I'm thinking about adding a linux based router to my cabinet. I have 8 computers so I'm not looking for anything that's tricky. In fact some of this is just for my own education as to what routers can do.
The biggest feature that's important to me is ease of use. I want something that I can configure from a web based menu. 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. Would a box that has and AMD dual core CPU with 8 gigs of ram be a good enough computer to run on?
i got one fully managed ip range from my isp around 256 ips to use on my networks. Basically i want to set up gateway, segment the 256 ips into two parts, each part with 128 ips. detail below
1, nameserver 123.123.123.2 and 123.123.123.3 3, first part gateway 123.123.123.4 and ip use from 123.123.123.5-123.123.123.128 4, second part gateway 123.123.123.129 and ip use from 123.123.123.130 - 123.123.123.255
what i am using? centos 5.2 with vconfig installed
what i did? 1.i add the name server 123.123.123.2 and 123.123.123.3 to /etc/resolv.conf 2,i add the gateway 123.123.123.4 and 123.123.123.129 to /etc/sysconfig/network and added line" VLAN=yes" 3,i edited eth1 with following setting
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 have a task of converting a current Win Server based apache server from multiple IP based virtual hosts to a full name based virtual hosting.I'm famiilar with the steps but I was wondering if there are any gotchas in Windows that I should be aware of. It seems that now matter what I change in the new config it doesn't work or work as expected.
I have a small problem. I have a install directory on my website, who are only for me. I have a password protected directory, and thats no problem to create in Plesk on Linux.
But the main diffrent from Windows based Plesk, are that I can not create a directory there I can browse the files in my webreader. In windows plesk they have a option called Web directory, but I have never seen thats option in Linux plesk.
Are there any easy way to password protect and allow directory browsing in Plesk for Linux? Or do anybody have a easy way to do that?
One option, is to access the directory thru FTP interface in Internet explorer (ftp://mysite/directory). But I want to access the site thru HTTP if possible.
For the first Time now i was trying to grant a User SSH Access via Plesk Panel (chrooted/non chrooted), but it doesnt work out really .. Abonnement > Edit Permissions > Allow Access chrooted (or non chrooted doesnt matter) doesnt change anything when im trying to Login with the created System User by Plesk. Login doesnt work!
Regular SSH Login as root works as always without any problems, but even via "su user" it doesnt works.
Till now I didn't had any Problems with my VPS Setup based on Centos 6.6 and Plesk 12.0.18 #50.
My company and I are currently discovering Plesk on a CentOS 6.6 based system. We are migrating from an old system on which FTP usernames could hold uppercase letters, which apparently is not the case in Plesk 11 (or is it because of CentOS?).
Anyway, as we can't change these FTP account names, I was thinking about creating a rule with mod_rewrite in the proftpd.conf file.
So the question is: how can I reinstall/reconfigure proftpd with this module activated? I don't even know where to find the corresponding package (which repo, correct version, etc...)
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)
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.
I regiested a IP address from one company and I can post my website on internet. that company give me an IP address someting like: 167.23.42.100. Right now My internet speed is very slow, I want to reset my router. If I reset my router, router will produce a new IP address, Does this IP address is same as 167.23.42.100. IF i reset router, do i need to change my website address. I am worry that resetting router will affect my website address(domin name).
Maybe router IP is different as doman name. so I don't need to worry about
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.
I need 1U of space, .5 amp (50 watts) power, one IP, 2.5mbps bidirectional bandwidth (total of 5mbps up + down) and about 10GB of traffic per day each direction (total of 20GB up + down). Would be nice if they have remote KVM along with console (serial) access. Location should be anywhere in USA.
Purpose is to host a VPN router for various remote locations to connect in to. Reliability and good connection (low latency) is important.
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.
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,
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?
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.
We have a project in mind and we are planning on using a Cisco 7140 to push about 80Mbps over ethernet. Do you think the 7140 will be enough or it will get maxed out? (the 7140 is supposed to be like the 7200VXR NPE-300).
The routing would be thorugh BGP with partial routes.
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?
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...).
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?
I'm buying Cisco ASR 1000 router that should handle 2 Gbps bandwidth. Please advice on components, models, etc.
I have a vendor, but I'll appreciate any reference, based on your experience, on where to buy one at reasonable price. I think I can probably get refurbished ASR 1000 or similar as well, if the vendor can guarantee the quality of the device.
