Telnet & lastb

[Michael Selvesteen_2]

Here goes our problem

Platform : HP-UX 11.11

When an user telnet to the server and the authentication fails after max tries, the lastb reports max tries + 1 attempts.

eg:

root pts/tf Sat Sep 4 10:42
root pts/tf Sat Sep 4 10:42
root pts/tf Sat Sep 4 10:42
root pts/tf Sat Sep 4 10:42

( for only three failed attempts)

Is it the correct behavior or any way to avoid this.

Thanks for the help

Michael

Hi Michael,

Check this document from ITRC database.

Document description: Some failed login(1) attempts are recorded twice (as lastb(1) shows)

Starting with 11.00 patch PHCO_24083 the last failed attempt is
recorded twice in /var/adm/btmp and thus lastb(1) displays it twice:

Hope this helps,
