Packet Obfuscation disconnect char, able to login

[callyyprain]

Use latest Hercules. 

Packet Ob-: 2

Tried 20140205 and 20150513, Local fine but WAN access prompt failed to connect to server and

[status]: Request for connection of ##### (ip: 118.100.130.###).
[Notice]: Authentication accepted (account: #####, id: 2000009, ip: 118.100.130.###)
[status]: Connection of the account '#####' accepted.
[info]: Closed connection from '118.100.130.###'.
 
 
Packet Ob-: 1 
Tried 20140205 and 20150513, success.
 
Question: How to solve above issue when Enabled Packet obfuscation?

When you enable packet ob, you need to diff your client with the keys for that client which you can look in src/map/packets.h

Hi Samuel, is that possible, be done with NEMO? It's been years I never manual diff. lol

Currently I set it to 1 cuz 0 will also deny all login.

The client has it's keys set by default, if you change them you need to set them. You have 3 options.

1. Disable Packet Obfruscation in both, your client and your server config

2. Keep the Packet Obfruscation on both enabled

3. Use the Diff Samuel mentioned to set custom keys

From what you wrote it sounds like you had the obfruscation enabeld on your server, but diffed the client to disable them

Hi Riddley, I NEMO-ed Ragexe both 20140205 and 20150513 with recommended and some minor changes (Title, menu bar, official stuff, etc) but I did not disable PacketObs though.

I do not know which is the option to enable it, or is NEMO capable enabling it?

By default it is enabled, unless you use a diffed exe and it was being disabled by that person.

It's: Disable Packet Encryption below Disable Nagle Algorithm.

This is not a packet obfuscation issue, you will see a packet error if it was.

probably some bad network configure.

Hello Ridley, does this mean if I use the client with no broken keys based on the website(which I forgot) and enabled packet obfuscation on both client and the server without changing anything in the packets, packet obfuscation would work? Unless I want to use custom keys then I need to diff the client with it and put it as well on src(which I cannot make it to work after several times)

If using the client with default keys there is no edit needed. It is enabled on server by default, and the server knows the client is using by default (ofc you need to set your clientversion in mmo.h)

Alright, thanks! Will test this later

I got Ragexe from themon and Ossi. I think both non-diff exe? Then NEMO-ed as per previous reply. I couldn't find 'Packet Obs' option.

Hi Hemagx,

I was on Debian, set nameserver 8.8.8.8 and 8.8.4.4 in resolv.conf

Set static then

IP Add...

Netmask...

Network...

broadcast...

gateway..

Then ifdown and ifup, ifconfig check working fine. I even able to setup 1 RE 1 PRE and bind to same NIC IP. 192.168.X.X.

Please enlighten me if you could, I couldn't find any suspicious stuff. It only happens to WAN client. LAN is fine.

Network.conf is

client{ "WAN NO-IP:subnetmask", "local IP:subnetmask" }

server connect { "local IP:subnetmask"}

trusted {"local IP:subnetmask"}

UPDATE: Today my WAN friend connect with (20140205) packet obs enabled, working fine. Oh dear! What happen. Last 2days I must set it to 1 (optional).
