks) that we are expanding to hold 100 racks. We have several 3640 series routers behind a 7200 series router (our edge router) that feed into numerous 2950 switches and 515 & 525 pix firewalls then into the racks with customer supplied switches within the rack. I want to replace all the 3640 and 2950 switches with a 6500 series switch. The only routing we do within the 3640's is subnet routing to the switches which make up individual networks for each customer. My goal is to use the 6500 switch to limit bandwidth for each port feeding a customer and to eliminate all but the 7200 router and the 2950 switches. Does anyone know of a reason or reasons this would not work or if it's just a bad idea. Looking for pro's and con's,

Router And A Firewall
I am about to design my company network. The network will be designed like : we have 3 providers of IP transit, one will be the main network while the two other will feed the first network and manage a highly available network, probably using protocols like BGP4 and OSPF. The current size of each fiber is 45 Mbit/s per operator. So I am looking for : A router : - able to handle each provider with up to 200 MBit/s in/output - able to support protocol such as BGP4 or OSPF - able to output snmp for monitoring - have a little intuitive GUI for basic operations and have a real routing OS (like IOS or JunOS) - is branded and warrantly (a plus would be hardware extensible) - not too big box, something between 1 and 6U A firewall : - able to handle ALL the traffic to all carrier - able to work as a SPF (drop all, allow only what I want, very accurate rules) - have a little intuitive GUI for basic operations - not too big box, something between 1 and 6U About brand, most probably about Cisco, Juniper, Extreme or some good brand. Which model would you advice me as router and which as firewall ? The price is not the main proccupation until it will do job just fine, but I would prefer to don't buy too expensive also.

Which Cisco Router To Use
I am currently looking at these Cisco switches: - Cisco 2924 WS-C2924-XL-EN Enterprise Switch - Cisco 2950 WS-C2950-24 Catalyst Switch - Cisco 3512 WS-C3512-XL-EN Enterprise Switch - Cisco 3524 WS-C3524-XL-EN Enterprise Switch - Cisco 3548 WS-C3548-XL-EN Enterprise Switch 1) I was recommended to chose the XL-EN model switches because it seems they have more Memory, but the second one in the list (Catalyst) is not a XL-EN, is that going to have any affect performance wise? or it doesn't really matter? 2) I was also recommended to choose managed switches because that way I can use the SNMP features to measure bandwidth, are any of the switches above unmanaged? 3) I also want to be able to manage the switch remotely, web managed, are any of the switches above web-manageable? 4) Most importantly, when my datacenter give me a 100mbit drop, I dont know which port to plug it in in the 29** series. In the 35** I see it clearly but I am not able to see it in the 29**, any ideas? 5) On some of these switches I see a special port called "Console", what is it? where does that connect to? 6) Do any of the switches above not have a console port?

Which Router Model
I have decided to finally remove all my servers rented from provider to provider to one single place. I want to manage everything, so basically route the traffic (at this time without BGP or OSPF), my current average of traffic for all servers together would be about 15 Mbit/s with top at 35-45 Mbit/s. I want to buy a cheap router (no computer router), I'd like to buy a chassis with very extensible and upgradable router, so I can start with a basic card and later use BGP (and maybe OSPF) and have ability to push from 30 Mbit/s (to over 1000 Mbit/s by upgrading cards and memory). So, which (refurbished or not) chassis can I buy ? Which card would you setup with it ? The important is really the ability to start with low cost configuration and go up to very high rates without having to change all (of course once I will be average over...).

A Multiple WAN Router
I am looking for a good router which will handle two separate WAN connections and bridge them together. Basically, we have DSL at our office (1.5mbps down / 769kbps up), its the only service we can get, cable is not offered, and a T1 inst fast enough and costs too much. We require a faster connection, doing Skype, VPN connections to servers, desktop sharing etc. Basically we want to order another DSL line 1.5mbps down / 768 kbps up and join it together with our current DSL connection for a total of 3mbps down/1.5mbps up. Just want to make sure this is possible and if you guys can recommend a router brand and model. To clerify, we don't just want redunacy/fail over, we need to utilize both DSL connections at the same, as if they were one.

We are looking for a good multiple WAN router for our office. We just ordered two DSL 3.0mbps down / 768kbps up lines. Here are the requirements: --> Under $500 --> 2 WAN Load Balanced And Fail Over Support --> Smart enough to handle special session state traffic. Example, if you start a HTTPS session on one DSL line it has to stay on that line. If you start an FTP session connection on one line it has to stay on that line. --> VPN Tunnel Site-To-Site Support, Only need a max of 1 site-to-site tunnel, but nice to have more just in case. --> Standard SPI Firewall With Port Forwarding --> Reserve LAN Static IP's --> Firewall throughput of at least 10mbps

Weird Router Packet
We have a license application client(IBM/LUM) that connects to a license server outside our network. The clients works this way... it binds a random port and tries to connect to the remote IP with UDP port 1515. Through wireshark I could see that it reaches the destionation, although the way back is unreachable. If I add this random port to our router Port Forward rule, it works perfectly. Although this is not a solution cause the port is changing every time. Isnt this strange? Other applications open random ports as well and comunication is two-way reachable. If I connect directly to the internet, it works perfectly as well. What can I try to do with our ZyWall USG300 Router to fix this situation?

Good Budget L3 Router
We're building out a small setup for a client, and we're wondering what's a recommended L3 switch on a budget? Basically, we're going to be colocating in a rack with about 12 servers & a 100 mbps drop, and won't really be doing any major bandwidth (less than 10 mbps). The datacenter was saying something about a /30 handoff for the C class of IPs they're going to be allocating to us. They also said they will NOT handle any Vlans for us, and will just basically handoff the IPs and we will need to route to them and do our own vlans. One thing we need to be able to do is route additional IPs to servers if a client orders them. We were recommended a 3550-24-EMI by a friend, it seems old but if it does the trick, it works. One thing I was reading about it though was PVlans and the 3550 not supporting them. I don't think we'd need PVlans in our setup, just basic 1 vlan per client.

I come across car1 and car2 a lot, but can't quite figure those out. (Example: gigabitethernet6-24.car2.bos1.Level3.net -- the "gigabitethernet" is obvious, as is bos1 (Boston). But car2? And it shows up towards the other end: ae-31-89.car1.Washington1.Level3.net. (Bonus: what's the "ae" at the start denoting?) csw, ebr, mpr, and ash are all common followed by a single number, too. (pos and tge show up on RCN a lot.) cr, dcr, ecr, hr on Savvis?

So what linux based router software is the easiest to use and most educational? Also - I dealing with about 30mb 95th percentile traffic. Peak is 100mb.

Cost Effective Router

We are starting with a 15mbps commit on fiber (via ethernet hand off), and don't plan to exceed 20-30 any time soon, but if we did we need remove for expansion on equipment. What Router/Router Series would you guys recommand for a small budget friendly project, but more importantly something that is very stable? I'm pretty tech savvy, however easy to configure and maintain will be high up on the list.... Also what switch brand/series would you recommend that are cost effective and can handle a decent load?

Router For BGP 100Mbps
We currently have a single 100Mpbs (currently pushing ~40Mpbs) feed from a single upstream provider. Routing is handled by our transit provider. We wish to provide a more resilient setup and are now looking to install our own BGP router(s) and take a second feed from another provider. I have a looked around the Cisco website and this forum but am unsure which model of routers / layer 3 switch we should be looking at. A layer 3 switch looks more cost effective but doesn't appear to support enough routes for BGP without great expense. Would a 2600 router be enough or should I be looking at something higher like the 7600 series?

Redundant Router Setup
I'm in the process to setup a new service with an ISP with the following scenario and need your help. I've got the rack (42U), servers and switches. Only routers has been left and here is that I need your help. I have also 2 ports from the ISP where I can connect my routers. I need to get 2 router devices with auto sync feature in order to be able to setup a redundant plan in case that one of them goes down. Those routers should have firewall features too in order to avoid setup iptables rules for each server. A basic DDoS protection is needed too. I'm going to push around 100Mbit of traffic across the servers but that will happen after 3-4 months from the initial setup. In the first instance no more than 10-20Mbit will be used. I heard a lot about Cisco but got no idea what model is the most suitable for my case. I will probably need a module for DDoS attacks and another one for advanced security IOS from what I read but it is not clear to me.

Router Suggestion - Hundreds Of Peers
for a router than can handle a couple hundred BGP peers, but will not necessarily be pushing a lot of traffic. The router should be able to handle 200-400 BGP peers, but will only need to push around 2-3 Gbit/sec. What would anyone recommend for this specific configuration? I am willing to spend whatever is needed, though I also don't want to just be throwing more money at it than I need to to get the job done effectively.

Configuring A Linux Router/firewall
I run a small datacenter, and we are migrating from Cisco to Linux based routers. This routers should run a firewall, DDOS mitigation rules, CBQ bandwidth limitation, etc.. I know how to mitigate DDOS using tcpdump, also I know how to route.. I just need some advice about the firewall, stopping basic DDOS, fragmented packets, etc.. Should I use APF firewall in this case? Is there a good IPTABLES set of rules I could use? I'm giving up from Ciscos, as I just discovered there are some UDP packets that can easily break them. I tested it last night, and that was it, nothing secure A few traffic (bogus UDP packets) and the router was down for a few minutes.

I know the approximate retail cost, but can't really guess on the residual after 3, 4, or 5 year lease, so it's hard to estimate the approximate payment to expect. I don't want to get a salesperson involved yet because once they have your phone #, they never stop calling, and I'm not 100% certain we're going with the 7301 (versus a Juniper M5 or M7i).

Differences Between Router, Switch And Hub
differences between a router, hub and a switch. I have set up a file/print server using samba on my home network that just uses a simple 4 port linksys router, so I'm relatively familiar with routers. Its my understanding that a hub, is kind of like a router but w/o a "to modem" spot. So you would use a hub if you just wanted to connect some computers to have a LAN party or something, right? Where there'd be no internet connection. Is this correct? As far as switches, I get the feeling they are like routers, only better? Because data centers and companies mostly use switches, not routers? Or am I way off? What exactly is different between a switch and a router. As a supplamental question- I will be starting college next fall, and a friend of mine said that dorm students are not supposed to use routers, but rather switches. Any idea why this would be the case? And also, along the lines of college networks. Say I wanted to take my server with me to my dorm, how would that work? I know this depends on the university, but how would such a large network like that work- would each dorm have its own public IP address? Or would the dorm have one public IP, then each room have an internal IP? Sorry if this is a dumb question, I've really only worked with simple home networking

7800 Router Vs Catalyst Switch
i am thinking about upgrading things at the colo soon and am looking for some comments. my current configuration is like so: my bandwidth is delivered over fast ethernet and it is plugged straight into a cisco 3550 switch. i have the ip range they have assigned me cut up in to vlans the way i need. i snmp poll the switch for traffic statistics with rtg. this works fine, im only working about 10mbit avg so no biggie. well, i am considering picking up another provider (super cheap cogent) to adding it to the pile. i want to get bgp setup and have my own address block assigned by arin (unless my carrier now lets me announce their address space out cogent). getting a ASN isnt a problem, and i have done some tinkering with bgp in the lab. so anyway.. i am having a bit of a time figuring out what would work better for me, a 7200 series vxr router or a 4500 series catalyst. what would be the pros and cons of either one?

Apache + Modem + Voip Box + Router
If I visit my own public IP address, it won't show Apache from the computer running it. If I visit the private IP (http://192.168.1.102/) I can see it fine. If I enter the private IP of the computer it is on, I can connect to it through internet explorer on a different computer in the network. When I visit my public IP, I get "page cannot be displayed". Setup: Modem (bridged) cable goes into VOIP box. Cable from VOIP box goes into router. Cables from router go into computers on network. The IP address of my router is currently 192.168.1.1 The private IP of the computer running Apache is 192.168.1.102 I have forwarded port 80 (the apache port) on my router Here are screenshots of my VOIP box (linksys) and router (dlink) admin pages: ....

Inter-VLANs Router With In/out Policers, Ipv6
Can you make a recommendation for a switch-based L3 router which can - hold a moderate number of routes (interface routes, a few hundred statics + default) - OSPF and BGP - MST - 1024 layer-3 dot1q subinterfaces (or maybe VLAN interfaces) with + traffic policing in and out per subinterface/vlan + VRRP/HSRP/NSRP - IPv4 & IPv6 native - 2x GigE ports - Not tip-over under 1gbps DDoS towards a VLAN interface. I've been using 3560Gs, but they seem to lack the output traffic policing. I'd prefer to have subinterfaces which don't run spanning-tree, versus Vlan Interfaces to a trunk interface which runs spanning-tree. These switches sit at the L3 boundary between two L2 networks. Cost is a big factor; but I also must carry vendor licenses & support contract, if the vendor asserts that not doing so is illegal in US.

Cisco Router For Terminating SMF SC Interface
I have a requirement where one of our partner is planning to connect to our datacenter using a dedicated leased line. As per our partner, they will engage a Leased line vendor for this. This vendor will terminate the leased line ( Single mode fiber -- SC connector) to the Comm room of our Colocation provider. I have next to nothing knowledge about fiber connectivity and have few questions in this regard. Q1. If Single mode fiber is terminated at COLO's Comm room in form of SMF SC connector, what kind of cross connect should we request from COlo's comm room to our cabinet. ( SMF / MMF ) Q2. How are these cross connects terminated in cabinet? Do Colo provider use some kind of fiber patch panel or they simply provide a fiber link with SC/LC connectors at the end of it? Q3. If cross connect needs to be SMF SC then which cisco routers support SMF SC interfaces? Do I need SC-LC patch cable? (I looked at the various option but could only find the following GLC-LH-SM or GLC-ZX-SM for SMF connectivity. I read about these and found that GLC-LH-SM is used for terminating single mode fiber that spans up to 10 km and GLC-ZX-SM is used for terminating single mode fiber that spans up to 70 km in length. It looks as if both of these support LC connectors. Are these the only two SMF connectivity options? Do I need SC-LC patch cable ) Q4. Our partner only tells us that the terminated link will be terminated using SMF SC. How to figure out if GLC-LH-SM or GLC-ZX-SM is required.

Firewall/router For VPS Host Server
we had 2 Xen serverers in colohouse, each with 30 IPs yet. Now we are going to purchase third server and started to think about renting small rack and putting own firewall infront of the servers. Actual bandwidth is 5Mbits for both servers together. We are thinking about to have something like this: Colohouse-->Firewall<-->switch<--->Xen server(s) With scenario we would like to add: 1) traffic monitoring per IP 2) traffic shapping per IP 3) firewalling whole segment of our public IPs FW will get single IP and range of public IPs routed to that IP 4) be able to put one public IP for VPS on to any Xen server What firewall and switch you will recommend for this scenario?

Loading CPanel And WHM (probably Router Problem)
Lately the cPanel and WHM on my server loads very very slowly or not load at all from my pc.. The problem is local. It works from other places.. It's not my firewall (pc-cillin) as it have the same problems even when i disable my firewall.. It's probably my router. I have a d-link DI-524 router. Is it a known problem? I don't understand a lot in configuring it so "open this port" or "close this port" won't help.. I realy need detailed instructions I've tried to play with the filtering settings (adding port 2082,2086) but nothing worked..

Hardware Recommendation For Quagga / Zebra Router
Assuming you were going to build an open source router, what hardware would you use to do so? What factors of the hardware used would make the most performance increase in the open source router? 1.Does the bus speed pay a significant role in the routing capabilities? 2.How much does processor speed and cache size affect the routing performance? 3.Should I use ECC ram, or can I use faster DDR3 ram? 4.Would using a SSD as the primary hard drive be wise as they have extremely fast read times compared to regular hard drives? 5.Would you go with Intel or AMD CPUs? I am assuming that bus speeds play a significant role in the routing capabilities. AMD and Intel seem to rate their buss speeds in a different way. What would you recommend? 6.What type of NIC’s should I use? I know that they should be PCI-E cards because they have the fastest busses right? 7.Does anyone make interface cards for other type of network connections like DS3’s or T1’s for use with Linux systems? 8.Can you rate the performance of a high-speed server running Quagga compared to a Cisco 7206VXR with NPE-300/400 or a 6509 with SUP1/2 cards?
