| Main Office: SCO OSR 5.0.6 with LAN, DSL Internet connection,
| static IP address, VPN router
| Branch Office: Win2000 Prof with LAN, DSL Internet connection, static
| IP address, VPN router
| I have a VPN tunnel from the branch office to the main office. I use a
| telnet login (Termulator telnet client) from the branch to the main
| office and run a character based application at the main
| office. When I login at the main office, I get assigned a pseudo tty,
| ttyp0 for the first login, ttyp1 for the next, and so on.
|
| Unfortunately, I occasionally lose the DSL connection momentarily, and
| I lose the telnet login at the main office. This causes a problem:
|
| When I login again, I get assigned the next pseudo tty, i.e.ttyp1
| because the ttyp0 is not released by the system. That is, the who
| command still shows the first login, ttyp0, as connected. Since I have
| several users logging into the main office, I quickly reach my 5 user
| license limit.
|
| Any ideas how I can prevent these "zombie" logins?

Try the 'ptyclean' script at ftp.armory.com.
