Do you have permissions to execute it? Try chmod 755 /usr/local/bin/ck_internet

chmod 755 /usr/local/bin/ck_internet Is there a wy to put this in the permissions.local file? I had entered it in

Just putting it in that file doesn't do anything by itself. If you want it to take effect you need to run "SuSEconfig --module permissions", and/or run the chmod command manually
...unless I specified the user.group incorrectly, or something. I had: /usr/local/ck_internet root.dialout 755 ...I then tried 6754
First of all, the suid and sgid bits aren't used at all for shell scripts, so if you want to run this script you will either need to run it as root, or have the binaries it runs (cinternet) have the proper permissions. It is a client/server thing, that calls the smpppd server, so I don't think you need it to be root/dialout at all. Secondly, if it had been a binary, and you had needed the suid, the permissions are a little inconsistent. the '6' at the start means 'suid + sgid', but the '4' at the end doesn't give you permission to execute the program unless you are already either root or in the dialout group, so 4750 is probably what you're looking for. I believe that is the default for pppd, to allow dialout only to those in the group 'dialout' 6755, if you absolutely must be in the group as well, and want to allow execute access to people who aren't. But like I said, for shell scripts suid and sgid aren't used at all, so the above is a little academic :)

If I understand your error correctly it looks to me like you don't have either the correct user permissions on the script or you don't have the execute bits set. Check the ownership of the script and the permission bits. One of those is not correct. -- Scot L. Harris <webid@cfl.rr.com>

I would check the perms and make sure that the script is executable, i.e. -rwxr-xr-x perms would make it excutable for anyone. Change to suite your needs. Ken
