Syntax error in /etc/nbdtab when using ip as host

[Stav88]

I think it follow ##119 (it work in a previous build)

Environnment

Distribution : Manjaro aarch64 (pinebook pro)
Package : nbd 3.23-1

Scenario

• Create a file /etc/nbdtab with following :

  nbd0 192.168.0.14 cdrom persist
  

• Try to mount nbd0 :

  nbd-client nbd0

• Returned error :

  parse error parsing /etc/nbdtab: syntax errorERROR: no valid configuration for specified device found
  

My analyze

• In nbdtab_parser.y, I see that second column is a STRING token
• In nbdtab_lexer.l, I see then the STRING token must not contain dot .
• Ip address containes dots ., so it is not a valid STRING token

Workaround

• define a hostname without dot in /etc/hosts

  ...
  nbd-server 192.168.0.14
  

• use this hostname in /etc/nbdtab

  nbd0 nbd-server cdrom persist
