[QUOTE][u]Quote by: guitar24t[/u][p]The best option in my opinion is to reformat and reinstall the OS. I have had a few bad server installs that I just kept putting more and more time into without fixing the problem. It sounds like something bad! 😀
Good Luck,

Well, I tried doing an erase and install, set up DNS from scratch and tested forward and reverse lookups, tried the promotion again, and I got the same result (!!). I thought I was going crazy, so just for good measure I tried a 2nd erase and install, same result.

Does anyone have any idea WTF could be happening here? The hardware is an Intel Xserve with dual NICs, with only one plugged in and configured. I’m using the same install DVD that I originally used to install Leo server, which worked fine (including OD) for months until it broke recently.

Any help would be really appreciated.

Thanks so much – that post was really helpful, and the DNS trojan you mentioned seems to be exactly what happened. I found this article on it:

http://ithreats.wordpress.com/2008/01/11/analysis-of-osx-trojan-dns-changer/

which goes into some detail about exactly what it does.

[QUOTE][u]Quote by: MacTroll[/u][p]Well the segfault with the slapcat is where this is all failing?

Are you using SSL with LDAP? More specifically SSL with a private key that has a passphrase?[/p][/QUOTE]

Well, I thought the segment fault was the problem, since I couldn’t do the slapcat on the replica without getting that error.

*But* – I just tried disabling LDAP SSL on the master (it was using the “Default” certificate), and whamo – OD replication worked, 1st time. Is there a reason that the ever helpful MacTroll can tell me this in 2 seconds but the directory service logs on the replica couldn’t have given me a clue about this?

Thanks MacTroll – you and Josh and this site rule. 🙂

[MacDave]

One more clue – if I manually run:

sudo /usr/sbin/slapcat -l /Users/localadmin/Desktop/backup.ldif

on the OD master, it returns “Segmentation Fault.”

I’m all ears to any suggestions. 🙂

[MacDave]

Thanks for the suggestion – both servers are set to same time zone, and are within a few seconds of each other. Anything else I might try?

I’ve been having a very consistent and inexplicable reboot of my xserve G5, which seems to happen at least a few times per week. Retrospect 6.1.x is running on the machine, and backing up hundreds of Gigs to a FireWire 800 Exabyte VXA2 Packetloader 10 slot library (Josh: you mentioned these are often the cause?).

I turned off the ‘Restart automatically [after power failure | if the computer freezes]’ options in energy saver, and instead of reboots, the machine now just powers off.

Panic.log shows the following after every crash, which seems to implicate the packetloader:

To all the extremely helpful heavy hitters in this discussion: the following is an example of an ‘X-Spam-Status’ header that I’m getting in my incoming email:

X-Spam-Status: No, hits=3.92 tagged_above=-999 required=4
tests=DATE_IN_FUTURE_12_24, MIME_BASE64_NO_NAME, MIME_BASE64_TEXT

My spam threshold for appending the subject line is 4, and as you can see in the header, this message was marked as 3.92. So obviously becasue the message was assigned a score, that means SpamAssassin is working, right?

Now there’s nothing in my header that says ‘BAYES_xx’, but the original poster was concerned that he wasn’t seeing ‘BAYES_xx’ in his headers. If SA is working, doesn’t that mean bayesian filtering is working? What extra filtering benefits do the ‘BAYES_xx’ entries indicate?

Thanks to any who can elucidate for me.

uptimejeff: looks like the Tiger Server installed config file has the syntax wrong in a few spots. ‘auto_learn’ has been changed to ‘bayes_auto_learn.’ Great explanation here.

[QUOTE BY= Dof]Before using NHD test all the user applications because some of them don’t work in a NHD envirionment, Font Agen Pro and the latest Wacom tablet drivers are a real pain in the @#$.[/QUOTE]

I’m specifically interested in hearing about problems that people have had using networked Home directories. I have a client that I am going to switch over to NHD, and they primarily use adobe design applications, and Microsoft Office 2004. All client machines are Mac OS 10.3, server is Xserve Dual G5, with Xserve RAID.

Can anyone chime in here with potential application or other pitfalls in this scenario, aside from those mentioned above?
