Hi,

I have established the ppp connection between my linux machine and iridium modem. The connection lasts for a long time. But when I ping some ftp server or the modem's ip address, it's getting disconnected.


Please help me with this issue.

I am using /sbin/pppd call iridium to start the ppp connection.

and /etc/ppp/peers/iridium has the following things,

user directinternet
ttyS0 19200 crtscts
connect-delay 10000
debug
mtu 1500
mru 1500
nobscdcomp
nodeflate
noccp
noaccomp
-ac
-pc
-vj
noipx
maxfail 10
asyncmap 0
modem
defaultroute
lock
+chap
noauth
noipdefault
linkname base_station1
connect '/sbin/chat -s -v -f /etc/ppp/chat-irid3
------

/etc/ppp/chat-irid3 has the following,
ABORT "NO CARRIER"
ABORT "NO DIALTONE"
ABORT " ERROR"
ABORT "BUSY"
ABORT "RINGING"
TIMEOUT 90
REPORT CARRIER
"" "at"
'OK-+++\c-OK' "ath0"
OK "at+csqf?"
OK "at+cbst=71,0,1"
OK "at+cr=1"
OK "atd008816000025"
CONNECT

Please let me know if you want further details.

Thanks in advance.
