Description Fredrik Tolf 2004-10-25 08:03:40 UTC
The rwho protocol builds on link-local broadcasts, which means that two physically seperated subnets can't see each others' uptimes.

I'll attach a patch which adds a `-r' option to rwhod, which makes it forward cached uptime information to all local links. That way, if one has a router between two subnets, one can run `rwhod -r' on that router to make rwhod distribute the rwho information on all subnets it routes between.

Routing patch for rwhod

Adds a `-r' switch to rwhod that should be used when starting rwhod on a
router.

Fredrik, Seems better that upstream will include it first, since this is not a trivial patch.
Upstream email seems to be netbug@ftp.uk.linux.org.

Comment 3 Fredrik Tolf 2005-05-24 17:58:21 UTC
The problem is that I don't think that address maintained. I did send a message
anyway, however, to make sure. That was now over three weeks ago (May 3).

It may, of course, be that that address just isn't checked often, but
considering how the official netkit page was last updated 1999, I'm very
doubtful that there even *is* an upstream anymore.

Of course, I don't know for sure or anything, but that's my conclusions from the
facts that I've been able to gather.
Comment 4 Fredrik Tolf 2005-11-27 13:12:01 UTC
6 months have passed now, and I still haven't received a reply from
netbug@ftp.uk.linux.org, so I believe even more now that there isn't an upstream
for netkit anymore. Thus, would Gentoo mind including this patch?

By the way, it can be argued that this patch is indeed trivial, since it does
nothing as long as the -r command line option isn't given.

Please check bug #114694.
It includes a superset of this patch.

fixed, in cvs
