This question already has an answer here:

Is there a possibility to create a hard link for an unix socket? I'm creating a jail and symbolic links won't work, so I'm looking for a solution, how to provide an unix socket inside chrootted environment.

The only idea I'm coming across is to use something like netcat but is there any reliable possibility?

    I'm not sure why this is marked as a duplicate. The other question just asks about creating listening sockets in the filesystem, this one is about duplicating them. – Will Manley Jul 4 '17 at 8:09

    Agreed, if I had the rep I would be casting a reopen vote here. – Peter Green Oct 19 '17 at 14:35

Linux at least would allow you to use a bind mount to make either a directory or alternatively a single file available at multiple places. Not tested, but in theory it should work...

  mount -t bind /var/MySQL.sock /chroot/var/MySQL.sock 
  • Bind works only for directories, so it doesn't solve the problem. – eRIZ Apr 17 '14 at 20:26
  • In the words of the man page One can also remount a single file (on a single file), and I have no problems accessing the MySQL daemon through the socket in the bind mount. But I don't have any chroot set up to test more. – HBruijn Apr 18 '14 at 12:57
  • Parameter list consist on two directories. I mean mounting a link directly, without separated directory. Could you provide your command line I can test against? Is this the above you cited? I tried to make it happen but this doesn't work. – eRIZ Apr 18 '14 at 17:56
  • You can also put the socket in a directory created for this purpose, and bind mount that. – Falcon Momot Apr 18 '14 at 18:43
  • @FalconMomot, I know but I want to solve problem. I'm aware of a workaround. [; – eRIZ Apr 18 '14 at 21:55
