ssh broken?

Thu Nov 8 08:15:00 GMT 2007

Hi,
I also got the same problem since a few days.
I have done a complete reinstall of cygwin, but it didn't help.
I get "ssh: connect to host ... port 22: No error" immediately 
regardless if the address I try towards actually exists or not.
I used wireshark on the destination computer, and saw some traffic on 
port 22 when I tried to connect to it. Havn't looked into it in detail.
I downloaded and installed putty, and it works fine.
Tried to disable firewalls, no change.
I also noticed that I have some problems with the x-server.
startx gives
.
.
_XSERVTransSocketUNIXAccept: accept() failed
And i I try "xhost +" in the opened xterm i get
xhost: unable to open display "localhost:0.0"
Regards
Erik
