[Condor-users] ERROR "gethostbyname(xxx) failed, errno = 25" at line 173 in file my_hostname.C

Hi,

I am trying to use Condor 6.6.10 on SLES10. I wanted to set up a  
personal condor on a machine with two NICs. I have followed the  
section 3.10.7 in the manual which requires to set up the CONDOR_HOST  
and NETWORK_INTERFACE variables according to the network setup of the  
machine. But even after setting up these variables starting up  
condor_master would result the same message I have got before. Here is  
what I have tried so far. First starting with the network setup:

xxx = is the full hostname condor_master complains about, and the  
hostname of the IP where I was planning to bind condor
x = is its shortened form
AAA.AAA.AAA.AAA = is the ip address of the NIC the public network is  
available, and where I was planning to bind condor
yyy = is the full hostname of the other interface's ip
y = is its shortened form
192.168.2.81 = is the ip address of the NIC with the private network

Here is what I did to figure out the correctness of the network setup:

First I tried to configure condor on the public NIC:

condor@x:~/condor> grep NETWORK_INTERFACE etc/condor_config
NETWORK_INTERFACE = AAA.AAA.AAA.AAA
condor@x:~/condor> grep CONDOR_HOST etc/condor_config
CONDOR_HOST	= xxx
HOSTALLOW_ADMINISTRATOR = $(CONDOR_HOST)
##  COLLECTOR_HOST = $(CONDOR_HOST):1234
COLLECTOR_HOST  = $(CONDOR_HOST)
NEGOTIATOR_HOST = $(CONDOR_HOST)
condor@x:~/condor> grep LOCAL_CONFIG_FILE etc/condor_config
#LOCAL_CONFIG_FILE	= $(LOCAL_DIR)/condor_config.local
LOCAL_CONFIG_FILE = /opt/users/condor/condor/local.x/condor_config.local
#REQUIRE_LOCAL_CONFIG_FILE = TRUE
##  the global config file (not the LOCAL_CONFIG_FILE from above).
condor@x:~/condor> grep CONDOR_HOST local.x/condor_config.local
CONDOR_HOST = xxx
condor@x:~/condor> grep NETWORK_INTERFACE local.x/condor_config.local
NETWORK_INTERFACE = AAA.AAA.AAA.AAA
condor@x:~/condor> sbin/condor_master
ERROR "gethostbyname(xxx) failed, errno = 25" at line 173 in file  
my_hostname.C

Since I have received this error message, I tried to configure condor  
on the private NIC:

condor@x:~/condor> grep NETWORK_INTERFACE etc/condor_config
NETWORK_INTERFACE = 192.168.2.81
condor@x:~/condor> grep CONDOR_HOST etc/condor_config
CONDOR_HOST	= yyy
HOSTALLOW_ADMINISTRATOR = $(CONDOR_HOST)
##  COLLECTOR_HOST = $(CONDOR_HOST):1234
COLLECTOR_HOST  = $(CONDOR_HOST)
NEGOTIATOR_HOST = $(CONDOR_HOST)
condor@x:~/condor> grep LOCAL_CONFIG_FILE etc/condor_config
#LOCAL_CONFIG_FILE	= $(LOCAL_DIR)/condor_config.local
LOCAL_CONFIG_FILE = /opt/users/condor/condor/local.x/condor_config.local
#REQUIRE_LOCAL_CONFIG_FILE = TRUE
##  the global config file (not the LOCAL_CONFIG_FILE from above).
condor@x:~/condor> grep CONDOR_HOST local.x/condor_config.local
CONDOR_HOST = yyy
condor@x:~/condor> grep NETWORK_INTERFACE local.x/condor_config.local
NETWORK_INTERFACE = 192.168.2.81
condor@x:~/condor> sbin/condor_master
ERROR "gethostbyname(xxx) failed, errno = 25" at line 173 in file  
my_hostname.C


Still no luck, and I have no idea what is still missing. The last line  
is even more interesting since it is still complaining about the xxx  
hostname even though there is no reference to that hostname anymore:
condor@x:~/condor> grep -ri xxx *
condor@x:~/condor>

Can you give me a hint what to do next?
