Can anybody explain what's going on? My (otherwise normal-behaving) workstation spits out the following: $ uname -a Linux myhostname 2.6.18.5-gg10-mixed64-32 #1 SMP Tue May 8 22:29:42 PDT 2007 x86_64 GNU/Linux $ sudo iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination getsockopt failed strangely: Invalid argument ACCEPT tcp -- anywhere anywhere Please let me know what other information, if any, would be useful. Thanks in advance, Yang
