Hello,
I believe I may have found a minor bug in the "who" utility.
I am running RedHat Linux 7.3 on an i686 with kernel version 2.4.18-18.7.x
and version 2.0.11 of who.
The attached file, "whofile.txt", has output from the following commands:
1. who --version
2. who
3. ifconfig
4. who (after logout and login)
Note that the first "who" contains an IP address for the console tty1. This
should not happen. After logout and login, the second "who" does NOT show
an IP address for tty1. I believe that this problem is somehow related to
the fact that, for the first "who" listing, there is a LAN login with the
same timestamp as the console tty login. The IP address of this LAN login
is what is being displayed as the incorrect IP address of the console tty.
Perhaps a table is being referenced incorrectly, based on login time. (Note
that the IP address of the console is not one of the addresses shown).
Thank you.
