/etc/mail/service.switch
Busy for hours to troubleshoot a sendmail(Centos5.5) to find out
why it insists on trying to deliver mail directly to A record addresses
rather than via MX records. I was lucky that Peter documented
his solution in 2002 so I can use it 9 years later!

Thanks Peter!
I saw this command and wonder if I could have used it: echo '3,0 student@sub.domain.edu' | sendmail -bt

Finally Working GNS3 ASA/ASDM6.31 on Ubuntu 10 & 11
I was struggling to tftp asdm-631.bin file to a running ASA and keep getting an error message
right after uploading 2MB! So, I found a way to transfer it offline!
On your machine that runs GNS3,
$ sudo -i
(find the GNS3 tmp file for your ASA)
Turn off ASA1 (I assumed you are working on ASA1)
# cd /opt/GNS3/tmp/ASA1
# rename/delete the current FLASH (you will loose all the modifications!)
# qemu-img create FLASH 256M
# qemu-img info /opt/GNS3/tmp/ASA1/FLASH
Turn it on and let the FLASH get initialized and then turn it back off.
# losetup /dev/loop0 FLASH
# kpartx -av /dev/loop0
# ls -alF /dev/mapper/
# mkdir test
# mount /dev/mapper/loop0p1 test/
# cp /root/asdm-631.bin test/lina-data/1/soft/
# umount test/
# sync
# kpartx -d /dev/loop0
# losetup /dev/loop0 -d
Start ASA1 and you should be able to see ASDM file on your flash!
and can be configure your ASA for ASDM access.

Accessing tftp://10.10.10.1/asdm631.bin...!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Writing file disk0:/asdm631.bin...
Losing too many ticks!
TSC cannot be used as a timesource.
Possible reasons for this are:
You're running with Speedstep,
You don't have DMA enabled for your hard disk (see hdparm),
Incorrect TSC synchronization on an SMP system (see dmesg).
Falling back to a sane timesource now.
