[Bug 708493] Re: Can't login anymore: Read from socket failed: Connection reset by peer

[Steve Brown]

Howdy,

I know that in my case, this was definitely an MTU problem, and it
exhibits exactly the behavior stated above.

to test this, call
ping -M do -s 1500 <host>
If it goes through, this is probably not your issue.  If it does not, try lowering the -s value until it does go through.  If the value that you find is lower than the MTU on your interface, this is likely the problem.

The solution would be to change your MTU size on the interface.  You can check this with
ifconfig
and set it with
sudo ifconfig <interface> mtu 1000
