The sample code that Kees pasted above won't work, since he has the "-t 15" following the "-r ANS". In any case, I'm attaching another patch that solves this problem to the bug. I've tested the timeout and it behaves as expected.

That's precisely the kind of feature that landscape-client and the Landscape server already offer. But long histories might not be good candidates for the login message. The idea is offering a quick hint about how things are generally going, together with any outstanding warnings that are likely worth keeping an eye on. -- Gustavo Niemeyer http://niemeyer.net -- ubuntu-server mailing list ubuntu-server@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-server More info: https://wiki.ubuntu.com/ServerTeam

This is just one more feature we're implementing in Landscape, and in this case it'll benefit even administrators that are not Landscape users. If you want to reuse it in different situations, the software is GPL and it should be trivial to just run it from cron and ask it to mail the information anywhere you want, for instance. > And actually that type of expanded motd message may be more useful on > my desktop computer where I login more often than on a server that > just happily runs in a corner of the server room serving services or > disk space without human intervention for days at end.

These days I'm playing with the getting old Big Brother (www.bb4.org) to centralize messages from various servers into one web page. Now looking at some of the info I have been tracking that way from my servers: connectivity, system load, disk usage (i.e, specific important disks are nearly full while other disks I can ignore), if specific processes are still running (by default big brother tracks cron), and if specific services are online and listening (ftp, http, ssh). I could see some of these bits of info being useful in that motd message. It is on my to-do list to tied into Dell's OMSA and track down as well more hardware specific basic info (temperature, state of disks and raid, are the fans working, etc).

If you would like more information please contact me. The only problem i've noticed is with DRBD and OCFS2, apparently Ubuntu (in contrast to Suse(SLES) and Redhat (RLES)) currently lacks OCFS2 Userspace drives in the 2.6.24 kernel. This means heartbeat can't manage your OCFS2 resource (but it can manage DRBD if you take care of the OCFS2 drivers yourself) until at least 2.6.25 when i'm told the drivers are likely to make their way in to Ubuntu. As documentaion from Ubuntu is very limited and there also seems to be no other users using Ubuntu server with RHCS, i decided to tune in and maybe could provide some experiences if they are of help.

Re: ebox bind apache
Webmin and Debian style Apache did not play well together. Ebox doesn't do Apache at all. I've got hundreds of domains and virtual websites and anything that would lighten the load would be welcome. I could roll up my sleeves and write some scripts.
