Ubuntu Networking :: Necessary To Edit Network Proxy In 10.04 LTS?
Jul 6, 2011
I need to set up network proxy for Ubuntu 10.04 LTS (system->prefernces->network proxy)? In fact I can connect to internet using a modem without worrying about it but will it be better if I do? In firefox, should I edit proxy setting? the options are: no proxy, auto detect proxy, use system proxy, manual proxy, and there are severl proxies like HTTP proxy etc. Does proxy setting has anything to do with security?

How can I edit the system proxy setting using the terminal? Which file contains this settings? I want to edit this automatically using cronjobs, cause from 8-5 I need to use a proxy, but at home I don't need the proxy. How do I fix this?

Using xubuntu 11.04, how do I maually give myself a static IP address and other IPv4 settings? I see the edit connections panel and saved a setting there but can't see how to use that setting. The only useable setting when I'm connected by ethernet is Auto eth0.

I'd like to use NetworkManager on a freshly installed CenntOS 5 on laptop Lenovo ThinkPad T61p. I followed: [URL] Everything went OK, until I selected my active LAN connection in "Edit Connections". After clicking on "Edit", it's not possible to change anything - all is grayed-out. I'm guessing it's a permission problem. But I don't know the internal structure of NetworkManager and what files to look at. I was also expecting that after stopping the network service "Syetem->Admin->Network" would be inactive, but it isn't. Shouldn't the old network manager be uninstalled as well?

My work uses a proxy server to mediate connections to the internet. However, changing the proxy settings in NetworkManager seems to have no effect. When I change the proxy settings in firefox from "use system proxy" to the actual proxy settings then it connects fine - but I would much rather be able to change the system proxy so that it works with all applications.
This is not confined to firefox - I have the same problem trying to use wget in gnome shell. However ftp works fine. I have just looked at the environment variables and it appears that NetworkManager is not setting the http_proxy variable (it is however setting ftp_proxy and https_proxy).

I am using Debian 5 and I have some networking experience, however I want to learn to do this the best way possible. I have a Debian box with two nics and I want to connect that to a switch and use my Debian box as a router basically, as well as having a firewall setup within that too.
Should I use iptables to set up nat or the route command or what? I just want to know the group of tools to use in order to set up my network. Network diagram: Internet <------> Debian Box <----> switch <----> hosts I found some guides but they are for linux 2.4 and i'm not sure if they are right.

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 would like Windows laptops to use a proxy to connect to the network so I can check network activity and see if any malware is trying to connect and where it is trying to connect to. So on my Ubuntu desktop I would like to install something as simple as possible to be used as a proxy, I've seen squid but does that only handle http requests? Does that handle streaming requests and such as well? This so I can see the source of some media that's being played in flash or pps.tv

I think there is an application which lets you set the proxy settings for all applications. I remember seeing something like this in Gnome's network menu but now I'm using XFCE.

I've just installed OpenSuse 11.2 64-bit and, on the whole, I'm pretty happy with it. I'm connected to the network and I am posting this from my new system. However I cannot get any software updates or install new packages
I'm behind a (non-authenticated) proxy and, obviously, Firefox has no problem.
If I use Online Updater I just get error messages like this:
PackageKit Error repo-not-available: Failed to download ./repodata/primary.xml.gz from Index of /update/11.2
(but the site is available in Firefox).
I have tried manual updates through Yast (after setting the proxy) and get pretty much the same thing.
So far I have set the proxy in:
Firefox
/etc/sysconfig/proxy
/etc/PackageKit/PackageKit.conf
Computer -> Yast -> Network Services -> Proxy (That has a test function which confirms it is working).
Applications -> System Settings -> Network Settings (This tells me that the network settings are controlled by NetworkManager and can't be modified by Yast).

Well this is what I am trying to do:
I have a home network with 5 pcs that have Windows XP. I have another computer that has Ubuntu 9.04 server, Squid, and Dansguardian.
The proxy server is able to monitor and report all websites that have been visited. The report is sorted by the ip address from each of the windows pcs.
This is my question:
Is there some software that can be installed on the proxy server that will act as a keylogger...monitoring the keystrokes that are being typed in on the Windows pcs and then generate a report, sorted by ip address, of the keystrokes for each of the windows pcs.
I know that I can install a keylogger on each pc, but I think that it would be better if it was on the proxy server monitoring all the computers.

im looking at changing the computer systems over to Ubuntu, at a scout campsite im staff at. i have sorted some filtering out with dansguardian.
but how do i limit the powers of users, so remove all the administrative side and most importantly stop a user changing the network proxy setting.
i have used ubuntu before but not for a while, so im a bit of a newbie atm.

I need to have Opensuse 11.2 use my proxy server here in the office and it is by hostname/ip:8080 only not HTTP. The problem is using Yast2 I don't have the option of using the proxy that way it wants http. I've been using opensuse on and off since 9 (great flavor BTW my favorite) Easy as you need it to be and just as complicated as you want it to be, a perfect mix.

The proxy I set is not being used or recognized by some apps. For instance dropbox would be able to detect the proxy settings i set using yast>network>proxy while firefox would not recognize it. In firefox i tried using the automatic proxy and using the system proxy. Either of the two won't detect it. However, when I manually set it in firefox's preference it would work. For empathy the proxy is not recognized as well. In addition, can I set the proxy in the empathy app itself? I could not locate it. Also the online updates and repository checks recognizes the proxy I set up.
By the way I am using GNOME 3 as my DE. I would also like to share that when I use the network settings > proxy of gnome 3 none of the apps recognize the proxy.

I work behind an ISA proxy. I have to authenticat with domainuser. When defining proxy settings with yast, I cannot put "domainuser" in the URL, so I add it in text mode in /etc/sysconfig/proxy for all protocols. Example: [URL] Then I have to logout/login in order yast to work.
BUT:
- I cannot add communauty repositories.
- zypper fails
In order to make zypper and adding repositories to work, I have to suppress one of the two back-slash like:

I installed openSuse 11.4 (KDE). It was excellent - everything was working great except for Subversion which use to work fine on 11.3 (command line is broken on 11.4, Eclipse/Subclipse works fine on both).
Subversion kept going to the proxy server instead of going directly to our internal Subversion server. I tried (1.) setting the proxy settings in Yast with excluding for our Subversion server, (2.) tried adding the usual settings in ~/.subversion/servers (which worked fine in 11.3). I could not check out on the command line from the local server, I can check out from external servers, eg: Google.
(I installed from the live CD download. I think this is using something some plasma widget thing for the network management.) Why is Subversion not using the usual ~/.subversion/servers file for its settings in 11.4 (KDE)? What is it using and how can I make it not use the proxy server? (Someone else mentioned his Subversion only started working after he used some Chrome plug-in to change the proxy settings but had no idea why?)

My box has to connect to internet using specified http proxy.I have set proxy in both kde control center and yast2 control center. They both tell me the proxy works fine. But when I really try to use yast2 to update my system, it report an error:
Code:
Failed to download ./repo/repoindex.xml from [URL]
History: - [AbstractCommand.cc:195] URI = [URL]
Even I try
Code:
export http_proxy=http://XXXX
yast in command line,the error still exist.
In debian apt-get and slackware slackpkg,my proxy works fine. So I am sure it is not my fault and maybe it is a bug of yast2.

If I configure my OpenSuSE 11.2 system to use a proxy server in the YaST Proxy module, do I still need to configure my browser (i.e Firefox) to use these proxy settings, or is it done automatically under the covers?
