From Bugzilla Helper: User-Agent: Mozilla/5.0 Galeon/1.2.6 (X11; Linux i686; U;) Gecko/20020830 Description of problem: If a user is set to tcsh as their default shell, and they start a vnc session, and then within the vnc session use vim, within vim the backspace doesn't work, and instead yeilds "^?". The delete key does however work. Out side of vim, backspace works perfectly fine. It works in netscape, the command line, whatever. Its just within vim that it doesn't work. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Set an account to have tcsh as their default shell 2. log in to that account, and start a vnc session 3. use vncviewer to view that session 4. start vim 5. hit the backspace key Actual Results: hitting the backspace key outputs ^? to the screen. Hitting the delete key (which should be ^?) actually works correctly - it deletes characters to the right. Expected Results: hitting the delete key should delete the character to the left, not give a ^? Additional info: This problem occurs in all the systems here that are running the 7.x series. I have tried server things, and don't have a clue why it is behaving this way. This *only* happens with the combination of tcsh as the default shell, and then using vi within a vncsession. vi from a ssh sheell works fine. In fact, if 2 servers are set up the same, and a person has the problem on either server, if they simply log in to one server and start a vncsession there, then log in to the vnc session and within that vncsession ssh over to the other server, on the other server vim will work fine. This works either direction (start on 1, go to 2, start on 2, go to 1).

"I have tried server things" should have been typed "I have tried several things." It was just a typo. Those "things" mostly consisted of installing various versions of vim, starting people out in bash and then using "exec tcsh" in their bashrc. Also, an update...somehow one of the developers has accomplished making bash behave improperly as well (I changed him from tcsh to bash due to this problem, and he was workign fine until recently). I'm open to hear any suggestions.

added the vnc maintainer to CC: Tim, do you have an idea what's going on here ?
Comment 3 Tim Waugh 2002-11-04 14:21:46 UTC
VNC doesn't really support proper keyboard layout configuration, due to the way its protocol works. The best thing is to make sure that the keyboard layout on the local machine (where the viewer is) matches that at the remote machine (where the server is). I don't see that behaviour on the machine I just tried (Red Hat Linux 8.0); perhaps it's a bug that has since been fixed?

so the only solution is to change all my servers to RH 8.0? That doesn't work especially well... I just tried it on an 8.0 box, and you're right that it is ok there. However, its not ok on 7.0-7.3, and I don't think you'll find most of the user base for linux in server applications is at 8.0 just quite yet. I'm not entirely sure how it could be a keyboard issue, as they all work perfectly fine unless someone with tcsh as their default shell tries to use vi in a vnc session. If the person using tcsh in vnc does anything else, backspace works perfectly fine. And if the person starts a vnc session on one server, ssh's over to a different server, and starts vi there, it works fine. Its when they use vi on the server that is actually running the vnc session their using, and if they're default shell is tcsh, that there is a problem. Change those things in any way, and it works fine. Are there not any other suggestions I could try? I have 7.0 boxes here still, and until recetly still had a 6.2 box. Going through the trouble of going to a different "version" when all the versions are are collections of tools (that get updated seperately) seems a bit overkill to fix a backspace issue...

Does it work as expected when you call 'stty erase ^H' before you start vi ?
