General :: How To Purge Connections Left Open By SSH ProxyCommand
Apr 6, 2011I have a webserver WWW1 and a front-facing proxy PRX. I use SSH ProxyCommand to connect to WWW1's internal IP (private IP) via PRX (private+public IP). For some connections (not all) I see a network connection left open after I'm finished. These add up!
~/.ssh/config
Host *
ServerAliveInterval 5
ControlMaster auto
[code]....
On PRX, lsof | grep WWW1:ssh shows 124 open connections at the moment. On WWW1, the same command shows 243 open connections. There are similar open connections for WWW2, WWW3 etc.
WWW1 and PRX are Debian. Client connections are coming from a mix of Debian, Ubuntu and OSX10.6. I use Emacs Tramp but this has no special configuration (AFAIK) outside of my ~/.ssh/config. I'm concerned about running out of internal ports, and ideally I want these connections to clean themselves up without intervention. Ideally by configuring them to kill themselves off; failing that a command I can kill old processes with is fine!

View 2 Replies View RelatedDebian :: Gvfsd-http Leaves Many Connections Open
Feb 22, 2011Looking at the results of both `lsof | grep IPv4` and `netstat -tp` I noticed that I have a lot of connections open from a program called 'gvfsd-http'.
Using google, I found that this was a Filesystem something from Gnome, that would also be used If I drag something from my browser to my desktop.
Though I wonder, how I activated it, because I didn't do that...
After a bit of searching, I noticed that `screenshots.debian.net` uses the same IP address as the one noted (hades.car.gr).
PING screenshots.debian.net (78.46.20.5) 56(84) bytes of data.
64 bytes from hades.car.gr (78.46.20.5): icmp_req=1 ttl=56 time=55.4 ms
Question: Do I have some tool enabled that maybe sends statistics to debian or so? Where to find it and kill it.

Sep 6, 2010After contracting malware on Vista i decided to switch over to Linux and chose to start of with Ubuntu because of the graphical interface. that being said, you have no doubt inferred that i have no coding experience. basically i was hoping to find some nice tutorials and sites for Ubuntu. Also, i did downloaded the suggested programs and patches but im still experiencing problems with Adobe,flash, and and opening .exe files. for the latter, when i click on .exe files it is equivalent of using explorer on windows so i was wondering how to use the command prompt to open them. supposedly linux is susceptible to malware so if you could please suggest a anti -malware program.
