Hello there,

Today I´m having this error when accesing web control page.

uuidgen: '/usr/lib/libuuid.so.1' is not an ELF file uuidgen: can't load library '

I have RC5 on DNS-323. It seems some corruption in firmware partition. Fortunatelly I've got telnet available.

How can I fix it?

Thank you in advance

Moises

What does 'ls -l /usr/lib/libuuid*' outputs? It should be

[root@DNS-325]# l /usr/lib/libuuid*
lrwxrwxrwx 1 root root 12 Oct 2 19:55 /usr/lib/libuuid.so -> libuuid.so.1
lrwxrwxrwx 1 root root 14 Oct 2 19:55 /usr/lib/libuuid.so.1 -> libuuid.so.1.2
-rwxr-xr-x 1 root root 14704 Oct 29 18:43 /usr/lib/libuuid.so.1.2

try running 'ldconfig' to fix it, showing as above.

Seems that libuuid.so.1.2 is empty (0 size)

I checked that several libraries are 0-sized. Probably when I uninstalled samba package, they got deleted....

How can I restore these libraries ?

Thank you.

That's a serious problem, that shouldn't happen in any way. There are several *essential* system libraries missing.

I'm not sure wherer the system will boot in that circumstances. If it is a flash memory issue, it will probably not, but if it is due to some error on some the disk-installed/upgraded packages, then booting without any disk installed will solve that (but the error on disk has to be fixed before).

It's difficult to recommend a course of action without having a precise diagnostic, as the box might not even reboot.

What does the following command 'ls -lS /Alt-F/usr/lib/lib*' outputs?

Probably when I uninstalled samba package,

How did you uninstall samba? Using the webUI? Using the command line 'ipkg' command? Removing files?

There are several samba packages, samba-small, which is on the base firmware on flash memory, can't be uninstalled, and on disk can be samba, samba-extra, samba-modules...

In any case, execute the following commands before rebooting and/or removing the disk:

aufs.sh -n # always do this before manipulating anything under the Alt-F folder
touch /Alt-F/NOAUFS # prevents the Alt-F folder to become active on the next boot (on RC5)
aufs.sh -r

Dear Joao,

these commands

aufs.sh -n # always do this before manipulating anything under the Alt-F folder
touch /Alt-F/NOAUFS # prevents the Alt-F folder to become active on the next boot (on RC5)
aufs.sh -r

worked perfectly. Now i have my system up and running again.

Thank you so much.

After doing this, I´ve lost installed packages (such as ethtool) which I need to avoid network corruption...

How to -re-install ipkg and other packages?

Can I reflash firware again?

Thank you.

Yes, of course, that was expected, disk-installable packages are installed on the Alt-F folder, and that was disabled.

The original issue occurred because some files under the Alt-F folder was "shadowing" the original ones copied at boot from flash to memory.

So, you can either fix the files in error (if you know how to do it) and reactivate the Alt-F folder, or reinstall the Alt-F packages. That is done under Packages->Alt-F.

(such as ethtool) which I need to avoid network corruption...

That is useless, the data/files in error are on disk (the Alt-F folder that you must *not* directly manipulate without special care), not on flash memory, so reflashing will not help.
