Hello!
I'd like to ask you about such situation. When i display rules without
using "-n" i'm getting:
# iptables -L -v
Chain INPUT (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target prot opt in out source
destination
0 0 ACCEPT ipencap-- any any anywhere
anywhere
0 0 ACCEPT ipv6 -- any any anywhere
anywhere
1 88 ACCEPT icmp -- any any anywhere
anywhere
94 13850 ACCEPT udp -- any any anywhere
anywhere
801 632K ACCEPT tcp -- any any anywhere
anywhere
It's ok. When i add "-n" switch i'm getting:
Chain INPUT (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target prot opt in out source
destination
0 0 ACCEPT 4 -- * * 0.0.0.0/0
0.0.0.0/0
0 0 ACCEPT 41 -- * * 0.0.0.0/0
0.0.0.0/0
1 88 ACCEPT icmp -- * * 0.0.0.0/0
0.0.0.0/0
101 14402 ACCEPT udp -- * * 0.0.0.0/0
0.0.0.0/0
905 651K ACCEPT tcp -- * * 0.0.0.0/0
0.0.0.0/0
As we can see protocols "ipencap","ipv6" are shown as number but
icmp/tcp/udp wasn't displayed as number of protocol.
$ grep "tcp\|udp\|icmp" /etc/protocols
icmp 1 ICMP # internet control message protocol
tcp 6 TCP # transmission control protocol
udp 17 UDP # user datagram protocol
# iptables -V
iptables v1.4.12.1
My question is: why some protocols are always displayed as protocol name
even i use "-n" switch?
Thanks for help.
Marcin
