General :: Disable Ssh Server Permanently?
Mar 7, 2011
Now i want to disable my ssh server "permanently",which means it won't run unless i start it after i login.that is,it is disabled at boot time by default.
i have asked a similar question before,but i still have some confusions.
Say that now the ssh server is running.my system is ubuntu 10.04. code...
The disable|enable API is not stable and might change in the future.
the shell gives me a warning:do not match LSB Default-Start values,this API is not stable and ...
what does this mean? still it can't disable the server "permanently",ethier.
what on earth should i do to solve this?

So I just installed Ubuntu on my second laptop, however I ran into a problem. The F9 key is going crazy. I'm not exactly sure what is causing it (I've already popped off and cleaned the keys) but if I could find a way to just disable it I'd be very happy.

I came across the following method of how to permanently disabling selinux and it's notifications. Although changing enforcement from the gui into permissive mode does most of the job, the notifications still pop-up when some applications are started.
So to disable it do the following:
open terminal as root and execute:
Quote:
And then change the SELINUX line to SELINUX=disabled
Quote:
This is it. Now reboot the system and selinux will never bother you again.
If you are not a Fedora user and you are using this forum just because we are cooler here then you will not find the /etc/selinux/config as in the fedora releases. What you need to do is to edit the kernel boot line and add selinux=0 at the end:

Reboot the system

I am using Ubuntu 10.04 on Lenovo Thinkpad, and I have tree pointing devices:
- touchpad
- trackpoint
- mouse, that is connected only when I am home, so for around 50% of time.
I have downloaded a package "Pointing Devices" and tried to disable a touchpad, which annoys me. Sometimes new settings works, but each time I connect/disconnect mouse, the default settings (everything on) restores. It's even worse, because right now the touchpad works and annoys me, while it's written that it's disabled in "Pointing devices", so either the package is outdated, or it's a BUG.
How to permanently disable a touchpad?

I've tried all three options here to permanently disable the fn key (so that when I press F1 it'll bring up help and when I press fn+F1, it'll dim the screen, etc.).
These methods work upon reboot, but once the computer is put to sleep (i.e. I close my lid), the settings are reverted back to default and I must use fn+ for everything again.
How can I keep the fn key disabled?
And on another note, why use gksudo instead of just sudo?

I don't use wireless on my desktop so i would like it permanently disabled...each time i boot up it's back and receving up to 80mb of data from an unknown connection via wireless (i dont use wireless) so, to avoid any weird connections to my neighboors house or some kid hacking the neighborhood driving by with a wireless router in his truck i'd like to permanently turn off wireless. this is kind of funny because i had a hard time getting wireless to work on my laptop, but this is my desktop where i do not want it. i looked it up and your forum back in 2007 said to type in iwconfig in the shell then get the nickname of the wireless card then to black list the wireless card. i did this but it didn't work, so what do i do now? i have ubuntu 9.10

What's the best way to permanently disable the package kit update applet in fedora 12. i really dislike my bandwidth being robbed unnecessarily from the other computers running fedora on the network.
System->Preferences->System->Software Updates is not working as it is supposed to.
What is the role of PackageKit? Do i really need it?

How to permanently disable the gnome-keyring-daemon.
I've seen posts where there was a work around to store passwords in clear text. That's not a real solution. I've seen posts where killing the process and removing ~/.gnome2/keyrings is a temporary solution until next time you log in or reboot machine. Removing the package, will force removal of the whole kitchen sink. That's too intrusive.
There must be a way to stop this thing from starting up, ever.
I tried commenting out the entries in the /etc/pam.d/* files that refer to "pam_gnome_keyring.so", and have also unchecked the 3 keyring related entries under System --> Preferences --> Startup Applications, which are affiliated with these 3 files:
But I still get this one process once I log into the console window:
There must be one more file somewhere that says, "hey when someone logs in and starts up gdm, start the gnome keyring daemon".

I have compiled the proprietary nvidia drivers for 11.3. When I boot, even using the nomodeset boot option, the nouveau module still loads, causing gdm/X to fail. I am able to manually remove the modules with rmmod and restart gdm. Everything then works normally. I have added the line "blacklist nouveau" to both 50-blacklist.conf and 99-local.conf in /etc/modprobe.d

I got this problem where my USB ports don't work. So if I do the command:
modprobe -r ehci_hcd
it fixes it. I can put it in the /etc/rc.local so that it runs every time when the server reboots. But, I want the ehci module removed without ever being loaded because sometimes the server goes through an fsck and the module is loaded and therefore I cannot use my IPMI to access the server.
I believe that my kernel has it within it because blacklisting the module does not work. I've tried remaking the initrd with this:
add module to /etc/modprobe.d/blacklist
mkinitrd -f /boot/initrd-$(uname-r).img $(uname -r)
and that didn't work. I've searched on how to do it but nothing is really clear. I would like to know what the command would be to do this. I use Fedora 8.
I would like the ehci_hcd module to not be loaded so that if the server goes through an fsck, the module is still not loaded.

I am failing to set PATH for all the users on a linux box(Fedora 8), permanently. Basically, I have installed two different versions of python(2.5 & 2.7) Python2.5 path is /usr/bin and it is set by default for all users(not by me, also i don't know how ) and it is working fine.
Python2.7 path is /usr/bin/Python27/bin, so tried this:
PATH=$PATH:/usr/bin/Python27/bin
And it worked only for that particular session and for only root, as I set path from root user. So, i need this to be set for all the users on the linux box, including root, more importantly as permanent. So if any user types "python27" at the command prompt, it should give python2.7 prompt.

I run my own home server using OpenSuse 11.1, everything is setup using apache, php, etc etc, and it all works perfect, but now I need to use my own email server for the use of Dolphin social networking software, so that when someone registers, the email server sends out registration confirmation emails, so I set up postfix, yeah right!!!, even though I followed all instructions to set postfix as a closed relay, a test done at mxtoolbox site still said it was an open relay, but while I was trying to set up postfix, my access to the server slowed down, and my servers drive light was constantly active,,, so when I look at the mail queue, I saw 4000+ emails, all from japan, (hinen.net), so I promptly shut down postfix and use postsuper -d ALL in the command console to delete the queue, but no matter how I try, I couldn't configure postfix as a closed relay,,, so I uninstalled it and installed sendmail, and using webmin, I could use a spam list and block the domain, now, sendmail's test at mxtools show as a closed relay, I can't even send out a test email using smtp auth, but disabling auth, I can, but now my IP is blocked at spam cop, and spamhaus,,, gmail server say my IP is not authorized to send to their servers, but to use my ISP relay instead,,, but my ISP doesn't have a relay,,hence the need to run my own email server.
My home server uses double layer firewall, a hardware firewall between the internet and the server, and a software firewall on the server, and I only allow the ports I need, IE, 80 = http, 443 = https, 20/21 = ftp, 25 = smtp, 110 = pop3. and that's all, but any other internal access from my workstation to the server, using ssh, I only open the ports on the server firewall. If someone here has a great deal of knowledge on sendmail, and can set up a an M4 (linux.mc) config file for me, it would be much appreciated. What I would like my email server to do, is to only allow the sending of emails from inside it's own server system,, ie, when a php script sends an email to the server, then the email server would let it through, but anything else, outside the local network is ignored.

Newbie here! Our website CMS is a Tomcat webapp, which runs on a CentOS 5.6 release (Final). The webapp needs a permanent increase of the max. open files value. Currently, the site is "crashing" frequently due to continuous "Too many open files" exceptions that eventually will occur when traffic increases.
This is what I've done to try to increase the max. open files value code...
But still, when I log in (as any user, incl. root), ulimit -n shows 1024, not 16384. Am I missing something here? And, more importantly; Will Tomcat be able to open > 1024 files after my changes mentioned above?
(PS: I also tried rebooting, but no difference.)

I just bought a 31.5" HDTV and have it connected to my laptop as a monitor. My laptop monitor is cracked and pretty much useless so I would like to be able to keep it turned off and stick with my new monitor. So far, I have managed to accomplish all of this, just one problem, I will need to go through too long a process for every login to set it all up again. I'm hoping someone can help me simplify this and have everything done automatically while Ubuntu is booting or even right after login.
Process:
Code:
$ cvt 1366 768 60
# 1368x768 59.88 Hz (CVT) hsync: 47.79 kHz; pclk: 85.25 MHz
Modeline "1368x768_60.00" 85.25 1368 1440 1576 1784 768 771 781 798 -hsync +vsync

I play MAME in Ubuntu 9.10 and every time i boot my PC I calibrate my joystick with jscal. The correction values are stored in a script ( /etc/joystick.cal ) but when I reboot, the old values are written again in so I have either to repeat calibration or open the script and give the right correction values (which I have stored somewhere). So , what is the way to save my changes in this script permanently ?
