I will have to say, that rtrmon is one of the best tools that we have for management of our routers.
that's nice to hear. and did i mention that it does not require clear text router passwords to be stored in the file system like some tools i know of?
Simple, elegant, hard to port to non BSD, does all kinds of routine tasks easy.
re: hard to port. well, the folks here who write that kind of code are periodically available and if i could find more companies like genuity who are willing to fund work like rtrmon and vulture (which means: isp tools which help everybody but are not competitive advantages and which can therefore be freely redistributable even though someone had to pay to implement them) i would certainly have had someone port rtrmon to, say, solaris and NT by now.
