I am trying to set up my squid3 proxy as a transparent proxy - right now, I have to manually configure browsers to access via proxy. I understand that I have to put some rules into Iptables and also some further directives in the squid.conf.
I have a couple of specific questions. The proxy server is running on a Ubuntu 10.04 workstation and this machine also acts as a dhcp server for the network. I have just one subnet , namely 192.168.0.1-254 There is only 1 network card. Is it much easier to put in a second network card or is it just as easy to configure the existing lan card as a dual IP?
Is it necessary to configure these 2 IP's ( whether they are via 2 lan cards or dual IP on single card ) to be on different subnets. i.e ETH0 192.168.0.1 and ETH1 192.168.1.1 or is ok to have something like ETH0 192.168.0.1 and ETH1 192.168.0.254 ( where ETH0 is the one facing the LAN and ETH1 points to the modem router / switch i.e The Internet ) Where specifically do I save the Iptables rule configuration file and what must I call it ?

So I've always added an export line in the /etc/profile that has the proxy server for our organization. Now there is a warning in that file that I should use a custom .sh in the profile.d folder. Can I just create a myproxy.sh with the export http_proxy="insert my proxy" line in it and call it a day or do I have to do some crazy shell script?

I'm trying to install Gentoo on a virtual machine (VirtualBox installed on my debian squeeze).
My connexion at home is veeery slow, so I wanted to do it at work (don't judge me!), the thing is I' behinf a proxy.
I tried the command
Code:
export http_proxy="proxy:port"
but couldn't ping anything. On the other hand, when i use
Code:
links www.google.com -http-proxy host:port
that works...
So i was able to download the stage3 file and start preparing the system, but I have some troubles when it comes to use the provided tools (the tool to add a mirror can't retrieve the list for example, and I guess I could not emerge anything either)

I have a DHCP/PXE server behind a firewall. It mounts partitions on the file server on the corp. network on the other side of the firewall. Every box that PXEs also mounts partitions on the main file server.
I was hoping I could change them to mount from the DHCP/PXE server, so that server could cache and cut down on the requests through the firewall, as well as the sessions that the firewall must track.But it seams a little strange to try to export directories that are simply NFS mounts on another server already.

I've tried to read many of the topics in this forum first and tried to find a solution to my problem, but can't find one.I'm testing CentOS 5.5, it's the first time I'm using a CentOS Linux release.I'm trying to configure the proxy "client side " on it and cannot find how to do it.On other Linux release I've used the ENV variable like "http_proxy" or "HTTP_PROXY" etc etc.This time, I don't know why but it doesn't work.I've put the name and @ip of the proxy in /etc/hosts and tried different version upper/lowercase of "http_proxy" "HTTP_proxy" "ftp_pr.." but it doesn't work.If I configure manually Firefox and puting the name or @ip of the proxy we have on our network, it works.But if I try to use ENV variable it doesn't work...

I've two internet based server ( xx.xx.xx.xx and yy.yy.yy.yy ) The Y server is running VNC server and is responsible for answering to VNC sessions. But I need to hide the IP of Y server so I want X server to be as VNC Proxy and redirect all VNC sessions to Y server.
I guess the best way is to use iptables but actually I can't get it working so

I am trying to change the configuration of sendmail so that I can relay mail through google smtp server as suggested here.
First I ran 'm4 sendmail,mc > sendmail.cf' with the original .mc file that came with Fedora 10. There was no error.
I added the following lines.
Quote:
TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
FEATURE(`authinfo','hash /etc/mail/auth/client-info.db')dnl
define(`SMART_HOST',`smtp.gmail.com')dnl
define(`RELAY_MAILER_ARGS�, `TCP $h 587′)
define(`ESMTP_MAILER_ARGS�, `TCP $h 587′)
I ran ''m4 sendmail,mc > sendmail.cf' again and got this message:
Quote:
m4:/usr/share/sendmail-cf/mailer/procmail.m4:33: ERROR: end of file in argument list
I did not change anything in the procmail.m4 file. What do you think caused this error?

I'm using RHEL 5.4 and trying to use the system-config-kickstart to generate a ks.cfg file with all the settings already appeneded. After running the "system-config-kickstart --generate ks.cfg" command, the file gets created but it's missing the firewall configuration, partition information and so on.
How can these settings also be generated with the system-config-kickstart?

What I'm trying to do seems pretty straight forward but I can't seem to find any documentation on this searching the "internets" but I think I'm getting mixed in with all the other proxy documentation.
What I'm trying to do is basically replicate the proxy settings from a desktop machine to a server machine. I have Ubuntu 10.04 Desktop running fine on a corporate network using the Automatic Proxy Configuration option and supplying the appropriate URL that I pulled for a corporate issued windows machine. I would like to do this on Ubuntu server 10.04 as well.
What I've got so far is coping out the proxy information from the .pac file and setting the http proxy value directly but I want to follow the URL so that the system follows any changes that come down the road. how to integrate a .pac (Proxy auto-config) url into ubuntu server?

I'm building a new file/media server for my household to use, and would like to hear the experiences of others, and suggestions, or links to appropriate howto's. I'll be using two (2) 250 GB Western Digital RE4 drives mirrored via mdadm RAID 1 for the Operating System. The storage area will be handled by four (4) 500 GB Western Digital RE4 drives in a RAID 5 array, managed by an Areca 1210 controller.
What I'd like to configure is a basic Samba file server, on which we have individual user folders, and a shared drive. As well, I'd like to add the ability to manage our movie collection so it can be accessed by the Boxee Box attached to the television. Twonky looks promising (and I don't mind paying the $19.95 for something that works well). However, as this is new to me, there may be other solutions out there that are better, and easier to administer. Moving forward, I'd like to explore the feasibility of configuring LDAP on this machine to authenticate users on the network (perhaps even integrate the mail server somehow), and the remote users (only two) who VPN into the network using the pfSense firewall appliance. There are no Windows servers, so Active Directory is not a factor.

We have been struggling with a problem with the mysql-server package. This might be in the wrong category because our problems are with it on x86_64. Where the problem happens variables that should populate from the my.cnf don't, on other servers, they do, the my.cnf files are identical except for the server-id
The problem occurs on some of our machines but not others. All are using the mysql-server-5.0.45-7.el5.x86_64 The ones that work, when you connect with a client respond with server version 5.0.45-log source distribution The ones that don't work respond with 5.0.45 source distribution
It's unclear what the differences are between the two source versions and how we wind up with two different versions. One thing that might be involved, the mysql package is installed with both the i386 and x86_64

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.

I have a recent install of Fedora14, and wanted to have outbound email sent to a smtp server elsewhere on the local network. I found the System->Preferences->Email Settings app and created a mail account with an smtp server. Now I am able to use mailx, mutt, and sendmail -- all send email correctly to the external server.
But I don't like being reliant on the GUI apps and wanted to know how this was done -- what system config files were affected. Assuming that my "smtp.xxx.com" server should show up somewhere, I grepped /home, /etc, and /var, but can't find it anywhere. On a whim I went into Evolution, deleted the mail account, and rebooted, but email STILL works. Where is this configured?

I did a yum update this morning that included a dnsmasq update. Subsequently, for an unrelated reason, I restarted dnsmasq, but it failed because /etc/dnsmasq.d didn't exist. It looks like my /etc/dnsmasq.conf file now includes "conf-dir=/etc/dnsmasq.d" at the end. Since dnsmasq was starting and I didn't remove dnsmasq.d, I assume this line was added by the update. Commenting the line resolves the issue.
An alternative hypothesis, given that I don't really know what the state of /etc/dnsmasq.conf and /etc/dnsmasq.d/ was before the update, might be that the directory did exist, but was removed by the update. I find this the least likely of my 2 stated hypotheses. (There are other hypotheses, but I think they are even less likely). Am I correct is concluding the conf-dir line was added by the update? If so, shouldn't the updated RPM create the directory during install?

I've been racking my brains over the past few days trying to figure out why my NIC card (network interface card) won't show up in the ifcfg-eth0 file.When I configure a new server (like this one) I always go to:/etc/sysconfig/network-scripts/ifcfg-eth0 and from there I usally see the name of my NIC's manufacturer's name and the hardware MAC address.Then it's only a simple process of entering the server's IP address, netmask and gateway and I'm up and running in no time...But not in this case! the ifcfg-eth0 file is completely blank! There's not ONE single line of config info in it... (?)The server runs an Intel core 2 duo (dual-core) CPU with 1 gig of RAM.
I've even re-formatted the drive and re-installed Centos 5.1 on the darn thing 3 times and it simply won't work.The server cannot resolve when I do a wgetIt also gives me a 'resolution problem in the named configuration'.What I don't understand is that the 2 small LEDs on the Cat 5 cable lights up and flash at what appear to be regular intervals here.

I have been struggling to configure a squid proxy server on my ubuntu 11.04 VPS.
Following these instructions[URL].. it is all good BUT I don't want to have to SSH tunnel into the server. Just want to have a proxy set in my proxy server settings in firefox/chrome. Even lock the proxy to certain static IP addresses so no one else can use it except IPs I designate.
1. Can this be done without a VPN or SSH tunnel ?
2. What is the best way to put some security on the proxy server ?

My ISP seems to be having some configuration problems cos of which I cant download certain files (mostly exe and msi and some rpm files) as the download either doesnt start (firefox download window showing "Starting..." all the time) or download gets stuck at some point of time.
However I have access to my college computer through SSH using public key authentication and my college computer has internet access 24x7. I would like to be helped with 2 things:
How do I use the internet through my college computer? Like when I use the internet, the requests go through my college computer so it must appear that the requests come from my college computer IP while I use firefox from my home computer How do I configure yum to download packages through my college computer? I want to setup yum to use the IP of my college computer to download the packages.

I have access to a server via ssh. I'm allowed to install things in my userspace. Furthermore, I'm allowed to use the bandwidth. I paid for access to this server, so they're pretty much ok with me doing things with my space. They told me not to store over 20 GBs of data, and I've kept to that rule.
Basically, I want to be able to turn it into a proxy. So, in a way, I want to redirect all of my traffic to that server. If I have a request, it goes to the server, and any replies come directly to my box.
So, this would be a proxy, right? I only have SSH access, I think. Maybe I have some other forms of access, but I can't remember.
How would I go about doing this?
Here's what I have in mind:
(my box) ----request---> (the server) ---> {internet}
(my box) <----reply/incomingdata---- (the server) <---- {internet}
