Ubuntu: sysv-rc-conf - missing admin tool

I'm coming from RedHat school.
After switching to Ubuntu I missed chkconfig tool for managing services.

But Ubuntu provides same managing interface with sysv-rc-conf instead.

$sudo apt-get install sysv-rc-conf

Nice!

Peoplenet on Ubuntu Linux

I've got CCU-550(3G/UMTS) modem.
I've never installed modems on Linux before so I just hoped that newest distros have right tools to do that.

I wanted to start using it quickly therefore began with NetworkManager's PointToPoint connection option. But it didn't want to work...

Then I looked at pppd stcripts. But it didn't work for me either...

At that point I didn't have internet access so the only option i could progress with was reading man pages for wvdial.

Interesting what man page says about wvdial - PPP dialer with built-in intelligence.
And it turned out to be true :)

So i launched
$man 5 wvdial.conf

copied sample configuration to /etc/wvdial.conf and modified to look like:
[Dialer Defaults]
Modem = /dev/ttyACM0
Baud = 460800
Init = ATZ
Phone = #777
Username = 80921111111@people.net.ua
Password = 111111


To get the proper Modem location i did:
$dmesg |grep tty
[ 164.384650] cdc_acm 2-1:1.0: ttyACM0: USB ACM device


Then launching:
$wvdial

I got it working:

$ ifconfig |\grep -A 1 ppp
ppp0 Link encap:Point-to-Point Protocol
inet addr:my.ip.addr.ess P-t-P:pp.ip.addr.ess Mask:255.255.255.255


Wow! Nice! :)

using rake with sudo

I was installing datamapper gems like:
gmarik@gm:master\dm-more.git$ sudo rake install
sudo: rake: command not found

sudo restricts environment settins:
$ sudo env|\grep PATH
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin
As you can see rake path is not included:
$ which rake
/usr/local/lib/ruby/gems/bin/rake

You can edit sudo PATH to include /usr/local/lib/ruby/gems/bin.
=== UPDATED AT 2008.12.04 =====
or run rake with PATH set like:
sudo env PATH=$PATH rake
===============================
Bu i just symlinked rake:
$sudo ln -s `which rake` /usr/local/bin/

Now it works:
$ sudo rake --version
rake, version 0.8.3
