Re: Migrated to Kubuntu, need assistance

Just for fun, try it with dbus-launch. Alt-F2

"dbus-launch kdesudo kate"

I'm curious to hear whether it works for you.

Re: Migrated to Kubuntu, need assistance

hmmmmm...so I tried it, and it worked...then I tried only kdesudo, and it works now also...not sure why it didn't before, but it hadn't worked for months...

Re: Migrated to Kubuntu, need assistance

@clenny, it's not obvious that there is anything wrong with your system. Are you sure you have connectivity with the ISP/broadband service? Here's what mine looks like:

dibl@jaunty:~$ cat /etc/network/interfaces

Re: Migrated to Kubuntu, need assistance

Excellent! Finally the file is formatted correctly. Now we get to ask the questions that should have been asked 2 pages ago.

The error says that there is no dhcp server in your network. (which is probably the reason you had problems from the start)

Now the question is how is your network configured? Your netgear switch is just a switch. Does your comcast modem support NAT? dhcp? If not, do you have a range of IP addresses assigned by comcast for all the machines on your network?

You said you had a windows PC and a macbook on the network. How are these machines configured?
At a minimum, what is the IP address?
What is the subnet mask?
What is the default gateway?

**clenny** · Aug 05, 2009, 07:11 PM

Re: Migrated to Kubuntu, need assistance

I'm not sure whether the modem supports NAT or not. I'm trying to find out. Here is the info I was able to gather:

Subnet mask 255.255.248.0
Router ID 69.243.61.4
IP Address 69.243.61.1
ethernet 00:19:e3:48:7e:10

my TCP/IP is IPv4 dhcp

I don't have a router per se, just the switch that is connected to the cable modem. I spoke with Comcast and according to the analyst I spoke with they don't support NAT. Not sure if this is significant but I have an EMTA modem since I recently signed up for the phone service. So both the phone and the Internet are routed through the same modem.

EMTA= embedded multimedia terminal adapter.

As a test, perhaps you could temporarily try plugging the kubuntu machine directly into the modem to see if the switch is somehow blocking the connection to the modem. Then run

Code:

sudo /etc/init.d/networking restart

reboot your modem and try again. leave it unplugged from the wall for 5-10 minutes.

**lmilano** · Aug 06, 2009, 06:43 PM

Re: Migrated to Kubuntu, need assistance

Maybe a stupid question, or maybe it was asked before, but is the dhcp stuff installed?

Code:

lmilano@grisell:~$ dpkg -l |grep dhc
ii dhcp3-client                3.1.1-5ubuntu8.1             DHCP client
ii dhcp3-common                3.1.1-5ubuntu8.1             common files used by all the dhcp3* packages

**clenny** · Aug 06, 2009, 09:10 PM

Re: Migrated to Kubuntu, need assistance

I unplugged the modem and let it sit for 5 minutes or so. I then connected the Linux box directly to the modem. I got the same result as before---sleeping.

As for whether the dhcp packages are installed; I would have to say no unless they were installed by default.
