I am working on fc10. I connect to internet using two connections: with proxy and without proxy. Initially I had some problem in configuring yum for proxy and I resolved it by creating files proxy.sh and proxy.csh in /etc/profile.d with the required details (export_proxy).Now when I connect to my connection without proxy I have some problems .Whenever I try to do yum update I get the following error:
"[URL]: [Errno 12] Timeout: <urlopen error timed out> Trying other mirror. Error: failure: repodata/primary.xml.gz from adobe-linux-i386: [Errno 256] No more mirrors to try." what changes do I need to make in order to use yum in the connection without proxy?

Ever since I upgraded to Natty / 11.04, the quality of my desktop experience has dropped sharply.
One thing that effect me greatly is that I can no longer conveniently switch my network proxy on or off system-wide with single click.
Back in Maverick / 10.10, I could launch gnome-network-properties and switch it back and forth depends rather I am at work or at home.
I have found a similar application, "gnome-control-center network," on the surface of it, it seems to replace "gnome-network-properties" in Maverick. Except that this application doesn't seems do ANYTHING.
As result, I am having the hardest time switching my proxy settings, as I have to do so per application basis (gpodder, pidgin, aptitude, thunderbird / firefox, etc).
ps. I am using Gnome "classic" but Gnome 3 suffers the same issue
Using Ubuntu Linux for some years now I love CUPS functionality to switch on the printer (at least my USB connected HP Deskjet) automatically when a new print job has been submitted to CUPS. This does not work in Fedora 15? Does anyone know how to enable this or has the new CUPS or any other component lost this functionality?

Is this possible and if not can anyone suggest a good way to switch between multiple displays automatically?
I've got an eeePC with a really tiny monitor, so whenever I go (home, faculty, parent's home, friend's home, ...) I attach it to any external monitor I can find.
If it matters my system is like this:
Archlinux
Linux 2.6.36
Xorg 7.6
X server 1.9.2
Intel Corporation Mobile 945GME Express Integrated Graphics Controller (fully accelerated by intel modules)
When I boot up the system, it uses the integrated monitor (LVDS1) only, and I have to manually manually switch to the external monitor (VGA1) using xrandr.
Is it possible to configure my Xorg (or whatever) so that it uses the VGA1 output if present?
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:

View 3 Replies View RelatedI have a laptop that I use in three environments with different monitor setups.
1) At work, I have a 1280x1024 second monitor.
2) At home, I have a 1920x1080 second monitor.
3) In meetings and other places I have no second monitor.
Whenever I switch between these setups, which is at least several times each day, I have to manually change the monitor configuration. I use the nvidia-settings tools.
Granted, it only takes a few seconds. Is there a way to make the system smart enough to automatically detect when a monitor is added or removed, know *which* monitor is attached, and reconfigure the resolution and monitor layouts the way I want them?
Sometimes during the system startup I get this message:

I am using squid proxy server for internet access,
in my office all are using laptop through wifi , so i need to configure the browser proxy setting for accessing internet.
is there any way to setup automatically get the proxy setting as dhcp. I have tried transparent proxy but no success.
I need to access some things in "documents and settings" folders (my windows xp crashed). I believe I need to be root user in linux to do this. I am running a ubuntu linux live (uninstalled) cd. I am new to linux and I do not know if this is even possible. I want to copy some things from documents and settings folder to an external drive (as backup) but I cannot access them as things are now (linux gives me an error when I try) but I would like to do it in gui so I can physically "see" everything and look through it.
View 9 Replies View RelatedAt 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.
Or which environments are installed? Gnome is too big for my older computer.
I want to switch before the desktop loads, as I am using a live CD.
Linux has duplicate address detection mechanism for IPv6 and nothing for IPv4 in kernel. At boot time, initscripts take care to check for the duplicate address but when an IP address is assigned using ifconfig or ip utility, no error is generated.

View 2 Replies View RelatedWe run redundant switches that two nic's on each server connect to. We also run bonding on our servers. Because we have two switches, we can't run lacp or anything. If a switch goes into a crashed state where it doesn't pass traffic but still provides link, bonding thinks the interface is still up and thus will still send traffic through it. Does anybody know a better way to configure the fail over of the interface? This would be a similar situation to somebody using a media converter.

This post has two parts. First the part that might look a little misplaced on this forum, but which I hope someone may still know a thing or two about: I have installed Slackware (alongside Ubuntu and Windows 7) to have something to play around with and hopefully learn a thing or two. I am able to get KDE up and running, but in the interfaces list under network preferences, neither my wireless nor my wired network card shows up. Both cards show up correctly in lspci:

This challenge has caused me to wonder about the second part of this post. What is it that makes Ubuntu good at hardware detection? I know the Linux kernel should detect most hardware, but if that was the whole truth, there would be no difference between distributions in this aspect, correct?
Can the fibre channel switch in the centOS5.3 cluster edition be switched for a regular router or hub?
If so how would one do this? If not why does the switch have to be fibre channel?
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!
View 8 Replies View RelatedI 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 ?
I successfully installed Ubuntu 10.04 on 2 laptops (both are identical in terms of hardware). In addition, I connected both of them (using RJ45 cables) to a switch (just a switch; I don't have a router).

1. SSH to machineA.
2. SSH from machineA to machineB
where machineB is my actual lab machine. neither machineA or machineB allow anything other than SSH, and machineB is only accessible from machineA. However, I really need to run yum on machineB. I have managed to get internet access via Firefox on machineB by creating a series of SOCKS proxy via SSH.
1. machineB: ssh -L 12345:localhost:12345 user@machineA
2. machineA: ssh -D 12345 user@machineC
3. machineB: configure firefox to use socks proxy, localhost, 12345
where machineC has internet without limits placed. This is the only way I have managed to get internet working. I tried using ssh -L all the way from machineB->machineA->machineC but it didn't work (even when setting Firefox to use http proxy). I tried using ssh -D all the way, but again that doesn't work either.
I do have access via Firefox using socks proxy. However, yum update fails to retrieve mirror list, and from what I have found I don't believe yum supports socks proxy directly. Instead, it uses http_proxy / ftp_proxy. how to get yum to go out over the SOCKS proxy I created (same one using in Firefox)? It seems like since Firefox can access the internet and everything without issues, i should be able to get yum to tunnel through the same connection to access everything.... I tried
