scotty - network management extensions to tcl scotty is a tcl extension which allows to set up TCP and UDP connections, to send various ICMP packets, to query the domain name system (DNS), to check clock screw using the NTP protocol and to query various SUN RPC services (like rstat and mountd). Included in this package is an interface to SNMPv1 and SNMPv2. The SNMP stack was written from scratch to provide an efficient and portable tcl SNMP extension.

This allows you to implement your own specific MIB without getting in contact with the lowlevel ASN.1/BER stuff. tkined, a very nice graphical network monitoring tool based on scotty is available as pkgsrc/net/tkined.
