vpn does not work

[Ayush Kanodia]

Hi,

My windows vpn does not work. It asks for the username and password thrice on openVPN, and then says failed to connect. Is someone else facing the same issue?

It would be more easy to debug your problem if you could post the list of errors the VPN application shows.

Sometimes the IITB VPN server is down, but in such a case, the openVPN application silently make reattampts (20 or so) without asking for passwords each time. So I'm assuming you are facing another problem

It asks username/password, says connected successfully and STILL internal sites don’t open. I would suggest boot into Linux, “ssh –X sec...@login.iitb.ac.in –p 5022” with password extvoxacc and then follow on screen instructions to login to mars. You can then open Firefox because you used the –X switch. Voila! Screw VPNs.

Hi,

@Adwait: The log is attached.

@Pratyush: I am doing that on windows now, but I still wanted to figure out why VPN does not work

Thanks,

Ayush

[Pratyush Nalam]

@Ayush, the –X switch doesn’t work on Cygwin/Git Bash. Only Linux will do the job.

I guess this explains it:

AUTH: Received AUTH_FAILED control message

Me too having the same problem in windows! Connection timeout problem.

[Naga Varun Dasari]

Try shrew soft VPN client in windows. Works for me most of the times.

[Adwait Dongare]

Shrew Soft is no longer supported by the IITB VPN servers. As of now, openVPN is the only way.

I also had the same problem and asked the CC for a solution. They gave this solution which works fine.

Try running the OpenVPN GUI as administrator. Right click the icon "OpenVPN GUI" on the desktop and click Run as administrator. OpenVPN GUI will show up in the Notification area of the taskbar. From there connect to the IITB network by logging in with LDAP.

-X is for X11 forwarding.
-D is for dynamic port forwarding.

X11 is the display architecture.
Port forwards are, well, part of the network architecture.

-X will let you run apps on the server, transmit their display to the client in order to show them.
-D will let you use a local port as SOCKS proxy that works as if you were on the server itself.

-X is slow, and rightfully so.
-D isn't, not more than the network itself.

-X is overkill.
-D is just right for the job

@Ranjeet : Oh yes. The Run as administrator thing works. I had somehow skipped it although it was there in the instructions. Thanks Ranjeet.

@Pratyush : I am running it on windows, and its working fine.

TL;DR: Use -D <port number> as a SOCKS proxy, not -X.

Pros: Good speeds, cross-platform (yes, that includes Windows.)

Cons: You'll have to configure a browser. I recommend Firefox. It has that about:config network.proxy.socks_remote_dns thing which Chrome doesn't openly have.
