I am trying to mount a samba server using mount -t cifs -o username=x,password=x //foo.com/username /home/lesshaste/work and I get Send error in SETFSUnixInfo = -5 CIFS VFS: Negotiating Unix capabilities with the server failed. Consider mounting with the Unix Extensions disabled, if problems are found, by specifying the nounix mount option. If I then mount with nounix I don't seem to be able to overwrite existing files but strangely I can delete them. This makes editing a file very difficult, for example. Any ideas what is going on? The client is on ubuntu jaunty 9.04. I have attached a compressed (and slightly anonymised) version of the logs for the mount operation above. Raphael
