Hi,
in environments with Kerberos and especially NFS with Kerberos, it is
important to keep the Kerberos credentials valid by renewing them at
the proper time. Doubly so with screen or tmux sessions since they
typically run for a longer time.
There is the tool krenew which does this automatically
hi
why not just run krenew separately from tmux?

Hi Nicholas,
A few reasons:
- Cloning the credentials cache is important when you use ssh, because
ssh will delete the original credentials cache on logout. Cloning the
credentials cache is only possible when krenew is given a command to
execute.
- Because of the cloning krenew needs to change the

Yes, I'm sure. It is possible because krenew is the parent of the
"screen -Dm", so it can change its environment before forking.
$ echo $KRB5CCNAME
FILE:/tmp/krb5cc_11543_McyAWZ
$ krenew -- bash
$ echo $KRB5CCNAME
/tmp/krb5cc_11543_j2DI5W
Best,

If it changes the environment before forking, tmux should pick it up as
well.
You'll need to do something different to monitor for tmux exiting and
make krenew exit.

Yes, but this cloning the credentials cache and changing the
environment works only when giving a command to execute. When I give
"tmux new -d" as the command, krenew will immediately exit and remove
the cloned credentials cache, because tmux forks and exits. So this is
not a real solution.
I gues
