I have a script that mounts all the shares from my Windows computer. It's basically:

mount.cifs //192.168.0.7/pictures ~/otherpc/pictures -o user=me,domain=mynetwork,password=12345,vers=3.0

..for about 10 lines.

Problem is, my network is DHCP. So every now and then I have to go change the IP in this script.

The script used to work this way:

mount.cifs //OTHERPC/pictures ~/otherpc/pictures -o user=me,domain=mynetwork,password=12345,ver=3.0

But at some point it started producing the error:

mount error: could not resolve address for OTHERPC: Unknown error

Nautilus resolves the name without a problem, though.

Is there a way to resolve the IP, store it in a variable and then use mount.cifs with //$variable instead of the IP directly in the script?

Thank you

I see two options you should try before fiddling around with storing the IP in a variable. (Besides, unless the servers already have a hostname, how will you figure out the new IP?)

• 
  

  Try mounting with hostname instead of IP, if it is a dynamic IP.

  
  
  

  mount.cifs //cifs.server.com/pictures ~/otherpc/pictures -o user=me,domain=mynetwork,password=12345,vers=3.0
  

  
  


• If the network is under your control, make DHCP reservations for the IP of the cifs servers.

I had exactly the same problem after an do-release-upgrade to Ubuntu 18.04.1 LTS. All shares that mounted happily before ended with this ugly

mount error: could not resolve address for server.domain.local: Unknown error

nslookup was resolving correctly, syslog and strace did not show anything.

In the end, the problem was the .local domain together with a change (possibly during the release upgrade) in the /etc/nsswitch.conf witch put the mDNS Avahi/Bonjour daemon mdns4_minimal before dns lookup.

So the problem was solved after I changed the order from

hosts: files mdns4_minimal [NOTFOUND=return] resolve [!UNAVAIL=return] dns 

to

hosts: files dns mdns4_minimal [NOTFOUND=return] resolve [!UNAVAIL=return]

I can't remember all helpfull links, but this one certainly did the trick: https://askubuntu.com/a/853284/810573
