View 1 RepliesI'm pinging a certain website and what happens is that each time the ping process freezes for an unknown reason ca. 10-15 sec then it starts to ping. Note that only this particular domain causes this hanging and Ctrl-c seems to have no effect at all! The domain is niteco. So far I've tried several independent linux systems all with the same result however other non-linux systems ping normally.

I looked at 'top' for a while and didn't see anything obvious, but there's always stuff running there that I don't necessarily know about. Looking at 'processes' using 'system monitor', I found a zombie'd process called 'runbackschedule'. Could this be it?
If not, how would I find out what the issue is?
Maybe someone can shed some light on this process that is running. It is using my CPU about 100% since there are 2 instances of it running with about 50% used by each.abc_sieve_2.10_i686-pc-linux-gnuI've never noticed it running before and don't think I've installed anything except updates.
View 6 Replies View RelatedI am seeing an unknown internet connection both send and receive of about 5kbits that seems to happen every 15 seconds or so. I noticed this the other day and rebooted. It went away but I noticed it again. Nothing shows in the System monitor under processes. I can close all programs and it still seems to happen. What is the best way to track down what is causing this connection, and how to tell what it is connecting to?

I have the following problem. I want to find out connection between process and socket. When I type to the terminal the following command netstat -anpetu so I get the following output:
[Code]....
As you can see just some connection have assign PID/Programme. How can I find out Program of this socket without PID/programme. like this 0.0.0.0:52472? Certainly I know that some port are well-known but there are a lot of unknown ports(like 8307 3350 and so on).
My machine seems to be constantly downloading/uploading something. Not much - 1KiB/s - 50KiB/s, but it is bugging me.Is there a tool to see what process is using the network connection?

View 1 Replies View RelatedI have this problem for a month now. Some apache process that appears rather slowly using 100% cpu for each core. Today I watch some logs in apache2, namely other_vhosts_access.log and discover this

On 8181 I have google sitemap generator running but I have it for over a year and it never make any problems.
If I uncheck and recheck "Enable Networking" in the Network Manager Applet 0.7.996 I would expect the wired network to disconnect (which it does) and reconnect (which it does NOT). So I tried sudo ifdown eth0 and got

ifconfig tells me

so I am at a loss. How do I stop and restart the network interface short of rebooting the machine?
I tried posting this before and I'm not sure what happened but I don't think it worked, so if it did please forgive the double post.am very very new to centOS and linux in general. I just want to setup a test web server that more closely mirrors our actual web server that is hosted by rackspace. I've installed centOS and tried to setup Apache, PHP and MySQL from a guide on the web using Yum. When I go to localhost in the web browser I'm able to see the default apache page. However when I create a php page it's just blank.When I look at the apache error logs I get this: PHP Warning: Unknown: failed to open stream: Permission denied in Unknown on line 0
I've been searching alot on the internet and I know the issue is permission related, but I don't know how to fix it. I've seen some forum posts that say you need to use the chmod 775 command on the /var/www/html folder.Currently when I do ls -l /var/www/html it returns
-rw------- 1 root root 19 May 5 13:16 index.php
-rw------- 1 root root 19 May 5 13:15 index.php~
I'm sure that this isn't correct but like I said I don't know much about how to set permissions or who the owner needs to be. I've done alot of searching and seen similar posts, but no one seems to explain it clearly.
I am using ubuntu 9.10 and I still cannot figure out this thing. I work behind a proxy managed by my university. Now, I cannot ping the other users on my network although they can ping me. Not to mention, I also cannot ping [URL]... It says : ping: unknown host [URL]... But I can ping the proxy server.

I wasn't downloading anything big, I have just opened Firefox, Thunderbird etc. It stopped after a minute but I'd like to know, what that was - this wasn't the first time something like this happened.

#It will try to use mac2 as the file to look in which won't exist

I'm trying to create a PAN (Personal Area Network) using a laptop (Siragon ML-1040) and my desktop computer, but I get the Connection Refused (111) error.
Blueman doesn't detect any network service between the two computers unless I start PAND on one of them and then it detects the NAP service. That, only after I enable the NAP/Workgroup services on the Services submenu in Blueman. However, it doesn't work neither with the NM plugins or without them (dhclient and that other one I can't remember the name of).
Any clues over here? I'm using pand 4.91 and blueman.

I'm trying to do a SSH connection between my home and work PC both machines are running ubuntu 10.04. I have read all the comunity documentation at [URL] from Work PC. I went on to the web site what is my ip address and noted down the number, From Home i opened a terminal and typed: pnig (ip address). to which their was no reply, now i'm assuming i need to configure the works router to except connection requests, is this Correct?
Also what information do i need from my works network and how do i get it? I understand that I need the routers expernal ip address, but how do i referiance a specified computer after that address? What program do i use in ubunu and how is that information applied to it?
My problem is exactly the same as [URL]
but I am stuck at the last hurdle
here are the output of the command that helped to solve the case in the previous post:

When I have video running and the video stops, I see that the connection is destroyed in about 5 seconds, which is what I want. If, rather than stopping the video, I pull the plug, I have seen it take 350 and 380 seconds before the connection is destroyed. Why is there such a large difference in the time to destroy a video connection between stopping the video and pulling the plug on it when using net filter connection tracking? How can I shorten the time for the connection to get destroyed when pulling the plug?
View 3 Replies View RelatedI have two linux laptops. Currently, I'm using both of them at work, side-by-side. Now the problem is, I'm connected to a wireless router, but the wireless only works on one of the laptops. So I'm stuck with one laptop that has no access to the internet. Both machines do, however, have working ethernet nic cards. So, I was wondering if I could use the laptop with the wireless connection to share the internet connection with my other linux machine and access the internet on both of them. Or as an alternative, just use the internet on the machine without wireless and be able to switch back and forth, that would increase my productivity like 30 fold.
