Permissions Error

[jovisuk]

Hi Guys,

Back on the RSync backup, have just started to setup the CRON job to run it automatically, but am getting the following issue:

I've created the backup script which is:

GNU nano 2.2.4 File: backup-script

#!/bin/sh

rsync -av -e "ssh -i /home/backup-user/cron/backup-bubba-rsync-key" main-user@main-bubba:/home/
/home/backup-user/backup/

The result of which is below - it's saying that permission is denied on the folder /home/backup-user/backup on the backup-bubba - even though previous to this I have run a test backup to the folder which worked?

The active permissions are:

backup-user@backup-bubba:~$ ls -l
total 20
drwxrwxrwx 4 backup-user users 4096 Nov 5 19:57 backup
drwxrwxrwx 2 backup-user users 4096 Nov 9 12:15 cron

drwx------ 2 backup-user users 4096 Sep 13 11:47 torrents
backup-user@backup-bubba:~$

You are entering the systems as a particular user that does not have rights to the entire system. If that is what you want than you need to enter as root, which brings all kinds of security issues. It's not impossible to do safely though. Use this recipe:http://www.howtoforge.com/mirroring_with_rsync

Ok, so got round to working on this, and guess what - more issues . . . .

So when trying to edit the .ssh/authorized_key file I can't, I'm doing:

vi /home/USERNAME/.ssh/authorized_keys

Brings up a new screen and nothing responds, cannot type anything and cannot exit without crashing out the session - is there another way of editing the file and adding in the code?

Also, another issue is that on my main-bubba I have created the custom file structure with custom permissions to the folder /home/COMPANY so that now when I test a backup, the backup-bubba fails to back anything up in this directory as it has no permissions to the folder. Can I add backup-user as an authorised user to that folder on the main-bubba, even though the user account is from another bubba unit?

Am I making sense and can what I'm asking for be done?

You should not use vi if you do not know how vi works. vi I very powerful but also extremely hard to use for a beginner. I would say that it is impossible to use it without reading an manual on how to use it first. One of the reason people says you should use vi is because thats the only editing program that you can be sure exist in all Linux/Unix system.

I suggest that you install nano and use that program instead. Remember that the following command needs to be run by root.

Code: Select all

apt-get install nano

[Ubi]

and the answer to exit from vi is: pres the escape key, and then

Code: Select all

wq

to save data. or press escape and then

Code: Select all

q!

to exit without saving. Press escape and then

Code: Select all

i

to go into editing mode. But nano is probably easier to use. I always use joe as an editor.

[RandomUsername]

Pretty sure nano was pre-installed on my B2.

[jovisuk]

Thanks for the replies, I have tried nano - I tried it before using vi as I wasn't sure how vi worked (Curiosity got the better of me so I tried vi)

I should have mentioned that when I tried:

nano authorized_keys

The file opens up but appears empty??? Unless it's not empty and the file contents are hidden???

[Ubi]

or it means you're in the wrong place. try nano autho and press TAB before pressing enter. If the file exists then the shell will add the remaining letters (also known as tab completion). It's a good safeguard against typos too

[jovisuk]

Cheers again Ubi - SOLVED.

nano auth (then pressing TAB) solved it

Hi Again,

Been running this and checked the backup-script

But it says it has access denied to the destination for the backup files, which is:

/home/backup-user/backup

The backup-script is:

rsync -av -e "ssh -i /home/backup-user/cron/backup-Bubba-rsync-key" main-user@main-Bubba:/home/ /home/backup-user/backup/

Any ideas?

[jovisuk]

This is the end result after trying to run the backup script:

sent 199 bytes received 33784 bytes 3577.16 bytes/sec
total size is 629017573 speedup is 18509.77
./backup-script: 4: /home/backup-user/backup/: Permission denied
backup-user@backup-bubba:~/cron$

[Ubi]

You're asking the same question again. I'd be polite to read answers to your questions before asking more

[jovisuk]

Hi, thanks for the response - but you don't understand:

My question has not been answered, the initial problem was that I was getting Permission Denied, I then worked on it and couldn't edit the Authorized_keys file and then was able to after your help (thanks) - hence me saying SOLVED for that part (Granted this could have been confusing) but my problem still remains, I don't understand why I am getting permission denied on the /home/backup-user/backup directory when running the script?

Thanks again

[ryz]

So which user is running the cron job? That is how have you set up the cron job?

[jovisuk]

Hi, I did it all on the backup-bubba logged in as backup-user

That's why I cannot understand why it says "Permission Denied"

Is it worth starting again and creating a new cron job??
