[sudo-users] Understanding why processes launched by sudo do not inherit the controlling terminal

Todd,

Interesting. That reports the tty I expect to see.

So, I then tried:

   su jseymour -c "ps -u jseymour"

and this gave a broken result on the broken machine and a good result
on the other machines.

In other words, it has nothing to do with sudo at all - it's su
behaviour. Mmm. How strange.

Thanks very much for suggestion that, since it has got me a lot closer
to understanding the issue. If you have any ideas about what to look
at next, I'd certainly love to hear them!

jon.
