Have several thoughts about error messages, in reply to SL's comments.
Here's one, maybe more later...

There are high level ways to do it, i.e. a wrapper script. Attached is
a runnable script that shows the concept, and also may be useful to
users** in the same boat:
# cifs_samba_check.sh host share
% cifs_samba_check.sh 192.168.1.51 hdb1 ; echo $?
host 192.168.1.51 exists
samba/cifs ports present on 192.168.1.51
share hdb1 exists
0
% cifs_samba_check.sh 192.168.1.51 hdb9 ; echo $?
host 192.168.1.51 exists
samba/cifs ports present on 192.168.1.51
can't find share hdb9
3
% ~/cifs_samba_check.sh 192.168.1.59 hdb9 ; echo $?
can't find host 192.168.1.59
1
(Haven't put in a util check or '--help' yet...)
(**if necessary: apt-get install nmap host smbclient )
High level net utils are called from three true/false functions:
host_exist() # syntax: host_exist host
{ host $1 > /dev/null 2> /dev/null ; }
# ports 139 & 445 are a bit of a guess.
samba_exist() # syntax: samba_exist host
{
[ `nmap -p "139,445" $1 | grep 'tcp open' | wc -l` = 2 ]
}
share_grep() # syntax: share_grep sharename hostname
{
smbclient -L $2 -N 2>&1 | \
grep -A 99 "Sharename Type Comment" | \
egrep -m 1 -B 99 "^$" | tail -n +3 | head -n -1 | \
grep -q $1
}
...my networking skills are feeble, and I hope there are better ways of
writing such functions.
