Here is a couple of hacks I made to iij-ppp, I'd like these capabilities 
added.

to main.c so that is would start ppp negotiation in auto mode.  This is so
it will work with slirp, it also still works with my straight ppp provider
that isn't in my local call whereas my slirp connection is!

    CcpInit();
    LcpUp();
  
!   if (mode & (MODE_DIRECT|MODE_DEDICATED))
      LcpOpen(OPEN_ACTIVE);
    else
      LcpOpen(VarOpenMode);

    CcpInit();
    LcpUp();
  
!   if (mode & (MODE_DIRECT|MODE_DEDICATED|MODE_AUTO))
      LcpOpen(OPEN_ACTIVE);
    else
      LcpOpen(VarOpenMode);


to command.c so I can run a script from the config file when the link comes
up (like dequeue any mail waiting on my system or at my providers site for
me and update my named config file since slirp's DNS server keeps changing
depending on the machine I get connected to)

+   }else
+     printf("Use ``shell <command>''.\n");
+   return(val);
+ }
  
  static int
  AddCommand(list, argc, argv)

The reason why I did this, is that my phone bill was to expensive, my ppp
connection was not in my local calling area and I had a shell account that
was.  So I run two iij-ppp auto sessions, a generic one that uses my 
shell account with slirp for general net surfing and the ppp-account to 
dequeue smtp mail waiting for my machine.  Now I just have a ping in my
crontab and that automatically dequeues my mail waiting for me once a day
and my phone bill is a lot lower.
