i have a web server, nas server sitting in the corner of my room and just upgraded to lucid via ssh and it is quite strange that ubuntu server wont start unless a monitor is plugged in and i really don't want a monitor sitting in the corner
View 9 RepliesI've got a headless server (32 bit 9.04/9.10, can't remember) that started refusing SSH and HTTP connections a few days ago, and I'm just getting around to hopefully fixing it. The problem is that I can't even connect to the darn thing. I've plugged in a mouse, keyboard, and monitor, but the monitor tells me that it has no signal. I know the monitor works with the computer, as I used the same one to set up the server.
Just for kicks, I even tried to put in a live CD, but that didn't help. Any ideas on how I can connect to this thing?

Say,you have 200 linux servers and you want to monitor things like, disk activity, disk usage, CPU usage, various logs of the servers. What tool is best recommended for this system administration purpose ?
View 3 Replies View RelatedI just installed ubuntu 9.10 server edition (twice, just to be sure) and the installation ran fine, but when I try to boot into the system, i get past the BIOS loading screen then my monitor just goes into power saving mode and I can't get it to see a signal from the PC. I know the OS is running, because I can ssh into it from my laptop, and I know the monitor works, because that machine had a windows OS on it before and that worked fine with the same monitor. I had thought it might be a graphics card thing with ubuntu trying to push out at a resolution not supported by the monitor, but I find that unlikely as it's brand new this month. If anyone has any idea of something I can try to diagnose the problem, that would be great. As I said, I still have ssh access to the PC, so I can basically try anything on it that I could if I was physically at the box itself.

When rebooting, the server now turns the monitor off, and I'm not sure if anything's loading. I see the initial dell splash screen, and hear the hard drive start to run, and then the monitor goes into standby.
I have a number of computers on a LAN. There are 3 laptops and 1 desktop, all running windows. I also have a Ubuntu server in the garage which servers up files to all those on the LAN. The server is not visible outside of the LAN for security reasons. Now, I want to track all traffic from any computer in my house that is coming and going in and out from the inter-tubes. I do not want to add this as a service to my current server as (a) it is behind the LAN and (b) I don't want to mess with security issues with that server.
I think I could set up a computer (an extra) which is between the modem and the router with two ethernet cards which would be able to monitor all traffic coming and going. This computer would, obviously, be exposed to all potential attacks as it wouldn't be behind the router's firewall. I'm not sure exactly how that would like or what software to use.

View 6 Replies View RelatedI have an ubuntu server installed on an old computer (Its a Pentium 4) and it was running fine for a while but ever since I installed the JDK (x11-common was a dependency) the system starts fine but I'm unable to connect to it through ssh unless a monitor was plugged into the computer. I also am unable to ping it, meaning its no longer connected.
Also, if I leave it running for a while it the same thing happens (ping returns destination not found). Anyone knows how can I fix this?
I don't know if this is useful but the server is connected to a wireless network that uses a WPA2 key.
What is the setup required in order for a 2 NIC machine to only forward traffic ?
I am planning to set up a machine between the LAN and Router like this:
LAN <--> machine <--> router <--> internet
This machine will only forward traffic. I will use it with ntop, squid, maybe snort
or maybe Untangle if I find it satisfactory.
Is my scenario fiable ?
I want to forward traffic, use ntop and squid on it.
I have installed Ubuntu KK server, and when I turn on my machine without monitor, after 5-7 min - system stop and not responding on all my requests (network, keyboard.). With enabled monitor all work good.

View 9 Replies View RelatedI've installed Ubuntu Server on an old computer and I want it to autoboot as it is intended to be a headless box.I have installed the desktop packages to allow me to use FreeNX.URL]Unfortunately I've already made these changes and it still seems to need a monitor before it will show the boot menu and a keyboard to press enter on the first option.If I restart from within the gnome desktop, it will reboot perfectly. If I use shutdown -r now, shutdown -s now or shutdown -h now and then power it on again, it will display the GRUB boot menu without automatically booting.
View 5 Replies View RelatedInstalled server 10.04 using an old Sony 19" multi scan 400ps CRT monitor. The command line font is less than 1/8" high: something on the order of a large 4pt or small 5pt font. Made several attempts to locate the correct info using the man functions and searching the archives, but so far have not been unable to find the needed information. The eye strain is about to make me eligible for a white cane with a red tip.
View 4 Replies View RelatedI've recently decided to make a foray into the world of servers without any knowledge or experience. Yesterday, I ordered a Dell t110. I understand this is a really low-end server but I think it will work for home use. I am on a budget and literally just ordered the box. No keyboard. No mouse. No monitor. Not even an additional hard drive! With the exception of SLIGHTLY upgrading the processor, the thing is basically stock.
My question is this: Can I control and operate this server with my laptop somehow? Will that allow me to install Ubuntu Server as well as perform systems administration tasks? Ultimately, I'd like to get a new flat screen for the living room and have that be the monitor, with a wireless keyboard and mouse. However, like I said... I'm on a budget. I don't think I can sell my wife on that one right away. So... in the meantime, I need a way to actually USE my server.
I just installed Ubuntu server on one of my computers, but when I boot up the screen goes blank and the monitor gives me an 'Out of Range' error. I understand that this means that the resolution settings are too large for the monitor, but I don't understand how to change them, since there is no GUI installed. Details:
Monitor:
LCD
Recommended Resolution is 1280x1024
I have also tried it on another monitor with a recommended resolution of 1920x1080, This also gave me an OOR error. Ubuntu Server version 11.04
Is there something which can act as a fully fledged proxy (exactly like squid) but which can also monitor data usage?
At the moment what I do is I log data usage of IP addresses (allocated by DHCP) by using IPFM. Obviously getting a new IP address from a DHCP server isn't hard and this could be abused.
So I was thinking if I require proxy authentication and log usage that way, there is no way for anyone to abuse the system.
Does anyone know of a proxy server capable of logging data usage?
I've installed an Ubuntu GNU/Linux 10.04 Server (Lucid Lynx) in a great computer, but with a small and old CRT monitor, that doesn't support much screen resolutions and frequencies. How can I do to make the system to use everytime traditional text mode (80x25 characters or compatibles)?
View 3 Replies View RelatedLast night I was able to set up my server so that I can just connect vnc. I even was able to be connected at the log on screen so I could select which user I wanted to log in at. For some reason today, I have to have the monitor plugged in all the until the logon screen comes up before vnc will connect. Once the logon screen is up, I then can connect via vnc & select which user I want to logon as. It's odd because it worked last nigh, but today - Nope nada, it doesn't work & I can't explain why. I did clean up - Removing some applications I don't need on my server. (I'm hoping that isn't the problem) It's odd as well because I don't have to be logged on as a user to connect via vnc, I just have to wait until the logon screen is available...Then I can unplugged the monitor & logon.

View 4 Replies View RelatedI have an embedded server running Ubuntu which is on a network with a lot of wireless AP's. The AP's doesn't support SNMP or anything else, so I monitor if they are up or down by simply pinging them continuously.
My question is if there is anything I could install on the server that could provide me with a webpage where I could see the ping time to the AP's? So it just shows a list of the IP's I have told it to ping, and what their latest response time is. This is what I basically need, but if it were more advanced than that, and could give warnings if ping time were to high etc.
I'm trying to set up and run Monit to monitor an Apache2 webserver, I want to be able to ensure Apache is running and if it's not have it restarted with an email alert sent out.
The monitrc (edited for relevance) looks like:
Code:
check system *server name*
if loadavg (1min) > 4 then alert
if loadavg (5min) > 2 then alert

I posted this in the Networking section, but should probably be over here. Couldn't move it. I have a transparent proxy in place. I have Webmin installed on the server. Is there an app that can monitor bandwidth in real time? Also run reports? I have SARG installed, but seems to only monitor HTTP traffic, I need to monitor all traffic. I have a bridged connection, but monitoring the outside interface is fine too.
View 5 Replies View RelatedI'm installing a server to act as a firewall between a local network and internet. I've installed Firestarter becaused it worked straitgh away (it seems that FS is configuring the routing as well). I've tried to remove it, and then I lost the access from LAN to Internet. (I don't know why -perhaps the routing is disabled then- , so I prefer to keep it).
The problem is that Webmin Bandwidth Monitor (bandwidthd) is not logging anything when FS is active. Does someone has an idea on how I could make it work? I've tried cacti and some other stuff, but it is far too complicated for me.
I would like to monitor a RedHat via snmp. I would like to make available data via snmp. The data that I would like to graph are only present in logs file. Is it possible to parse data from applicative logs and have them available for my cacti server via snmp? I already monitor CPU, mem, and others with cacti using the standard MIB.What would be the logical step I would need to achieve that?
