My trusty old LG Chocolate died on Tuesday so I've replaced it with a Droid. Really cool phone. The only thing I wish it had is multi-touch, but I can't really complain about that. (edit 556) Permalink

When I tried starting Microsoft IIS I got Error 0x08ffe2740, which indicates a port conflict with port 80, another application is using that port.

It was Skype, Skype uses port 80. I turn it off and now IIS Server is running.

This morning when I came to work the phone system, Internet connection, and printer were all down. We had a wind storm over the weekend up here in Bellingham, WA, and a few blackouts. The print we fixed, by tilting the print head back (away from the drum).

The Asterisk 1.2 phone system was also dead, the power off, it's an old computer that does not seem to have the feature that turns it back on when power is restored. But when I restored power it gave me this message over and over:

Asterisk ended with exit status 1
Asterisk died with code 1.
Automatically restarting Asterisk.

killall -9 safe_asterisk
killall -9 asterisk
/etc/init.d/asterisk start

I made Asterisk load successfully by commenting out the last block of lines in the /etc/asterisk/zapata.conf file, but there were no incoming phone lines, just internal intercom! No good. So I messed around with lsmod and insmod, zttool, and ztcfg. zttool told me that the zaptel devices were not there. Fore awhile I thought the cards had gone back during the black-out. But I finally fixed it by doing this:

# modprobe wcfxo
# modprobe zaptel
# ztcfg -v

This fixya.com is a nice little site, I'm getting advice on how to fix our Xerox Phaser 8500, we're getting Error 07,010.43:93504

It means that the head is stuck and can't move. I haven't gotten physical access to the printer yet. (edit 549) Permalink
