Reg process of killing

shanshine · #1 (**permalink**) 12-03-2007

Dear All,

I have one doubt - when u use netstat -na | grep 8080 to know the status of 8080 ports.when it is listed someone is accessing the 8080 ports
like this
*.8080 *.* 0 0 64000 0 LISTEN
172.19.69.39.8080 172.19.50.20.1929 65535 0 64260 0 ESTABLISHED

Please can anyone say how to kill the process of that particular ip who is accessing 8080 ports.

Appreciate if anyone helps me.

Regards,
Shanmuga

netstat won't show you which processes have those connections open but lsof does.
The commandline you'll probably want is

Code:

for pid in `lsof -i:8080 | grep '(ESTABLISHED)' | awk '{ print $2 }'` ; do kill $pid

Test it first though - wouldn't want to accidentally send a SIGTERM to the listening daemon

lsof -i:8080 on it's own should be very informative too

[edit]Oh, you want to target a given IP... I missed that bit on the first run through.
For a particular IP, replace the '(ESTABLISHED)' bit with '->172.19.50.20' (for example)

can i get lsof manual entry and patch

lsof isn't part of Solaris. You need to download it from freeware repositories or recompile it from the source.

Alternatively, you can use pfiles to figure out which process is using this port, eg:

Code:

pfiles `ptree | awk '{print $1}'` | egrep '^[0-9]|port:' | grep -v "AF_INET6"

pfiles can sometimes be a little hard on the system, I've seen it impact performance considerably. Might be better on later versions of solaris but it was pretty nasty on 8.

I believe pfiles is suspending the target process for a short period of time. Isn't lsof doing the same ?
