Ubuntu Networking :: Configuring Postfix Send And Receive Across Ethernet
Sep 27, 2010I am would like to configure postfix to send and receive email across Ethernet (just for now). I have two machines with postfix installed both using Ubuntu 10.04 directly connected with an ethernet cable. I have successfully configured a machine to send email to gmail, however i have been unsuccessful in having these machines send email back and forth. I have been interested in setting up a little mail server at home and have just been trying some simple projects with postfix to start with. At this moment i am using ip addresses and am not concerned with using a dns server
machine A: has a fixed ip of 10.137.202.1, hostname = mail.me.com,
machine B: has a fixed ip of 10.137.202.20, hostname = mail.ubuntu.com
in the /etc/hosts file I map each hostname to ip address receptively (not sure if a good idea, but at this point I have been trying everything)
So I will execute from Machine B
echo "Here is a message" | mail -s 'Hello' cmd@[10.137.202.1]
I currently get from mail.log timed out while receiving the initial server greeting. I get from mail.err valid hostname or network address required in server description #[10.137.202.1]. Obviously when I run the mail command from cmd user i do not receive anything. I can receive mail from myself if from machine A, I sent an email using the command above. I would just like to send email from machine B and receive it on machine A via direct Ethernet connection. I have been through postfix documentation and have also read the postfix definitive guide and have had no luck.
Here is a recent main.cf as I have tried getting this to work (this is for machine A however, similar for B)
# Debian specific: Specifying a file name will cause the first
# line of that file to be used as the name. The Debian default
# is /etc/mailname.
myorigin = /etc/mailname .....
Networking :: Using Ethernet To Power WiFi Network And Setting Up WiFi?
Aug 23, 2009I have an old PowerBook G4 that I would like to use as a 'dummy' computer for learning wireless penetration (WEP/WPA attacks) more effectively. I had been using a wireless router, but I gave it away I can use Mac OS X to share an ethernet connection over wifi, but this is _very_ un-configurable. You get two options only, WEP and a key-length. So, I would like to install someway to make this wireless connection more configurable.

Feb 1, 2010I just installed fc12 (64 bit) on a t61p laptop. If the ethernet is connected when the laptop is powered up, it is seen and is present in the network configuration hardware profile. If I wait until the machine is booted before I connect it, it isn't present. How do I make it so that I can connect the ethernet at any time?
Except for this minor nit, everything else worked perfectly right out of the box.
Ubuntu Networking :: Alfa AWUS036H Adjust Power - Unknown Transmit Power Information
Jun 21, 2010I am using Ubuntu 10.04 64-bit and I purchased a new ALFA AWUS036H wireless card. I would like to know if this "1Watt" wireless card is configured for full power. iwlist wlan0 txpower results:
wlan0 unknown transmit-power information. Current Tx-Power=27 dBm (501 mW). It appears to me that I should be able to increase the power. "iwpriv wlan0 highpower 1" does not work.

General :: Configure 1000 Base T Ethernet Card To Send At 1000 Base T?
Sep 22, 2009I have a router that is 1000 Base T and two computers each with ethernet cards that support 1000 Base T. All are equipped with Cat 5e cable. Before I had a router that only went up to 100 Base T and I would setup one box with linux running proftpd. On the other box,I would use win xp pro and use firefox to ftp into the other box and download a file. Download speeds went up to 11.2 MB/sec. Now when I switched routers, I expected something like 120 MB/sec but I'm only getting 5.3 MB/sec. What do I need to change?

Ubuntu Networking :: Dual Ethernet Networking - Lose Internet Connectivity?
Apr 18, 2011I have a server with two ethernet ports. I configured eth0 to be static, set at 10.1.10.148. I plugged in another router into the other ethernet port in order to configure that router. I configured eth1 to use dhcp. Using /etc/network/interfaces rather than gnome network manager. When I did this, I lost internet connectivity (internet routes through eth0 of course)
- Why did I lose internet connectivity?
In order to recover internet activity, I had to disconnect the new router on eth1 of course, and do sudo ifdown eth1. That wasn't enough however. After rebooting numerous times and pulling out my hair, I finally tried configuring eth0 as dhcp, rather than static, and this fixed the problem.
- Why didn't sudo ifdown eth1 solve the problem? What information was saved between reboots that somehow remembered that I plugged in the new router? Because my thinking was if /etc/network/interfaces was identical, and the network topology was identical, after a reboot everything should be restored, but it wasn't.
Ubuntu :: Share Internet From 1st Ethernet AND To 2nd Ethernet And Wifi Card?
Feb 8, 2011I am basically wanting to use my Ubuntu 10.10 computer as a router. Note: Before you say just get a router please note that I am poor/cheap. I have two ethernet connections and one wireless connection on my netbook. I want to share the internet connection that is going into one of the ethernet cards through the other ethernet card and the wireless card.
DSL-->1sr Eth --> 2nd Eth (currently works)
DSL-->1sr Eth --> Wireless Card (Adhoc) <--(connects with limited connectivity AKA no internet)
The 2nd Ethernet card already has working internet, but when I connect to the Wireless card (through an Adhoc network), it cannot get an IP (I believe).
Debian Multimedia :: Xfce4-power-manager Doesn't React To Power Button / Fix It?
Jun 4, 2010I use Squeeze with Xfce. My problem is that recently (after the xfce updates) the xfce power manager doesnt react to the power button - it is set to suspend. I dont have gnome-power manager or anything like it running.
If i reboot the computer, the power button will work but if i suspend and resume, it doesnt work again.
The computer is built on an Asus M3N78-VM mobo (2GB RAM/Athlon3200+ single core).
acpi_listen detects the button press.
Any thoughts?
Hardware :: Power Monitoring - Power Quality - Voltage Changes And Outages
Apr 4, 2011I'm looking for any power monitoring devices for Linux to allow monitoring power quality, voltage changes, and outages. This would be for North American three phase power system. I want to have this data fed live to my own program. It should be something much better than just jury-rigging a circuit to fee the power waveform into 2 or 3 audio cards.

I could use power conservatively, and performance would suffer a bit, but longer batt life,or I could have it automatically detect, or I could have the apps use all the power they want and then some. I'm looking to reinstall that app. What was the name of it?I can't remember, and so far, can't find.

May 11, 2010I installed 10.04 today, and I can't get any connection through the LAN. I've tried some stuff on my own, but I've been unsuccessful so far. It's not a hardware or connection issue, as it works perfectly fine in Windows 7. I haven't had this issue in any previous version of Ubuntu (or any Linux distro for that matter).The weirdest part is I booted from the installation CD as as LiveCD, and everything worked perfectly fine. It only stops working after I actually install it. Here's the results of ifconfig:

Oct 17, 2010I have been using Ubuntu for quite a while now (~3 years.) I recently installed 10.10 on an HP Mini 1000. The installation went fine, but now I am puzzling over how to connect to the internet. When I plug an ethernet cable into the netbook, the port light lights up, but the system does absolutely nothing. Under the connections menu on the top panel, it just says disconnected. Also, the wireless connection section states that the device is not ready because firmware is not installed. Most solutions I see for problems of this kind are to download the drivers, but I cannot do that because neither connection works.

How can I locate the right wireless driver? In the past, I have always been able to simply plug in the ethernet cable and get the necessary updates.

Also, I have the french version so i'll do my best to translate the terms in english. I have a major problem: i can't connect to internet by ethernet cable or by wireless. The network icon is always empty. It doesn't detect the ethernet cable and the wireless networks around. I've tried different things i found on forums. I'v reinstalled the b43 package and rebooted. At the beginning i was only having problem with the wireless; i could connect via ethernet. But on one forum, a dude suggested the command
