I have to ssh to a remote machine in Europe from Asia every day for my work. But Putty freezes sometimes at totally random times and I have no choice but to close and re-open a new ssh session. It's frustrating especially when I'm editing something or executing a long running program.

I know the question really doesn't have much details ('cause nothing seems to be wrong with the network at all). Has anyone experienced this sort of issue with Putty and had resolved it?

Thanks for your time!
