OK. Well I disable SELinux and I firewall the server for myself with IPtables. I know its a different approach but....... One day I will get round to SELinux but right now its more a pain than a help. Also I downloaded FC4 and scratch installed it. It is now running Boinc successfully. I thought I would do that to see if there was anything I was not aware of and I had promised myself I would do it some time. Anyhow it works fine so I would turn off SELinux and reboot to see what happens.

Also check your firewall is allowing traffic on port 80 (and 443) to pass in and out. Run ethereal again and tell us what traffic is going out and we will see what can be done from there.

As for the Ethereal checksums well this may be a real nic fault but it may also be a super intelligent ethernet card. Some smart cards add the checksum for outbound traffic rather than have it done when the packet is constructed so ethereal has no chance of seeing it. It can happen this way and its documented better at the ethereal web site. But I guess you should be ready for a faulty nic yet.

If you wish to send me the trace of connection attempts then john_brown_gordon at ntlworld.com will find me. Please send them as ethereal files not txt. By all means filter out what you don't want to send. Many have done this and your data is safe with me as others will testify here if you ask.....its up to you.

Hope this helps and do come back and tell us.

Thanks.
Ian
