Fedora Networking :: How To Configure 14 As Caching Proxy
Apr 3, 2011
ran an internet cafe and last week my windows server got fried because of power surge. Now i got Fedora 14 running on another PC and i want to set it up as a full caching proxy server, so other computers can connect through it to the internet. I have 2 network cards inside.I'm really new to Linux and now learning my way around. I managed to install squid but don't know how to configure it to suit the purpose above

Is there anything like a persistent caching proxy available in linux for me to configure, ie not public? (persistent meaning the cache remains in hard disk between reboots) Is it possible that it NEVER looks for any update to a page that is available in the cache?

I will be relocating to a permanent residence sometime in the next year or two. I've recently begun thinking about the best way to implement a home-based network. It occurred to me that the most elegant solution might be the use of VM technology to eliminate as much hardware and wiring as possible.My thinking is this: Install a multi-core system and configure it to run several VMs, one each for a firewall, a caching proxy server, a mail server, a web server. Additionally, I would like to run 2-4 VMs as remote (RDP)workstations, using diskless workstations to boot the VMs over powerline ethernet.The latest powerline technology (available later this year) will allow multiple devices on a residential circuit operating at near gigabit speed, just like legacy wired networks.
In theory, the above would allow me to consolidate everything but the disklessworkstations on a single server and eliminate all wired (and wireless) connections except the broadband connection to the Internet and the cabling to the nearest power outlets. It appears technically possible, but I'm not sure about the various virtual connections among VMs. In theory, each VM should be able to communicate with the other as if it was on the same network via the server data bus, but what about setting up firewall zones? Any internal I/O bandwidth bottlenecks? Any other potential "gotchas", caveats, issues? (Other than the obvious requirement of having enough CPU and RAM).Any thoughts or observations welcome, especially if they are from real world experience in a VM environment. BTW--in case you're wondering why I'm posting here, it's because I run Debian on all my workstations/servers (running VirtualBox as a VM for Windows XP on one workstation).

The problem is that he did not specify exactly where in /etc/profile. I am trying to make a custom spin of F12 but I cannot do it behind the proxy as it is now.

Am using Fedora 15, in which i was able to configure the proxy server and authentication. i confirmed this by configuring web broswer and it works. Now the problem is that i want to deploy it out to other computer system(client) i dont want to use the transparent proxy because the Proxy Authentication will not work.
I even tried to configure a DHCP server if it will work but i cant still configure for other computer system to work.

how-to configure squid proxy server. I still haven't been able to find a solution. I want to set up squid as a open http proxy server. So people from other networks can connect through the proxy without having to login.Do I have to use iptables to reroute http traffic to squids proxy port? I have forwarded the port in my ISP modem so I know thats working, its the squid config that has flaws or iptables locally.

I'm trying to configure a reverse proxy for Oracle Database connections. What I have:
Host outside --> Reverse proxy --> Oracle Database
The "Revese proxy" has two IP, one for local and another for outside.I've tried with iptables, but unable.Now I'm trying with "redir".When I do a tnsping database, it works and says OK. But executing sqlplus user/pass@database, it tries to connect but time later I receive a timeout. What i do is a redir from port 1521 in "Reverse proxy" to 1521 in "Oracle database" why this doesn't work or any other way to do it?

I've set up a caching nameserver on my laptop running Fedora 11. The problem with this is that NetworkManager always overwrites the entry that points to the local nameserver. NetworkManager no longer respects /etc/dhclient.conf or at least its scripts run after dhclient.conf. Also it doesn't respect /etc/sysconfig/ network-scripts/ifcfg-* setting of DNS{1.2}.The man page of NetworkManager describes scripts that run in /etc/NetworkManager/dispatcher.d which can be run when interfaces are brought up and down. I've written a script that will put the entry needed for the local nameserver.

I've tried the following to configure internet access:
My question is how can I configure internet access through proxy system wide for all applications and commands?

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'.

I have Ubuntu 9.10 PC on my home network acting as a VPN gateway. It is using vpnc & iptables to provide access to the remote network - other computers on my local network have routing rules in place to go via the Ubuntu gateway if trying to reach an IP on the remote network. This works just fine, except DNS lookups for names on the remote network don't work.
I'm trying to solve this by using Bind9 on the gateway, so it can act as DNS for the local network. I don't want to create excess VPN traffic or load on the remote DNS, so I want the gateway to forward the lookup to my ISPs DNS first and if the name is not found then try the remote network DNS. Is this possible, or is there another (better) way around this? The Bind9 configs seem to admit multiple DNSs, but use them in a failover sense - only using secondary DNSs when the first one in the list is not reachable at all.

I am currently working on a project at work to do caching across a windows network (web traffic thorugh squid and windows updates with WSUS). It is proving to be an interesting learning project.This got me thinking about my home network. Currently I am running 8 Fedora Computers (with the very real possiblity of more in the forseeable future).
Oviously running "yum update" on every computer and having them download these updates directly on each computer eats a lot of bandwidth on the external link. I would like to know if there is a way to set up a proxy server (or something else for that matter) to cache yum downloads. This way when I deploy a new machine, or run updates, I can save time and bandwidth by only downloading the packages too my LAN once, instead of nearly a dozen times.

My router is crap. If I use DHCP it sets all the computers DNS to itself and all DNS requests get cached in the router. It even starts to loose some DNS request if to many are made at once. On my windows PCs this isnt a problem I just set DNS to google's public DNS servers (8.8.8.8 & 8.8.4.4) and bypass my router and ISP alltogether but when i go to pref>network_connections i have to either set DHCP or manual, there is no option to set DHCP with custom DNS.
I'm sure there must be a way to do this in terminal, can someone tell me how?
I'm using ubuntu 10.10.

I recently installed Ubuntu 9.04 and I'm having issues with apt-get and proxy configuration. Upon initial install I attempted to set the proxy configuration through the GUI and opted for the "manual proxy" configuration. Part way through entering the proxy server name I decided to use the "automatic proxy" configuration option instead. I checked this radio box and entered the URL to automatically configure the proxy information.
At this point everything seeemed to work fine. I ran "apt-get update" and, partway through the update process, I decided to abort the update by pressing control-c. Now I am unable to use apt-get to perform any updates. It gives me several errors stating it is unable to resolve "www" (which is the partial name of the proxy server I began to enter before deciding to use the auto configuration option).
No problem I thought...I'll just go into "/etc/apt/apt.conf" and change the name. Except the name in the apt.conf file is correct. I brought up "synaptic" and changed the network configuration there (as it had the same issue) and now synaptic works fine. I am also able to use the GUI Update Manager to update my system. Still apt-get update fails. Here is one of the error lines it spits out:

I have a question to masters of Apache. In my operating system (CentOS 5) I have installed two Apaches. One is Apache (port 80) from repository where I planning to configure proxy and second one is Apache integrated(port 8090) with KnowledgeTree software. The problem is that when I am trying to configure proxy reverse it simply doesn't work.
This is link to KnowledgeTree software:
- http://127.0.0.1:8090/knowledgeTree
This link I would like to rewrite with proxy like this:
https://myserver.com/knowledgeTree
(HTTPS dont forget)
In my ssl.conf in VirtualHost part I have created something like this:
Code:
<IfModule mod_proxy.c>
<Proxy *>
Order allow,deny
Allow from all
</Proxy>
ProxyRequests off
ProxyPass /knowledgeTree http://127.0.0.1:8090/knowledgeTree
ProxyPassReverse /knowledgeTree http://127.0.0.1:8090/knowledgeTree
<Location /knowledgeTree/>
ProxyPassReverse /
</Location>
</IfModule>
When I am trying to connect I see only: Unable to connect. Firefox can't establish a connection to the server at ifdocu.contaxt.biz:8090.

I've been trying to make myself anonymous, but I cant find 'Tor' anywhere, tried 'yum & kpackagekit' neither have it. I did find 'Privoxy', installed it, set proxy for HTTP and HTTPS in Firefox, but it says 'unknown proxy' when I try to use it! I've been to the Privoxy web site and read through the 'User manual', but most of it is 'geek' to me!

At the moment I have a proxy and all the users have to configure it in the browser to access internet. I want to make the users able to browse even without configuring the proxy in the browser. but eventually it should be received in the proxy rather than giving an error to the user. I heard with transparent proxy I can redirect all the traffic from a particular network, to a particular host( ie my existing proxy).
I tried this using firewall rules. But then the existing proxy doesn't understand the protocol of the requests. I heard that it should be in the kind of proxy protocol.

I am looking into creating a web caching server for myself using fedora 10. I believe I need to use squid for this but it seems to have a lot of features. Basically, all I want for now is to be able to cache web pages that I and my network users use the most, increasing access time and lowering the load on my internet connection. Can squid do this and can someone point in the right direction on an article on how to configure such a thing?
