Located in ftp://ftp.sgi.com/sgi/ipmcast/IRIX5/5.3/mrouted3.8.tar.Z
This is a set of changes to the multicast routing support for
IRIX 5.3 to include the release 3.5 of the kernel modules, and
3.8 of mrouted. A few bugs are fixed since the December snapshot.
Rate limiting now works on multi-processors, and mtrace now returns
reasonable statistics.
Copy the correct bsd.a and ip_mroute.o to your /var/sysgen/boot,
copy mrouted, and reboot. There is also a new netstat needed for
the -M and -Ms options to work. Note the -C option of netstat
and screen "8" to get detailed statistics.
cp bsd.a. /var/sysgen/boot/bsd.a
cp ip_mroute.o. /var/sysgen/boot/ip_mroute.o
cp mrouted netstat /usr/etc
autoconfig
reboot
Where the is:
IP19 Challenge L and XL, Onyx L and XL
IP20 Indigo with R4000
IP22 Indy, Indigo 2, and Challenge S
IP5 Older R3000 machines, including IP7 (not tested)
IP12 Original R3000 Indigo (not tested)
For example, for IP22:
cp bsd.a.IP22 /var/sysgen/boot/bsd.a
cp ip_mroute.o.IP22 /var/sysgen/boot/ip_mroute.o
cp mrouted netstat /usr/etc
autoconfig
reboot
Limitations:
The new features have not been extensively tested.
In a network with mrouted 3.4, you will messages complaining
about "duplicate prunes", due to 3.4 bugs. These
are limited to one every ten minutes, and can be safely
ignored, or upgrade the offending routers to mrouted 3.8.
This bsd.a includes the fixes in various IRIX 5.3 Patches
to fix some TCP and UDP problems on busy servers. If you
are NOT running patch 530, then tpisocket.a might be
incompatible (i.e. svr4net programs might hang). If you
get an error about "somaxconn" not being defined,
it means you have not installed patch 317 or 530. Copy
the "bsd" file here into the /var/sysgen/master.d directory.
If you get an error about "swinput" etc. being undefined then
you need to copy if_sw into /var/sysgen/master.d (from
Patch 639) and add a "USE: if_sw" line to
/var/sysgen/system/irix.sm. See "man 4 system" for
more information on irix.sm.
The IRIX 6.2 release has mrouted 3.8, so just use the
installed binaries (or 6.2 patch 1247 to fix the MP problems).
If you want support, please install IRIX 5.3 patch 1356 or
is successors.
Please report any problems to nowicki@SGI.COM, only
after trying the "bsd" and "if_sw" files as described above.
