Network commands

	Solaris	Red Hat	Ubuntu/Debian	HP	AIX
Basic network information    (hostname, ip address)	/etc/hostname.hme0	/etc/sysconfig/network /etc/sysconfig/network-scripts/ifcfg-eth0	/etc/network/interfaces	/etc/rc.config.d/netconf	stores information in the ODM (Object Database Manager)
displaying network interfaces	prtdiag -v  ifconfig -a  kstat hme:0 kstat e1000g:0	ifconfig system-config-network (GUI)	ifconfig	ioscan -funC lan (list hardware)  lanscan -v (list configured) ifconfig lan0 (individual)	ifconfig -a entstat -d <interface> lsdev -Cc if lsdev -Cc tcpip odmget -q "name=en0" CuAt lsattr -EHl en0
Configure network interface	ifconfig	ifconfig	ifconfig	ifconfig <interface>	mktcpip (completely setup a network interface) rmtcpip (remove all network interfaces) # configure an interface mktcpip -h aix1 -a 192.168.1.200 -m 255.255.255.0 -i en1 -g 192.168.0.10 -h - hostname assigned to interface -a - ip address -m - netmask -i - interface name -g - gateway ip address # remove an interface ifconfig en1 detach  ifconfig (configures IP address) chdev (add aliases to network interface)
Starting and stopping a network interface	ifconfig qfe0 up ifconfig qfe0 down	/sbin/ifup eth0 /sbin/ifdown eth0	/sbin/ifup eth0 /sbin/ifdown eth0	ifconfig lan0 up ifconfig lan0 down note: there is no "ifconfig -a" in hpux use lanscan then "ifconfig <interface>"	ifconfig en0 up ifconfig en0 down ifconfig en0 detach (remove)
Setting NIC speed	ndd -set <device> <parm> <value> (dynamically)  /etc/system (edit and update then reboot - permanent)	mii-tool -F 100baseTx-FD eth0 ethtool -s eth1 speed 100 duplex full	ethtool -s eth1 speed 100 duplex full	ndd -set <device> <parm> <value> lanadmin -X <option> lan0	chdev -l ent0 -a media_speed=1000_Full_Duplex -P chdev -l ent0 -a media_speed=Auto_Negotiation -P  Note: entX - physical device enX - frame type run on entX
Change NIC parameters	ndd -get <device> <parm> # List parameters  ndd -get /dev/hme \? ndd -get /dev/e1000g0 \? ndd -get /dev/ip \? ndd -get /dev/tcp \?	mii-tool -v  ethtool eth1 ethtool -t eth0 online  sysctl -a | grep net*	ethtool eth0  sysctl -a |grep net*	lanadmin -> lan -> display ## options supported  ndd -get /dev/ip ? ndd -get /dev/tcp ? ndd -get /dev/arp ? ndd -get /dev/udp ?	netstat -v entstat -d <interface>  no -a no -o "ipforwarding=1"
Display NIC statistics				netstat -i [-I interface]  netstat -s	netstat -i [-f inet]  netstat -s  entstat -d <interface>
display MAC address	ifconfig -a (as user root)	ifconfig system-config-network (GUI)	ifconfig	lanscan	netstat -ia
Displaying network packets	snoop -d <interface>	tcpdump -i <interface> ethereal (needs to be installed)	tcpdump -i <interface> ethereal (needs to be installed)	nettl -start nettl -status all nettl -tn pduin pduout -e ns_ls_driver -file /var/adm/LAN nettl -stop use netfmt to display the trace file	tcpdump -i <interface>  iptrace -i <interface> <output file> ipreport (used with iptrace to view reports)  Note: you must stop the iptrace by using "kill -15"
default router	/etc/defaultrouter route add default <gteway>	edit /etc/sysconfig/network add: GATEWAY=<IP address>	edit /etc/network/interfaces add: gateway <IP address>	/etc/rc.config.d/netconf	route add 0 <gateway IP address> Note: there is no file that holds the default router
display routing table	netstat -rn	netstat -rn route -n	netstat -rn route -n	netstat -rn	netstat -rn netstat -r -f inet lsattr -EHl inet0 -a route
Test IPMP, Bonding	if_mpadm -d           (detach) if_mpadm -r           (reattach) tail /var/adm/messages	ifenslave -d bond0 eth1   (detach)  ifenslave bond0 eth1       (reattach) cat /proc/net/bonding/bond0	ifenslave -d bond0 eth1   (detach)  ifenslave bond0 eth1       (reattach) cat /proc/net/bonding/bond0	You buy an optional product called Auto-Port Aggragation.	smitty etherchannel (creates, deletes and tests)  entstat -d ent0
change the hostname	change the following files: /etc/nodename /etc/hostname.<interface> /etc/inet/hosts /etc/inet/ipnodes /etc/net - few files in here as well	/etc/sysconfig/network /etc/hosts sysctl -a |grep hostname	/etc/hostname /etc/hosts sysctl -a |grep hostname	set_parms hostname (requires reboot)	hostname <new hostname>  chdev -l inet0 -a hostname=<hostname>
setup DNS	/etc/resolv.conf	/etc/resolv.conf	/etc/resolv.conf	/etc/resolv.conf	/etc/resolv.conf

Flush DNS cache	svcadm restart system/name-service-cache:default	## if installed  service nscd restart		n/a	netcdctrl -t dns -e hosts -f
Domain Name	/etc/defaultdomain	/etc/sysconfig/network  (HOSTNAME option) /etc/resolv.conf  Note: for NIS use the NISDOMAIN option	/etc/host /etc/resolv.conf	/etc/rc.config.d/netconf	domainname <domainname>
