Garbage in "host" list with 25+ entries

Post by giulio »

I created a custom.zip with an helpdest.txt containing 50 [HOST] entries. Uploaded to the online builder (v.1.0).

The .exe I got back seems to be working but starting at entry 25/26 there's garbage in the entry list (maybe buffer overflow in some text strings), like

==========
entry1
entry2
...
entry26led to connect to listening VNC viewer
entry27
entry28
entry29nt user are unavailable at present
entry30
entry31ugin detected...
...
entry49Warning
==============

I get the "ugin detected" garbage even in one of the [TEXTTOP] section if it's very long

I have the same problem with the offline builder.

Is there a solution for this?

Thanks

I get the same thing. Guess you're the first to ever want more than ~30 connections, eh? lol

But yes, I agree it's probably a buffer overflow of some sorts. Mine actually adds some garbage on almost every line.

As you see, there's some "-plugin" and other random stuff plugged in all over the place.

Anyway, I hate to ask, but why on earth do you need so many connections anyway? But yeah, good work on the bug find lol =)

Oh the limit is 20-25 hosts limit.. The code will only support that many entries...

I wanted to use 50 entries because, even though there are only 4/5 people that need to receive SC connections, the local network is setup with DHCP and these 4/5 people can receive 1 random IP address in a range of 50.

The idea was for the support person to look what IP address he got and tell the remote end "use entry xyx" where xyz was the last IP address octet (10.0.0.xyz).

So, I assume from Bevtech's answer that there's no hope?

I would definitely use repeater instead of doing this. Give one machine a static IP, then set up around 10 ID numbers that connect to repeater. Much much easier. =)

What kind of a connection are you going to run these 50 entries on?? Mostly after 5-10 the bandwith is maxed. If you have more then 10 connections running at once you may see problems be caused by bandwith limitations..;)

I am fairly sure that the repeater has the same limit on it as does single click

I'd thought about repeater but I was esitant due to the fact that it seems it's Windows only, and the only machines we have always up and running are Linux; the Windows workstations are at the mercy of their users, and there's no guarantee a single machine will always be up; we have no Win server systems.

But now I just found in the archives a post with the sourcecode for Linux, so I'll try that.

Thanks!

I'm not entirely sure, but I think EchoVNC might be cross-platform. You might check into that. That's about all I can think of.

other alternativ solutions:
for who don't like ID number but prefer a familiar name like "home", "office"
for who don't want understand lost time of the reverse connection of SC

They could use open source software trough echoserver relay with UltraVNC at both side

I just came into a set up that someone else did. I have the same 25 host limit problem. Has this been resolved in a newer version? We have a support team and it's nice to assign a tech a particular number to always use. We won't ever have more than maybe 6 concurrent connections but if each tech connects to the same number all the time, it's clean and easy to keep track of. Unless there is another way to do it?
