I've installed Ubuntu Server 9.10 on a small VIA C7 pc. Every now and then (it can take days or hours) the server goes to sleep. It can't be reached by network. If I hit the keyboard it comes to life within a second.I've looked in the bios and I cannot find any option that would prevent this. I used to run Debian Lenny on the same machine and never experienced the problem.

I don't know what to do, YaST always seems like it'll time out but eventually it reaches the internet. Can anyone give me some diagnostic commands to see what is slowing down the network on the server I'm running?
I can't connect to imap or smtp ports remotely.
Edit: I left out one thing, this is a mail server and a web server. Both are not currently being used as this is a fresh install of OpenSuSE
All other devices work fine with dig. Its just the server.
I'm trying to make the power manager NOT automatically shutdown / sleep / hibernate when battery power of my laptop reaches critical
I am surprised there isnt an 'NO ACTION' option for that in power manager
I've tried editing the acpi-supper in /etc/default bu couldn't find a solution in there nor in the /home/user/.gconf/apps/gnome-power-manager/ directory
I have 2 different networks :the first one is gateway machine (eth0), and the second is a private machine (eth1). So, I've configured the iptables and forwarding stuff and when I try to ping [url]..... on the gateway machine, it works, while it doesn't work on the private network. Note: I am using VmWare 7, CentOS 5.
I could say that the problem in DNS:because when I use this command in the private network machine: [url]...., it says connection timed out; no servers could be reached ,while in the public one, it works properly.....
I have standalone Suse 10 SP3 that when I run
Code: # hostname webserver but when I run host command
Code: # host webserver;; connection timed out; no servers could be reached I would like to get the IP when I issue

i have configured dns but error always appear server could not be reached .my ip add 192.168.10.2 and files are named.conf,192.168.10.zone and server.home.com(hostname)and home.com.zone

The problem is this;My system sleeps quite well, I can resume from sleep and get back to the desktop. However. the one thing that doesn't resume is > networking.I can disable> re-enable networking from the NM-applet and it tries again to connect but won't.I can sudo /etc/init.d/ networking restart, which essentially is the same as above. No connectionI've run ifconfig, and the connection is there but no address. Has this bug not been solved? Is it just a driver issue with my particular network card?It's the realtek 8201, part of the VT8237 chipset.Does anyone know what to do about this? I've been avoiding sleep mode on this computer for a very long time because of this bug.

The Question: Why won't my damned Ubuntu server just stay connected to the network?
i have just installed the 10.04 LTS server on my system.I set up a file server for my windows computers and can connect to the server. However, I was going to update and install a couple of packages, but My system cannot find the update or download server for itIs anyone else experiencing this problem. If not, any ideas on how to fix it.

I have a server on my home network. It's currently running a DNS server (bind9) and an HTTP caching server (squid).What I would like to do is redirect all outgoing port 80 connections to the squid server and also make the server responsible for managing DHCP on the network.
Do I just need to install a DHCP daemon on the server, disable it on the router, then set my server as the default gateway and configure iptables to route all connections like I want? Or is it more complicated than that? Also, would that mean that all communication between two computers on the network will go through the server?
I had problems with my Ubuntu Server 10.4, so I reformatted and reinstalled (I only choose OpenSSH from the install menu), then after it rebooted I installed apache. So I can access the machine via web, ssh and scp from within my local network, but strangely outside my network I can access it from web, but not ssh or scp. Nothing has changed on my router.

View 9 Replies View RelatedI am trying to setup a DNS server on my local network. When I set linux clients to use it, it works as expected. However, when I set windows clients to it, the root name doesn't resolve. For example, I have a zone called daniel. On linux "anything.daniel" resolves to the correct ip as does "daniel" which is the behavior I want. However, on windows 7, "anything.daniel" resolves correctly, but "daniel" doesn't. I am new to BIND9 so my config is mostly copy and pasted. Here is my zone file for daniel (where #.#.#.# is the ip I want daniel to resolve to):

I'm running Debian testing. I am running the iwlwifi driver and I have an Intel Centrino Wireless-N 1000 card. I have a fresh install of iwlwifi and network-manager. After sleep or after being shutdown, network manager cannot find my network's SSID. I have to wait ~5 minutes for it list my SSID. I dual boot this laptop with Windows 7, and on Windows, I connect to the internet instantly after boot. I did not have this issue before, the only thing I have changed was installing blueman and the necessary components. After I installed and uninstalled these bluetooth components, I have been getting these problems. Here are some outputs:

I am looking for some advice on how best to lock down our office network to keep our employee's from wasting time on sites like facebook and ...... This will be my first time setting up a server as a gateway in a production environment so I thought I should get some suggestions on what the best packages would be to do this.
I essentially need to lock down our network so that i can monitor what everyone is doing on the Internet and block it if needed. it doesn't have to be web based or have a bunch of gui's, im fine with command line, configs and log files, but it would be nice.
I'm interested in commercial products as well as long as they are linux based.
I'm trying to setup a NAS for my network, the only problem is that I can't figure out how to do it. On my network I have about 3 computers however only I only use 2 of them so I thought that maybe I could use the third computer in such a way that I could access it 24/7 from the internet as a server for all of my files (school papers, music etc etc...). The only problem is that I don't know where to get started. Both of the computers I'm currently using are Windows and the one that I,hopefully, can turn into a server is running on Ubuntu.
View 4 Replies View RelatedI am sure there is a nice guide out there somewhere but I cannot find it. My question is: The company I work for has a fully windows environment, servers and clients. The current server is on a Windows 2000 Server and I plan on replacing that. I wish to use Ubuntu server with Joomla for this purpose. This is my first venture into a purely command line interface, although I have played around with Ubuntu desktop in the past. My first question right now is: How do I log onto the Windows Network (active directory) from the ubuntu server. eth0 is reporting a valid internal IP on the network, so its been picked up okay.
Edit: I also want to assign a static internal IP address instead of grabbing from the DHCP. Edit2: Thinking about it, as the ubuntu server and windows server can ping each other do I even need to log into the domain? The server will only be serving web pages.
"Sleep" is not supposed to permanently kill off the network service. restarting the NetworkManager / network services DOES NOT WORK. Why this blatent and crippling bug is allowed tp persist? I dont want to "rasberry reboot" like windows, this has been the only forced reboot

I have two ubuntu boxes. One is a 9.04 desktop edition and the other is a 9.10 server edition I am working on some code that needs to be highly tolerant of bad network connections. It sends transactions to a central database, but when the network is not available, it caches them locally to retry later.
I have the code working beautifully on my desktop box. but when I test it on this other box (the one running server edition) there is a HUGE DELAY every time it tries and fails to send a transaction to the database when the network is down.
I tested a little further, and I found that if i unplug my network cable and run ping somehost on the desktop, it fails instantly saying "ping: unknown host somehost" But if I unplug the cable on the server box and run the same ping command it lingers for about 40 seconds before the ping fails.
Does anybody have any idea why this might be happening? Is this a 9.04 vs 9.10 difference? Is this a desktop vs server difference? Is there some package I can install, or some config setting I can change that will make the server box insta-fail just like the desktop does?
I have a good grasp on windows server 2003 but I don?t want to pay outrageous license fees for software and services and clients. I am newish to terminal as I only know a few commands. I have no problem installing services for the server edition for 10.04. Its just understanding whats going wrong to troubleshoot. I guess there is you guys and I have good working knowledge of Cisco's IOS's so I understand things like routing tables and interfaces and such for troubleshooting.
Questions I have... Can I install the desktop version of 10.04 and just install the server services? I was looking at the server guide [URL] and would like to know if these can all be installed on the desktop edition without too much trouble. I would imagine one could just use the server edition but I would really want a graphical user environment for some of the activities, if not all that I can. This would be becuase on my skills in the CLI. I priced out a server from Dell. I fits my budget perfectly if I go the Ubuntu 10.04 route. I was wondering if anyone sees any conflicts with the hardware for the Ubuntu OS....
