I have this directory:

drwxr-x--- 2 root adm 160 2011-08-18 02:13 apache2

Im belonging to the group adm but I can not access to the directory..It says: "Permission denied".

  • What is the entire path? if it's /home/apache2 you'll need 770 from /home on up. – NickW Jun 14 '13 at 15:30
  • it is /var/log/apache2 – user35538 Jun 14 '13 at 15:30
  • what are you trying to do to the directory? – NickW Jun 14 '13 at 15:32
  • I just want to print the apache log using "tail -f /var/log/apache2/error.log" – user35538 Jun 14 '13 at 15:32

    There you are then, it's the permissions on error.log. Try doing sudo ls -all or su'ing up to root – NickW Jun 14 '13 at 15:41

After you are added to a group, you will need to log out, then in again, or do an su - <yourusername> to get the system to recognize your new privileges.

Or you have a group created in an ldap back-end that has the same name as a group in /etc/group. Spottable with numeric group ids.

Hiding...

talcom@plato:/home/smb$ ls -lah /home/smb/
...
drwxrws---  2 root staff      4.0K Mar 17 19:43 scans
drwxrws--- 14 root staff      4.0K Mar 29 11:41 staff

Revealed! ...

talcom@plato:/home/smb$ ls -lahn /home/smb/
...
drwxrws---  2 0 5076 4.0K Mar 17 19:43 scans
drwxrws--- 14 0   50 4.0K Mar 29 11:41 staff

Also, if you're really silly and create duplicate group names in /etc/group, and you're only a member of one of the copies, then you can appear to be in the group when running the id command, but the directory may actually belong to the other group.

    I would definitely never edit the group file by hand, so I couldn't possibly have actually happened to me – Brad Mace Jan 18 '18 at 21:33
