Networking probs w/ FC4
Hi!
I've installed FC4 these days to get rid of SuSE and ran into some networking troubles that seem tobe related to IPv6: - I can access the internet w/ firefox (IPv6 disabled in about:config) - I can ping hostnames, so DNS seems to work - I can NOT access any repositories w/ yum nor update my system w/ up2date - I can NOT access my external smtp- or pop-server w/ evolution I have installed FC4 on different machines w/ the same result - and tried multiple firewall-settings. I am connecting to the internet via a DSL-router. IP is provided by a DHCP, gateway- and DNS-settings are fine. I have no problems connecting to any internet-service w/ SuSE 9.3 (IPv6 globaly disabled) or Windows. So it seems to be an IPv6-related problem. IPv6 is not activeted in the network-setting... Any hints? I've googled for 2 days and found nothing that helped. Thanx! |
1) If you stopped the ip6tables service, try restarting it and see if the networking problems go away.
2) There was an often used ipv6 “fix” in FC2/3 involving adding the following lines to /etc/modprobe.conf and rebooting: /etc/modprobe.conf: ... alias ipv6 off alias net-pf-10 off ... |

I've added that to /etc/modprobe.conf, but it didn't change anything... Here my modprobe.conf: --- alias eth0 8139too alias ipv6 off alias net-pf-10 off alias snd-card-0 snd-intel8x0 options snd-card-0 index=0 options snd-intel8x0 index=0 remove snd-intel8x0 { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-intel8x0 alias usb-controller ehci-hcd alias usb-controller1 ohci-hcd alias usb-controller2 uhci-hcd --- When I ping any website I get fine results, e.g. --- PING www.google.de (66.249.85.104) 56(84) bytes of data. 64 bytes from www.google.de (66.249.85.104): icmp_seq=0 ttl=247 time=56.2 ms 64 bytes from www.google.de (66.249.85.104): icmp_seq=1 ttl=247 time=56.2 ms 64 bytes from www.google.de (66.249.85.104): icmp_seq=2 ttl=247 time=56.4 ms 64 bytes from www.google.de (66.249.85.104): icmp_seq=3 ttl=247 time=56.8 ms --- www.google.de ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3003ms rtt min/avg/max/mdev = 56.231/56.450/56.886/0.351 ms, pipe 2 But when I try to ping fedora.redhat.com, no packets are received: --- PING fedora.redhat.com (209.132.177.50) 56(84) bytes of data. --- fedora.redhat.com ping statistics --- 4 packets transmitted, 0 received, 100% packet loss, time 2999ms --- When I do yum list as root, I get different errors. Sometimes it's that yum can't find a valid base-url, sometimes it's that the protocol is not supported by the mirror... :confused: I have not changed any files in /etc/yum.repos.d so far. |
hi there,
first all you must check if your yum config file and your update config file. after that try pinging your smtp server. also try installng your ipv6 package forcefully . this may make something work. |

My config files are still the FC4-standard, I didn't edit them yet. I can also ping my smtp and pop server by name. I am very new to Fedora - how may I force installing the ipv6-packages? By the way: I had the chance to try FC4 on a machine on a different network (other router, other firewall but the same ISP). There it worked without any problems. So it seems that the router and/or firewall in the office network are causing the trouble... |
