hi... i'm trying to install an app 'condor' which communicates betwen machines. i've got it on two test machines linux (rh8.0), but the app seems to be having a problem in communicating with each other... i can 'see' each box from the other box by pinging the respective boxes. however, i'm getting some form of warning that appears to point to the /etc/hosts file. can someone tell me what/how the /etc/hosts file is supposed to be.. and what the problem might be with my version, as well as how it might be corrected. for the purpose of this test, i don't have 'iptables' running.. so all the required ports for the app are wide open... thanks for any help/assistance as this is critical for me to make progress.... -bruce -------------------------------------------------------- application information... i have managed to get condor up/running on two linux boxes. however, when i attempt to do a 'condor_status' on the 'central manager' it shows only one machine. an examination of the /home/condor/log/CollectorLog file shows a warning refering to the /etc/host file. it appears that the 2nd machine is not able to 'see' the 'central manager' condor... 10/7 07:54:19 ** condor_collector (CONDOR_COLLECTOR) STARTING UP 10/7 07:54:19 ** /opt/condor-6.6.6/sbin/condor_collector 10/7 07:54:19 ** $CondorVersion: 6.6.6 Jul 26 2004 $ 10/7 07:54:19 ** $CondorPlatform: I386-LINUX_RH9 $ 10/7 07:54:19 ** PID = 1428 10/7 07:54:19 ****************************************************** 10/7 07:54:19 Using config file: /opt/condor-6.6.6/etc/condor_config 10/7 07:54:19 Using local config files: /home/condor/condor_config.local 10/7 07:54:19 DaemonCore: Command Socket at <127.0.0.1:9618> 10/7 07:54:19 WARNING: Condor is running on the loopback address (127.0.0.1) 10/7 07:54:19 of this machine, and is not visible to other hosts! 10/7 07:54:19 This may be due to a misconfigured /etc/hosts file. 10/7 07:54:19 Please make sure your hostname is not listed on the 10/7 07:54:19 same line as localhost in /etc/hosts. 10/7 07:54:19 In ViewServer::Init() 10/7 07:54:19 In CollectorDaemon::Init() 10/7 07:54:19 In ViewServer::Config() 10/7 07:54:19 In CollectorDaemon::Config() 10/7 07:54:19 enable: Creating stats hash table 10/7 07:54:19 (Sent 0 ads in response to query) 10/7 07:54:19 Got QUERY_STARTD_PVT_ADS 10/7 07:54:19 (Sent 0 ads in response to query) 10/7 07:54:20 WARNING: No master ad for < localhost.localdomain > 10/7 07:54:20 ScheddAd : Inserting ** "< localhost.localdomain , 127.0.0.1 >" 10/7 07:54:20 stats: Inserting new hashent for 'Schedd':'localhost.localdomain':'127.0.0.1' 10/7 07:54:24 ** Master < localhost.localdomain > rejuvenated from recently down 10/7 07:54:24 stats: Inserting new hashent for 'Master':'localhost.localdomain':'127.0.0.1' 10/7 07:54:32 StartdAd : Inserting ** "< localhost.localdomain , 127.0.0.1 >" 10/7 07:54:32 stats: Inserting new hashent for 'Start':'localhost.localdomain':'127.0.0.1' 10/7 07:54:32 StartdPvtAd : Inserting ** "< localhost.localdomain , 127.0.0.1 >" 10/7 07:54:32 stats: Inserting new hashent for 'StartdPvt':'localhost.localdomain':'127.0.0.1' ------------------------ the /etc/hosts file is: [root@lserver5 etc]# cat /etc/hosts # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 lserver5 localhost.localdomain localhost 192.168.1.57 lserver7 is there something that i should do to the /etc/hosts file. why am i able to ping/access the 'central manager' machine (lserver5) from the client machine (lserver2) by simply 'ping lserver5'.... i can provide the relevant portion of the 'condor_config' file if needed. i'm really at a loss as to how to proceed!!!!!!! -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
