VNC install displaying incorrect IP address for viewer connection
Last modified: 2007-11-30 17:11:36 EST
Description of problem: During VNC installation, the IP address being displayed (51:51:51:51) for vncviewer connection is incorrect. Version-Release number of selected component (if applicable): anaconda-11.1.0.51-1.x86_64 anaconda-runtime-11.1.0.51-1.x86_64 How reproducible: persistent Steps to Reproduce: 1. Assuming VNC kickstart file is ks.cfg with the following content: vnc --password install url -- ftp://192.168.3.107/mysrc/fed/x86_64/os lang en_US.UTF-8 keyboard us # has multiple NIC devices, so using eth0 network --device eth0 --bootproto dhcp --hostname mazatlan2 2. Invoke the following during initial installation prompt: linux vnc ksdevice=eth0 ks=ftp://192.168.3.107/mysrc/ks/ks.cfg 3. The program installation will proceed, then install the VNC server and display the its incorrect IP address (51.51.51.51) Actual results: Starting VNC... The VNC server is now running. Please connect to 51.51.51.51:1 to begin the install... Starting graphical instalation... Expected results: Instead of 51.51.51.51:1 it should be displaying the actual IP address given by DHCP server. example: 192.168.3.29:1 Additional info: This could be hardware specific because the problem doesn't show up on other PCs (tried on 5 PCs with different configuration). The following PC system is affected: ECS (Elitegroup) K8M800-M2(v1.0) Semptron 2800+ socket 755 1GB RAM 300GB HDD NOTE: Learning the true IP address (192.168.3.29 in my case) through probing (ping), I was able to proceed with the installation using that IP address (192.168.3.29) instead of the erroneous IP address (51.51.51.51). So I suspect the program's module that obtain the IP address from DHCP is somewhat being corrupted in the process.
Chris, FYI before you dig into this too much this looks like a dup of one I filed a while back: 195218
Please run your installation again up to this point, then attach /tmp/anaconda.log to this bug report.
I can't get into the shell terminal even though it prompt "Press <enter> for a shell". I tried rsh, ssh, rlogin, telnet into the host machine but I get refusal. It only allow vncviewer to go through. Any other suggestion how to remote copy /tmp/anaconda.log file? I will try different hardware config. (use another video instead of the on-board one, and remove the extra LAN card) and see if I get the same error.
OK, I did more tests and came up with the following: 1. When there is only ONE LAN device attached, IP address is being displayed correctly. 2. When there are 2 LAN devices attached, the install program (anaconda?) is querying the IP address on the wrong device (eth1) instead of the desired one (eth0). 3. For some reason, the on-board LAN device is being defined first (eth0) on some PCs, while the other PCs defined it last (eth1). I am guessing that the order probably confused the install progam. Maybe the install program should re-query the IP address just before displaying it or just before running the VNC server? NOTE: The latest build broke the ability to bring up a shell prompt during installation on x86_64 and i386 platform. For this reason I can't access and copy the /tmp/anaconda.log file.
Okay, committed a patch to use the interface configured for installation instead of looping through all available devices and using whichever one gives back an IP address first. I think this should take care of your problem.
