The Samba-Bugzilla – Bug 426
error: SMB signing is mandatory and we have disabled it
Last modified: 2005-11-14 09:28:42 UTC
I have a Windows 2003 Server (named volcano) which I am attempting to mount a
share from. My client is an x86 Red Hat Linux 9.0 box running Samba 3.0RC3
after a fresh reboot.
I issue the following command which is a command that worked fine before.
smbmount //volcano/c$ /mnt/volcano/c -o credentials=/root/smb.pass
(username and domain name omitted)
Instead of mounting the share, I receive the following error:
cli_negprot: SMB signing is mandatory and we have disabled it.
2639: protocol negotiation failed
SMB connection failed
I can't seem to find this error listed anywhere. If SMB Signing is
unsupported or something weird like that, could someone please point me in the
direction of how to turn it off?
smbfs does not support SMB signing. Your only option is to use
the newer cifsvfs file system. See
or you can disable smb signing on the 2003 server.
originally reported against one of the 3.0.0rc[1-4] releases.
Cleaning up non-production versions.
