Router Suggestion - Hundreds Of Peers

Jul 22, 2009

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.

Mod_evasive Suggestion For High Traffic Server

Mar 12, 2008

The server gets around 25k unique visitors per day, but one website in particular allows hotlinking and uses a lot of bandwidth. Last time I checked...according to whm apache status page, I was getting 180 requests per second. Not sure what time it was though. So it might be higher at a different time of the day.

Recently got mod_evasive installed, but I didn't want it to block out legitimate users. Currently it's set to this...

<IfModule mod_evasive20.c>
DOSHashTableSize 3097
DOSPageCount 5
DOSSiteCount 100
DOSPageInterval 2
DOSSiteInterval 2
DOSBlockingPeriod 10
DOSBlockingPeriod 600
</IfModule>

what a better configuration would be? When I run the log I already see it block out a bunch of IP's. I don't want to lose any visitors to this program, but I do get ddos a lot.

2+ Years Experience - Blurstorm (review) - Need Suggestion For New Hosting

Aug 5, 2008

I've been with Blurstorm for 2+ years and I can say alot of good thing about the company and support. I even gave them a 5 out of 5 of webhostingjury and went as far as to say I would give them 10 out of 5, so you can imagine how happy I WAS with their service until this past week.

I has been an absolute hell. First the server kept blocking my ip and locking my session, when I would try and upload files with filezilla. They suggested to try a different ftp software which I did and it worked. At first I thought it was my computer/isp/router, so I tried it from my friend computer, same thing. And by the way, I never had this problem before. So I didn't make a big deal out of it, even though I prefer filezilla.

Now a couple of days ago, seems every time I would browse the pages or try and use the admin section the site would go down, or at least that's what I thought. After sending 8 hours going back and forth with support(Robert) through their support ticket system, because there is not live chat, Robert tells me there is nothing else they can do because they dont see any errors happening and I would have to pay a 3rd party monitoring service to find out what the problem is.

I mean I completely understand that if they cant find the problem but the site was working couple of days ago and I havent done anything different, so something must of happened on their end. Also I uploaded the site onto a friends server with a different hosting company and the site works perfectly with no problems.

Now being left high and dry with no help from Blurstorm, I did a couple of more test and found out that the site was not down but was blocking my ip and locking my sessions and the only way around it was for to renew my ip and to try again, but that would only help me for a couple of mins before it locked it again. Again, I also tried it from my friends computer and same thing. So I know for a Fact that it has to be from Blurstorm's end. I told that the server was blocking my ip and locking my session and haven't heard from them for over 16 hours, which is horrible customer service compared to the way they were before.

The main reason I stayed with blurstorm was for their support and quick response and I've referred them a boat load of business, and this was not the first time i've had problems with the server and support but I didnt make a big deal out of it and from now on no more referrals.

Well there is my review, sorry it's a little lengthy but just wanted to give an indepth review.

Second part - need suggestions for new hosting

From what I've gathers from searching that are reliable

precision effect
jaguarpc
innohosting

which would you recommend from those or any others?

And my site is based on joomla 1.5 + virtuemart so it should work with it.

Switch Suggestion, 1000Mbps Ports, 2 X 1Gbps Uplinks, Simple Layer 3

Jun 24, 2007

I'm investigating "suspects" that could be used in a server access environment. My requirements are:

*24 or 48 10/100/1000 Mbps Ports
*Atleast 2 x 1000Mbps uplinks (fiber preferred)
*SNMP-enabled for remote bandwidth polling @ ports and uplinks
*Simple Layer 3 allowing for per port rate limiting
VLAN creation support would be a plus, but not required

The switch needs to be able to handle ~1000Mbps of constant usage

I would be open to using non-Cisco switches as well.

Hundreds Of Messages In Mail Queue

Mar 10, 2007

I have hundreds and hundreds of messages in mail queue waiting delivering. Log file says:

connect to remote.host[000.000.000.000]: server refused to talk to me: 421 4.7.0 remote.host Error: too many connections from my-servers-ip

delivery temporarily suspended: connect to remote.host[000.000.000.000]: Connection timed out

(I replaced real IP addresses with 000, my-servers-ip and hostname with "remote host")

It happends only with one host (the most popular free email provider in my country). All emails to yahoo, gmail etc are being delivered without any problems.

What does it mean - too many connections from my server? I have a busy dating website and php script sends out a lot of email notifications (for example - when users get new instant messages). Anyway, I never heard that email providers limit the number of emails from the same server. During the night time all messages from mail queue are being delivered, but at day time this number sometimes grows to 1000.

I have Postfix installed.

Yahoo Is Blocking Hundreds Of Our Legitimate Emails

Sep 9, 2008

We are a small ISP with about 5000 users. Only a very small percentage of our users can send email to Yahoo, and even that is sporadic.

Hundreds of our users' legitimate emails are rejected daily with the following message:
421 Message from (208.66.56.9) temporarily deferred - 4.16.50. Please refer to help.yahoo.com/help/us/mail/defer/defer-06.html

I have filled out "Yahoo! Mail Delivery Issues Form" a few times. I get the following automated response message:
--------------------------------------------------------------------
Hello,

This is an automated message regarding your recent request for Yahoo!
Mail Customer Care support. We have received your message and willYa
respond within the next 48 hours with an answer.

Thank you for reaching out to us. We look forward to helping you!

Sincerely,

Yahoo! Customer Care

**Please do not respond to this message as no one will receive it.
--------------------------------------------------------------------------

But I never received a response from Yahoo and they continue rejecting our users' legitimate emails.

After reading many forums and blogs, it appears that they are doing the same thing to many other small ISPs and companies with their own email servers.

This practice can interrupt many legitimate business communications and hurts many small businesses.

Sendmail :: Hundreds Of Files Left In /var/spool/clientmqueue

Mar 10, 2008

RedHat Box running Sendmail 8.13.1, php 4.4.7, only 1 domain on it running the most recent vBulletin version and vBulletin has been successfully setup to run mail through GMail. The files in the domain directory have been cleaned up, ie. old unused files, etc.

Every night running into the same issue. Server goes on VERY high load due to sendmail. With hundreds of following processes:

apache 29425 0.0 0.0 6712 2576 ? D 19:31 0:00 /usr/sbin/sendmail -t -i
apache 29426 0.1 0.0 6688 2500 ? D 19:31 0:00 /usr/sbin/sendmail -t -i
apache 29427 0.2 0.0 7080 2572 ? D 19:31 0:00 /usr/sbin/sendmail -t -i

I also have hundreds of files left in /var/spool/clientmqueue

I am a little confused, is the clientmqueue directory mail coming into the server or mail that is leaving the server?

If it is incoming mail to the server, is there a way to stop or minimize it's effects?

If it is outgoing mail, is there a way I can chase it's origin?

I would shut down sendmail, but there is 1 email address on the domain that receives mail.

Router

May 26, 2007

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

Feb 21, 2007

getting my own AS number, but this seems to require also a router. I dont 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.

IP And Router

Jan 10, 2007

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

A Multiple WAN Router

May 17, 2009

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.

Mutliple WAN Router

May 19, 2009

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

Router VS Switch

Feb 13, 2008

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 For BGP 100Mbps

Mar 18, 2007

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?

Router And A Firewall

Oct 31, 2007

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.

Router Performance

Jun 12, 2007

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.

Which Cisco Router To Use

Jul 11, 2007

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

Jun 13, 2007

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...).
