Yes, I did it using 2.4.18-2.4.21 kernels. You have to use ftp://ftp.isi.edu/rsvp/release/rsvpd.rel4.2a4-1.tar.gz and apply the patch that has been supplied by Craig Rodrigues from BBN to compile under RedHat Linux 6.2 and 7.0. ftp://ftp.isi.edu/rsvp/release/rsvp.patch.txt For the link to the kernel traffic control use Alexey Kunetsov's traffic control adaptation module ftp://ftp.isi.edu/rsvp/release/linux-tc.tar.gz (don't' forget to change Makefile to activate it - by default rsvpd uses testing stub) Dimitry -----Original Message----- From: Burnside, Andrew [mailto:Andrew.Burnside@xxxxxxxxxxxxxxx] Has anyone had any luck compiling rsvpd recently? I am trying to decide whether to use the ISI version or KOM-RSVP. I am running kernel 2.4.20.
