Help Interlude Vanganth and Dynamic IP

maxicroma · November 15, 2018

Basically i need to setup a L2OFF server with a dynamic ip(this ip changes every time that the modem restarts)

I have a no-ip service,and vangath files ,so i use a noip of 15 letters (it can't containt more than 15 lettters on the dbo.server table)

Example serv67.ddns.net

So When Hauth Loads the server it says External IP "127.0.0.1" ,why not serv67.ddns.net?

No problem i tried to log in the server but it get stucked on the server seleccion screen.

Both ports are open

Probably there is some way but this is much easier:

#!/usr/bin/env python

sqlcmd = "C:\\Program Files (x86)\\Microsoft SQL Server\\Client SDK\\ODBC\\130\\Tools\\Binn\\SQLCMD.EXE" # put correct path here!
server = "(local)\SQLExpress" # put correct server string here!
database = "lin2db" # database name
hauthd = "C:\\l2\\auth\\hauthd.exe" # put correct path here!

class HauthdThread(Thread):
	def __init__(self):

	def stop(self):

		if self.hauthdProcess != None: self.hauthdProcess.kill()

	def restart(self):
		self.hauthdProcess.kill()

currentIp = None
ipUpdated = False
hauthdThread = None

try:
	while True:
		try:
			newIp = loads(urlopen("https://api.ipify.org?format=json").read())["ip"]
			if newIp != currentIp:
				inet_aton(newIp) # check IP
				print >> stderr, "New IP address:", newIp
				currentIp = newIp
				isUpdated = False
		except KeyboardInterrupt, e:
			raise
		except:
			print >> stderr, "Couldn't get current IP address, will retry later"
			sleep(period)
			continue

		if isUpdated:
			sleep(period)
			continue

		try:
			popen = Popen([sqlcmd, "-S", server, "-d", database, "-Q", "UPDATE dbo.server SET ip='%s' WHERE id=%s" % (currentIp, serverId, )], shell = True)
			popen.wait()

				hauthdThread.start()

Only all offline = 127.0.0.1

maxicroma · November 15, 2018

i tried in both ip to put 127.0.0.1 ,but its the same it stucks on the server selection

Maybe a program could update the table each time it needs. I do not see other fix.

Smith · November 20, 2018

LOL ... in the table place the actual ip of your dedicated.
And point the NO-IP to your dedicated, simple ip.

You do not need to put the ip of your DDNS or NO-IP in the settings, settling to point to pro IP enough.

So simple and they break the head with it!

EDIT: You'll also need to restart hauthd somehow...

Pase por el mismo problema con advext64 y te comento como funciona. Tu licencia se asocia a una direccion IP o dominio, ahi es cuando te registras en NO-IP, te dan un dominio gratuito y dentro de la pagina de NO-ip le asignas tu IP de ISP. (cualesmiip)... Esta misma ip la pones en el campo IP en dbo.server. Ej

NO-IP:

hostname: l2xx.ddns.net

IP / TARGET: le pones el ip de tu isp (cualesmiip).

En la base de datos, en IP pones tu ip de ISP tambien.

Download and install Python 2.7 https://www.python.org/downloads/release/python-2715/ - use Windows x86-64 MSI installer.

Then just run the script as if it was normal application.
