PPP chat-script

hAh0L13 · Dec 8, 2016, 2:51 AM

Hello.

I'm trying to use USB 4G modem Huawei e3372h in HiLink as simple 4G modem on my pfsense 2.3.2. Succesfully create PPP interface on cuau0.0, but can't connect. System Logs > PPP shows error:

ppp: [wan_link0] CHAT: ATDT*99#
ppp: [wan_link0] CHAT: Invalid dial init string.

I know about replace ATDT to ATD in /etc/inc/interfaces.inc, but my question is where I can change whole chat-script permanently? From support of Huawei e3372h, I should use this script:

ABORT BUSY
ABORT 'NO CARRIER'
ABORT ERROR
REPORT CONNECT
TIMEOUT 10
"" "ATE1"
OK 'AT+CGDCONT=1,"IP","home.beeline.ru"'
SAY "Calling UMTS/GPRS"
TIMEOUT 30
OK "ATD*99#"
CONNECT ' '

OpenWRT use /etc/chatscripts/3g.chat for this, but i can't find this file, /etc/ppp/ppp.conf didn't change script too.

Sorry for my bad-bad english and if question already answered, but i can't find anything.

@AndrewZ:

I already know about correct init strings like ATZ or AT&F (without M1), but my question isn't about it. I'm try to locate where i can change chat script, which config files system using.

I can connect with my modem - dialing ok, receive ip address. but i haven't internet. I think it's because default route is absent - maybe command 'add default HISADDR' didn't apply in dialing.

You don't need to touch any script.
Think of gateways and NAT.

@hAh0L13:

I'm trying to use USB 4G modem Huawei e3372h in HiLink
Succesfully create PPP interface

BTW, if you are able to create a PPP interface, your modem may not be in HiLink mode. I suspect it's a regular stick running 21.X firmware.

@AndrewZ:

OK, i understand this. I have another modem, 3G SimTech Sim 5216. With it, i can create PPP and receive IP address too, but can't ping 8.8.8.8 - no route to host. Similarly to e3372.

NAT in auto outbound mode. BTW, pinging from PPP interface say no route to host too. I can add default route manually (and i think all will work fine), but maybe this should be done automatically?

@AndrewZ:

BTW, if you are able to create a PPP interface, your modem may not be in HiLink mode. I suspect it's a regular stick running 21.X firmware.

HiLink with modded firmware, able to change composition between RNDIS/CDC/Gateway/Gateway(with NIC). In gateway it has 3 u3g ports - modem interface, PC UI interface and another one command interface. Now I use it in CDC composition, but internet works unsatisfactory - opening sites often say "timed out", Steam say "no connection", etc. However, when connection achieved, it may be up to 50-60 Mbps down and 10-11 Mbps up. In gateway mode huawei works fine with Win7 (standard win utility), Fedora 23 and CentOS 7 (ModemManager, part of NetworkManager) - no delay, no timed out.

UPD Found this bug - https://redmine.pfsense.org/issues/6495 and linked thread - https://forum.pfsense.org/index.php?topic=113750.30
will try this evening

I don't know how, but now all works fine. All what has been changed - removed swap for increasing / - my / is overfilled (free 1% or 9 MB). Now used 73% and PPP connection up and works fine
