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.
Created attachment 42562 [details, diff] 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.
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.
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
