OK I've now received a couple of responses that make it appear I haven't
properly explained this. One implies I don't know how to use lsof
which I DO and the other implies the port is not active which it IS and
also implies that /dev/udp doesn't exist which it DOES.
So I figure I'll cut and paste what I see:
netstat -an |grep 2049
(IPs obfuscated with xx)
tcp 0 0 *.2049 *.*
LISTEN
tcp 0 0 10.0.xx.xx.2049 10.0.xx.xx.599
ESTABLISHED
tcp 0 0 10.0.xx.xx.2049 10.0.xx.xx.607
ESTABLISHED

ESTABLISHED
udp 0 0 *.2049 *.*
udp 0 0 *.2049 *.*
udp 0 0 *.2049 *.*
udp 0 0 *.2049 *.*
lsof -i :2049
Shows nothing
lsof |grep 2049:
lsof |grep 2049
bptm 28172 root 11u CHR 203,0x1f3100 0t0 2049
/dev/sctl/c31t3l1
(This has nothing to do with nfsd - just showing that nowhere in lsof
does it see PORT 2049).
lsof |grep nfsd
(We're running 16 nfsd's as this is a filesystem that gets shared out to
almost every other server.)

And finally:
ls -l /dev/udp
crw-rw-rw- 1 root root 72 0x000016 Oct 6 17:17 /dev/udp
Note sure what the -> stuff in above output is - it appears to me it is
showing some sort of link to the port which is why I questioned this in
original email. Also what is an "STR" filehandle?

Subject: [HPADM] lsof doesn't show nfsd? - what is /dev/udp?
OK - Just asking for curiosity. We were trying to install a SW package
that requested a range of ports and gave it a range that included 2049.
It failed because 2049 is apparently in use by nfsd. We found this in
"netstat -an" and then found 2049 in /etc/services.
However if I run:
lsof -i :2049
It finds nothing. It should have shown me the process (nfsd) that had
this port open.
If I run:
lsof |grep nfsd
It finds no sockets but does show entries such as:
nfsd 7776 root 4u STR 22,0x800c3 0t0 84
/dev/udp->nfsm->udpm->ip
So I'm assuming it is somehow using the /dev/udp to open the port.
My question is why wouldn't it show me 2049 in lsof? How would I know a
port was open on this /dev/udp and moreover how would I know what was
using it? Is there something that would tell me this if it weren't
defined in /etc/services like nfsd?
