TCP client/server with multi-connect in one script

[subzerostig]

NEW VERSION:

Hey guys, this is a TCP script I have been working on that supports multi-connect on the server side so no need to run 2 scripts at once.

The script allows you to send messages to each other. There is the function to remote shutdown and logoff, but I have added a security passcode.

The passcode is: systemmodal4096

Either download or copy and paste the script

Note: attempting to connect to the server from the application that started the server will cause the script to mess up.

I hope you like it

Excess code trimmed

[JohnOne]

Is there a particular reason the same code is repeated over and over?

[subzerostig]

oh dear it appears my laptop got copy and pasted more than once.

For some reason, the edit button has gone. Do you know why?

subzerostig,

You do not have enough posts to get the "Edit" button - I will do it for you.

Edit: Done - please confirm that I have not deleted too much!

[Melba23]

matwachich,

Are you suggesting that this code is plagiarising yours?

If you are just pointing people to your own version then please do not do it again. Your own thread lives or dies by its own merits - hijacking someone else's is not on.

[subzerostig]

Thanks melba23. How many posts do I need in order to get the "Edit" button?

[Melba23]

subzerostig,

I think it is 5 - but do not quote me and it is too difficult to get into the server to find out!

M23

[subzerostig]

it is too difficult to get into the server to find out!

yeah it is 5

[Melba23]

subzerostig,

Thanks for the confirmation!

[matwachich]

No no no! it's not this! Juste to say that by using this, his script could be (perhaps) improved and simplified.

I should told this in that post. sorry

[subzerostig]

Thanks Scriptmaster

I am going to release a new version with a new gui and many more goodies!

Thanks Scriptmaster

Sorry I deleted my post by accident.

Thanks for the code, my question is that this works only when the server and client are one single PC. what if the server was another pc?

I will be grateful to hear from you Guys.

Hi,

You have to change the IP Addresses. For the sender you set the "external" IP of the receiver, and for this last you set its local IP (mainly 192.168.X.X)

Br, FireFox.
