A shell script to monitor samba servers and shares. Usefull to check availability on many samba servers/shares from a single host.
Install samba-tools for your distro. Name may vary, therefore check you have smbclient available. You will also require smbtree if you want to check unallowed SMB shares. Untar this package, put hobbit-samba.sh in $BBHOME/ext directory Put hobbit-samba.conf in $BBHOME/etc directory Configuration details are in hobbit-samba.conf and almost well documented in. Modify variables (lines 40 and following) to fit your local configuration
Add samba to you $BBHOME/server/bb-hosts line for the host running this script
