Backup over ssh : Permission denied

[DiQ]

Using nssbackup_0.2-0~rc8 on karmic which includes a fix for Question 96168 (https://answers.launchpad.net/nssbackup/+question/96168).

When I click Test on ssh://USER:PASSWORD@SERVER:NNNNN/PATH I get "Test Succeeded !"

However when I try and backup I get a box appear with:

NSSBackup [Default Profile]
An error occured: '[Errno 13] Permission denied: '/mnt/nssbackup/ssh_USER@SERVER_NNNNN/PATH''

Log gives me :

2010-01-24 15:54:19,828 - ERROR - nssbackupd.py:__onError(226) - [Errno 13] Permission denied: '/mnt/nssbackup/ssh_USER@SERVER_NNNNN/PATH'

    mkdir(name, mode)
OSError: [Errno 13] Permission denied: '/mnt/nssbackup/ssh_USER@SERVER_NNNNN/PATH'

No backup is made, and so this prevents me from using NSSBackup

Have just tried this on a different machine and it's not a problem when using port 22, only when using other ports

[Oumar Aziz OUATTARA (wattazoum)]

Hum ! This is a very useful information, I will try testing this home.

[DiQ (dik23)]

I have also discovered that if you enter ssh://user:password@server/path there is no problem

However if you enter ssh://user:password@server:22/path there is a problem

It is the :NNNNN that is causing the issue whatever the port number

[DiQ (dik23)]

I have also noticed that there's a problem running the program from the SYSTEM > ADMIN menu, but this maybe another bug

[Oumar Aziz OUATTARA (wattazoum)]

I have succeeded reproducing the problem. this happens only when using root (admin account).

[DiQ (dik23)]

After this error happens it seems impossible to open NSSBackup as root again, even after a "complete removal" and re-install using Synaptic.

[Oumar Aziz OUATTARA (wattazoum)]

can you try using on a shell:

sudo nssbackup-config-gui

You should see some information print and the cause of the error should be part of it.

[DiQ (dik23)]

Ok - give me a little bit. I have already done this and recorded the result but before I could post here the machine I was testing on has had it's graphics card fail. I will set up another later on today and get back to you

[DiQ (dik23)]

Here you go :

[DiQ (dik23)]

I did a Synaptic "complete removal" including the following that are installed along with NSSBackup :

curlftpfs
python-pexpect
sshfs

When re-installed NSSBackup still won't run and gives an identical error as above.

[DiQ (dik23)]

I am now testing using a persistent USB install and so can get back to having NSSBackup installed and working by replacing the casper-rw file with one that I'd backed up.

The above problem only happens after I move the log file (under Report) to my desktop from /var/log/

I had done this to make the log easier to view and am not sure if this is a bug

[DiQ (dik23)]

Actually maybe it's not moving the log location - maybe it is setting it to "error" that is the problem

[Oumar Aziz OUATTARA (wattazoum)]

I confirm that it is setting the log level to ERROR that creates the problem. When loading the nssbackup config window, the key "40" is not found at one point.

[Oumar Aziz OUATTARA (wattazoum)]

Can you try with this one? The UI should start now.

[DiQ (dik23)]

does this solve the ssh problem too ?

[Oumar Aziz OUATTARA (wattazoum)]

no, I am still trying to find the ssh problem cause out.

[DiQ (dik23)]

The GUI now starts with log set to error

It also starts with all of the other log levels

[Oumar Aziz OUATTARA (wattazoum)]

This one should solve the SSH problem. Can you test it ? I hope that it works :-)

[DiQ (dik23)]

Yep, all works !

Thanks for sorting that out, you're a star

If I have any questions or find any bugs I'll get straight back to you ;0)

[DiQ (dik23)]

Oh - in answer to your previous question - on of the things I'd like to see in v0.3 is the ability to restore more than one folder at a time.

Also it would be nice to be able to return to an inc backup point without having to start at a ful and make the way through all of the preceding incs.

Just an idea

Yes, I second that. In fact, I'd propose a restore browser that shows
your complete filespace, and shows which backups there are for each
file. Default restore would be the latest, from whichever set it comes.
