I am using my girlfriend's Windows 8 machine and trying to access a remote machine using ssh. Earlier today PuTTY was working fine, but then I uninstalled some programs that my girlfriend said she never used, and now I get the error "Network Error: Software caused connection abort". There is a question about this here that specifically concerns such issues after a period of inactivity: PuTTY Network Error: Software caused connection abort
This is not the case here. It happens consistently after about a minute, whether or not there's any activity, including right in the middle of typing stuff.
There is no problem connecting to the Internet in general through a browser, and there's no problem connecting to the ssh server using ping. I don't think it's an issue with the particular site because I got the same problem sshing into a different machine.
Of the applications I uninstalled, none of them were system-type applications that should have changed the network settings (although this is Windows, so who knows ...). Reliability Monitor says I uninstalled the following apps: Playthru Player, 3CXPhone, eBay Worldwide, Dropbox 15GB. There was also an AOL app, some WildTangent games, Spotify, etc. (I can't remember exactly what the other ones were; is there a way to see all applications that were uninstalled through Programs and Features?)
I have tried:
- All the solutions mentioned on the page I linked to above (changing PuTTY's keepalive settings,
netsh int tcp set global autotuninglevel=disabled, setting'HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\TcpMaxDataRetransmissionsto 16) - Using different ssh clients (KiTTY, also openssh from Cygwin; same problem in all of them)
- Different ssh servers
Nothing works. Any suggestions for how to troubleshoot this?
