Finding the mount equivalent for an smb: URL

Question

I'm running Lubuntu 16.04.1 on my laptop. At work, I plug it into the wall with an Ethernet cable. This provides Internet access and also lets me access a directory of files (perhaps a share, or is it a server, or both?) called cchfs (smb://cchfs), which is used as a mapped network drive on the Windows machines here. I can see the files in cchfs by opening PCManFM, choosing Go → Network, and then opening the icons "Windows Network", "NPI_HRRP", "CCHFS" (here I'm prompted for my login details), "Root".

This all works fine, but I'd like to be able to interact with these files in zsh instead of just PCManFM, and I can't figure out how to do that. I think the first step, after creating a mount point with sudo mkdir /media/cchfs, is to mount the filesystem like so:

sudo mount -t cifs -o user=NPI_HRRP/KArfer smb://cchfs /media/cchfs

but this produces the error Mounting cifs URL not implemented yet. From this question, which is about this error message, it looks like I need to replace smb://cchfs with //SOMETHING/cchfs or //cchfs/SOMETHING. But I don't know which, nor what the SOMETHING should be. I've tried a lot of guesses but only gotten pretty cryptic error messages.

Edit 1: Following these instructions on a Windows machine at the office, I got:

 C:\Users\karfer>net use
 New connections will be remembered.


 Status       Local     Remote                    Network

 -------------------------------------------------------------------------------
 OK           X:        \\cchfs\root              Microsoft Windows Network
 The command completed successfully.


 C:\Users\karfer>nslookup cchfs
 Server:  nsmcoint.medctr.ucla.edu
 Address:  10.2.14.10

 Name:    cchfs.cch.ucla.edu
 Address:  10.48.154.235

and so I tried:

sudo mount -t cifs -o user=NPI_HRRP/KArfer //10.48.154.235/cchfs /media/cchfs

which yields mount error(13): Permission denied (-v just adds mount.cifs kernel mount options: ip=10.48.154.235,unc=\\10.48.154.235\cchfs,user=NPI_HRRP/KArfer,pass=********) and in dmesg:

[ 2734.297317] Status code returned 0xc000006d NT_STATUS_LOGON_FAILURE
[ 2734.297332] CIFS VFS: Send error in SessSetup = -13
[ 2734.297591] CIFS VFS: cifs_mount failed w/return code = -13

I also tried //10.48.154.235/root in place of //10.48.154.235/cchfs, which didn't change anything.

I'm pretty sure I'm typing my password correctly. My password has capital letters and an exclamation point in it. Could that be a problem for mount although it's seemingly not a problem for PCManFM?

Edit 2: It looks like my credentials get accepted if I use KArfer in place of NPI_HRRP/KArfer. (It doesn't seem to make a difference whether or not I pass in domain=NPI_HRRP as well.) But now I get:

mount.cifs kernel mount options: ip=10.48.154.235,unc=\\10.48.154.235\cchfs,user=KArfer,pass=********
Retrying with upper case share name
mount.cifs kernel mount options: ip=10.48.154.235,unc=\\10.48.154.235\CCHFS,user=KArfer,pass=********
mount error(6): No such device or address

Changing cchfs to a few other things doesn't change anything, except that if I use X$ in place of cchfs, I get Permission denied again.

Edit 3: The output of smbclient -W=NPI_HRRP -U=KArfer -L //CCHFS is:

WARNING: The "syslog" option is deprecated

However, mount -t cifs -o username=NPI_HRRP/KArfer'%hunter2' //CCHFS /mnt, replacing hunter2 with my password, yields mount error(22): Invalid argument (after prompting for my password despite my inclusion of it in the command line). Same thing if I replace CCHFS with 10.48.154.235.

Answer 1

From the information given, NPI_HRRP is your workgroup, while CCHFS is your server.

First thing in solving samba issues for me is to try with smbclient first. If I have success getting access to the share with it, I map the required information to a mount line.

smbclient -U KArfer -L //CCHFS should give you a list of available shares on CCHFS. Maybe you need smbclient -W=NPI_HRRP -U=KArfer -L //CCHFS if you need to enter the workgroup first.

If this works, a mount line like mount -t cifs -o username=NPI_HRRP/KArfer%ToPsEcReT //CCHFS/x$ /mnt should work as well. If this fails and dmesg shows "Unable to determine destination address.", replace //CCHFS with //10.48.154.235, the IP address of your server.

A line like mount -t cifs -o credentials=~/.smbcredentials //10.48.154.235/x$ /mnt might be better to avoid having your password in your bash history.

Also, you cannot mount the "root" of a samba share. You might be limited to the mount of X$. Or is the share's name really "Root" in your case? This is really confusing.

Answer 2

Make sure /mnt/cchfs exists then try this:

 mount -t cifs -o username=youruser,password=yourpassword //10.48.154.235/cchfs /mnt/cchfs

Answer 3

Try the folowing line in /etc/fstab

//10.48.154.235/Root /mnt/cchfs cifs credentials=/home/hippo/.smbcredentials 0 0

This assumes that the IP address, sharename, and contents of your credentials file are all correct. If for some reason the share isn't mounted at boot you can try mounting it at login instead by changing fstab to read

//10.48.154.235/Root /mnt/cchfs cifs noauto,credentials=/home/hippo/.smbcredentials 0 0

and putting the following in /etc/rc.local

mount /mnt/cchfs
exit 0
