Hi, I have gotten all sorts of mbone crap to compile after a bit of fighting with tcl and tk on their silly little requirements, and I do remember getting vic, vat, rat, and nv? was it? to compile. Some time ago, I sent out a note concerning how to compile mrouted with glibc. I specifically remember having to edit some header file and I notified GNU of their deficiency. It's not too terribly bad, it just takes time. I am not sure I understand your second question, but if it is a fixed address, you'll want to fire up mrouted when your link comes up. Then, mrouted will likely nail your link up. You may end up fighting a losing battle with mrouted because of the flood-and-prune effect. The solution I found to be most effective was to use a 2500 at my end and run pim-sm over the link. This provided the best answer after fighting for weeks over the issue. _J Ross Golder said: > Everywhere I look, I find all the usual mbone tools for Linux are > compiled in 96/97 against dynamic libraries such as libc.so.4 !?
