Using "netstat -tu" to show current TCP and UDP connections might be all you need to do. You can use additional options with netstat for more information (such as showing what process/program is using the port). e.g. netstat -ntu Active Internet connections (w/o servers) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 192.168.1.2:57310 192.168.1.2:143 ESTABLISHED tcp 0 0 192.168.1.2:57311 192.168.1.2:143 ESTABLISHED tcp 0 0 ::ffff:192.168.1.2:143 ::ffff:192.168.1.2:57310 ESTABLISHED tcp 0 0 ::ffff:192.168.1.2:143 ::ffff:192.168.1.2:57311 ESTABLISHED The first two are IPv4, the latter two are IPv6. Note the much longer IP address, with colons between digits. Ignore the last colon-prefixed ones (57310, 143, etc.), they're the port numbers being used with those addresses. > and why on the other network PC everything is o.k, wget, curl yum > are o.k??? Chances are, that if other things are working, that they're not using IPv6 addresses at that time. I only mention IPv6 because your prior comments about explictly telling wget to use it, or not, and the differing results. To be able to use it, the entire network path between you and it would need to support it. I've seen the following about disabling ipv6 in a prior message on this mailing list (a different topic). Maybe you might want to try it. Add "alias net-pf-10 off" to /etc/modprobe.conf and reboot When debugging DNS issues, you probably want to try playing with the "dig" command, rather than other commands. You'll get more specific information about the name resolution. e.g. dig download.fedora.redhat.com ; <<>> DiG 9.3.1 <<>> download.fedora.redhat.com ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 54899 ;; flags: qr rd ra; QUERY: 1, ANSWER: 4, AUTHORITY: 3, ADDITIONAL: 0 ;; QUESTION SECTION: ;download.fedora.redhat.com.
