I've done some searching around but can't find anything conclusive on this error. The tech at my remote site restarted the 9.04 server(not sure if it was accidental or planned) and when it started the boot process, an error like the following shows up...
"The display server has restarted 6 times in the past 90 seconds. This indicates that something bad is happening."
I have the Samba server & users configured, I can access between Linux/Windows shares and both SMB & NMB services are set to be enabled at boot.Everything working.But when I restart the computer, I notice in services configuration that "This service is dead." for NMB. Therefore I have to enable it manually upon boot so that it works.I'm using Fedora 10, fresh installed and updated. I've noticed through search that others have had this issue as well throughout other versions of Fedora, yet I have not found a conclusive solution to this.
View 3 Replies View RelatedThis little guide is for anyone with an HP Touchsmart Tm2 series running Ubuntu 10.04 and above. PLEASE NOTE: These workarounds, solutions, and tips have been tested and verified to work on an HP Touchsmart Tm2-2050us running Ubuntu 10.04 Lucid Lynx and Ubuntu 10.10 Maverick Meerkat. Installation: There are no problems I have experienced with installation except for the display not working on the live USB/CD images occasionally, this can be fixed by simply closing the display lid, and reopening it (this usually has to be done at least 2 or 3 times). Display: Most times after boot up, the display is black. A workaround for this is closing the lid and reopening it (repeat until the display works). Another reported solution is as follows:
1) Open a terminal
2) Type:
Code:
sudo nano /etc/rc.local 3) Add this to the bottom of the file (this disables the ATI part of the hybrid graphics card):
Code:
echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
4) Press CTRL-X (to exit), Y (to save changes), and ENTER/RETURN to accept the file name.
5) Reboot
Note: This solution is also reported to increase battery life.
Trackpad: It may seem that the right click button is disabled, but it isn't. To right click, you must tap the very bottom right corner of the trackpad. Also, by default the trackpad does not have multi-touch enabled (even though it is capable of it). A reported solution for this is:
1) Open a terminal
2) Type:
Code:
sudo nano /etc/X11/xorg.conf.d/50-two-finger-scroll-touchsmart-tm2.conf
3) Add this to the bottom of the file:
Code:
Section "InputClass"
Identifier "enable synaptics SHMConfig"
MatchIsTouchpad "on"

Is there any way to tell who or what process rebooted a RHEL server?
Somehow one of my boxes got restarted this morning, i'm trying to figure out who/what did it.
I'm setting up a mythTV frontend, so have set up automatic login in GDM, which works perfectly. I've also re-enabled the "kill X server" key combo (ctrl-alt-backspace), as other people here are used to that to restart it if everything goes pear-shaped.
However, the autologin isn't working properly after I kill the X server -- just sits at the login screen, and I have to manually log in.
how to fix that? Essentially, I never want to see the log in screen -- I want it to always log in as my generic MythTV user.
Not sure if it's any help, but here's my /etc/gdm/custom.conf:
Code:
[daemon]
AutomaticLoginEnable=true
AutomaticLogin=generic
TimedLoginEnable=false
TimedLogin=generic
TimedLoginDelay=1
DefaultSession=gnome
(I've also tried enabling the "TimedLoginEnable", and have tried delays of 0, 1, and 10 seconds. They don't seem to work, either.)
I have been running squid3 proxy on a Ubuntu 10.04 machine for several months with no problems.It serves about 50 users ( win and Lin clients ) and is usually rock solid.
However, over the last few days problems occur.
The users lose connection and I have to restart squid and all is ok again. Sometimes it drops 4-5 times in an hour ans sometimes not for 6 hours or more. I know the problem is related to Squid as the actual internet connection is on and the squid machine can access the internet.
Restarting squid cures the problem.
How can I troubleshoot this ?
Checking the cache.log doesn't show anything strange as far as I can see.
Could it be that the cache file is full or something ?

Is there a way to select a second installed OS on a home server system without display and keyboard? I am putting together a home server (for mail, storage, media streaming) using an Atom-based Ubuntu Server 10.04 on a 4 GB intern flash drive and 2 hard drives for data storage, but no display or keyboard. I want to make periodic full backups of the system (flash) disk and use a second OS (installed on a partition on the hard drive) with a graphical interface (e.g. Xbuntu or PartImage) for maintenance purposes. I can connect remotely (from a Win7 or a Linux computer) to the X-display once the second system is running.
a) how can the second OS be booted on this server without keyboard? Is there a way to tell Grub2 to look at some hardware switch (or file) for the menu selection? The board has a serial and parallel port so I could wire up a switch to some pin of one of these. Also external USB connectors are available on front and back. Or can Grub2 read its default OS choise from some simple file, easily to change from a shell command of the eBox webbased system control internface?
b) I assume the second OS is needed to make a complete backup of the server OS on the flash disk. Can the backup be automated? (i.e. switch to second OS, backup, reboot first OS)
I sshed to a server a week ago, then ran *screen* and created a few windows in my screen session. I then ran a few programs on those screens. All the programs were running in the background (I run them with &). I did not close or detach from the screen sessions. So I was still connected to those screen sessions from my client machine.
Then, this morning I find my client machine rebooted. When I do screen -ls I find there are no screens available to reattach to. But that is not the worst part. The strange thing is that all my processes (which were running on the server) have disappeared as well, even though they were running in the background. I thought 1) using screen I will be able to re-attach to old screens when my client restarts, 2) If I have sshed to a server and have run programs in the background, restarting the client should not stop those programs (even if I had not used screen).
trying to set up a very minimal X on my 10.04 64 bit version of Ubuntu running nothing but Open SSH and acting as a firewall/router, making a PPP connection. The reason, is that I want to set up KVM/Qemu and run a virtual machine. The virtual machine will have a graphical environment and will be connected to my TV so that I can watch movies, stream TV etc. using it. So far, I have done the following:
sudo apt-get install xserver-xorg xserver-xorg-core miwm
When I try to run miwm the error message is:
(null): can't open display.
I have no DISPLAY variable set, but even when I set one myself using export DISPLAY=:0.0 it makes no difference.
I am noticing really odd behaviour after upgrading from 8.10 to 9.10 (via 9.04). My server frequently becomes unreachable. I am using it as an application server, running Apache, JBoss and MySql. Once the server goes idle, all web connections time out. SSH also times out. Usually the server wakes up on second SSH attempt and then everything: Web, SSH etc seems to run fine.
This is a server machine with no GUI. Can anyone point me to power management or other such settings I can tune from commandline? I have disabled power management by adding kernel parameter acpi=off. I still have the problem. The first network connection after the machine has gone idle takes a long time. All later connections run pretty smoothly.
At work, we use two very powerful servers to host a series of VMs to do some heavy-lifting analytical work. Part of my job has been to evaluate a variety of different virtualization environments, including changing the host OS (or dom0 kernel for Xen), changing the platform (KVM, Xen, ESXI, etc.), and changing the guest OS types.
I noticed a number of behaviors that Ubuntu exhibited that set it apart (almost always in a positive way) from the other OSes. Most astounding though was that when an Ubuntu 10.04 AMD64 server VM was booted from an Ubuntu 10.04 AMD64 server host (that is, same version of Host OS and Guest OS) in KVM, the guest boots in roughly 2 seconds. At least, the guest boots faster than the VNC connection can initialize.
I'm certainly not complaining, but I can't for the life of me figure out how this could be possible. I understand that the Upstart init daemon is very good about startup times.
When ever i run ssh -p <port> <user>@<remote IP>, i get a connection has timed out error. (i use the -p <port> part because i'm using a custom port). does anyone know what could be causing this? i know of a few *possible* problems, but i don't know how to test them all.
- I am on the same network as the server (I'm trying to test using remote IP to make sure it works before i go out an try it somewhere else)
-The router could be blocking it (i'm using linksys)
-IPtables may not be set up right (i think it is though. the only thing i've run is "sudo iptables -A INPUT -p tcp --dport ssh -j ACCEPT". I have changed the port for the server since then. maybe i have to restart it or something for it to recognise the change? I know very little about IPtables though).
-maybe i have to change something in my client or server config files? (the only config file i've changed is the sshd_config file on the seerver, and that was to change the port to my custom port).
thats all i can think of for now. It may be none of those. I do have the sshd_config and port forwarding in my router set to the same port, so thats good.
I 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 changed over to U-Verse which means I have a new router, gateway and IPs. Took some doing but everything is working on my server with one exception.Outgoing SMTP mail.I get CONNECTION TIMEOUT when ever something from inside my network tries to hit an SMTP server outside.Any computer within my network does a Telnet (hostname or IP) 25 and I get a time out.Port 25 is open on the router.

Even when I connect to my server over LAN, Firefox times out occasionally while connecting. I can't figure out what is causing this. The error_log isn't showing anything. I even cleaned the error_log file, so that if something happened, it'd be a little easier to spot. But I'm still getting time outs, and nothing in the error_log.
Here is my httpd.conf [URL]
It's the default Fedora configuration, I've only changed the ServerName if I remember correctly. it's not the Timeout setting, because on LAN it should never time out.

I have a server with 8GIG of ram and a quad-core q9550 CPU and 500GIG of hard-disk space, and 100Mbps net connection.I have separated it into 3 parts of 2 Gigs of ram each, by virtualization, so there are 3 VPSes. The problem is that the one of the VPSes (created) with centos and WHM/cpanel would go down very often, as many as 60 times per day!I asked one of my friends to have a look at it, and he told me that Tomcat was the reason.Things got a little better (ask me what I changed about Tomcat?!) and after that the server would go down only about 20 to 30 times per day.I asked the friend again, and he told me that the CPanel integrated antivirus would cause the high load periodically.(Ask me again, what did I change?) And after that the server would go down only about 4 to 10 times per day.Now, as far as I can tell, there is nothing more that would/should cause the server to go down.
About 30 minutes ago, before writing this post, the hosted sites were unavailable again, for about 30 seconds.I checked the load through ssh and I saw that the load is 3, so I went to the main server and checked the VPS ram and noticed that only 10% of the cpu is used and only 307Mb of available RAM is used.
Everything shows that the server should be functioning OK, but it still seems to get unavailable far too often.
I used the top command and noticed that there is nothing using the cpu and the ram and all of them are 0.I used the mysqladmin proc command and again nothing noticeably weird seemed obvious at this time. I also checked the other VPSes and they were also in relatively low-resource-consumption states(I don't understand this part):Also sometimes I use the top command when the load goes high I see that all of the users, even the non visitors users site use cpu seems forexample a refreshing things or updating thing updates all of the accounts forexample mysql or so Please help me to figure out what other things might be causing these service/server high loads and unavailability.

View 7 Replies View RelatedI have an Ubuntu 11.04 Server set up for my small office whose sole job is to run as a samba file server. The problem is that it randomly hangs. For example, I can connect the clients just fine, however if left idle it tends to take a few moments to work when you try to go back into the shared folder or drive. The client will behave like it is disconnected and is trying to search for the drive only to a few moments later, go right back to normal behavior.
If I ping this server while this is happening my requests will time out for a little while and then just start working. The same thing happens when I try to connect with Putty or through WebMin. One second its unreachable then the next its fine.I have already tried swapping out patch cables (which actually seemed to work for about 2 weeks) and I have patched it to an alternate port on the switch. The only thing I have not done at this time is to change the NIC.All the clients are running Win7 with the exception of two XP machines.Simply put, its like the machine just goes dormant for a while until you ping at it for a while to wake it back up.
Is it possible to get file modification times measured to less than a second?milisecond, nanosecond, 10th of a second.

I run a CentOS 5.1 using VMServer on XP. From home I can successfully 'cvs login' to my CVS server. But starting 'cvs update', the connection times out.

Can I assume that it is not a port/firewall issue, since "cvs login" is successful? Any clues where to start diggin'?
