Hi. I have a custom Linux distro running where we (unfortunately...)
support telnet, using netkit-telnet-0.17.
A while ago, I upgraded util-linux from 2.20.1 to 2.22-rc2 (to get
sulogin, since I switched to systemd). One side-effect of this, which
I didn't catch for some time (not frequently using telnet), was that
telnet started chopping some characters off its output. The changes
appear to be related to login(1).
========================================================

========================================================
(The hostname was supposed to be 'hgbsaturn'.)
The tcpdump capture of the session is attached.
Has anyone seen anything like this? I tried to look at the changes in
login between the two versions, but they were too many. We did use
PAM before too, btw.
