Re: Problem with gw_gethostbyname in Stable version 1.4.3

Tue, 10 Aug 2010 07:18:44 -0700 

Nikos,

Thanks for the reply and sorry about the incorrect list.
The variable is called "name" in the function gw_gethostbyname in 
gwlib/protected.c.
Line 186: int gw_gethostbyname(struct hostent *ent, const char *name, char 
**buff)

If I print this variable before it is passed to:

while ((res=gethostbyname_r(name, &hp, *buff, bufflen, &tmphp, &herr)) == 
ERANGE) {

it prints out 2.2.2.2:9001 instead of just 2.2.2.2


Here is my /etc/hosts file:

127.0.0.1       localhost
10.20.10.6      Amstel.telrite.com      Amstel
2.2.2.2        smstest.laborbridge.com

# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts



I am able to telnet to port 9001 on 2.2.2.2 but not port 9201? Was that a typo?

Thanks,
Brian

Hi,

Always use users list for such questions.

Add your server to /etc/hosts.

I don't know to which variable "name" you are referring to.

Try:

telnet 2222 9201
from a shell to see if you have connectivity to HTTP smsc. That address 2.2.2.2 in your send-url looks mighty suspicious. 

BR,
Nikos

Hi, I am attempting to connect two Kannel servers at two different locations via the smsc group using smsc = http. I have tried this on three different server and I am getting the same bevahior on all three (system 1: debian 5.0.5, system 2: Ubuntu 9.04, system 3: Ubuntu 10.04). In all three cases, when I send a message via the sendsms-user group, I get the following error:
2010-08-09 10:13:47 [9636] [17] ERROR: Error while gw_gethostbyname occurs. 
2010-08-09 10:13:47 [9636] [17] ERROR: System error 3: No such process
2010-08-09 10:13:47 [9636] [17] ERROR: gethostbyname failed
2010-08-09 10:13:47 [9636] [17] ERROR: error connecting to server `2.2.2.2:9001' at port `9001'
I googled several things before bothering you guys, and even tried adding some code to the protected.c file in the gw_gethostbyname function to try and figure out what was going on. What I found, was that the "name" variable is showing up as 2.2.2.2:9001 instead of just 2.2.2.2. I'm not sure if this correct or not. 

Anyways, here is my config and my logs:
