A simple shell script should be able to do your job, mutt is the my favourite for reading mails, the skeleton of the script is as follows.

su user1 -c "mutt" su user1 -c "mutt"

mutt is not at all what I have in mind!

I know you can su to a different user and use a text based mail reader like mutt or pine from within the xterm. I am looking for a full GUI mail reader that can be launched from the command line of xterm. Something that has the look and functionality of Netscape mail. I know there is Kmial but how can that be launched as a su'ed user?

To be more clear, if I have users root, joe, frank and bill. I log in as bill, su to root. Now su to joe and frank does not require a password. So I want to su to joe or frank and launch the equivalent of Netscape Mail / Kmail or whatever on bills desktop but as joe or frank.

I used to do this with XFmail in Red Hat 6.0 but I am looking for even more GUI functionality that even XFmail.

try: kdesu -u (joe_or_frank) kmail (or whatever) ain

What am I missing here?

Before issuing a 'su', try: xhost +localhost Then, after you got Super-User priviledges and assuming you use bash: export DISPLAY=:0.0 And then launch the graphical application you want.. HTH, Martin

libros:/opt/kde3/bin # ./kdesu -u adc kmail Xlib: connection to ":0.0" refused by server Xlib: No protocol specified

kdesu: cannot connect to X server :0

I know it some entry in some X config file but I cant remember. I can not even launch kde apps from the same user from a xterm.

libros:~ # /opt/kde3/bin/konqueror Xlib: connection to ":0.0" refused by server Xlib: No protocol specified

konqueror: cannot connect to X server :0

As as been discussed many time recently on this list, the above option is to be considered very unsafe and insecure. see archives.... --

A better method is to use sux to run the command, or you can setup an icon on your desktop and use the parameter to "run as" root which will prompt you for root's password. If you need to run "X" programs from a different machine on your desktop (remote administration) you will need to use xhost +<machine name or IP> before running the command and then xhost - right after. If there is a better way to do remote "X" admin work I would like to know. Be careful as it will allow others to "display" x programs on your display as well if you are not careful. It all depends on how secure your environment is. -- Ken Schneider unix user since 1989 linux user since 1994 SuSE user since 1998 (5.2)

This is exactly what I was looking for. I know about the security issues but all the users on the machine are me. I trust myself. The machine is set up with full firewall to the Internet. When I log on I am not worried about security between users because like I just stated all users are me. However, possibly due to the firewall I am still having problems. libros:/home/adc # xhost +localhost Xlib: connection to ":0.0" refused by server Xlib: No protocol specified xhost: unable to open display ":0.0" Same thing happens with xhost +"hostname" and xhost +IP ADDRESS Can anyone help? john ------------------------------------ John N.

I have not read all the posts, but I use Sylpheed Claws. One of the main reason I switched is that it fully supports MH folders. While Evolution does this, my folders have been around for years, and it would have taken me a long time to set them up under evolution which was my first choice. -- Jerry Feldman Boston Linux and Unix user group http://www.blu.org PGP key id:C5061EA9 PGP Key fingerprint:053C 73EC 3AC1 5C44 3E14 9245 FB00 3ED5 C506 1EA9
