I got a 2nd generation (I think, "Darwin appletv 8.8.2 Darwin Kernel Version 8.8.2: Mon Jan 29 18:57:29 PST 2007; root:xnu-792.94.18~1/RELEASE_I386 i386 i386") ATV device that in reality I use as network drive (and torrent machine).
Up until recently I was able to map it as network drive from Windows 7, Ubuntu & Android.
A few weeks ago (not sure when exactly), the mapping just stopped working.
I did not made any change - didn't even ssh into it for a long time.

Tried checking the configuration as per Enable SAMBA server - AwkwardTV - everything was already there.

I'm lost.
Any hints? If more info is needed, please let me know and I'll try to provide.

Note:
Could this be related to space?
bash-2.05b# df -a -h
Filesystem Size Used Avail Capacity Mounted on
/dev/disk0s3 900M 900M 0B 100% /

<volfs> 512K 512K 0B 100% /.vol
/dev/disk0s4 148G 130G 17G 88% /mnt

Which files on / are safe to delete?

Thanks,
