Re: Unable to login in to hp-ux machine 11.23
please do a comparison for the below files with other server which is having same version.
/var/adm/inetd.sec
/etc/inetd.conf
if you did not find any difference please run the below command and try to login.
#mv /etc/securitty /etc/securitty.old

Re: Unable to login in to hp-ux machine 11.23
Thomas:
Both servers having similar entries in /var/adm/inetd.sec & /etc/inetd.conf.
I haven't find the /etc/security file.
johnson:
Find the below o/p:
globaldb:root-/etc>ls /dev/pts | egrep -i '^[0-9]' | wc -w
60
globaldb:root-/etc>ps -ef | grep pty | wc -l
2

Seems that there is something wrong with this device file. Maybe re-creating this would solve your problem.
Did you recently upgraded/re-installed sshd?
