work linux variants bye bye solaris

How sad, can't even give away sun fireblade systems anymore.
All sparc and x86 suns have gone away now.
Only ctie pizzeria remains - mainly using two ex-monash sun grid nodes and a pair of dell r710 dual xeon boxes.

Solaris has no place at my work anymore!!!!

At the moment, dell is winning the supplier race.

IPTV - so much confusion

IPTV seems to be raising it's head more and more.
Confusion reigns!!!!!!!

Telco view: Triple or quad play = way to raise ARPU and retention rate
TV industry view: just a broadcast medium

Customer view: VOD or broadcast TV perhaps even internet on tv

Does multicast fit in?
Does IPv6 fit in?
Answer to both of above = yes.

I think I need to put a huge summary somewhere.

Or perhaps point them to IPTV magazine and totaltele and vendors like erricsson and alcatel and microsoft.

My research work since 1998 could be a useful starting point!

And IPv6 and multicast integration with quicktime darwin streaming server = DSS and IPv6 enabled clients is also relevant.

I'd really like some stuff from thomson as well since they actually make set top boxes for iptv for many standards (microsoft, standards based .....) . Bits of thomson are near by to monash clayton.

ldap in mozilla and IPv6

The bug has existed for so long:
ipv6 enabled on winxp
thunderbird, mozilla etc address book hangs because the ldap connection tries to create IPv6 socket to IPv4 address.

So easy to fix, why hasn't it happened?
I'd fix it for them, but haven't followed it through.
I note some statements about IPv6 support in latest mozilla stuff, but so far no fix.

The ldap directory service attempts to
connect to the ipv6 socket ::ffff:xx.xx.xx.xx instead of the ipv4 socket
xx.xx.xx.xx

This is consistent with the last few years and on the thunderbird 3.0a1 that I
just downloaded/installed it still fails in the same way on a dual hosted ipv4
ipv6 machine.
Logging ldap:5 only produces the following:
0[274310]: nsLDAPOperation::SimpleBind(): called; bindName = '';
2348[278d2d0]: nsLDAPConnection::Run() entered

OSX 10.4.9 upgrade loginwindow crash

Mac OSX 10.4.9 upgrade led to loginwindow crash.
Repeatedly put you back at login window after you type your password in.
Safe boot made no difference.
This is a new intel powerbook pro model - from about jan07.

crashreporter showed loginwindow crashing.

Solution: Remove users keychain file!!!!!
Tried all the other things first though - you know: remove user preferences, delete user Caches
delete System/Caches and System/Library/Caches

This seems to have been a problem that nobody else has identified - may be unique to this box.
Was set up by using the import/migration from a powerpc based unit during system set up.


Perhaps this should go on macfixit or macintouch or apple proper.

expire on mammoth

for a in $(ls /home) ; do echo $a; chage -l $a | grep 2007 ; done

And then change the end date of some of them using
usermod -e 2008-02-20 ttngu35

distribute_passwd+group+shadow+gshadow

Why press "i" during mammoth boot up?

Why Oh Why?

redhat 9 system - swap partition on /dev/sda1 is commented out in /etc/fstab.

After major power fail, boot fails unless i is pressed for Interactive startup.

It hangs after enabling local filesystem quotas ...OK.
Which should have 'enabling swap space' as the next line showing on the console in a successful boot sequence.

So: is it related to having no swap partition/file?
Is it something else entirely?
