[Linux-cluster] RHES4 box does not prompt for password after entering login id at console

[sunhux G]

Pressing Ctrl-Alt-Fx   where x is one of the numbers,
I got into another virtual console which showed the message:

SCSI0 (0:0) : rejecting I/O to offline device

Is the above message related to the login issue?


I've just managed to login to another Linux box on the same subnet
& tried "ssh -v a_userid at problem_Linux_box_address" & the remote
connection was closed, screen display is as follows :

[root at svrname ~]# ssh -v myuserid at 172.16.x.y
OpenSSH_3.9p1, OpenSSL 0.9.7a Feb 19 2003

ping to the problem box is Ok
