hello,
I've a FC3 with an external Elsa Microlink 56k modem on /dev/ttyS0.
all works OK (both with kppp and with the activation of the pp0 from the
network panel): I.E. the /sbin/route -n once connected says:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
212.63.96.77 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0
192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0
0.0.0.0 212.63.96.77 0.0.0.0 UG 0 0 0 ppp0
the problem is about (I guess...) DNS.
ping doesn't go, I.E.:
[root at fedora3 etc]# ping www.google.com
ping: unknown host www.google.com
[root at fedora3 etc]# ping 66.249.93.104
PING 66.249.93.104 (66.249.93.104) 56(84) bytes of data.
ping: sendmsg: Operation not permitted
...and the corresponding logs are tons of things like these:

my /etc/resolv.conf is:
search home.net
nameserver 192.168.0.50
nameserver 212.63.96.34
nameserver 212.63.96.35
192.168.0.50 DNS is ***only internal**** (home.net, for experimental
purpose) with BIND
in other words, in /var/named/chroot/etc/named.conf the outside zone is all
/*commented*/
The 212.63**** DNSs are my provider's regular and in-great-shape DNSs.
any clue?
as always thanks a lot in advance for your reply,
fabiano
