[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. ------- Additional Comments From dkl 05/25/99 19:38 ------- I have verified this bug to be true in 6.0. ------- Additional Comments From bob.ac.be 05/25/99 23:17 ------- this is a duplicate of bug# 2455.
Fixed in wu-ftpd-2.5.0-1.
Tested all archs 4.2, 5.2, 6.0 8 JUN 1999
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: --- wu-ftpd-2.5.0-clean/src/ftpcount.c Fri Jun 11 14:04:56 1999 +++ wu-ftpd-2.5.0/src/ftpcount.c Fri Jun 11 14:08:59 1999 @@ -229 +229 @@ - pidfd = open(pidfile, O_RDWR, 0644); + pidfd = open(pidfile, O_RDONLY, 0644);
