sockstat and unix sockets

[antolap]

Hi
How to see which processes are connected to which listening processes?

for example:
process A (connected processes: x, y, z..)
process B (no connected process)

Is it possible?

Doesn't sockstat do that by default?
Anyway...

man sockstat

says:

-u          Show AF_LOCAL (UNIX) sockets.

If neither -c or -l is specified, sockstat will list both listening and connected sockets.

Hope that helps

I'd like to see the associations among clients and server

I'm not really sure what you mean, but sockstat will tell you the name of the unix process that's listening - server? - and the IP address of a remote machine that's connected - client? - e.g. for IPv4 on port 443

% sockstat -p 443 -s -4
USER     COMMAND    PID   FD PROTO  LOCAL ADDRESS         FOREIGN ADDRESS       PATH STATE   CONN STATE 
www      nginx      97042 3  tcp4   192.168.1.87:443      192.168.1.64:60910                 ESTABLISHED
www      nginx      97042 8  tcp4   *:443                 *:*                                LISTEN

Maybe with fstat(1) from base system or lsof(8) from sysutils/lsof can tell you the process that has opened the socket file, check the -U parameter in lsof
