This is multiple benefits as well, you can. Need to learn more about tcpdump, so I'll start with this tutorial by Daniel Miessler.Įditor's note: This answer was referring to tinker's blogspot article which is meant for invited users only. This is typically the practice for making sure a process keeps running as a system process and avails a valid PID.Need to learn about Ubuntu logs for troubleshooting.Lsof -i |grep -v 'localhost' (list open files matching an Internet address of any, grep to remove any open files associated with localhost - my thought here being that I don't want to see local services as they likely will not affect network utilization). Netstat -cW (list network connections continuously in wide format so foreign addresses aren't truncated) So, I'm thinking I'd like to see all network connections and what they're doing. I've seen this on Windows boxes before, and 99% of the time it's spyware. ![]() Started up my Ubuntu 10.04 desktop this morning to find that after a few minutes the Internet connection is crawling. I went through the same learning curve on process identification.įrom my notes: Ubuntu box connection information So far, restarting the machine is the only way I found of getting rid of the issue.

The command iftop gives results that disagree entirely with the information reported by System Monitor. This will display the kernel buffer messages new messages will appear as they occur. At the command prompt in our new window session, we’ll launch dmesg and use the -H (human-readable) and -w (wait for new messages) options. Is there another command I can use to find out which process is getting out of hand? We type the following to start a screen session called monitor: screen -S monitor. I've found questions here about monitoring total bandwidth usage, but, as I mentioned, that's not what I need. Both the resource monitor and the top command only tell me my total network usage, neither of them tells me process specific network info. Problem is: I have no way of knowing which process is responsible for my high network usage. When it does, I just run a top command to find out which process is responsible and then kill it. This sometimes happens to me with the CPU usage. Sometimes while I'm working (I still don't know why), my network traffic goes up to 200 KB/s and stays that way, even tough I'm not doing anything internet-related. I think I'm being the victim of a bug here.
