• Forward all traffic through an ssh tunnel

  - by Eamorr

  I hope someone can follow this and I'll explain as best I can. I'm trying to forward all traffic from port 6999 on x.x.x.224, through an ssh tunnel, and onto port 7000 on x.x.x.218. Here is some ASCII art: |browser|-----|Squid on x.x.x.224|------|ssh tunnel|------<satellite link>-----|Squid on x.x.x.218|-----|www| 3128 6999 7000 80 When I remove the ssh tunnel, everything works fine. The idea is to turn off encryption on the ssh tunnel (to save bandwidth) and turn on maximum compression (to save more bandwidth). This is because it's a satellite link. Here's the ssh tunnel I've been using: ssh -C -f -C -o CompressionLevel=9 -o Cipher=none [email protected] -L 7000:172.16.1.224:6999 -N The trouble is, I don't know how to get data from Squid on x.x.x.224 into the ssh tunnel? Am I going about this the wrong way? Should I create an ssh tunnel on x.x.x.218? I use iptables to stop squid on x.x.x.224 from reading port 80, but to feed from port 6999 instead (i.e. via the ssh tunnel). Do I need another iptables rule? Any comments greatly appreciated. Many thanks in advance,

• Blocking HTTPS and P2P Traffic

  - by Genboy

  I have a Debian server running at the gateway level on a LAN. This runs squid for creating block lists of websites - for eg. blocking social networking on the LAN. Also uses iptables. I am able to do a lot of things with squid & iptables, but a few things seem difficult to achieve. 1) If I block facebook through their http url, people can still access https://www.facebook.com because squid doesn't go through https traffic by default. However, if the users set the gateway IP address as proxy on their web browser, then https is also blocked. So I can do one thing - using iptables drop all outgoing 443 traffic, so that people are forced to set proxy on their browser in order to browse any HTTPS traffic. However, is there a better solution for this. 2) As the number of blocked urls increase in squid, I am planning to integrate squidguard. However, the good squidguard lists are not free for commercial use. Anyone knows of a good squidguard list which is free. 3) Block yahoo messenger, gtalk etc. There are so many ports on which these Instant Messenger softwares work. You need to drop lots of outgoing ports in iptables. However, new ports get added, so you have to keep adding them. And even if your list of ports is current, people can still use the web version of gtalk etc. 4) Blocking P2P. Haven't been able to figure out how to do this till now.

• Do I need to have a proxy server to have HTTP over SSH?

  - by Johnes thomas

  I want to use HTTP over SSH since in my university most of the sites are blocked. I have my own server to which I can using SSH. What I'm doing right now is have a squid proxy run on the server on a particular port. Then connect using putty to my server via ssh and create a tunnel from a certain local port (which I will enter as proxy server in Firefox) to the squid server. So in putty the configuration is like this for the tunnel: source port:8080 destination:localhost:3128 I want to know is there any other way other than running the squid proxy on my server to tunnel the packets? Thanks.

• In CentOS 4.3 Webmin 1.3000 bandwidth monitoring is eating disk space. How to delete those files?

  - by Silkograph

  I maintain Linux server being used for Mail, Squid and DNS service. Recently I observed that something was eating server disk space. But at last, today I caught the culprit which was consuming the disk by storing large number of files. On this server, Webmin 1.300 is installed. We use Squid proxy and Sarg to monitor Internet access. I always manually clear Sarg generated files under /var/www/html/squid for last few years. But I never realized that Webmin is also storing some kind of bandwidth log files in its' directory structure. I have noticed that under /etc/webmin/bandwidth/hours it has stored more thousands of files since year 2007 totaling about 17 GB. We have used 40 GB HDD for this server machine. My question is how can I delete those (/etc/webmin/bandwidth/hours) files safely?

• iptables secure squid proxy

  - by Lytithwyn

  I have a setup where my incoming internet connection feeds into a squid proxy/caching server, and from there into my local wireless router. On the wan side of the proxy server, I have eth0 with address 208.78.∗∗∗.∗∗∗ On the lan side of the proxy server, I have eth1 with address 192.168.2.1 Traffic from my lan gets forwarded through the proxy transparently to the internet via the following rules. Note that traffic from the squid server itself is also routed through the proxy/cache, and this is on purpose: # iptables forwarding iptables -A FORWARD -i eth1 -o eth0 -s 192.168.2.0/24 -m state --state NEW -j ACCEPT iptables -A FORWARD -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -A POSTROUTING -t nat -j MASQUERADE # iptables for squid transparent proxy iptables -t nat -A PREROUTING -i eth1 -p tcp --dport 80 -j DNAT --to 192.168.2.1:3128 iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 3128 How can I set up iptables to block any connections made to my server from the outside, while not blocking anything initiated from the inside? I have tried doing: iptables -A INPUT -i eth0 -s 192.168.2.0/24 -j ACCEPT iptables -A INPUT -i eth0 -j REJECT But this blocks everything. I have also tried reversing the order of those commands in case I got that part wrong, but that didn't help. I guess I don't fully understand everything about iptables. Any ideas?

• Sarg report error

  - by amyassin

  I have a proxy server that runs Ubuntu Server 11.10, Squid 2.7.STABLE9. I installed sarg (version 2.3.1 Sep-18-2010) to generate reports using the ordinary apt-get install, and added a cron job to generate a report of the day every 5 minutes (that will overwrite the 5-minutes-older one): */5 * * * * /root/proxy_report.sh And the content of /root/proxy_report.sh is: #!/bin/bash /usr/bin/sarg -nd `date +"%d/%m/%Y"` > /dev/null 2>&1 And I added another cron job to generate a full report every hour at :32 (not to collide with the 5 minutes job): */32 * * * * /root/proxy_report_full.sh And the content of /root/proxy_report_full.sh is : #!/bin/bash /usr/bin/sarg -n > /dev/null 2>&1 And I added a small script to remove the yesterday full report (the full report that ends in yesterday that won't be overwritten by the new today full report) in /etc/rc.local to run at startup: /usr/bin/rm_yesterday.sh &>> /var/log/rm_yesterday Where /usr/bin/rm_yesterday.sh: #!/bin/bash find /var/www/sarg/ | grep `date -d Apr1 +"%Y%b%d"`-* | grep -v `date +"%Y%b%d"` | xargs rm -rf * Apr1 is the starting date of the proxy... ** I've placed it in /usr/bin to be mounted early at startup... That arrangement went OK for about a month and a half, except for one time I noticed some errors and reports wasn't generated, and fixed that by making an offset (the two minutes in 32 of the second cron job). However, it then started not to generate reports anymore. By manually trying to generate it it gives the following error: root@proxy-server:~# sarg -n SARG: getword_atoll loop detected after 3 bytes. SARG: Line="154 192.168.10.40 TCP_MISS/200 39 CONNECT www.google.com" SARG: Record="154 192.168.10.40 TCP_MISS/200 39 CONNECT www.google.com" SARG: searching for 'x2f' SARG: getword backtrace: SARG: 1:sarg() [0x8050a4a] SARG: 2:sarg() [0x8050c8b] SARG: 3:sarg() [0x804fc2e] SARG: 4:/lib/i386-linux-gnu/libc.so.6(__libc_start_main+0xf3) [0x129113] SARG: 5:sarg() [0x80501c9] SARG: Maybe you have a broken date in your /var/log/squid/access.log file When I looked to /var/log/squid/ folder, I noticed that it contains some rotated logs: root@proxy-server:~# ls /var/log/squid/ access.log access.log.1 cache.log cache.log.1 store.log store.log.1 So maybe sarg installed logrotate with it? Or it comes with the standard Ubuntu? I don't remember I installed it manuallly. The question is: What could've gone wrong? Does it have something to do with rotating the log? How can I trace the error and start generating reports again?

• Squid3 not caching simple request and response

  - by Nick Spacek

  Hi folks, I've pared down my squid.conf to try to figure this out: http_port 80 accel defaultsite=host.to.cache cache_peer ip.to.cache parent 80 0 no-query originserver acl our_sites dstdomain host.to.cache http_access allow our_sites refresh_pattern . 1 20% 4320 Requests are being proxied correctly, so that's a start. Here's a request: GET http://host.to.cache/path?some_param=true Accept: */* Accept-Charset: ISO-8859-1,utf-8 Accept-Encoding: gzip,deflate,sdch Accept-Language: en-US,en Connection: keep-alive Host: host.to.cache User-Agent: myuseragent And the response: Connection: keep-alive Content-Length: 585 Content-Type: application/xml Date: Thu, 06 Jan 2011 18:33:11 GMT Via: 1.0 localhost (squid/3.0.STABLE19) X-Cache: MISS from localhost X-Cache-Lookup: MISS from localhost:80 The response has no caching-related headers, but I thought that refresh_pattern would set a default behavior for responses without caching-related headers. For my test, I wanted to cache everything for one minute at minimum. Am I missing something obvious? I did take a peek at this question: Squid isn't caching ...and ran through the page here: http://www.mnot.net/cache_docs/ briefly, but didn't see anything relevant (not to say that there isn't, I could have missed something). Thanks for any help.

• Redirect without changing URL

  - by Coobadivin

  Here's the setup. We have a hardware load balancer with an http virtual cluster. Let's call this virtual cluster example1.com. This virtual cluster load balances between two squid reverse proxies which are also on the same physical servers as the web servers. Squid listens on 80 and points to itself as the cache_peer web server which listens on 81. We also have a standalone web server which we will call example2.com. What we are trying to do is create a subdirectory on example1.com called example1.com/example2. This will point to example2.com, but we want our users to stay at example1.com/example2 in their browser. So, it's like a redirect without actually being a redirect. How the hell do I go about doing this? Is this even possible? I'm looking at squid docs in the meantime. example1.com is running a proprietary web server - not Apache :( We can't host example2.com's content in example1.com's file system. These are two very different platforms.

• Best way to cache apt downloads on a LAN?

  - by Ken Simon

  I have multiple Ubuntu machines at home and a pretty slow internet connection, and sometimes multiple machines need to be updated at once (especially during new Ubuntu releases.) Is there a way where only one of my machines needs to download the packages, and the other machines can use the first machine to get the debs? Does it involve setting up my own local mirror? Or a proxy server? Or can it be made simpler?

• SquidGuard and Active Directory groups

  - by Massimo

  I'm configuring a Linux proxy with Squid and SquidGuard to filter Internet traffic. I know how to authenticate users against Active Directory in Squid, and then how to filter access for users using SquidGuard. The question: how to use Active Directory groups in SquidGuard instead of plain user names? My goal is to be able to configure rules like "members of this group can go anywhere" or "members of this group can only visit certain sites". I know SquidGuard can't manage group membership directly, but it can do LDAP searches on its own; but the syntax to look up wheter a user is member of a given group seems to be quite cryptic, and I couldn't find any good documentation around.

• How do I rewrite *.example.com to www.example.com?

  - by Lekensteyn

  In my network, I've some Ubuntu machines which need to download files from nl.archive.ubuntu.com. Since it's quite a waste of time to download everything multiple times, I've setup a squid proxy for caching the data. Another use for this proxy was rewriting requests for archive.ubuntu.com or *.archive.ubuntu.com to nl.archive.ubuntu.com because this mirror is faster than the US mirrors. This has worked quite well, but after a recent install of my caching machine, the configuration was lost. I remember having a separate perl program for handling this rewrite. How do I setup such a squid proxy which rewrites the host *.example.com to www.example.com and cache the result of the latter?

• Single ipv6 from /64 subnet

  - by PartyPete

  I have a newb question I'd like to ask. We have an dedicated server and we got an ipv6 /64 block. We want to use squid to make proxy and use those IP. And my question now is: Is it possible to use only one IP out of range? for example: let's say I have a range of IPs ffff:ffff::/64, and want to use only one address from it: ffff:ffff::1/128 or ffff:ffff::2/128 but whenever I set squid like this I always get from 'what is my ip' services whole subnet which is again ffff:ffff::. What I want to achieve is to get from those 'what is my ip' services to send me back IP ffff:ffff::1 (or 2 for that matter) Am I doing something wrong?

• How to setup equivalent USVIDEO.ORG DNS-Proxy on Linux

  - by Gary

  I have a VPS in the USA running Ubuntu. I want to setup something similar to http://www.usvideo.org Basically, USVIDEO is a DNS service that allows Canadians to access American content like Hulu, Netflix, NBC, and etc (restricted by geographical IP). Here is how I think USVideo does it: Clients (PS3, XBOX, PC) specifies the DNS server(s) as specified on USVIDEO.org's website. If the DNS request is a video/audio site such as Netflix or Pandora, forward the request to a proxy. Otherwise, for all other requests, forward it to a different DNS server. If the specific video/audio URL is requested, return the address of the proxy server, which in turn relays traffic to the destination video/audio domain via the U.S. gateway so that it appears that the access is coming from a U.S. IP address. Once the DNS request has passed the U.S. IP address check, their proxy server steps out of the loop and lets the video streaming site contact you directly to start the video stream. This trick relies on the way that the video streaming sites check the country of your IP address once up front, but don't actually check the country of the destination IP address while the video is streaming. What is elegant about this solution is that a VPN Tunnel is not required to bypass geographical IP checks from certain websites. All that is required on the client side is to specify the DNS server (the VPS). If a certain site is geographically locked, just forward the traffic to a proxy, and that's it. These sites can be specified in the DNS entries, or perhaps in the proxy service to redirect the DNS request to its own proxy. I believe what I need to setup something similar is Squid Proxy, IPTables, and DNS. What I need help is how to exactly approach this? Would Squid Proxy be setup as a transparent proxy?

• Ways to parse NCSA combined based log files

  - by Kyle

  I've done a bit of site: searching with Google on Server Fault, Super User and Stack Overflow. I also checked non site specific results and and didn't really see a question like this, so here goes... I did spot this question, related to grep and awk which has some great knowledge but I don't feel the text qualification challenge was addressed. This question also broadens the scope to any platform and any program. I've got squid or apache logs based on the NCSA combined format. When I say based, meaning the first n col's in the file are per NCSA combined standards, there might be more col's with custom stuff. Here is an example line from a squid combined log: 1.1.1.1 - - [11/Dec/2010:03:41:46 -0500] "GET http://yourdomain.com:8080/en/some-page.html HTTP/1.1" 200 2142 "-" "Mozilla/5.0 (Windows; U; Windows NT 6.1; C) AppleWebKit/532.4 (KHTML, like Gecko)" TCP_MEM_HIT:NONE I'd like to be able to parse n logs and output specific columns, for sorting, counting, finding unique values etc The main challenge and what makes it a little tricky and also why I feel this question hasn't yet been asked or answered, is the text qualification conundrum. When I spotted asql from the grep/awk question, I was very excited but then realised that it didn't support combined out of the box, something I'll look at extending I guess. Looking forward to answers, and learning new stuff! Answers doesn't have to be limited to platform or program/language. For the context of this question, the platforms I use the most are Linux or OSX. Cheers

• How to make my Ubuntu an internet gateway for my Android phone

  - by yacine

  I want to use the internet of my school on my Android, the problem is they have a Squid proxy, and many applications on my phone don't use the proxy at all. The obvious solution is to install a transparent proxy on my Android to force all applications to connect through it. The problem is that I need to root the phone to make it work, and I don't want to do it because it's not really my phone and rooting is a little risky- Another solution, which is safer, is to make my computer run as a gateway, so I put my Ubuntu IP in the gateway parameter of the phone. I'm running a small proxy on my ubuntu (cntlm), so I redirect the Android traffic to it. I did it with "iptables" as follows: iptables -t nat -A PREROUTING -s 10.0.1.118 -p tcp -j REDIRECT --to-ports 8888 iptables -t nat -A PREROUTING -s 10.0.1.118 -p udp -j REDIRECT --to-ports 8888 10.0.1.118 is the IP of the phone, 8888 is the port of cntlm (proxy on my PC). Now, on the phone: When I enter www.google.com on the navigator I get nothing (web site not found, error message of Firefox). But, when I enter http://74.125.143.101 (IP of Google) I get an error message from the school proxy (so it worked in some way – my PC redirected the traffic of the phone to the Squid proxy). The error message is : The requested URL could not be retrieved while trying to process the request get / http/1.1 host 74.125.143.101 user-Agent ... ... I think the problem is in the "GET" header,it should be GET 74.125.143.101 HTTP/1.1. But I don't understand what's happening, and I'm a certified CCNA.

• How do I tunnel an HTTPS proxy through a virtual machine (VMWare)

  - by Kyle

  I have a personal setup at home using VMWare Workstation. I also have a set of Virtual Private Machines that run Squid, and therefore provide me HTTPS proxy tunnels. Using Proxifier, I can tunnel all traffic for given applications through these tunnels. However, I also have a few virtual machines for dev/staging/experimentation/etc. I generally just use NAT to provide Internet access to the machines, and if I need to use these proxies, I can just setup Proxifier (or a Linux equivalent) to pipe the traffic through them. No problem. But... I got to thinking: Wouldn't it be great if I could assign these proxy tunnels to a virtual machine, so that when I start up the VM, it has instant-on access through the tunnel and not my local connection? (EDIT: Of course, it would USE my local connection, but it would tunnel traffic through the proxy.) To be more clear: I want a solution that binds the proxy to a VM, so that when I start the VM, I don't have to use a proxy client to connect to the tunnel - I am already piping all traffic from that VM through that proxy. I did a bit of searching, and the closest thing I could find was this: How to route public static IP to a virtual machine on a vmware ESXi host? Which wasn't all that applicable. The proxies are protected by user/pass but do not filter by IP. Again, they are HTTPS proxies setup through Squid. Any ideas on how to make this happen? Thanks a ton.

  what reverse proxy server will direct traffic to healthy servers whose health is based on a result string?? ideally i'd like something like dnsmadeeasy or ultradns - lol - but for reverse proxy i have looked at pound, delegate, ha proxy, squid, varnish, nginx, apache, and cherokee but can't see that they will work - they only test for HTTP result code scenario client request www.aaa.com www.aaa.com is a reverse proxy reverse proxy looks at "test.php" on server 1.aaa.com, 2.aaa.com and 3.aaa.com for result string "OK" if the server is "OK" then proxy requests to them help!

• configure squid3 to set up a web proxy in ubuntu12.04

  - by Gnijuohz

  I am in a LAN and have to use a proxy given to access the web in a very limited way. I can't even use google, github.com or SE sites. However I can use ssh to log into a server, which I have root access so basically I can do anything I want with it. So I was thinking that maybe I could use that server as a proxy so I can visit sites through it. I tested it using ssh -vT [email protected] which gave a proper response. And In my computer I can't do this. Also I tried downloading something from the gun.org using wget, which can't be done in my computer too. And it succeeded on that server. I don't know if that's enough to say that this server have full access to the Internet. But I assumed so and I installed squid3 on it. After trying some while, I failed to get it working. I got this after I run squid3 -k parse 2012/07/06 21:45:18| Processing Configuration File: /etc/squid3/squid.conf (depth 0) 2012/07/06 21:45:18| Processing: acl manager proto cache_object 2012/07/06 21:45:18| Processing: acl localhost src 127.0.0.1/32 ::1 2012/07/06 21:45:18| Processing: acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 ::1 2012/07/06 21:45:18| Processing: acl localnet src 10.1.0.0/16 # RFC1918 possible internal network 2012/07/06 21:45:18| Processing: acl SSL_ports port 443 2012/07/06 21:45:18| Processing: acl Safe_ports port 80 # http 2012/07/06 21:45:18| Processing: acl Safe_ports port 21 # ftp 2012/07/06 21:45:18| Processing: acl Safe_ports port 443 # https 2012/07/06 21:45:18| Processing: acl Safe_ports port 70 # gopher 2012/07/06 21:45:18| Processing: acl Safe_ports port 210 # wais 2012/07/06 21:45:18| Processing: acl Safe_ports port 1025-65535 # unregistered ports 2012/07/06 21:45:18| Processing: acl Safe_ports port 280 # http-mgmt 2012/07/06 21:45:18| Processing: acl Safe_ports port 488 # gss-http 2012/07/06 21:45:18| Processing: acl Safe_ports port 591 # filemaker 2012/07/06 21:45:18| Processing: acl Safe_ports port 777 # multiling http 2012/07/06 21:45:18| Processing: acl CONNECT method CONNECT 2012/07/06 21:45:18| Processing: http_port 3128 transparent vhost vport 2012/07/06 21:45:18| Starting Authentication on port [::]:3128 2012/07/06 21:45:18| Disabling Authentication on port [::]:3128 (interception enabled) 2012/07/06 21:45:18| Disabling IPv6 on port [::]:3128 (interception enabled) 2012/07/06 21:45:18| Processing: cache_mem 1000 MB 2012/07/06 21:45:18| Processing: cache_swap_low 90 2012/07/06 21:45:18| Processing: coredump_dir /var/spool/squid3 2012/07/06 21:45:18| Processing: refresh_pattern ^ftp: 1440 20% 10080 2012/07/06 21:45:18| Processing: refresh_pattern ^gopher: 1440 0% 1440 2012/07/06 21:45:18| Processing: refresh_pattern -i (/cgi-bin/|?) 0 0% 0 2012/07/06 21:45:18| Processing: refresh_pattern (Release|Packages(.gz)*)$ 0 20% 2880 2012/07/06 21:45:18| Processing: refresh_pattern . 0 20% 4320 2012/07/06 21:45:18| Processing: ipcache_high 95 2012/07/06 21:45:18| Processing: http_access allow all I deleted some allow and deny rules and added http_access allow all so that all the request would be allowed. After configuring my computer, I got this error: Access control configuration prevents your request from being allowed at this time. Please contact your service provider if you feel this is incorrect. And the log in the server showed that my TCP requests had all been denied. So, first of all, is what I am trying to do achievable? If so, how to configure the squid in the server so that I use it as a proxy to surf the Internet? My computer and the server both run Ubuntu11.04. Thanks for any help~
