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

vanessa_socket_pipe
VANESSA_SOCKET_PIPE(1) General Commands Manual VANESSA_SOCKET_PIPE(1)
NAME
vanessa_socket_pipe - Trivial TCP/IP pipe based on libvanessa_socket
SYNOPSIS
vanessa_socket_pipe [options]
DESCRIPTION
A TCP/IP pipe is a user space programme that listens for TCP/IP connections on port on the local host and when a client connects makes a
connection to a TCP port, possibly on another host. Once both connections are established data sent on one connection is relayed to the
other, hence forming a bi-directional pipe.
Uses include enabling connections to specific ports on hosts behind a packet filter.
This code is intended primarily as an example of how many of the features of libvanessa_socket work.
OPTIONS
-c|--connection_limit:
Maximum number of connections to accept simultaneously. A value of zero sets no limit on the number of simultaneous connections.
(default 0)
-d|--debug:
Turn on verbose debuging to stderr.
-h|--help:
Display this message.
-L|--listen_port:
Port to listen on. (mandatory)
-l|--listen_host:
Address to listen on. May be a hostname or an IP address. If not defined then listen on all local addresses.
-n|--no_lookup:
Turn off lookup of hostnames and portnames. That is, hosts must be given as IP addresses and ports must be given as numbers.
-O|--outgoing_port:
Define a port to connect to. If not specified -l|--listen_port will be used.
-o|--outgoing_host:
Define host to connect to. May be a hostname or an IP address. (mandatory)
-q|--quiet:
Only log errors. Overriden by -d|--debug.
-t|--timeout:
Idle timeout in seconds. Value of zero sets infinite timeout. (default 1800)
Notes: Default value for binary flags is off.
-L|--listen_port and -o|--outgoing_host must be defined.
