[system is not compromised (i.e. security issue) it is broken - mod]
Hi everyone, i hope someone can spend his time to try help me.
its been more than 6 months since the system started running fine, never had problem and everything was fine, in/out coming calls, queues and so on…
Yesterday morning i wake up and it was not possible anymore to take incoming calls from the outside (internal and outgoing was fine)
I disabled the firewall, restarted it, nothing changed, so i tried to do a Restore.
and from there the system got compromised!
I dont know how the hell the restore failed, it says its corrupted with some errors, but months ago i tested the backup and it used to works fine!
Now, i tried to do a whole new installation, running an older backup, the system felt like was fine but it actually missed a file or someting! i did a /reboot form my machine and this happens
any idea on what to do? any idea on why the latest backup got corrupted randomly?
im so in troubles since now my company is without comunications, hope someone can help, thanks for your time!
thats the problem… how can i be sure that the backup and the new system have the same version?
i think they are both 14
yes, i can SSH into the pbx if needed

nonono, i need to do a restore, but it doesnt works!
if i go with restore, it get compromised and doesnt work
but it should, it definitly should because im sure that, months ago, i tested the backupfiles and they used to work!
i just setup the FTP server from the backup &restore module
select the back up zip file, select all the files except CDRs, click “Go!”
btw, on the new installation i did a backup just to see if the path war right… well, it did the backup, so then i used the older one from 6 months ago, the system got compromised as tyou can see belove, AND THE BACKUP OF THE LAST NEW INSTALLATION DISAPPEARED o.O
now the system is basically f.up and cant do anything except do another fresh intallation…
im worried i will have to start from zero and do all the settings and operations i did months ago…
This has been a problem for at least as long as I’ve been using Asterisk@Home and AMP. One of the selling points, and a huge amount of the expense in creating Asterisk 15, was to solve this known specific problem. You can’t restore from a different version to a FreePBX installation before Asterisk 15. I’ve heard the legends of people using the backup and restore module, but when I’ve tried, it’s consistently failed. I’ve never been able to get all of the specific modules to work - there’s always one that screws up the reinstall. Moving it from one machine to another has also always been consistently disastrous. The new one in Asterisk 15 works (from what we’re hearing) for the first time that I know of.
If that’s true, you could try installing Asterisk 15 on your server, restore the Version 14 backup, and let us know if that worked.
this is a heking big problem… gonna do a whole new installation and making a guide for myself so the next time i’m in trouble i can just reinstall everything and its gonna be fine…
BTW i discovered all the problems started by the external telephones lines, it had nothing to do with my PBX … so basically i fuked up everything tryng to restore and it was worthless XD
I’ve never looked at the backup files, but if you’re a reasonably adept Unix Guru, you can probably unpack them and look at them. I’d guess that they are mysqldump files, which are nothing more than a series of MySQL scripts that put data back into databases. You probably can’t use the database data directly, but at least you can get the information.
A ‘full’ backup has two mysql dumps, one for asterisk mysql-3.sql one for asteriskcdrdb, mysql-4.sqlb, you can ‘read’ them into mysql to regenerate the mysql state.
There is also a copy of the sqlite3 database that gets put into /var/lib/asterisk/astdb.sqlite3
There are also copies of asterisk related files in /var/www/html/ , /var/lib/asterisk and /var/spool/asterisk and /etc/asterisk.
Unless you have trashed your filesystem , then restoring the three databases is all you need to restore your system
My system was hopelessly failing as well. Note sure if you introduced additional issues by trying to restore but my suggestion is to upgrade to the latest version of everything with CLI command
fwconsole ma updateall
yum update
This will update the system, to an unstable version but will allow you to downgrade to a stable version by running the following command
fwconsole reload
yum downgrade asterisk*
This should put you into the stable version 13.22
I’m sure there is an easier way to do this but I had 5 systems that became completely unstable after upgrades and this made them all stable!
