Hi all,
I am unable to schedule a GUI application to run using a cron job.
I am using RedHat Linux 8.0. below is my crontab
<<crontab>>
SHELL=/bin/bash
HOME=/home/pradeep
10 2 * * * root /usr/X11R6/bin/xcalc
<<crontab>>
It gives me an error message that " cron : Unable to connect to X
Server"
Is it possible to do this? If so, help me out in doing this. Thank you
all in advance..
Thanks,
Pradeep

Subject: NIS and NFS
Hi all, I've been wrecking my brains over this one but I'm threading
water:
I have a Linux-only network with one server and a number of stations.
The
server's /home directory is exported and mounted by the stations via
NFS. The
server also serves NIS and the setup lets users log onto any one of the
stations and have the same /home/~user everywhere.
My problem is that every user is 'root' at his/her own station. Of
course NFS
has been configured not to grant access to remote root users, but
there's
nothing to prevent users from 'becoming' someone else with su and then
the
NFS/NIS authentication scheme falls flat on its face.
For instance:
. User 'jdoe' logs onto his own station. He's authenticated via NIS and
mounts
/home from the server.
. jdoe then runs 'su' and becomes root.
. root runs 'su - jblow' and becomes jblow.
. jblow cds to /home/jblow...
After going through man docs, howtos and google entries for NIS, NFS and
su and
drawing a blank, I'd appreciate any and all insights you people may have
on
the subject.
TIA,

Try specifying the "-display" parameter, and make sure that the
permissions on your Xserver are configured properly.
I.e.

Why did you put "sh" in there? Per the error message, 'sh' can not
execute the xcalc binary.
Further, aa.bb.cc.dd needs to be replaced by the ip address of your X
display server (or 127.0.0.1 if local). I.e.

Alas..
I did a big mistake by putting the 'sh' . Yes yes I replaced aa.bb.cc.dd
with the actual IP address,
but just for example I mentioned it in that way in my previous mail.
Anyhow, thanks a lot ..your response helped me a lot..
Thanks again..
