Hi Guys, I did tons of search on what problems might be, but it doesn't seems to be the cases that I have searched even though it looks similar. 1. ssh from Freebsd_A to Freebsd_B: I got "Read from socket failed: Connection reset by peer" error. 2. ssh from windows xp (putty) to Freebsd_B: logs me in fine 3. try to ssh from Freebsd_A to Freebsd_B again, got the same error message, and now I can't log in from windows xp (putty) to Freebsd_B any more, unless I reboot the windows xp machine. WIERD!!! I check the tcp wrapper thing, the hosts.allow is All : All : allow. So that's not the case. I made sure all of the KeepAlive entries are set to yes, but still no luck. Please help... Thanks in advance!
