fedora8下拨号问题

我按照网上的办法进行拨号，最后到了拨号的时候出现了这个
/sbin/pppoe-connect
/sbin/pppoe-connect: line 285: ip: command not found
/sbin/pppoe-connect: line 357: ip: command not found
Using interface ppp3
not replacing existing default route via 192.168.1.1
local IP address 10.112.112.112
remote IP address 10.112.112.113
就一直走不下去了，不知道这是什么原因
