Description Ted Kaczmarek 2003-12-07 17:57:42 EST

Description of problem:
Zebra daemon vtysh access from bash, shell will freak out. Issuing
reset corrects the problem.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.Fire up zebra daemon
2.vtysh, en, wr t
3.exit vtysh, hit enter 3 times

Actual Results:  tarkus# exit
[root@tarkus root]# [root@tarkus root]# [root@tarkus root]#
[root@tarkus root]#

Expected Results:  [root@tarkus root]#
[root@tarkus root]#
[root@tarkus root]#
[root@tarkus root]#

Additional info:

Zsh does not exhibit this behavior, so it could be classified as a
workaround :-) 
[root@tarkus root]# cat /etc/sysconfig/i18n
[root@tarkus root]#

That will be a bug in vtysh, not bash.
Comment 2 Ted Kaczmarek 2003-12-13 16:27:38 EST
This problem occurs with ssh also, after connecting to a RH9 box via
ssh, I get the same quirks where the shell has to be reset. It appears
that some signals get messed up, reseting the shell will also fix
every time. Again with zsh I do not see the problem.
Comment 3 Tim Waugh 2003-12-13 18:23:33 EST
'Some signals get messed up'?  It is a signal handling problem in the
*application*, yes, in that it doesn't return the terminal to the mode
it found it in.
