<DIV> </DIV>
<DIV>Thanks for your advice. </DIV>
<DIV> </DIV>
<DIV>Yes, I have set "ad hoc" "SSID" "channel" "IP address" and its "netmask" on the LINUX machines. I believe that those are the common settings.</DIV>
<DIV> </DIV>
<DIV>I also have make sure that when I did an "ifconfig", the interface is "UP" and when I did an "iwconfig", the wireless configuration is as what I had set.</DIV>
<DIV> </DIV>
<DIV>However, even with the interface "UP" and the wireless setting correct, I still cannot PING another LINUX machine. This puzzles me.<BR></DIV>
<DIV>Any advice is greatly appreciated.</DIV>
<DIV> </DIV>
<DIV>Thanks in advance.</DIV>
<DIV> </DIV>
<DIV>Rdgs,</DIV>

<P>When asking for help on any mailing list you should provide information about what exactly you did already to try to get it to work. That helps others to give you advice. Anyway: you need to manually set essid (also bssid if your stations don't happen to automatically choose the same), channel, ip and netmask. You should be able to ping each other machine before trying to get olsr to work.</P>

<DIV>Hi Henning, Markus,</DIV>
<DIV> </DIV>
<DIV>Thank you for your replies and advice.</DIV>
<DIV> </DIV>
<DIV>Henning was right, it was the LINUX firewall that caused the OLSR to be not working. </DIV>
<DIV> </DIV>
<DIV>Now I am able to get 4 LINUX machines getting OLSR messages.</DIV>
<DIV> </DIV>
<DIV>However, I need to use a wireless access point to help the 4 LINUX machine "associated" to each other first, then the OLSR is able to see the 4 LINUX machines. </DIV>
<DIV> </DIV>
<DIV>Without using the wireless access point, the 4 LINUX machine cannot "see" each other using the "ad-hoc" mode of the wireless cards.</DIV>
<DIV> </DIV>
<DIV>Any idea what went wrong?</DIV>
