For some reason I can no longer mount CIFS shares on my NAS (Netgear ReadyNAS) from my ubuntu box.

This used to work and only recently stopped. I can still connect fine using smbclient but using mount with either CIFS or SMBFS fails.

The odd thing is that it never actually 'fails', if attempt to mount I never get an error code back, just nothing happens - currently my mount command has yet to return to the command line and it's been like that for over 12 hours!

I can't see anything in any logs that would point to an issue.

If I put in the wrong credentials I got a bad password response, so it's definitely making contact with the NAS/share.

I can connect to the shares from my windows pc still

Anyone got any ideas?
