MySQL fails after upgrade to 5.1 on Debian Squeeze

Are you running Debian Squeeze?
Did you upgrade to mysql-server-5.1 ?
Are you getting a message like this?

Starting MySQL database server: mysqld . . . . . . . . . . . . . . failed!

Did you read /usr/share/doc/mysql-server-5.1/README.Debian.gz ?
Go read it again and this time *comment out* skip-bdb in /etc/mysql/my.cnf:
perl -i.bak -pe 's/^(skip-bdb)/#$1/' /etc/mysql/my.cnf

uHOWTO: Use your N95 8G as a bluetooth modem under Linux with Telcel

For completeness, here’s a followup to my post about using a Nokia N95 as a bluetooth modem under Linux. This is a working wvdial configuration for use with Telcel in Mexico.
Remember to enter your SIM’s PIN in pin-telcel, and refer to my previous post for complete instructions.

[Dialer pin-telcel]
Modem = /dev/rfcomm0
Baud = 460800
Init1 =AT+Cpin=XXXX

[Dialer telcel]
Phone = *99***1#
Username = telcel
Password = telcel
Stupid Mode = 1
Dial Command = ATDT
Check Def Route = on
Dial Attempts = 3
Modem = /dev/rfcomm0
Baud = 460800
Init2 = ATZ
Init3 = ATQ0 V1 E0 S0=0 &C1 &D2 +FCLASS=0
Init4 = AT+CGDCONT=1,"IP",""
ISDN = 0
Modem Type = Analog Modem

To use it, enter

# wvdial vodafone-pin
# wvdial vodafone
