From: David Kirkby on 24 Jul 2010 00:17 I wish to know of a system has a server running at port 8000, and if so what its called if possible. I know I can do $ telnet localhost 8000 but that hangs and one neds to use a control-C, Also, in general, it gives no information about that server, though there are exceptions. I suspect lsof can do this, but that is not a standard part of Solaris. (I want to get the information from a script which could be run on arbitrary Solairs/OpenSolairs hardware. Dave

If the port been opened "on all interfaces", it'll look like "*.8000" in the output. If it is just open on one interface (eg 1.2.3.4), it'll look like 1.2.3.4:8000 instead. I can't think of an easy way to work out what process has it open. The pfiles command can tell you if a given process is listening to a port, but you'd need to run it on each running pid... -- Chris |
