Please Whitelist This Site?

I know everyone hates ads. But please understand that I am providing premium content for free that takes hundreds of hours of time to research and write. I don't want to go to a pay-only model like some sites, but when more and more people block ads, I end up working for free. And I have a family to support, just like you. :)

If you like The TCP/IP Guide, please consider the download version. It's priced very economically and you can read all of it in a convenient format without ads.

If you want to use this site for free, I'd be grateful if you could add the site to the whitelist for Adblock. To do so, just open the Adblock menu and select "Disable on tcpipguide.com". Or go to the Tools menu and select "Adblock Plus Preferences...". Then click "Add Filter..." at the bottom, and add this string: "@@||tcpipguide.com^$document". Then just click OK.

Thanks for your understanding!

Sincerely, Charles Kozierok

UNIX netstat Universal Options and Parameters

Most of the options shown in these option groups are particular to those groups; for example, you cannot use “-s” when issuing the command “netstat -i”. However, there are also a number of universal options that can be used with more than one of these groups to modify the behavior of netstat variations in a consistent way. These options are described in Table 297.


Table 297: Typical UNIX netstat Universal Options and Parameters

Option / Parameters

Description

-f <family>

Limits the output of the command to information on a particular protocol address family, for hosts running multiple protocol suites. For example, the address family for regular TCP/IP is “inet”, while for IPv6 it is “inet6”. Others may also be supported.

-p <protocol>

Restricts output to data related only to a particular protocol, such as IP, TCP, UDP, or ICMP.

-n

Shows network addresses in numeric form, instead of showing them as symbolic names. Also shows ports as numbers instead of converting well-known UDP and TCP port numbers to the protocol names that use them (for example, “23” rather than “telnet”).

-W

Suppresses the automatic truncation of addresses (which is sometimes done for display formatting).
