Good choices.
I suggest iptraf, tcpdump, and iptstate are also good.
As a general rule, I find the more "graphics" the slower and harder to use,
and the less information presented.
nmc:~$ apt-cache show iptraf
Description: Interactive Colorful IP LAN Monitor
IPTraf is an ncurses-based IP LAN monitor that generates
various network statistics including TCP info, UDP counts
ICMP and OSPF information, Ethernet load info, node stats
IP checksum errors, and others.
.
Note that since 2.0.0 IPTraf requires a kernel >= 2.2
$ apt-cache show tcpdump
Description: A powerful tool for network monitoring and data acquisition
This program allows you to dump the traffic on a network. tcpdump
is able to examine IPv4, ICMPv4, IPv6, ICMPv6, UDP, TCP, SNMP, AFS
BGP, RIP, PIM, DVMRP, IGMP, SMB, OSPF, NFS and many other packet
types.
.
It can be used to print out the headers of packets on a network
interface, filter packets that match a certain expression. You can
use this tool to track down network problems, to detect "ping attacks"
or to monitor network activities. More information is at
<URL: http://www.tcpdump.org/>
$ apt-cache show iptstate
Description: Top-like state for netfilter/iptables
IP Tables State (iptstate) was originally written to implement the
"state top" feature of IP Filter for netfilter/iptables. "State top"
displays the states held by your stateful firewall in a top-like
manner.
