Nonprivileged ports on solaris
Is there a way to change a privileged TCP port (say 80) to a nonprivileged one..
# 2

I believe that Solaris will only let you adjust the range, not specify on a per port basis. You can see the smallest (default 1024) using:

ndd -get /dev/tcp tcp_smallest_nonpriv_port

You can change it using:

ndd -set /dev/tcp tcp_smallest_nonpriv_port some#

I found a nice treatise on the subject at:

http://www.ncftpd.com/ncftpd/doc/misc/ephemeral_ports.html#Solaris

Cheers,

I have already tried to use ndd to set the smallest non privileged port, but it wont accept any thing below 1024.

From Sunsolve:
Quote:
In Solaris, the available range of TCP/IP ports is 0 to 65535. However, there are some restrictions that apply:

Ports in the range 0 to 1023 are reserved for privileged (root) services, such as telnetd, ftpd, and so on.

Ports in the range 1024 to tcp_smallest_anon_port-1 are used for user services such as NFS server daemon, FONT server, and so on.
This leaves the range 32768 to 65535 available for general TCP/IP connections. To limit the range of the port numbers allocated for the general use, the following two ndd(1M) parameters can be used:
tcp_smallest_anon_port:
This determines the smallest TCP port number that may be used for an anonymous connection. Solaris allocates anonymous ports above 32768. The default value is 32768.


tcp_largest_anon_port:
This is the largest TCP port number that may be used for anonymous connections. The default value of this is 65535.
You mention port 80 - are you trying to change where http will be going? If so, you can change to port inside (example Apache) the httpd.conf. If not, give more information on what you are trying to accomplish.

sssow,

Maybe you should elaborate on the problem you are trying to solve, rather than the solution you are trying to use. Why do you want to have port 80 be non-privliged?

Sorry for not giving much details..We were trying to install Iplanet webserver as a non root user and it wont let us use standard port 80 as it is privileged one. I could install it with a different port like 8080.

If you want to install I-planet as a non-root user, you need to specify a port above 1024.
