    Strange networking issue


    Hi - I have an internal network with a Windows 7 machine connected, as well as a CentOS 5.7 machine. The router is an old Buffalo router. I have web servers (apache) running on both.

    The CentOS server does not have iptables on, and selinux is permissive.

    With my Win7 server, I cannot ping, ssh, or access web pages served by the CentOS server, unless I do the following:

    1. With the CentOS server, I access a web page served by the Win7 server.

    2. Then, on the Win7 server, I can ping, ssh, and access web pages served by the CentOS server. But only for a couple minutes. After a couple of minutes, any further attempts to ping or ssh time out.

    3. If I then go back to the CentOS server and access a web pages on the Win7 server, I then regain server access from Win7 to CentOS as described in #2, for a minute or two.

    Any idea why this might be happening? Or what I could look at which would help solve the mystery?

    I switched the CentOS from Wireless to Wired networking and that did not make a difference.

    Really appreciate any help. Thanks.

    I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.

    Have you tried disabling SELinux entirely on the Linux system?
    Sometimes, real fast is almost as good as real time.
    Just remember, Semper Gumbi - always be flexible!
