chmod -rw-rw-rw- to srw-rw-rw-
The question is simple.
I have these to files:
-rw-rw-rw- 1 popuser root 0 Nov 18 11:26 spamd_full.sock
-rw-rw-rw- 1 popuser root 0 Nov 18 11:26 spamd_light.sock
and I want to change them with the permissions like these 2:
srw-rw-rw- 1 popuser root 0 Aug 22 11:29 spamd_full.sock
srw-rw-rw- 1 popuser root 0 Aug 22 11:29 spamd_light.sock
so I did chmod 666 spamd_*
but the problem is how do I give the "s" before "rw" ?

To change the filse permission from
-rw-rw-rw- 1 popuser root 0 Nov 18 11:26 aa
to
-srw-rw-rw- 1 popuser root 0 Nov 18 11:26 aa
to need to do:
chmod u+x aa
chmod u+s aa
where aa is the filename
man chmod
to learn more details.
Please note that there is security risk for script to use suid, please read the following docs to learn

I assume MaRiOsGR wants to suid to the owner/user.
It is dangerous to have a file suid and it is world read/writable, some one can modify the script
to do whatever to the system!!!

Rather if it will overwrite the script with some binary. Scripts are not affected by suid bit, but You surely can
cat /bin/bash > /path/to/suid/scipt

MaRiOsGR:
The first letter in the permissions display indicates what type of file it is - what you are asking is how to make a socket (that's what the "s" stands for). The "s" in any other position than the first would indicate a permissions issue and I believe all the experts above have addressed that. But if you <really> want to create a socket, that's accomplished programmatically... and you should consider posting your question in one of the programming forums.

Oh, BTW, the socket will be removed when the system is normally closed
by spamd.
by spamd.
Please explain what You want?
to set suid bit: chmod +s spamd_* # use -s to remove
to set sgid bit: chmod +S spamd_*
to set sticky bit: chmod +t spamd_*
