I have a netbook running Fedora 10 that i use for work, whilst at work i move around allot of schools. Each have varying proxy settings etc... So i was wondering if it was possible to set the system proxy (the one in System->Preferances->Internet And Network->Network Proxy) from bash. That way i can write a script that looks at my IP (each school has a diff ip e.g. 10.x.y.z) and then sets the system proxy accordingly.

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 1 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.
i setup yum to use my proxy (/etc/yum.conf , /etc/profile.d / KDE network setting)and it works great.
but rpm does not.(the command rpm) how do i setup rpm to use the same proxy yum is setup with ??
how do i get yum, KPackageManager to use System Proxy Settings for there network access ? by proxy i mean it's a program that uses my phone as the proxy.here is the command adb forward tcp:8080 tcp:8080
now i got it to work for firefox like this localhost 8080 for all protocols.did the same in KDE proxy settings localhost 8080 for all protocols..just need to know hot to configure yum and kPackageManage
to use it as well?

View 1 Replies View RelatedI 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?
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.
View 4 Replies View RelatedI have set up many Dansguardian/Squid proxy servers. All of them have been on a network where I could use Microsoft Group Policies to force the proxy settings on each machine. The entire setup is quite easy, surprisingly robust, and reliable as hell.
My Dentist talked to me today and asked for something different. He wants to set his office up as a wireless hot spot for his patrons, and he wants their surfing directed through a proxy server. I plan on putting them on a completely different subnet and independent router. Now, since I won't have the convenience of GP I'm wondering if there is a way to force all internal Port 80 traffic through the Proxy server but obviously not the Proxy itself. I would like to use the router to do this and not the Linux box. Is there a low cost home router like Linksys or Netgear that will do this?
I use fedora 12 now, and I have set network proxy in system->preferences->network proxy,but I can't using yum to install software.

But when want to see what hapenning in tunnel between router and squid - there nothing...squid configuration is ok - was checking before try to make it transparent.
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).
My skill in fedora linux is all acquired by reading online and trial and error. I manage to set up my squid 3.0 proxy server in fedora 11. It is working smoothly as I wanted it to be. I have one client who is running bittorrent that drags all the bandwidth of our network.The problem is I cant make my server work tranparently. I want to make transparent proxy so that it can support my wireless router and I want to control the bandwidth to a fair level for everyone without them knowing.
Please somebody help me configure iptables in step by step, specifically in fedora 11. And all other necessary configuration needed to run my transparent squid 3.0 proxy in fedora 11.I know there's a lot of Linux Genius here that can help. Please help me I needed it badly.

I have also try to forward the traffic coming on 3128 to 80 but its not working:
I can ping a host on my LAN successfully, but I cannot ping [URL]... for example. I have disabled the firewall and set http_proxy and can browse the internet with "Use system proxy settings" checked in Firefox. I am unable to update with yum either, but I am not sure if this is a side effect or not. I have run a trace on my ip address as I am browsing the internet and I can see the sites I am visiting on our web appliance. However, if I try to ping or update no requests are hitting the proxy so I don't think that is the issue.

View 1 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've been doing some security testing in a lab environment that does not have direct internet access. It's actually a little complicated: From home to connect to my lab machine, I
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

is there a way to force wget to use a specific squid proxy when making connections ? - I use a squid proxy normally, but I need this specific request to go via a different one. I dont have to use wget, I just need a way to test squid's blocking rules by requesting various pages through it, this proxy is not my normally proxy on the network and so I cant rely on wget taking the environment variable.
Also, this is as part of a script, so anything that avoids editing wget config files would be best. - Perhaps curl can do this ? - currently im using the exit code of wget to determine if the connection was made.
I just installed the Lucid server, set IP address, Default gateway and Preferred DNSs and need to be able to use apt-get.

View 3 Replies View RelatedI'm having an issue on multiple Lucid boxes where I can't get proxy ARP to work. This is to be used in conjunction with openswan IPSec. I've enabled forwarding and disabled sending/accepting ICMP redirects for each interface as per openswan's requirements. I've added the proxy arp lines for all, default, eth0, and lo to sysctl.conf:
Code:
net.ipv4.conf.eth0.proxy_arp = 1
I then connect the IPSec client, and I have connectivity to the server. When I try to ping (or otherwise access) something else on its subnet, I reach the intended target, but then it ARPs for the sending machine, and the Ubuntu server doesn't respond to the ARP.
I have an ARP entry that looks like this, added via arp -s 192.168.254.100 -D eth0 -i eth0 pub:
Address: 192.168.254.100 (the correct virtual IP for the client)
HWtype: *
HWaddress: <from_interface>
Flags Mask: MP
Iface: eth0
Best I can tell, everything is in order... I can listen in with wireshark on the server and see that it's receiving the ARPs, but I can't get it to respond to them.
On Ubuntu, I know that a user can set a global proxy setting (through a gui, Network Proxy) which will affect all protocols (right?). However, I have set up a server box (no gui) and would like for most of its ports to not go through a proxy. Instead, I'd only like the activity that transmission-daemon does (but not the web UI) to go through a proxy. Is this in any way possible?
