I am not an advanced Linux user. I have a VPS with 768MB of RAM running CentOS.I executed the lsof command as root and I see that there is a list of 3000 files. Usually, how many files should be there? My system is getting very slow, so is this list too long?How do I know which files to keep and which to close?I have seen that there are multiple copies of the same files with different PIDs. There are many log files in the list that I have not opened. Is this normal?total used free shared buffers cachedMem: 104287 492 103794 0 0 0

No noise is produced. What's going on?

I'm running a native dual-stack (ipv4 & ipv6) dsl connection.So, I've been adding firewall rules, cleaning up unwanted processes, etc to tighten security.I'm left with only 3 processes that are listening to ports. mysql, ipp & ssh.Still not quite sure I need mysql. I run Amarok but without using a database, so I don't actually use sql for anything that I'm aware of.Anyway, my question is;Is it possible to make any any of these processes listen to ipv4 only or ipv6 only? Is there a distinction there at all?
Example- ssh is currently listening to port 22 on both tcp & tcp6. I do all my ssh connections using 'ssh -6', so, Can I make ssh listen to tcp6 only, or ignore tcp ?
When I do netstat -pantu it shows a dash where the pid would be. I have also checked lsof -i and see no pid associated with the port. How do I find what program is keeping the port open?

However, I would like to be able to hear it all the time. I don't want to have to record to be able to hear it. Is there a way to mix the line input sound with the normal system sounds? This is so I can run sound from my Xbox 360 into my computer. I currently use a audio splitter but I get problems with volume levels due to voltage changes going to the speakers.

I am implementing an IPC mechanism using message queues (Sys V).I can receive the messages using msgrcv() function. I am wondering how can I listen on the new messages.

I run various manual checks on my system to see if there's anything I can't account for and just one such instance just got thrown up here. I reproduce the output from netstat below. I see there is something called "microsoft-ds" shown as listening. What on earth is this doing on my PCLinuxOS box? I have googled it and there does appear to be some security issues related to it for Windows users and all the advice relating to it that I could find is for Windows users, but I am just baffled as to what this is doing on my Linux system.

I am using ubuntu 8.04 with firefox browser.
There are some sites which allow you to listen the mp3 song like [url]
I have found the most simple way to get mp3 file
(1)Sometimes you get address ending with .mp3 so just copy the whole URI and use in terminal wget "PasteWhatYouCopied"
(2)But in the link I have mentioned there is no mp3 link in address bar.
Here I found out in totem-plugin-viewer(that is the thing that plays your file in browser).Just Click the button next to sound and select copy
In example taken above it is [url]
And use just like before wget "PasteWhatYouCopied" -O output.wma
Also notice that you have the song as output.wma in current folder of terminal.
(3)If there is a video on webpage then either wait for it to get completely downloaded & get it from /tmp.Remember don't close the page till video gets downloaded completely & you copied it from /tmp then only close that tab.
(4)There is a firefox addon 'unplug' which can help for flv because after sending file to download via unplug you can close that tab.

I have an audio source that I want to listen to through my PC speakers. My computer has both a mic(rophone) and a line-in audio connector. I am able to use the "gnome-sound-recorder 2.28.1" under Karmic Koala to record from these sources and then I can play back the sound.
However, I'm more interested in listening to the audio then recording. Though, recording would be nice if it where available too. Using Rhythembox Music Player, Movie Player and Audacious2 I am able to play CD(s), Pod Cast feeds, Files and possibly other sources I'm not seeing anything to handle hard wired input to my sound card as an option.
Do I need to open a device as a source? Do I need an extension to one of these players?
i am using ubuntu10.04 , the sound is distorted booth on playing cds or listening to radio online . it sounds like a record where the speed keeps changing

Now most guides I find for this problem just say to un comment the line in the master.cf that says "smtp inet n - - - - smtpd", the problem is that line is already uncommented and I am still not able to telnet to port 25 from any machine on my network.

I have Lenovo T61 with opensuse 11.4 which until this morning was working just fine. I have used OpenSuse on this notebook for about 2 years with out much trouble. This morning on boot up I could not login because GDM was not listening to the keyboard for some reason. I rebooted on a live disk and the hardware was just fine. I switched to init 3 in /etc/inittab and the keyboard was working fine. If I started X with startx it still worked fine. If I started gdm the keyboard was not working anymore, so much so that I could not do {ctrl}{alt}{F1} to switch to a virtual terminal or {ctrl}{alt}{bksp} to kill X, nothing. The mouse worked so I could reboot.
I installed KDM and switched to it instead of GDM for the display manager with yast and was able to login and everything is fine. I would like to switch back to GDM but it is not that big of a deal
I'm trying to execute X server (automatically), which will not bind to 0.0.0.0 (port 6000) - meaning X server will not listen on generic interface. If it's possible, I'd prefer X server not to listen at all (and communicate through other IPC if needed), is there a way to make it not listening at all? -nolisten flag or something like that? (and do it automatically, every reboot). Also, Is there a way to make X server bind to 127.0.0.1(localhost) instead of 0.0.0.0(generic interface)? It should be in one of the configuration files or the start-up command to run X.

What is the problem I have a local server
CentOS Linux
In my sshd_config file I have the following
Code:
Does this mean that all of my network interfaces are listening as opposed to just one specific network interface? Would 0.0.0.0 include 127.0.0.1?
Also, this computer(A) is on a LAN at my house. It has two network interfaces(eth0 & eth1), both on different subnets. I can connect from another computer(B) on my LAN to this one on one interface(eth0) via SSH just fine. The other interface(eth1) on this computer is hooked up to it's own gateway to the internet using DSL. I'm using this interface(eth1) for running bind.
Anyhow, here's my issue. When using a computer(C), which is a hosted VM , from outside my LAN, to connect to computer(A) via SSH, I get connection refused. So I checked my hosts.deny & hosts.allow files, both empty. I run nmap from computer C and SSH comes up as closed. So I'm thinking it's a firewall issue.
Here's what my iptables -L looks like:
Code:
I've been meaning to learn more about iptables, but which chain is for which network interface? I have also tried running nmap from computer(C) to test bind out on tcp 53 that comes up closed. I run udp 53 and that comes up as closed but then again udp is funny because it's stateless. If I run netcat on udp port 53 from computer C I get a blank line as if it's still running. However, I get that for all other ports anyways so that's of no use.
Unless my AT&T DSL is blocking those ports. But if that were the case would the error 'Connection refused' come up when I try to connect via SSH?
What other tests can I run to troubleshoot?
