Related configuration:

/etc/hosts: 1021 characters per line and 34 entries total are hard limits

/etc/resolv.conf

/etc/nsswitch.conf

Config samples:

ifconfig {if_name} {IP_Addr} [(mask {subnet_mask})|(prefixlen {prefix_length})]: if neither subnet mask nor prefix length is specified, default subnet will be automatically assigned by class boundary in IPv4.
ifconfig {if_name} {trusted|untrusted}: untrusted interface can’t be remote managed by SSH/Telnet, but will reply ICMP request. BUT it can’t ping others actively.
ifconfig {if_name} mtusize 9000: MTU size set to 9000 (Jumbo frame)

Hostname change:

1. modify /etc/hosts
2. hostname {new_name}

options dns.domainname {domain_name}
options dns.enable {on|off}
options dns.cache.enable {on|off}

Status viewing:

ifconfig -a: display status of interfaces
ifconfig {if_name} {up|down}

ifstat -a: display counters of all interfaces
ifstat -z -a:clear all counters

netstat -aM: mapping context of each TCP connection
netstat -aB: Number of bytes of data sent and recieved over each TCP connection

route -sn (netstat -rn): display the current routes

U: Up, G: Gateway, H: the route to a host, R: Reject when an ARP expired or can’t be resolved, D: dynamic route by router redirect or RIP, M: route modified by router redirect, C: cloning, L: data-link layer information, S: static

routed [-n] status

dns {info|flush}

Troubleshooting:

netdiag

ping

pktt
pktt start {if_name} -d {path} -s {max_file_size} -b {buffer_size}: begin a packet sent/recieved sniffer. The file can be openen by Wireshark
pktt stop {all|if_name}

traceroute
traceroute -n {ip_addr}

ping6
