pppd connection timeout in Mesh network

pppd connection timeout in Mesh network

[littleHeart]

Hi all,

I have a problem with PPP connection timeout in my 3 nodes mesh networking
system.  Node 1 is wirelessly bridged to ADSL line and wireless mesh
networked to Node 2 and Node 3. Node 1 always stays up connected and ppp,
internet works fine. But node 2 and node 3 has problem with  ppp connection
timeout. Sometimes node 2 or node 3 has ppp vpn connection but lasts for few
minutes and then gets disconnected. Following is the log message when trying
to connect after disconnection.

Jan  1 00:02:09 OpenWrt user.info : LCP: timeout sending Config-Requests

Automatic reconnection failed with timeout for most of the time. When pppd
command is launched manually it connects (using interface ppp1) well and
stay connected. 

Can anybody precise me what exactly wrong with the ppp connection goes
disconnected and got connected when launched manually. ? 

thanks

Hi Gilles,

I am running pppd version 2.4.4 and Openwrt's Linux-2.6.26.2 on the
wireless mesh boards. pppd options contains the following info

asyncmap 0
auth
crtscts
lock
hide-password
modem
proxyarp
lcp-echo-interval 30
lcp-echo-failure 4
noipx

I have no idea about ppp configuration on the long distance server
side but sure its working fine and givingout services to other mesh
clients.

The same wireless mesh boards works well on other mesh sites. I am
experiencing problem only with this site. The ADSL line seems to work
fine cos Node 1 stays connected since the day installed. Only node 2
and node 3 goes through (bridged with) Node 1 failed most of the time.
ssh between node 1, node 2 and node 3  works perfectly and so wireless
connection do.

log shows no reception of rcvd packets and LCP timeouts.
