compiling src code for mrouted

[kaushal <kaushal () rocsys com>]

hello all,
             Where can I find compiling and tested mrouted code for 
linux?I have mrouted 3.81 code but it seems to be crafted for BSD.I 
tweaked the code to some extent,it is working but has problems with ppp 
netmasks.By default the netmask assigned for a ppp client happens to be 
/32 in my case and the mrouted is ignoring such interface treating it to 
be of the same sub net as the  eth0  interface (Thats correct).I have 
few more doubts in this aspect:

1.Is the PPP server supposed to provide a netmask not equal to /32 for 
its clients?If yes how should I do it in my ppp server?If no should I 
change the netmask mannually all the time?

2.Another point I notice with my pppd is that it assigns the same ip 
address at server end for all the ppp* connections but different ips at 
the other end,all with /32 netmask.Even this is creating a problem for 
mrouted. and hence it is ignoring those interfaces as per the warning 
messages.I came across this.

3.mrouted runs only if it has 2 vifs enabled.But in my case only one 
eth0 is permanent and all other are ppp interfaces which are 
dynamic.Hence when the box comes up with only one inerface and no ppps 
yet established,mrouted cannot run.That is obvious.But it is supposed to 
run when any ppp comes up.Can I do this configuraion part in 
mrouted.conf or should I tweak the mrouted source code?

Sorry for the big list.But I am stuck here.Any help would be greatly 
useful and immensly appreciated.

Thanks in advance.
