'olpc-netstatus' will not say XO-Mesh since it can determine one of simple mesh/school mesh/simple wifi/school wifi, or MPP. However, the DNS server in the output will correspond to the IP address of the XO acting as MPP i.e. with the modem. Please see if it is there and then it should connect. If dnsmasq is not installed, then mpp,py should log this message "No dnsmasq in RPM database. Is it installed?"

Re: MPP with two XOs and a pppd via GPRS
Some comments: - In my tests there was an error related to the module ip_conntrack that didn't prevent the scheme to work - Are you sure the dnsmasq is running? (because the mpp script you using assumes dnsmasq). Run: chkconfig dnsmasq on (to start at every boot) service dnsmasq start (for the current boot) This of course assumes that dnsmasq is installed (it is in 767). If not "yum install dnsmasq" - In your tests you can force the client XO to use the gateway writing "xo-mpp" in /etc/NetworkManager/mesh-start (that you probably need to create) Cheers!

MPP with two XOs and a pppd via GPRS
I have two XOs (XO#1 and XO#2) with build 767. XO#1 is connected using wvdial (pppd) over GPRS. I am using Vodafone's service in India. By itself, XO#1 gets online. I do have to add the nameserver to /etc/resolv.conf but other than that, it works. When I try to set XO#1 as a MPP using the mpp.py script from http://wiki.laptop.org/go/Modem#How_to_share_internet_among_other_XOs I get an error related to iptables the first time. On a second attempt, I get no errors and the mpp.py script seems to do its magic. olpc-netstatus reveals that XO#1 is in MPP mode. XO#2 cycles through the 3 channels and finally settles at mesh 1 (same as the MPP XO#1) but does not say "XO Mesh". XO#2 says "Simple mesh" and fails to get online via XO#1. Adding the nameserver t0 XO#2 does not help. Any pointers?
