Halflife: 2 players with 1 name

[mi0epro]

The image is from cs 1.6 but half life has the same problem. I don't want to tell how it's done(don't want to exploit it). I think you'll figure it out and fix it. Just a small hint that's not space.

If you want to help you should provide information about this bug.

[metita]

That is not the way how it works... you need to explain how it's done otherwise just don't post it.

This can be a pretty easy fix and could be implemented in the next release easily, there is no problem if you just post it here.

You can always message Mike on his personal e-mail if you don't want to reveal it: [email protected]

Two identical names in the same server.

This was "already" posted here #2629 but lacks information, so I just decided to create a separate issue.

We managed to repro this in latest beta branch, thanks to @oaus and @FEDERICOMB, this is probably related to SV_CheckForDuplicateNames.

Output from Notepad++ (ANSI):

1. Connect to a server, change your name to Github lol.
2. Open Console and write name Github lol (WITHOUT USING NORMAL SPACE BUT ALT + 255)
3. Voila, it should replicate that name easily.

@mikela-valve This came after that fix made in sv_checkforduplicatenames http://pvpru.com/board/showthread.php?t=654980

 public static string RandomSV_CheckForDuplicateNamesBug2(int length)
        {
            const string chars = "ƒ†‡‰•˜™šœžŸ¡¢£¤¥¦§©«¬®°±²³µ¶üû";
            return new string(Enumerable.Repeat(chars, length).Select(s => s[random.Next(s.Length)]).ToArray());
        }

            string SV_CheckForDuplicateNames_method1 = "\"";
            string SV_CheckForDuplicateNames_method2 = "."+RandomSV_CheckForDuplicateNamesBug2(1)+".";

            string userinfo = "\\name\\" + NameText.Lines[0] + SV_CheckForDuplicateNames_method1 + "\\_cl_autowepswitch\\" + r3 + "\\bottomcolor\\" + r7 + "\\cl_dlmax\\" + r8 + "\\cl_lc\\" + r3 + "\\cl_lw\\" + r3 + "\\cl_updaterate\\" + r6 + "\\model\\" + model + "\\topcolor\\" + r5 + "\\_vgui_menus\\" + r2 + "\\rate\\" + r9 + "\"";
            string userinfo2 = "\\name\\" + NameText.Lines[0] + SV_CheckForDuplicateNames_method2 + "\\_cl_autowepswitch\\" + r3 + "\\bottomcolor\\" + r7 + "\\cl_dlmax\\" + r8 + "\\cl_lc\\" + r3 + "\\cl_lw\\" + r3 + "\\cl_updaterate\\" + r6 + "\\model\\" + model + "\\topcolor\\" + r5 + "\\_vgui_menus\\" + r2 + "\\rate\\" + r9;

@basuritashka You sure that's the email?

[metita]

@agrastiOs Yup, check his Github profile.

[magister4813]

This can also be done with some russian letters.

[agrastiOs]

@basuritashka Oh yeah lol, I forgot.

[mi0epro]

I just don't want this to become something big which everyone uses. But you got the point. I hope you fix it. And have a nice day xD

[metita]

@mikela-valve This issue should be fixed in the near future too because it can be easily exploited to spoof someone name, it is not that hard to reproduce (look at @kisak-valve post that got transferred from a issue I made some weeks ago)

[deprale]

You literally add a space char at the end of the name...
