Local backup folder not found and perms not working on ssh

[dfmco]

I created the directory and set permissions as follows:
chmod u+rw /home/nagiosbackup/localbackup
chmod g+rw /home/nagiosbackup/localbackup
chown nagios:nagios /home/nagiosbackup/localbackup

But when I try to test permissions to that directory, Nagios says the directory does not exist. Is there an issue using sub-directories as if I go one level up, it does find the directory and it works.

For ssh permissions, do I use permissions for the remote user or set to nagios:nagios?

[lmiltchev]

Is this a local or SSH backup? You are talking about both... What is the output of the following commands?

Code: Select all

ls -lad /home
ls -la /home
ls -la /home/nagiosbackup

Is the "/home/nagiosbackup/localbackup" directory located on your Nagios XI server or on a remote box?

[dfmco]

I am having a problem with both local (saving locally) and ssh (saving remotely). Accounts are set up on both the local and remote servers with permissions set per the commands in the original post.

and here is the second server. Both have the same issue with the backups. I am doing ssh and local on each. Local backup is one copy and the ssh saves the backup to its partner.

I believe the issue is caused by the fact that the "/home/nagiosbackup" is not executable. Run:

Code: Select all

chmod +x /home/nagiosbackup

and test the permissions again. Did this help?

[dfmco]

Local works now but no luck on ssh. I did -R to recursively change permissions and that failed too. What permissions are needed on the target server for ssh? Should it be owned by nagios:nagios or the ssh id?

Does the user that you ssh in as own the "backup" directory? Here's an example of permissions of my "backup" directory on the remote box:

Code: Select all

root@debian:~# ls -lad /home/lmiltchev
drwxr-xr-x 3 lmiltchev lmiltchev 4096 Mar 29  2015 /home/lmiltchev

Here's a couple of screenshot from my test XI box:

Hope this helps.

That did the trick! I changed ownership for the remote directory to the ssh user and it is working now. Thanks!
