Question, why did you "buy" five IP's. I would love to know what you plan to do with them. I have one IP and route my other two computers through Linux to the internet. As for tech(no)support, I would not be surprise if you were right about them passing the phone around. The sad thing is that I know as much about networking as there level one and two people do and the only training I had was a semester of networking at St. Paul Tech and the course was not that great either. Other information: I have two NICs registered with ATT Broadband (mediaone). They allow you to have up to three registered, you can only use them one at a time. Try putting a second NIC in your Linux machine and try connecting, say your laptop, through it out to the internet. I have hard coded the IP address for the intranet because that is the only way I know how to do it right now. I am using 192.168.0.1 through 192.168.0.3. I don't need to access the other two machines from outside my home so this setup works well. As per the warning I received yesterday. Here is my message in plain text, thanks to all for not flaming me. John Miller Dain Rauscher Inc.

I purchased 5 dhcp ip's and usually can only get 2 to work. The problem seems to be that after a certain perioid of time the cable modem refuses to allow more adderss requests to be forwarded. I've had success rebooting the modem and immediately doing all five of my dhcp requests. Then it will allow them. But if I need to connect my laptop from work I have to reboot the modem again or else the laptop wont work. I've done sniffer traces on linux and windows 98 and the DHCP requests are going out fine. I've even had to identical linux boxes send out the same dhcp requests (different mac's of course) and their DHCP server will respond to one but not the other until i reboot to modem. Downside to rebooting is that after the cable modem reboots i have to do a ping from each machine because if there is no network traffic after a period of time the cable modem will ignore even the previous valid ips thus causing the dhcp renewal to fail ~12 hours later and Im back to sqaure one. It's stupid and of course timewarner had no clue (even their level 3 people-- which is probably their help desk passing the phone around). They suggest things like if your using a hub then its a problem because a hub doesnt forward DHCP requests fast enough (recidulous) and they tell me they dont support hubs and point the problem at it. This of course after i reporduce the problem for them plugging directly into the modem. People at these cable companies need to pull their heads out of their asses and learn how to manage a network infrastructure.

When I try to connect with my RH 7.0 box i keep getting the error timed out waiting for a valid DHCP server response. I have researched this online and have come up with the advice that dhcpcd needs the -h option with a mysterious hostname i.e Cxxxxxx-a, which the AT&T helpless desk knows nothing about. I would really like some help on this before I go insane. Thank you in advance. D.J. Callais djx at mediaone.net P.S. My windoze box connects fine. Exact same NIC as the linux box. _______________________________________________ tclug-list mailing list tclug-list at mn-linux.org https://mailman.mn-linux.org/mailman/listinfo/tclug-list
