wget only supports http and ftp protocols.
From what I understand, you want to check if each service listens to his port?
What about:
Code:
$ nmap -p[port] ip.ad.dr.ess | grep [port]

?
It outputs (with ftp service for example):
Code:
# invoke-rc.d vsftpd stop
Stopping FTP server: vsftpd.
$ nmap -p21 127.0.0.1 | grep '21'
21/tcp closed ftp

# invoke-rc.d vsftpd start
Starting FTP server: vsftpd.
$ nmap -p21 127.0.0.1 | grep '21'
21/tcp open  ftp

NAME
simpleftp - Rudimentary FTP client SYNOPSIS
simpleftp url [...] DESCRIPTION
simpleftp is a Perl script that provides basic support for fetching files with FTP in a batch oriented fashion. It takes one or more FTP URLs on the command line. The file(s) will be retrieved from the remote server and placed in the current directory with the same basename as on the remote; e.g., <ftp://ftp.isc.org/pub/usenet/CONFIG/active.gz> is stored as active.gz in the current directory. The script properly understands usernames, passwords and ports specified as follows: ftp://user:password@host:port/path/file BUGS
simpleftp is an extremely poor substitute for more complete programs like the freely available wget or ncftp utilities. It was written only to provide elementary support in INN for non-interactive fetching of the files in <ftp://ftp.isc.org/pub/pgpcontrol/> or <ftp://ftp.isc.org/pub/usenet/CONFIG/> without requiring administrators to install yet another package. Its shortcomings as a general purpose program are too numerous to mention, but one that stands out is that downloaded files by simpleftp override existing files with the same name in the local directory.
