Public bug reported:
The following command works:
mount -t cifs //192.168.1.200/Drive_E /mnt/server_e -o
credentials=/root/.smbcredentials_server
The following fstab entry fails:
//server/Server_E /mnt/server_e cifs
uid=0,credentials=/root/.smbcredentials_server,file_mode=0755,dir_mode=0755,vers=2.1,sec=ntlmssp
0 0
There is an entry in hosts for server. It also fails with
//192.168.1.200/Server_E
Sometimes it says:
No dialect specified on mount. Default has changed to a more secure dialect,
SMB2.1 or later (e.g. SMB3), from CIFS (SMB1). To use the less secure SMB1
dialect to access old servers which do not support SMB3 (or SMB2.1) specify
vers=1.0 on mount.
[ 2079.955734] CIFS VFS: BAD_NETWORK_NAME: \\192.168.1.200\Server_E
CIFS VFS: cifs_mount failed w/return code = -2
trying vers=1.0 and vers=3.0 makes no difference.
There is no documentations of CIFS VFS error codes
There is no documentation of how to specify the SMB dialect.
People appear to have been having trouble with these things for at least the
past 10 years.
I never had a problem with this on debian.
