Mapping CIFS server shares to local drive with autofs

nmap <server>

Is the old server still online?

The test account is disabled, but the server is still online:

Neither 139 nor 445 are open on that server… ??

Sorry, that was the virtual machine server. Perhaps you meant the CIFS server.....

You can see 445 is open on the CIFS server.

NetBIOS (139) isn't - can you check whether it was on the old server?

zekebsatx · 2020-02-05 21:09:32

Just checked, 139 was not open on the old server.

EDIT: Just updating to note that the IT person was able to map the CIFS share to an NFS server, which I could access. We had to push my local user permissions down to the file tree to allow me rw access, but everything is now working as expected.

Not marking this solved, because the original problem (mount.cifs permission denied) still persists.

I don't know if the response is still interesting, but hopefully my issue helps you (the poster) ...

I was just experiencing failing smbmounts (via /etc/fstab + automount) although nothing had obviously changed on my arch installation.
After some playing around I found that the reason was my password.
It contained a ','-character. For quite some time this worked perfectly, but failed since yesterday.
From the dmesg entries I found mount.cifs reclaiming a wrong parameter, which was identical to my password part after the ','

Changing the password to one without ',' helped.
By the way, password has been within a credential file.
Maybe other special characters have some special meaning if sent to the server, which they hadn't before.
So, just try to replace all special characters by different ones (or better only numbers and letters, if your server allows that).

Just my 5 cts :-)

Please do not necrobump unrelated threads.
The comma is probably the only problem. https://www.reddit.com/r/archlinux/comm … our_samba/
