rush config errors: not an absolute directory name

  • 772

Migrating from rssh to rush...

I can't figure out what it means by not an absolute directory name. see logs below:

Aug 31 14:07:24 secmgrprd04 rush[3904968]: errors parsing config file

I actually copied the example from the documentation which had chroot "~" and I changed it to an absolute path and still got the same error.

Ubuntu 20.04, installed by apt, Version: 1.8+dfsg-1.1

baffled!

  1. From documentation:

       chroot <DIR>
          Change the root directory to DIR.  This directory  will  be  used  for  file  names
          beginning  with  /.   A  tilde at the start of DIR is replaced with the user's home
          directory.

   chdir <DIR>
          Change to the directory DIR.  The argument is  subject  to  tilde-expansion  as  in
          chroot,  above.   If  both  chdir and chroot are specified, then chroot is executed
          first.

    Now I guess either dir is not exists or permissions are missing. To check which parameter causing issue add debug 3 line to your config.
