in thread Telnet Client/Server: What am I doing wrong?

the previous post asked for working examples... it's difficult to cut out brief parts

Though it may be difficult, it's a good training exercise for you in learning Perl. The act of creating a small cut-down program should help you focus on and better understand the problem; you may even find you're able to identify the problem and fix it yourself.

BTW, instead of your global NS file handle and the:

select (NS); $|= 1; select (NS);
claptrap, you should use a lexical file handle ($ns say) and then simply:
use IO::Handle; # ... $ns->autoflush();
With recent Perls (5.8+), there's no need anymore to confusingly change the (global) default destination for print statements via the old evil one-argument form of select -- for more details, see Perl Best Practices, chapter 10 and Perl tip: Buffering and IO::Handle (for Perl 5.14+ you don't need use IO::Handle).

Suggest you further read Suffering from Buffering.

    Thank you for the feedback and document references!
    I'm going to continue to read the Lincoln Stein Book, will check out the Best Practices book as well.
    I have read the Suffering from Buffering! A good read, indeed :).

[atcroft]: james28909: Make both hands into fists, place them together (with thumbs concealed), and every knuckle is a month (starting with Jan.) has 31 days, every dip (between knuckles) does not....
[atcroft]: (And Feb. is the odd case, because it is 28, unless it is a year divisible by 4, or if it is divisible by both 100 and 400 (at which point it is 29).)
[james28909]: i know but scroll through your calendar on your computer.
[james28909]: i thiught you were going to say make both hands into a fist and puch yourself in the face
[atcroft]: .oO(Sorry, I probably should have said take two normal hands....)
[atcroft]: james28909: No, unless you are a politician, I wouldn't say that (and even if you are, I still probably wouldn't say that).
[james28909]: i mean how hard can it be? its just subtracting days lol
[atcroft]: james28909: What about October 5, 1582?
[stevieb]: atcroft: "Make both hands into fists..."... is something my Ma taught me in our native lang, but I was to ignorant and young to pay attention. Thanks for that :)
