Software tool development

I write tools for clients and for my own use that automate network administration, monitoring and operations.

SNMP proxy – a tool for forwarding SNMP traps while preserving the source IP address.
gsmon (Generic Session Monitor) – monitoring and reporting of user VPN access.
Muchacho – monitoring the data flow sent to a multicast group.

Odměny – data for technician bonus calculations drawn from service desk records (from 2020).

NaNoMan – a notification daemon for Nagios (2008).

analfire – analysis and audit of static routing on firewalls and routers (T-Mobile, 2011).
