Thread: Weird DNS issue

  1. Weird DNS issue

    Hello

    I'm experiencing some weird behaviour with name resolution.
    Situation:
    machine A with FQDN A.DOMAIN.COM
    machine B with FQDN B.DOMAIN.COM running named

    when performing a telnet from machine A to machine B as:
    telnet B
    the connection hangs for 30 seconds before giving the initial login
    prompt.
    when performing a telnet from machine A to machine B as:
    telnet B.DOMAIN.COM
    the connection is instantaneously.

    Forward and reverse DNS is configured properly. (nslookup/host shows
    that forward and reverse DNS is working properly).

    Even stranger, when performing ssh B, the connection is also
    instanteneously...

    It seems that everything under inetd is suffering from this issue.

    Anyone an idea?
