I just installed a linux SuSE-6.2 distribution with xemacs-20.4.

Starting gnuserv with M-x gnuserv-start doesn't work for a normal

user, only for root. It's the same with xemacs-21.1.

If I start <xemacs-directory>/i686-pc-linux/gnuserv from the

commandline, I get the message

/usr/local/lib/xemacs-21.1.6/i686-pc-linux/gnuserv: Permission denied
/usr/local/lib/xemacs-21.1.6/i686-pc-linux/gnuserv: unable to bind socket

My question now is: is it possible that either unix or internet

domain sockets are not available to normal users due to some

wrong configuration? I have figured out, that root creates a directory

/tmp/gsrvdirNN during the gnuserv-startup, normal users don't even do

that.

Any answer would be appreciated,

thanks

Jens

it's me again. I tried gnuserv with a test user (userid = 500) and
gnuserv-start worked perfectly well!!!!
So, large uids don't work small ones do. Could somebody explain this.
Can the behaviour be patched or is this a feature?

Jens

The default port used is

21490+uid

I really don't know a good solution for this. You need to set the port
explicitly, by setting the GNU_PORT environment variable.

thanks for your help. I first considered to change all the UIDs to low
numbers (it a new machine with only a few local users) and to map the
local UIDs to the ones in the NFS directories via the nfsd. Hm, was a
nice idea, but the NFS server is an AIX machine where UID-mapping
seems not to be possible (anyway the sysad there is no very
cooperative).
The second idea that we use now is simply setting GNU_PORT in
/etc/profile to reasonable values by something like
GNU_PORT=$UID-43000+21490 (if $UID > 44000). This leaves space for the
usual low number UIDs (like e.g. root).

Thanks again,

Jens

        $ gnuclient trash/foo
        gnuclient: No such file or directory
        gnuclient: unable to connect to local

This is with Xemacs-20.3 on Sun Solaris 2.5.1.

Does anyone have any ideas?  Interestingly everything works just fine
with GNU emacs-20.4 and the old server-start/emacsclient pair (why did
they have to fix what wasn't broken :(

TIA for any help :)

Try running gnuclient under truss to see where the problem is.
