small office network with Linux CentOS 5.4 internet server. I use Squid 2.6.STABLE21. I have static IP.If I masquerade my small office net FTP works, but if I disable masquerade then FTP doesn't work through Squid.I was trying to stop iptables but the problem was the same.
View 9 RepliesI setup squid with transparent proxy and its working, however, when I reboot the server, the proxy server doesnt work unless I run the following.
Code: # squid server IP
SQUID_SERVER="192.168.1.1"
# Interface connected to Internet
INTERNET="eth0"
# Interface connected to LAN
LAN_IN="eth1"
# Squid port
SQUID_PORT="3128"

I use CentOS 5.4, Squid version 2.6 , squidGuard version 1.2. Squid works properly, squidGuard also works properli. I want to redirect all requirests from [URL] to [URL]. It seems that squidguard works:
Code:
[root@main ~]# echo "http://www.sex.com 127.0.0.1/ - - GET" | squidguard -c /etc/squid/squidguard.conf
http://www.infoborder.com 127.0.0.1/- - -
[root@main ~]#
But if I want to access site [URL] with a browser which is connected to squid, my browser get me the site [URL]
I have installed and tried both squid version as transparent proxy but they just don't work.
I have eth0 which is where my internet comes in and eth1 which is my local network 192.168.1.0/255.255.255.0.
My default firewall policy is to drop input output and forward, i have already set my firewall to accept and workout the squid and it is working.
Here is the relevant rules i have on my firewall:
Code:
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.
I currently have the set up as shown below: [Internet] - [Gateway Appliance] - [Squid Server] - Client Workstations.
I have configured squid 3.1.6 on Ubuntu 10.10 and have got it working. However, When I add the line:
forwarded_for transparent The HTTP Header should remain unaltered (This is my understanding anyway).
What I want to achieve is that when a Client computer connects via the Squid server, it is routed via the Gateway Appliance and out onto the internet. But using the forwarded_for transparent I want the content filter list, to show the source computer as a client IP address and NOT the IP of the squid server.
Is this possible, if so could someone point me in the right direction onto getting it working.
i have a squid proxy on a centos 5.4 64 Bit machine.
i can share internet on my other boxes hosting centos 32 bit and windows by entering the proxy server IP in the network proxy (centos) internet explorer (windows).
but i cannot get mails on my thunderbird client behind the proxy even though i have included ports 110 and 25 in the squid. i v heard it cannot do it as squid is not imap proxy.
I have searched and searched for a reverse proxy solution for non-website traffic. TCP but not http, on ports other than 80, 443, 8080, etc. Basically I just need a TCP forwarder that works with multiple TCP servers, WITHOUT webpage caching features. I do not need or want any webpage caching. Can squid work as a reverse proxy for TCP traffic without http? The other program I came across in searching was HAproxy. Both programs are for http but I am curious if they would work for TCP servers that do not serve webpages.

View 1 Replies View RelatedI have a simple cron job that runs every night & I tested this manually by just running the command as root in bash and all worked fine. It took some time but the crob job finished and I got my results emailed to me perfect / as expected.
Here is root's cron job listing:
Code:
Now I noticed that I never ever got anything emailed to me the following day so I am wondering if perhaps the Cron daemon doesn't have permissions or has an issue running / executing the command rather than when I test the command as 'root'? When I view my logs, I can see the command being executed and don't see any errors however I don't get email results when Cron runs the job rather than me taking the command and running it manually in Bash...then it works. What am I missing?

host - ubunut 1010 desktop 64bit

My ftp server runs vsftp. The ftp passive ports stopped working while iptables is running, so users can't ls their dirs. I know that you need to load the modules of ip_conntrack and ip_conntrack_ftp, the problem is when I modprobe ip_conntrack I get the error: FATAL: Module ip_conntract_ftp not found. No that is not a typo. ip_conntract_ftp? Am I missing something?

I know this version is probably not supported anymore but I can't just format a customer server because it's OS is outdated...I just can't put my sources.list on it because I am on ubuntu 10.10 and it would download updates for the wrong OS probably causing a huge damage on the old one.

View 3 Replies View RelatedI have a computer that I would like to backup the home directory onto a server. I created a script called wien_backup.sh that contains the following:

where wngr403-unix2 is the computer I am backing up, and the script is ran from the server. If I run the script by itself, it works just fine. If I run it as a cronjob, the /var/log/syslog says it ran, but it does nothing.

I have a server that has snmp installed(Version is net-snmp-5.3.2.2-9.el5_5.1). This server has 5 n/w interfaces with diferent ip's. My problem is when i try snmpwalk on to the main interface, in my case "bond0" with the assigned ip address there is no response.
eg: snmpwalk v2c -c nature 172.17.241.190
No Response from 172.17.241.190
But when i run the same query with "localhost" snmpd responds.
eg: snmpwalk v2c -c nature localhost

I have a dedicated server running CentOS 5, Plesk 9.2.2, SMTP Postfix and Courier-IMAP.The issue I have is that on all domains on the server receiving email works fine however sending email never seems to work. This is from email programs, my phone, webmail and PHP. None of them seem to be able to send email. If it is of worth Spam Assassin is running however I don't feel it is causing any problems.

Ergo; She's unable to log on to her workplace computer/server from home.
View 3 Replies View RelatedAfter I finished upgrading Xubuntu from 9.10 to 10.04, I discovered that my keyboard stopped working in X Server. The upgrade process was running smoothly until the last moment, when it produced some error, which I, unfortunately, did not write down. Anyway, the upgrade has completed; uname shows kernel version 2.6.32-31. Now the keyboard works fine if I select a recovery mode at startup, but if I type 'start gdm' from the shell or select the default option in GRUB while booting, the keyboard becomes unavailable right from the login screen. I can log on using the virtual keyboard, but that's all I can do; the keyboard is still dead.
