Brian Leonard "I have an !OpenSolaris host, configured with static IP address 10.0.1.175, running Apache. I have an Ubuntu 7.04 guest configured with host interface networking. From Ubuntu, I can open Firefox and open a web page served from !OpenSolaris. However, after a couple of page refreshes, the connection breaks, and Firefox returns with ""Failed to Connect"" Even stranger is that the only way I know how to get the guest connection working again is to reboot the host (!OpenSolaris). Presumably, there must be some zombie process I could restart to restore the connection, but even if so, it would only be temporary. Note, this problem does seem to be guest specific, because the connection works fine for me from WindowsXP. I haven't yet tried any other guests, but I'm open to suggestions if some are some known to be more robust than others. On the Ubuntu guest, the problem is easily repeatable. Note, this problem only occurs when !OpenSolaris is configured with a static IP address. When !OpenSolaris is configured with DHCP, everything works fine. Nothing jumped out at me in the log, but it's attached." defect closed network/hostif VirtualBox 2.0.2 invalid Linux Solaris
