Hi,
Got an old applications trying to use ports 800 and 801 in Solaris. However these are restricted/reserved for root usage. Are there any configuration work arounds for either un-reserving the ports or to re-route this apps traffic thru a normal usage port?
Any advice?
- L.
ndd -set /dev/tcp tcp_smallest_nonpriv_port 800
This has the unfortunate side effect of making 802-1024 non-priviledged as well.Unfortunately, this is the only way I can see to "remove" a port number from being priviledged. You can add ports as priviledged individually - but you simply can't make individual ports unpriviledged.

Hi swoneill,
I have tried your suggestion on Solaris 9, but I always get the following result:
START --
# ndd -set /dev/tcp tcp_smallest_nonpriv_port 700
operation failed, Invalid argument
# ndd -set /dev/tcp tcp_smallest_nonpriv_port 1025
# ndd -set /dev/tcp tcp_smallest_nonpriv_port 2000
END --
It seems that I can reduce the privileged port but only increase it. Any idea?
Thanks in advance.
