Fedora Servers :: Squid 3.1.1 Proxy Server Will Not FTP

May 11, 2010

I have 4 servers running squid/3.1.1 proxy server. Since the latest version I can no longer FTP. I have posted this problem in multiple places but have received almost no response. I've found several other post to this problem throughout the Internet which have also gone unanswered. So, once again, I thought I'd give it a try. As I said "I have 4 servers running the newest version of Squid". When I try to access an ftp, any ftp, I receive an error (check attached image). This was never a problem until just recently. Squid should work perfectly find with ftp, it is not a strictly http proxy.

I turned my firewall off just to make sure, still had the same issue. If I jump directly on the server itself with no proxy settings set in the browser it will work fine. As soon as I set the browser setting to access the Squid software I get the same error. I've included my squid config (which is unchanged from the default settings), maybe somebody better versed than myself can point out an obvious flaw. Everything else seem to work just fine, it's only FTP that's a problem.

Fedora Servers :: Reverse The Proxy With Squid?

Mar 14, 2011

I have a reverse proxy set up with squid. I'm going to try and explain what it's doing and I apologize for it being confusing, I'll do the best I can to describe my problem. First, it's for our phone system. We run a ShoreTel Voip system. The owner has decided he wants me to setup MCM (Mobile Call Manager), which from what I can see is an under developed, and almost impossible to get help with Shoretel software. But he's convinced he needs it for his Iphone. It's supposed to, in a nutshell, turn his Iphone into his work phone with all the advantages and doodads that come with it. Apparently, "they have an app for that". On the server side, I need to setup a reverse proxy back into the network on our phone server. Simple enough, I did this with squid. I used the following lines:

Code:

http_port 80 accel defaultsite=172.17.137.7
cache_peer http://172.17.137.7 parent 80 0 no-query originserver name=myAccel
acl our_sites dstdomain http://172.17.137.7

[code]....

Code:

always_direct allow all It most definitely is allowing traffic back to the phone server, the problem is, it hands out my internal server address to the outside client. So for instance, if I connect to the outside routable address with my phone, it will immediately change the url to http://172.17.137.7 which is the inside nat address of my phone server. Which of course doesn't work, since I couldn't browse to that address from the outside. It does however work from the inside of the network, obviously because 172.17.137.7 is accessible from the inside.

Fedora Servers :: Configure Evolution-mail Clients Through SQUID Proxy?

Jul 27, 2011

I have configured router(192.168.1.2) to serve only one machine with IP - '192.168.1.6' and set up SQUID proxy on '192.168.1.6'. I have defined some rules(ACL) regarding connections to internet on SQUID proxy.

I changed the Gateway of rest of machine (192.168.1.60 - 192.168.1.69) from '192.168.1.2' to '192.168.1.6'.

The policies which I defined in SQUID is working properly but 'Linux Evolution mail' client is not fetching mails.

Is I have to do any other settings on 'Linux System' or 'Evolution mail client'.

Ubuntu Servers :: Squid Proxy Very Slow For Web In Default Config?

Jan 10, 2010

I just set up squid for the first time. I have zero experience with proxy servers. I used this guide:[URL](I also looked at a few other guides such as this one:ttp://ubuntuforums.org/showthread.php?t=320733. However, I wanted to most barebones config to start with and the link I used was the simplest.)So now that I have it set up, I'm testing it with FoxyProxy. It is not working well. I went to speedtest.net. The download and ping tests were just as fast as without the proxy, but the upload test fails completely.Furthermore, many web pages load very slowly or not at all. So performance is very mixed, but mostly poor.

Server :: Make Squid 2.6 Stable As Transparent Proxy Server?

Dec 22, 2010

I want to make a transparent squid proxy server in centos. The squid proxy version is 2.6 stable. I made a normal squid server but want to make it transparent so that users do not need to enter the proxy settings in web browser. Even i searched about this on google but not getting it properly.I have two lan cards on centos system. ETH1 used for LAN and ETH2 used for WAN. And in this squid.conf i written "http_port 172.16.31.1:3128 transparent" and i also added a rule in iptables which is "iptables -t nat -A PREROUTING -i eth1 -p tcp --dport 80 -j REDIRECT --to-port 3128" but still i have to enter proxy settings at client's web browser to use internet

Ubuntu :: Setting Up Squid Proxy Server?

Dec 28, 2010

I followed this guide: [URL] and restart the Squid Server with no errors but when I try to SSH into it:

Code:

ssh -L 8080:squidserver:8080 user@squidserver

It just hangs there for a long time, not timing out and eventually (after a long wait) I get this:

Code:

ssh_exchange_identification: Connection closed by remote host

What could be the problem? I can SSH normally into the computer, but not into the proxy server. Do I need to forward the 8080 port on that network?

Server :: Improving Squid Proxy Performance?

Feb 4, 2010

I am starting to get bottlenecks in the loading of webpages via squid. It is not the actual playback of video that has performance issues, this is very good. However, when a webpage is first requested, it is the initial response that takes more than a few seconds to load the page. I am wondering how to troubleshoot the issue as I don't know whether it is squid, the dns lookup, the number of users, RAM, or the bandwidth. Bandwidth seems to be the least likely since the server has a high bandwidth and video streaming appears to have no problems. I do not have caching turned on yet, which would certainly help because I do not want to cache flb, mp3, etc. files and the last time I turned on caching the performance was actually worse. The slow loading of pages has only just beguin to creep into the performance, it wasn't an issue before.

Here is the sample conf i am using for squid:

Code:

Always_direct allow all When using version 2.7.x i was able to make it transparent when i used the below rules:

Code:

I readed the Docs on the squid page but the above rules can't be reproduced to 3.1 and i don't wish to use such rules to make it transparent or hidden so i want some help to figure out why it inst transparent.

Server :: Squid As Reverse Proxy - Too Slow ?

Mar 16, 2011

I've been using squid-cache for a long time for authentication/authorization. It has work fine for years, but now it starts working too slow only in one computer (the others, works fine).

It's configured as a reverse proxy.

I see it can be a DNS problem, but the computer is configured with the same dns servers in resolv.conf that the other computers have.

I use squid 2.6.stable14 on RHEL 4.4.

If I restart the service (service squid restart) it works fine, but 15-20 minutes later, the problem repeats.

Server :: Squid Intercepting Proxy On Bridging PC?

Mar 22, 2010

I am trying to set up squid as an intercepting proxy on a bridging (as opposed to NAT/routing) PC. I followed this guide on freshmeat - however, when I started squid it said the httpd_accel_* lines were unrecognized, so I commented them.

I have the bridging side working alright, but when I try to access a website from a machine using the bridge, Squid gives an error saying it cannot find the site, and only listing the non-domain part of the URL.

For example, if I try to go to [URL] , the Squid error page says it cannot find the server /questions/

I'm using Squid 3 on Ubuntu Karmic. (I don't have any reason for using Squid 3 over 2.whatever, I just picked the newer one).

Also, a side-question - since no doubt someone will ask for my squid config file, what's an easy way to strip the comments so it's not half a mile long when I post it?
