Ubuntu :: Configure Connection After Every Reboot
Mar 17, 2010
I am using Ubuntu Intrepid now, (no more Karmic, at least for some time)...
I connect to Internet through a proxy server. I have to configure my connection by going to Network Manager and then editing IPv4 settings, making the address selection manual instead of DHCP and then enter the static IP provided to me by the server and also the address of my gateway... Then I have to go to the Network Proxy under System --> Preferences and set my system proxy (Apply System Wide)...
Well that seems normal, except that I have to do the connection configuration part every time I reboot... Every time i reboot, the connection is back to default i.e.
Quote:
Name: Auto eth0
IPv4 Settings --> Method: Automatic(DHCP)
I have to change it again to
Quote:
Name: IST-LAN
IPv4 Settings --> Method: Manual
IP Address: 192.168.xxx.xxx
Netmask: 255.255.255.0
Gateway: 192.168.xxx.xxx
One of my friends reported the same thing to me after a fresh installation... So maybe that is a bug in the Network Manager of Interpid... I need to know a workaround, or a repair.

I have a headless Jaunty server that I need to access from both mac and PC clients. If the server has been rebooted, I can SSH into it, but I can not VNC into it unless I unlock the keychain. The problem is that I can't figure out how to unlock the keychain from SSH connections, so the only available method is to attach a keyboard to the physical box and enter the keychain password at the server itself.Is there a Terminal command that I can use to unlock the keychain? I have seen references to the 'security' command but that appears to be unavailable to Jaunty?
Is there an even better method than a Terminal command? I don't want to be putting passwords into the Terminal log if I can help it. Ideally, I would connect via SSH, confirm the keychain somehow, and tunnel in through VNC.

I just installed 10.10 on a desktop machine, dual boot with Win XP. Everything went well, it connected and did all the system updates etc. Then one time I rebooted and it wouldn't connect. I've tried rebooting again several times, tried unplugging the modem/router from the power and from the computer then reconnecting everything and starting it up again, no joy. I booted from the Live CD and it connects without any problem, likewise from Win XP. My Network Connections shows 'Auto eth0' and below is the ifconfig output.
Code:
jim@ubuntu:~$ ifconfig -a

I'm running Ubuntu 10.04 LTS. Last night I was doing some admin on this box, it's running apache and ASSP for spam filtering. Once I finished I started some updates.I checked for updates and applied them, but fell asleep. This morning, my session had timed out at continue. I reconnected and saw a message stating a reboot was required.I've rebooted, my usual services are running, eg apache and ASSP. I can view pages on apache and the admin page for ASSP. I'm remote from the system, so connecting over the internet and when I try to connect, it fails.
Quite urgent, however at least my services are working. However I'm not happy that I can't access the system myself.I don't know if this is my own fault for leaving updates unattended or if an update caused the problem. Thanks.

I running Ubuntu ver 9.04 I have 2 problems that I think are related. After finally making a network connection I updated Ubuntu, and after a reboot I lost my network connection again.I updated the following file nm-networkmanager-settings.conf and saved it. After another reboot I then lost my network connection icon and it also does not appear under System > Preferences. I tried to then update the same file and can not save it, I get "could not save file".I have tried sudoedit, sudo gedit, gksudo gedit and some others that I cna not remember now and all give me the same result

do not post such long blocks of messages directly on the forums. Attach the output as .txt or use a pasetebin.

I updated to the latest available kernel for Kubuntu 10.04 today (2.6.32-24). When the system rebooted, it refused to connect to my wireless network. So far I have been unsuccessful in persuading it to connect. ifconfig shows the existence of the ethernet connection as eth0, and Network Manager also seems to accept the existence of the ethernet port - so why has it suddenly chosen now to stop connecting to the wired network?

I was having an issue with my wireless connection last week, and sometimes even my hardwired connection. It had seemed like every time my PC went into standby, or any low-power mode, the WiFi would stop working. I used the "power off" command and got it back and running. When I boot up the computer in the morning, I am unable to connect until I reset the wireless router. Unfortunately, I did not have the presence of mind to get iwconfig first thing in the morning, but I did reboot the laptop and grabbed iwconfig before I connected and after I connected. Now, for some reason, the router worked when I rebooted, but I had to reset it this morning. Any ideas? iwconfig below:
****Before Connect****
jake@jake-laptop:~$ sudo iwconfig eth1
[sudo] password for jake:

I can get connected to the Internet when I reboot the system, but the connection usually fails after within 10 mins. However, even then the network manager says it's connected. Never reconnect, manually or automatically.

I have been using this fresh Debian 8.2 install for 3 days without any network problems.
What I did this morning :
- Booted in my windows partition and rebooted immediately just to remove the system from the sleep state
- Mounted a NTFS hard drive and copied some file to my .wine drive_c
Thats when I noticed that my connection was down.
I verified all the physical layer. My laptop has access to the internet tried to connect on an another router with eht0, changed the wire, nothing worked.
It seems like the interface can't get a dhcp ipv4 address even when I try to force is with dhclient, I get no offer when my laptop works just fine.
- Booted on my windows partition without changing any connection and my internet was working.
- Booted back on debian still not working...

I rebooted my vServer (Debian 8) and it doesn't came back up. Well, I used the rescue console on my server and the server seems to be running fine, except the network was broken. So I tried 'ifconfig' but nothing came up. So I tried to enable my interface with 'ifconfig venet0 up', and now it appears in my ifconfig list
Code: Select allroot@i67svof:/var/www# ifconfig
venet0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:36463 (35.6 KiB) TX bytes:0 (0.0 B)
My HWaddr doesn't look that well :) 'ip addr' prints this result:
Code: Select allroot@i67svof:/var/www# ip addr
1: lo: <LOOPBACK> mtu 65536 qdisc noop state DOWN
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: venet0: <BROADCAST,POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN
These are the last lines in /var/log/syslog:
Code: Select allroot@i67svof:/var/www# tail /var/log/syslog

I have my ubuntu box hard wired into my network. It all works fine, until I reboot my ubuntu box. After reboot, it can no longer see the network. I have it set up with a static ip. Not sure that I set it up completely correctly but it works fine...when working.. To fix the problem, I enter terminal: ifup eth0 That fixes all know problems until next reboot. What do I need to do so that it will remember settings and automatically be hooked into the network at power up?
