Description Bert de Bruijn 1999-05-01 00:28:42 UTC
[root@sun /root]# ftpwho
Service class local:
    1 ?        S      0:03 init
   -   1 users ( 10 maximum)

Apparently ftpwho fails to grep for the right process.
As far as I can tell, ftpwho does select the right class for
ftp-users, but always gives process info for init, never for
an ftpd process.

(I observed this bug on sparc and i386)

Verfied on 6.0 intel system.

*** Bug 3042 has been marked as a duplicate of this bug. ***

The 'ftpwho' program uses 'ps' to list the process and then
show the 'ftpd' process.  The 'ftpwho' program doesn't
understand the new output format of 'ps', so it shows
meaningless process.

There is still a bug in ftpcount/ftpwho: they try to open the PID file
O_RDWR (read/write), even though they only read from it.  This means
that only root can use ftpcount/ftpwho (which is not a security
problem - they just gather and present available information).  This
one line change will fix that:
