Something strange is going on. I'm on Spectrum cable. The advertised bandwidth is 200Mbps. Since most of may LAN is 100Mbps Ethernet, I don't see that speed. If I plug my laptop (Gigabit Ethernet) directly into the cable modem I see the adverised bandwidth, but several things fail: fetch from Google Apps e-mail (Ruby script), outgoing mail to same account (Thunderbird), and updating Ruby gems (gem and bundle). All error messages indicate a timeout after a half minute to minute. There may be others but these I know. Web sites work fine. Outgoing e-mail thru noise.org (local Mail Service Provider) works fine. Plug into the WiFi router w/ NAT connected to the cable modem and everything works fine. This is on 42.3. I'm using OpenSuSE's firewall and Portsentry (3rd party). The logs seem to show a possible correlation with the failed services timing and TCP SYN/Normal scan from various ripe.net addresses (Portsentry). Also blocked TCP connections (SuSEfirewall2). Turning off Portsentry does not fix the problem. Stopping the firewall doesn't help either. So possibly this is a server policy to check WHOIS on connections? And with my laptop, the firewall is blocking ripe.net, the usual WHOIS provider? Suggestion, explanations, etc. welcome, Jeffrey -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

200Mbps should show about 24MBbs on most test tools. (accounting for the 8-b per B and 1024 * 1024 B per M) -- David C. Rankin, J.D.,P.E. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
