CVS/Telnet, DNS Client from behind a proxy


Hi,

I wanted to use CVS for getting the latest versions of some of the softwares I use, but I'm facing a problem getting it to run. The problem is not with cvs but with the fact that I am behind a proxy.

If I try to cvs, I get the following error:
Code:
root@knapsacker:/home/koodoo# cvs -z9 -q -d :pserver:anonymous@cvs.sv.gnu.org:/sources/gcl update
Unknown host cvs.sv.gnu.org.
root@knapsacker:/home/koodoo#
So, I figured that I'll have to setup my Linux box as a DNS client by making changes to /etc/resolv.conf etc.


We are given i.p.'s like 10.10.20.204 and all our traffic is routed to the proxy. So we do not have any direct connection to the internet.

The default gateway has an i.p. of 203.200.130.1 Earlier if I changed my i.p. to the same class as the default gateway's (something like 203.200.130.79) I could ping it. Back then I got telnet to work by setting up /etc/resolv.conf.

Now, we cannot ping the gateway. So I believe we are only connected to the proxy. Is there any way that I can use CVS from behind the proxy?

Thanks in anticipation,
Regards,
Shishir.

looks like many recent cvs clients contain http_proxy support, but as an overall solution you might like to look at something like stunnel which you can use to route generic network traffic securely via an http proxy.

cvs + http_proxy: http://www.cygwin.com/ml/cygwin/2003-05/msg01280.html

Hi,

Many thanks for your reply
I read the link you had referred to. I also searched for other cvs clients with http_proxy support. One solution that I got was to connect to some Sourceforge mirror using a tunnel and then use CVS.

I forgot the link to the site from where I read this. But it was using tcl to create a pipe to the Sourceforge mirror (which supported these kinds of pipes to allow cvs from behind proxies/firewalls.... cvs-ssh). The command to create the pipe was :
Code:
tclsh tlspipe.tcl -proxy http://10.10.11.1:80 -local localhost:22 -target http://cvs-ssh.sourceforge.net:443
where tlspipe.tcl was a script that was provided on the site.

The problem that I am facing with this is that, it requires a package tls1.4. So I download the package. When I extracted it I got a folder tls1.4 with the following files :
Code:
tls1.4/
libtls1.4.so*  pkgIndex.tcl  tls.tcl
Now, I did not know how to install this. A slocate tls on my system revealed a folder /lib/tls. So I did two things.
Code:
1) Copied the three files into /lib/tls and ran ldconfig. But the script still complained that package tls 1.4 was required.
2) Copied the folder tls1.4 in /lib/ and ran ldconfig, and the script again complained.
I did not know how to install that package, so maybe I did not install it properly or the script was probably flawed.
Was that the right way to install that package? There was no documentation and I could not find any on the internet.

I'll now try and use some other tunnelling software and see if I can connect to that Sourceforge mirror and get cvs to work.

Thanks for all the help.
