I’m having problems mounting /mnt/data on my newest vmware VM. I’m not sure what next to try next to get /mnt/data to show me my shared folder – I’m doing it through /etc/fstab in Ubuntu. So I thought I’d ask for ideas on anything I might’ve overlooked.
VM IP address is 192.168.136.143, Ubuntu Version 18.04 Windows Laptop [216TN533] IP: (Ethernet adapter vEthernet (WSL)) 172.19.64.1
(Wireless LAN Adapter Wi-Fi) 192.168.1.6
(Additional detailed version information at end of this message)
In /etc/fstab started with (password elided in this message as ********):
//216TN533/UbuntuShare /mnt/data cifs username=kafkaetl,password=********,uid=nobody,iocharset=utf8,noperm 0 0
sudo mount -av
returns:
mount.cifs kernel mount options: ip=172.19.64.1,unc=\216TN53\UbuntuShare,iocharset=utf8,noperm,uid=65534,user=kafkaetl,pass=******** mount error(13): Permission denied Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
From the mount man page about the above error:
If you get the error "mount error(13) permission denied", then the server denied your access. Here are the first things to check:
• Are you using a valid username and password? Does that account really have access to this folder?.
o I can login as kafkaetl so I believe that is correct
• Do you have whitespace in your credentials file? It should be password=mspassword, not password = mspassword.
o No whitespace
• Is the security setting correct? The most common is sec=ntlm, but you can also try the other options listed at the mount.cifs man page. The man page list leaves out the option sec=lanman for some reason, but you should try that one as well (see discussion).
o Added sec=ntlm
• Do you need a domain? For example, if you are told that your username is SALES\sally, then actually your username is sally and your domain is SALES. The fstab entry should read: ...username=sally,password=pass,domain=SALES,... Or: ...credentials=/path/to/file,domain=SALES,...
o Added domain=216TN53
• cifs-utils and nfs-common are installed.
• Nothing has been changed on the share on the windows side
Then setting security (sec=ntlm) option in fstab:
//216TN533/UbuntuShare /mnt/data cifs username=kafkaetl,password=********,uid=nobody,iocharset=utf8,noperm,sec=ntlm 0 0
results in:
mount.cifs kernel mount options: ip=172.19.64.1,unc=\\216TN53\UbuntuShare,iocharset=utf8,noperm,sec=ntlm,uid=65534,user=kafkaetl,pass=********
mount error(2): No such file or directory
From dmesg the concurrently logged message is:
(Screenshot)
As I investigated, I noticed that on 2 sequential ip addr requests, the V4 IP address reported had changed (w.x.y.145 to w.x.y.146) The only activity between the two invocations was the login screen had appeared.
I checked the firewall, and a sudo ufw status returns inactive.
Any additional ideas on why I can’t see the contents of UbuntuShare as /mnt/data? I see the changing IP address as shown above as a problem, which I don’t have the root cause for.
