Hi, I'm using a cygwin openssh 3.7.1p2, SSH protocols 1.5/2.0, OpenSSL 0.9.7c 30 Sep 2003 to connect to a sshd server : sshd version OpenSSH_3.4p1 Debian 1:3.4p1-1.woody.3 Sometime the connection hang. I've written a little batch script : set USER=u12 echo "start" > log.txt :begin time /T time /T >>log.txt c:\kiwi\bin\ssh.exe -F ssh_config -i .\keys\id_rsa %USER%@green.kiwi-backup.com ls /mnt/data1/%USER%/snapshot goto begin It work fine but sometime, the ssh ls hang for exactelly 2 hour. I think that it's the tcp timeout of the socket. I use this sort of connection in some automatic scripts and it's really annoyoing. Any idea ? S?bastien HEITZMANN
