unix program that can port scan a c block of ips for proxies
can anyone tell me a unix program that can port scan a c block of ips for proxies? a fast one, with reliable results, that can load an ip list, or set an ip range, and specify ports
thanks!
I need to format port scan output for input into another app.
This is what I have;
1025/tcp
1521/tcp
2301/tcp
2381/tcp
3191/tcp
3389/tcp
5938/tcp
47001/tcp
54321/tcp
21/tcp
80/tcp
135/tcp
139/tcp
445/tcp
1025/tcp (4 Replies)

Can any one please let me know below ones
1) How to Perform the Port Scan in Solaris Environment and how to block the unwanted Ports.
2) How to know whether particular Port is listning the requests or not?
Thanks

VDAAERL(1) Voicetronix Telephony Tools VDAAERL(1)NAME
vdaaerl - Measure the echo-return loss on Voicetronix FXO telephony modules
SYNOPSIS
vdaaerl [options]
DESCRIPTION
The vdaaerl utility tests the echo-return from a telephone line connected to a Voicetronix FXO module, such as those used on the OpenPCI
range of cards. It can scan all available impedance values to find the best match for a particular line.
It will wait for an incoming call on the port under test. The calling handset should have the microphone well muted for the duration of
the test.
A series of tones will be played down the line to determine the ERL in several parts of the audio spectrum. You should avoid creating any
other noise on the line while this test is running, or the results may be skewed.
If no --impedance is specified, and the --scan option is not used, then the default impedance value (based on the port's country selection)
will be used.
OPTIONS
The following options are available:
--help, -?
Show summary of options.
--card number
Explicitly select the card to test. Default is card 0.
--port number
Explicitly select the port to test. Default is port 0 of the card being tested.
--impedance number
Test a particular impedance setting [0 - 15].
--scan Test all available impedances.
--playgain db
Set the hardware play gain. Values may range from -12.0 to 12.0.
--recgain db
Set the hardware record gain. Values may range from -12.0 to 12.0.
