Yes...it is the updated router: but it worked for a long time with FC5 and I didn't have any problem at all with yum, wget....I can't understand what changed > > I would be most interested in the contents of /etc/resolv.conf on all > machines.

Anyway this is the resolv.conf of this machine, i.e. the router with no problems.... nameserver 62.211.69.150 nameserver 212.48.4.15 and modprobe.conf alias eth0 ne2k-pci alias eth1 sk98lin alias eth2 hisax alias snd-card-0 snd-intel8x0 options snd-card-0 index=0 install snd-intel8x0 /sbin/modprobe --ignore-install snd-intel8x0 && /usr/sbin/alsactl restore >/dev/null 2>&1 || : remove snd-intel8x0 { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-intel8x0 alias usb-controller ehci-hcd alias usb-controller1 uhci-hcd > When I troubleshot an IPv6 name resolution problem at home here I used > "tcpdump -w captureFileName &" along with Ethereal to analyze the tcpdump > capture files.
