Subject: ldm: Logged in users do not show up on 'who'

Date: Wed, 11 Jun 2008 16:17:16 +0200

Package:  ltsp-client
Version:  0.99debian11
Severity: important
Tags:     patch
User:     debian-edu@lists.debian.org

When a user log in using the ldm version in Etch, the /var/run/utmp
file isn't updated and the user fail to show up as logged in.  This
affect systems that check for logged in users, like the killer
package.

I found a solution, which is to add -t to the ssh argument list.  See
<URL:http://lists.debian.org/debian-edu/2008/06/msg00022.html> for
background information.

Looking at ldm version 2:2.0.6-1, I see that this is already done for
the C version of ldm.  Please do this for ldm in Etch too, as it
confuses syadmins and make it harder to know if a machine is unused or
not.

Here is a patch to solve it.

indeed, i can confirm it works fine in lenny and sid.

i wouldn't object to an upload for etch(presuming it was well tested, of
course), but don't have time to work on it myself.

Version: 2:2.0.6-1

since this is fixed in lenny, due to be release real soon, i think i'll
finally close those bug as an uploaded fix for etch isn't likely at this
point.

live well,
