Description of problem:
The ntalkd protocol allows a max user name of 12 chars long. (At least
newer) RH allow more than that, rendering ntalk[d] useless for users
with names > 12chars. I guess changing the protocol to allow longer
user names makes it incompatible to previous ntalk[d] releases.
Possibly a reason to remove ntalk[d] from future releases?
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. $ useradd a_long_user_name
2. $ ssh -l a_long_user_name localhost
3. talk a_long_user_name@loclahost
Actual Results: "User is not logged on"
I don't consider this to be a crucial bug if at all as the protocol
simply doesn't allow more than 12 chars for a username doesn't mean
that therefore usernames with longer characters have to be forbidden.
Additionally talk has not been of outmost importance over the last few
years and is simply provided as is.
So i'm closing this bug as wontfix as i can't fix the protocol (which
would break it for interaction with any other Unix) nor can we
disallow usernames with more than 12 chars.
Read ya, Phil
