From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Cannot mount smb shared drive from the router on my Pop!_OS system. Can someone give me some assistance? (lemmy.ml)

Edit: I have added the share name at the end of the IP address and now I'm getting mount error(115): Operation now in progress. I haven't figured this one out yet either. My computer IP and the network drive IP are on the same network and within range. Both should be using the same gateway and DHCP.

I have tried just about every combination of parameters possible and nothing is working. It keeps spitting out a meaningless error and that error is the only thing in the log file too. I have tried a 100 different answers from across stack-overflow to no avail.

I'm running the command below:

sudo mount -t cifs //192.168.50.1/ /mnt/asus -o credentials=/home/user/.smbcredentials

and regardless of how many params I have removed it keeps spitting out : mount error(22): Invalid argument Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) and kernel log messages (dmesg)

I have referred to the manpage and verified that all of the args I'm using are valid. At this point I'm kind of at a loss. Are there file system args I need to add or something?

I can see the disk with all of the sharenames when I run smbclient -L 192.168.50.1, and I can navigate to it in the file browser, but I can't mount it for some reason. I have the workgroup name set under /etc/samba/smb.conf. I have tried enabling and disabling NT1. Does anyone have any ideas as to why it might be spitting out an invalid args error even when I removed every single argument?

The workgroup is set in the cfg file. I got a little further now. Since moving the credentials to the file I am getting a different error. Now I get mount error(115): Operation now in progress which is some sort of connection error. I was actually just logging verbose right before I checked back here and it just spits out the options from the config file and the error message. Still trying to figure this new error out since both the computer and the drive are on the same network, and within the same range.

OK, you may want to check dmesg or journalctl if there are further errors from the kernel - there is also a -v argument for mount, eg mount -t cifs -v //SERVER/$share /mnt --verbose -o... that might help.

Don't know if you've found this already (and apologies if you have!) but this suggests some not obvious solutions https://superuser.com/questions/430163/cifs-share-mount-errors

Also (brain dumping) if you've successfully mounted it via the file browser, do so again and then check mount to see what arguments/options the CIFS mount is using - it might yield some important differences.

Thanks! That last option is something I thought of too, but I didn't know what to do to get that information. I tried properties in the file explorer, but that didn't work. Do I just type mount into the terminal to get a list of mounts? I'll definitely try all of this after work. For now I'm exhausted from staying up until 1:30 am trying to get this figured out.

Sorry, I was thinking file browser mounts would appear in mount, but they don't.

You should be able to list file browser mounts in a terminal using gio mount -li after mounting via the file browser, and it will list the SMB mount it's using, ie smb://SERVER/$share/

This annoyingly doesn't give us the username or domain for the SMB share, and to get that if the server and share looks OK we have to run gvfs (what the file browser for PopOS uses in the background) in debug mode and re-mount the SMB share; in a terminal run pkill gvfs; pkill nautilus; LANG=C GVFS_DEBUG=1 $(find /usr/lib* -name gvfsd 2>/dev/null) --replace 2>&1 ; this will unmount anything in the file browser but will show what username and domain the file browser is using to access the SMB share, for example after clicking on a share in the file browser, among other logs, I get;

smb: do_mount - URI = smb://absolution.local/samshared
smb: do_mount - try #0 
smb: auth_callback - kerberos pass
smb: auth_callback - out: last_user = 'samblack', last_domain = 'SAMBA'
smb: do_mount - [smb://absolution.local/samshared; 0] res = -1, cancelled = 0, errno = [22] 'Invalid argument' 
smb: do_mount - enabling NTLMSSP fallback
smb: do_mount - try #1 
smb: auth_callback - ccache pass
smb: auth_callback - out: last_user = 'samblack', last_domain = 'SAMBA'
smb: do_mount - [smb://absolution.local/samshared; 1] res = -1, cancelled = 0, errno = [22] 'Invalid argument' 
smb: do_mount - try #2 
smb: auth_callback - normal pass
smb: auth_callback - reusing keyring credentials: user = 'samblack', domain = 'ABSOLUTION'
smb: auth_callback - out: last_user = 'samblack', last_domain = 'ABSOLUTION'
smb: do_mount - [smb://absolution.local/samshared; 2] res = 0, cancelled = 0, errno = [0] 'Success' 
smb: do_mount - login successful
smb: send_reply(0x55ea6ffe5450), failed=0 ()

This should give the username and domain that connects and can be used in the credential file.

Once this is done, you can exit the terminal with gvfs running and you should be able to close and re-open the file browser and the mounts should just re-appear normally.

Hopefully this will give enough information as to why the file browser mount works and the mount command doesn't.

This is amazing! Thank you very much. I'll try this out tonight and hopefully get somewhere with it. I'll let you know either way. Thanks again!
