[Chilli] CoovaChilli Kernel Mode issue

I just realized that I replied in HTML. Some mailing lists don't like HTML emails and I am reposting this. Thanks.

Hi Xabier,

I am following these instructions from David on how to enable the kernel module. http://lists.coova.org/pipermail/chilli/2010-April/001239.html

According to him, "Chilli is then also configured with 'uamlisten' of 11.0.0.1 and
this is the IP address that gets assigned to tun0 (so note that
dhcplisten and uamlisten are different!). The high level concept is that
subscribers get a 10.1.0.0/24 IP address which is routed (when
authenticated) through the kernel."

So, I guess my setup is ok. When I installed CoovaChilli in normal mode and made UAMLISTEN part of HS_NETWORK, it was ok. This issue happens only if I enable the kernel module mode.

Btw, when I looked at the syslogs, I saw the following lines when the clients got the resetting issue.

redir.c: 2020: 104 (Connection reset by peer) redir_read(0) failed!

Doing tcpdump on a client (10.99.0.30) when the issue occurred gave me the followings.
========================
16:54:09.921330 IP (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto TCP (6), length 40)
192.168.99.1.3990 > 10.99.0.30.57235: Flags [R], cksum 0xcb11 (correct), seq 2598775956, win 0, length 0
16:54:09.922202 IP (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto TCP (6), length 40)
10.99.0.30.57235 > 192.168.99.1.3990: Flags [R], cksum 0xb372 (correct), seq 524533718, win 0, length 0
16:54:09.922646 IP (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto TCP (6), length 40)
10.99.0.30.57235 > 192.168.99.1.3990: Flags [R], cksum 0xb372 (correct), seq 524533718, win 0, length 0
===============
I think it probably indicates that the server (192.168.99.1:3990) is resetting the connections even before showing the redirection page. I tested by creating a test page and put it in /www. A client won't even see the contents of that test page.
HS_UAMHOMEPAGE=http://\$HS_UAMLISTEN:\$HS_UAMPORT/www/testpage.html

I searched the forum and web for solving redir_read issue but didn't get any clue.

Thank you.

Hello Phyo, 

Are you sure you posted the configuration that you used? 

> HS_NETWORK=10.99.0.0 # HotSpot Network (must include HS_UAMLISTEN) 
> HS_NETMASK=255.255.255.0 # HotSpot Network Netmask 
> HS_UAMLISTEN=192.168.99.1 # HotSpot IP Address (on subscriber network 

As the comments say, 'HS_UAMLISTEN' must be in 'HS_NEWORK' and your isn't... 

Cheers,
