Topic: smeserver-backuppc.fws bug? Cannot access the web page.

[iltasu]

Hello, some times ago, I've installed this contrib, it worked really well for a long time, but now (probably after the upgrade to sme 7.3, I can no more access the management page in server-manager, it asks for a username and password via the browser dialog, not relaying on the new php base mechanism, and after that it stays forever loading the page, it never manages to show me the admin page anymore, what could it be? is this a bug? Can I provide more informations in order to find a solution? (being without a backup makes me a bit worried!)

Yes, some more info could help. I run this contrib on about 20 servers without problem, even with latest updates. Can you access the admin page with the url https://yourserver/backuppc (outside of the server-manager).
You should check the logs of apache:

Code: [Select]

tailf /var/log/httpd/error_log
You can also check the permissions on the cgi:

Code: [Select]

ll /opt/backuppc/cgi-bin/
-rwsr-x---  1 backuppc www 3993 avr 26  2007 BackupPC_Admin

Thanks for the prompt answer! ^_^

I cannot access https://servername/backuppc (that redirects to: https://192.168.131.3/backuppc/cgi-bin/BackupPC_Admin), after asking for username and password, it waits for a long time on a white page then it answers with this error:

Code: [Select]

(The BackupPC_Admin part of the previuos string is red colored, don't know what it means!)

Thanks again! ^_^

These error in apache logs are strange. Anyway, this line:

Code: [Select]

AuthExtern pwauth [/usr/lib/httpd/modules/pwauth]: Failed (1) for user admin, referer: https://192.168.131.3/backuppc/

Seems to indicates that your not entering the right password for admin user. Have you tried with a standard user?

I don't know where the problem comes from, but you can try to remove the contrib and install it again, it should keep all your configuration (and of course your data)

[iltasu]

Ok, tried both the admin user and a normal user, both lead to the same result: white page then the error.
Already tried to uninstall the contrib and reinstall it... to make the cleanest things I can, I uninstalled the rpm, unmounted the /opt/backuppc (it's mounted via a nfs share), reinstalled backuppc, stopped via init.d the service, re-mounted the network share, then restarted the service.

[Daniel B.]

Ok, maybe the problem comes from the nfs share (I never tried backuppc on nfs), so maybe you can try the following:

- uninstall the contrib
- un-mount the share
- install the contrib locally (without anything mounted on /opt/backuppc)
- test if it works

[iltasu]

Indeed it works, but I used this network share for more than one year.. I can't understand what's changed... (And I cannot copy the backups to the same disk where the sme server is installed, I have not enough space there for both datas and backups... and I don't feel ok sharing the same disk between actual datas and backups).
