open ports solaris 8
Hello,
I have a number of Solaris 8 Sun servers that have open ports that I cannot identify. I see some with 1012-1020 (which are reserved ports according to the IANA. Lsof does not identify these. One server has all these on and one server just has 1017.
*.1023 Idle
*.1022 Idle
*.1021 Idle
*.1020 Idle
*.1019 Idle
*.1018 Idle
*.1017 Idle
*.1016 Idle
*.1015 Idle
*.1014 Idle
*.1013 Idle
I also have Disksuite running on 2 of the servers and I see strange ports opened by inetd. Some research indicates that this could be from a Disksuite metatool, but it isn't on all the servers.
# *lsof -i :36724*
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
inetd 247 root 13u IPv4 0x30004c18638 0t0 TCP *:36724 (LISTEN)
# *lsof -i :36725*
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
inetd 247 root 14u IPv4 0x30004c184b8 0t0 TCP *:36725 (LISTEN)
# *lsof -i :50689*
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
inetd 210 root 13u IPv4 0x30001a2be38 0t0 TCP *:50689 (LISTEN)
# *lsof -i :50690*
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
inetd 210 root 14u IPv4 0x30001a2b3b8 0t0 TCP *:50690 (LISTEN)
But then I have another server which isn't running Disksuite that has a similar port open.
# *lsof -i :32769*
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
smcboot 265 root 3u IPv4 0x300001470b0 0t0 TCP *:32769 (LISTEN)
Any ideas please?
Thanks

BUGS
The network synchronization between client and server instances is weak, and does not prevent incompatible options from being used on the
two instances. The method used for retrieving work completions is not strictly correct, and race conditions may cause failures on some
systems.
