We had a new server put in on our local network and I am unable to mount it's file shares - mount -t smbfs works on the old server but it doesn't work on the new one because of the SMB signing problem. However, I cannot get mount -t cifs to work on either of them. Anyone have any ideas what the problem could be? Thx vperry successful commands: 1) smbstatus calserver01 2) smbstatus linuxa 3) net rpc user -S calserver01 -U ntuser%pass - lists all nt users 4) net rpc user -S linuxa -U linuxUser%pass - lists all linux users 5) sudo smbclient -L calserver01 -U ntuser%pass - lists the services on calserver01 6) sudo smbclient -L linuxa -U linuxUser%pass - lists the services on linuxA 7) sudo smbmount //server01/EasyPHP1-8 server01easyPHP -o username=ntuser,credentials=/etc/samba/user - successfully mounts easyPHP share on server01 8) sudo mount -t smbfs //server01/easyPHP1-8 server01easyPHP -o user=ntuser,credentials=/etc/samba/user - successfully mounts easyphp share on server01 failed commands: 1) sudo smbmount //calserver01/Corporate serverCorporate -o username=ntuser,credentials=/etc/samba/user cli_negprot: SMB signing is mandatory and we have disabled it. 10671: protocol negotiation failed SMB connection failed 2) sudo mount -t smbfs //calserver01/Corporate serverCorporate -o user=ntuser,credentials=/etc/samba/user cli_negprot: SMB signing is mandatory and we have disabled it. 25791: protocol negotiation failed SMB connection failed 3) sudo mount -t cifs //10.20.10.10/Corporate serverCorporate -o user=ntuser,credentials=/etc/samba/user mount error 13 = Permission denied Refer to the mount.cifs(8) manual page (e.g.man mount.cifs) 4) sudo mount -t cifs //calserver01/Corporate serverCorporate -o user=ntuser,credentials=/etc/samba/user mount error: could not find target server.
