Hi, We have Linux server that we use as a trusted host. So this is the first hop for many unix admins in my company to reach a target server. We are getting intermittent errors lately when we try to ssh. Some times when we are luck to get an ssh session, we get a different error while we try to sudo as root. I guess both of these issues are related. Any ideas? Please suggest. *** error when we ssh through putty *** #Using username "maui". Authenticating with public key "rsa-key-20080325" Server refused to allocate pty tset: standard error: Invalid argument *** when we get in with luck; still get an error while we try to sudo as root *** #more /etc/redhat-release Red Hat Enterprise Linux AS release 4 (Nahant Update 4) #sudo su - Cannot open cloning master pty: No such file or directory open pty failed: Illegal seek Thanks -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
