hi all
1) how to determine available ports in a box (solaris)
do i have to go for a netstat on all the ports?
2) how to block a particular port for a particular type of connection.
Any help would be greatly appreciated
Thanks (7 Replies)
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.

just a quick question:
a. whats the simplest command to check open port and the corresponding services?
example:
bash-2.05# netstat -an | grep LISTEN
*.199 *.* 0 0 49152 0 LISTEN
*.8989 *.* 0 0 49152 ... (1 Reply)

Hi. I need to add code to my KSH script to automatically assign an open port number from a pre-defined range to an Oracle listener.
Should I use:
lsof -i
or
netstat -vatn
or something else?
Thanks. (9 Replies)

Description
The serial line controller provides four ports, with modem control on two of the ports. The DECstation 3100 and DECstation 2100 only pro-
vide partial modem control. The DECstation 5000 provides full modem control. The ports are used as follows:
Port Usage
0 Graphics device keyboard at 4800 BPS
1 Mouse or tablet at 4800 BPS
2 Communications port 1 (w/modem control)/local terminal
3 Communications port 2 (w/modem control)/local terminal
Each communication port from the serial line controller behaves as described in and can be set to run at any of 16 speeds. For the encod-
ing, see
When a graphics device is not being used as the system console, communications port 2 becomes the system console. In this configuration,
the port can only be used at 9600 BPS and no modem control is supported.
The serial line driver operates in interrupt-per-character mode (all pending characters are flushed from the silo on each interrupt).
Restrictions
Speed must be set to 9600 BPS on the console port and 4800 BPS on ports used by graphics devices. The serial line driver enforces this
restriction; that is, changing speeds with the command may not always work on these ports.
