I have Ubuntu 10.04 server edition which comes without any GUI.Some of the web applications are present on it.But the problem is from a past few days if I reboot then immediately after a reboot the server shows me a process polymouthd which takes 96% of CPU which makes my server damn slow is there a way to find out what is polymouthd doing in my server and how can I disable.

I've been using linux for a few months. Recently I have installed debian jessie and I'm learning how to secure my laptop. I have installed
Code: Select allapt-get install sysv-rc-conf
to shutdown few services that I believe I don't need at boot which I found very useful. Among others I have deselected avahi-daemon, cups, cups-browsed, etc. The problem is that, after rebooting, when running:
Code: Select allnetstat -lntup
I still find 'avahi-daemon: r' and 'cupsd' running. I have tried
Code: Select allsystemctl stop cups
systemctl disable cups
systemctl stop avahi-daemon
systemctl disable avahi-daemon
But after rebooting these services are aklways running. I do not know whta to do.
Output of netstat -lntup
Code: Select all[*]Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 127.0.0.1:631 0.0.0.0:* LISTEN 250/cupsd

I'm aware that cups seems to work just for my printer but I do not understand why I can't just disable it.
I'm trying to reboot the server (shutdown -r now).But it seems like nothing happened.
When I try "shutdown -c", the system prompts "shutdown: cannot find pid of running shutdown."
I have installed a cluster computer with 10 nodes . The manufacturer is HP . All nodes and the master node have redhat enterprise linux installed in them . When I shutdown the nodes from the master terminal using "shutdown -h now" they get shutdown . But they dont get completely turned off . This issue bothers me when the power supply is given , all nodes boot up simultaneously generating a huge heat .
Thing to note : When we shutdown our PC they get completely turned off . When the power supply is given , a press on the Power On button is required to boot the system. But , why does it not happpen in the case of cluster? Is there any other way of completely turning off the nodes from the master terminal ?
After upgrading from scratch to Ubuntu server 10.04 (previously 9.10), I noticed that my server was cast out of the Cheers bar , i.e., nobody knows its name anymore! (I have several Linux boxes on my home network).
Is there a new direction on how local networks are supposed to be configured? a new protocol? I know my problem is solved by simply installing avahi-daemon, but I wonder how other people are dealing with this issue.
i have been scratching my head and repeatedly banging it against a wall
i have a lan:
m0n0wall router
ubuntu server (headless/no mouse/kbd/speakers, etc in attic)
4 desktop pc's
1 dlink dsm 520
my server is exactly that it has mysql/apache/mediatomb/php/cacti/phpmyadmin/samba/nfs/mpd) ignore all other service running on server & focus on MPD. all 4 desktop pc can connect to mpd and they can see the library. BUT they cannot play any track as it states there was an error with the audio device!i have tried all the examples on the web and none work what do i do? how do i configure it to use the LOCAL soundcard NOT the one that is not present in my server? all the examples are set to use the LOCAL(one on machine running MPD) sound card which does not work until i connect a speaker to my server which again is located in my attic and only has a pc speaker so this is NOT what i want. all 4 desktops do not have mpd installed as they do not need it. all media is stored on my server the gui's that connect to mpd do not have any configuration for a sound card
I'm trying to modify an existing user so that any files they create can be at least read (although writing and execution would be nice) by any other user. The reason is because I need the daemon running my Apache server to be able to access files created by a daemon running under this user, files which will be created and accessed in real-time.

I installed the server and client, making sure to follow the instructions closely with all the certificates. The problem is the service daemon on the service won't even start.

I have a Redhat fedora core release 6 (2.6.22.9-61.Ns4) server and form time to time ssh fails although I am still able to ping the device and with a reboot the device will start working correctly so upon further investigation it appears the sshd daemon fails.Not knowing a great deal about Linux I thought I would ask some advice on the path I am thinking of taking. The first would be to put an entry in the cron to try and start the ssdh every hour or so. Would this cause issues in the long term run it multiple times when the sshd daemon was still running?
The Second though I had was having a bash script to check if the process was running and if not restarts it and if it was just exit the program which would seem like a neater way to do it but this is where my limited Linux knowledge hits a wall so was looking for suggestion on how to implement this?
My problem now is that lsyncd does not automatically start if the server reboots. I need lsyncd to start automatically also using the --delay 5 option.

On my virtual server I had the same issue within the last three month. The postfix daemon stopped working suddenly and I don't know why. I can restart postfix normally and it's working normally for a couple of weeks until the next crash. Does anyone have the same problems with CentOS 5.6 and postfix?
View 4 Replies View RelatedThe config file is ambiguous, and keeps getting overwritten when you restart the daemon in Debian, anyway.
In /etc/transmission-daemon/settings.json, there are these options:
rpc-username
rpc-password
proxy-auth-username
proxy-auth-password
Every time I restart the daemon with:
/etc/init.d/transmission-daemon restart
It overwrites rpc-password, and the password it prints doesn't work anyway.
Does anyone know how to set the password properly? I don't want to disable it.

I installed LAMPP a couple of weeks ago and was working fine. Today when I try to start lampp, it will only start MySql and ProFTPD. It says "XAMPP: Another web server daemon is already running." How can I find out where this other server is located and stop it?

I have a debian machine with an apache2 webserver. I am able to start the machine from the internet (power plug board with webinterface) but I don't know how to shutdown the server automatically if nobody uses the website anymore. It is a homeserver which should only run if needed.
Unfortunately I don't know much about Linux, apache, php, cgi-scripts, cronjobs and other things that might be useful. But I googled a lot and have now an idea how it could work. It seems complicated to me and so I want to ask you guys what you think about it and if perhaps you could give me a hint.
The idea: A cronjob starts every ten minutes a php script that checks when the index.html of the welcome-page was opened the last time (fileatime()). Lets say it was opened last time at 3pm. Then the php script adds for example 60 minutes to that time (=4pm) and calculates how much time is left to 4pm. This time is saved in the variable $timeleft. Now the php script compares if $timeleft is less then 10 minutes (=600 seconds). If it is, the php script starts a cgi script that will shutdown the server. The cgi script will login as root (I think that can be done with the "expect"-command url and then enter the command "shutdown -h now"
Is all this realizable? Isn't there a better and/or easier way to do?
