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

FTP Multiple-Line Text Replies

It is possible for a reply to contain more than one line of text. In this case, each line starts with the reply code, and all lines but the last have a hyphen between the reply code and the reply text, to indicate that the reply continues. The last line has a space between the reply code and reply text, just like a single-line reply. This facility is often used to provide additional response information after a user logs in, via the 230 reply code. Table 231 contains an example.


Table 231: FTP Multiple-Line Text Reply Example

230-Welcome user to FTP server jabberwockynocky.
230-
230-You are user #17 of 100 simultaneous users allowed.
230-
230-
230-Please see the file "faq.txt" for help using this server.
230-
230 Logged in.


As mentioned before, the actual text string for each reply code is implementation-specific. You can sometimes find some rather humorous text strings associated with some of these error messages. For example, I tried some commands using the FreeBSD FTP client on one of my Internet accounts. If you try to send or receive a file before you are logged in, it doesn't return an error like “Requested action not taken. File unavailable”. It tells me “Login first, then I might let you do that.”. Laugh… what an attitude these computers have today! J
