I'm a newby and was wondering if there is a way to refresh your ip congiguration. This is easily accomplished in MS. Also I am assuming this is my problem after being on the net for long periods of time. The system really starts to bog down after a while of being continuously connected. Is there some other way of fixing this problem? It goes back to speed when i reboot. Thanks.

are you refering to M$ winipcfg?
what distribution are you using?
do you only have one network card?
are you using a Local Area Network connection as opposed to a dial-up modem?


If the answer to all of the above is yes or LAN, you can try:

ALTERNATIVE ONE
1. as root, open a terminal and type:
/sbin/ifconfig -a (to check your current conection)
2. type
dhcpcd -k [return] (trying to end your lease)
3. type
dhcpcd -n [return]
4. repeat step 1 (to ensure that your lease was renewed).

ALTERNATIVE TWO

1.pump -i eth0 --status [return](check dhcp status on eth0)

2.pump -i eth0 --release [return](release eth0's dhcp IP)

3.pump -i eth0 [return](get dhcp ip for eth0)

ALTERNATIVE THREE

1. as root, open a terminal and type netconfig (this is a console)
2. Would you like to set up networking? (select yes)
3. For a dhcp setup, hit the space bar (this should "gray out" all the static IP protocol fields and hit tab until OK is selected and hit return.
