Matching DNS Setup on Dual Boot System Not Working


Hello All
Here is my problem. I'm dual-booting Windows 7 and Slackware 14.1 from a re-built (single) PC. I have Cable One for my ISP and I get internet access from both OS's. However, when I use Slackware, I periodically get greeted with an "Unable to Identify You" message from Cable One. I have to back page and continue again error-free until about 5 minutes of browsing and the same message pops up. I contacted Cable One's technical help and we rebooted the cable modem and PC and everything was fine until the next day and the same problem came up. Cable One says that I need to flush the DNS cache when switching OS's. I thought maybe if I can config Slackware to provide the same info to the DNS server as Win7 then this will solve my problem. So I did the following.

1) I logged into my modem's configuration page and verified that the MAC ID and the hardware IP addresses does not change between OS.

2) I copied my Win7's hostname into DHCP_HOSTNAME[0] in /etc/rc.d/rc.inet1.conf I also confirmed that USE_DHCP[0]="yes"

3) When I executed the following cmd # hostname -i, I got back 127.0.01 which isn't the name I entered in rc.inet1.conf. I wonder if Slackware is sending this to the DNS server instead of the name that I provided.

After doing the above and rebooting, I'm still plagued with the error. Any advice or recommendation? My modem is Zoom 5352 and I'm using a wired connection. I would prefer to hotswap OS's without powering down both the modem and PC.

/etc/hosts

I can't help with your overall problem but my understanding is that hostname -i will return the IP address of your host, not it's name. The information comes from the /etc/hosts file I believe.

hostname by itself returns your host name
hostname --fqdn returns the long version.

Your hostname is stored in /etc/HOSTNAME and may require a reboot before a change becomes effective if I remember correctly.

See the man pages for hostname.

However I don't know if any of this has to do with your problem. I just didn't want you going down the wrong path by misinterpreting your hostname command response.

EDIT: I wonder if your ISP or modem requires some identification service that you're not running (auth). If the message is on a browser then it may be a cookie issue or a limitation that you can't get around. Hopefully others more knowledgeable will respond.

ISP the cause.

Just an update in case anyone was following this, the source to my problem was my internet source provider. I was busy trying to match my Slackware's DNS setup to my Windows 7 setup when I noticed that I was getting the same error on my iPhone whenever I was browsing the web via my wifi network. Since my iPhone was having the same problem as Slackware, I realized this wasn't an OS issue anymore. I reset my Slackware DNS setting back to its default setting and called my ISP (Cable One). I had to call 3 times in order to get someone who was knowledgable enough to look into this problem. The other two were convinced that the issue was on my side (my PC). For a while, I was seriously complating switching ISP's, however Cable One did finally fix it on their side and I have been running error-free on my Win7, Slackware and iPhone for the last 2 weeks.
