There can be more than one login on console. But at any gievn time only one will have write acess on console. What error you get when you telnet to machine??

Hello,

Are you sure that one is not the parent of the other? Use ps -ef|grep console and see if PPID of one is PID of other.

check with w -lu there. Refer output with who command also.

check process ID of login shell with ps command too.

Login informations will be maintained on wtmp log. Auditation of login details on versions 11i,11.11 are having problem.

It sounds like you have a very old HP-UX system with a two-user license. To see your current license, type the command:

uname -l

The licenses are counted as:

- one for every login over a serial or modem port

- one for the console (sounds like you are running a workstation and not a server so the workstation's display is the console)

- one for any number of network logins like telnet (ftp is not counted)

Thios means that if you login from your workstation console, you'll consume one license. If another occurs by modem or serial connection, the last license is used and no network (telnet) connections will be allowed. If you login with telnet first, then any number of network users can login.

So, you must either:

- upgrade your user license (not possible if you are running obsolete software such as HP-UX 10.20 or earlier)

- Disable any serial connections such as terminals or modems
