Cannot Connect to Server Via Alternate IP Address

When trying to login to an OES11 server using an alternate IP address for the server, we get the "Tree or Server not found" error. However, if I specify the IP address associated as the server's default IP address, we can log in with no problems. Does the Novell Client (for Windows 7) need to be able to resolve the IP address via DNS (the alternate IP address is not in DNS yet) or is that irrelevant?
I am trying to set a default IP address for the clients connection and have the ability to move it to another server in the event I want the users to authenticate to another server.

thanks.

  • Hey, when using an ip address, dns is not required. A few questions and suggestions. Is the alternate ip address on the same LAN or VLAN? Can you ping the alternate ip address? If the ip addresses are on the same LAN, then it is not a gateway issue. If you can ping both ip addresses, then there maybe a firewall issue. Are both ip addresses set to the same LAN card or to seperate interfaces. Try running a traceroute to each ip address. Post back some answers and I am sure we can help.

    Almost certainly for a legitimate reason... such as a firewall somewhere
    or misconfigured network, or maybe application, setting.

    Irrelevant. eDir thankfully doesn't care, almost at all, about DNS. DNS
    is not really ever used for a connection anyway... it's just a lookup to
    find an IP address so in the end the network layer protocol (IP) is, of
    course, used for the network connection.

    Using clustering on the server?

    Good luck.
  • Hi

    Double check to see if NCP is listening on the secondary IP - I found that to be the problem in my environment!

  • Hi,

    Further to what I said above....You can add IP addresses in the eDirectory configuration by editing the file /etc/opt/novell/eDirectory/conf/nds.conf

    Cheers,
  • thanks for the responses - that was going to be my next question! (Yes I can ping the second IP address) I'll give it a shot tomorrow and hopefully it will work.

  • Just FYI that being able to ping an IP address doesn't generally mean much except that the workstation has a path to that IP device and that the ICMP (echo) port wasn't blocked - doesn't really tell you what services are listening on that address 8-(

    Yes, that should be it. When having added an IP to the OES after initial OES configuration, that needs to be adjusted in the nds.conf as "it" has been configured to listen on the ip's that were available during install... at least, from what I've been seeing. After editing, it should be enough to restart ndsd... but I tend to do a planned reboot as slp registrations kick in more instantly (instead of the hour it can sometimes take).

  • I added the server alternate IP address to the nds.conf file, restarted ndsd and can authenticate using the alternate IP Address. Thanks for all the insight and help!

  • Awesome stuff :) Thanks for letting us know.
