3G CDMA Modem

[kasus]

Hello,

I have 3G USB Modem, but not UMTS. It’s CDMA – CMOtech CCU-550 (PeopleNET Operator in Ukraine).
It don’t use APN, tel number is #777, and
the main is it requires authorization with login-password.
But zeroshell webUI don’t have fields Username and
Password and it have APN , which is wrong for my modem.

Help me please, how to install my modem to work
on zeroshell. If you want – I can give you SSH access to
test it or webUI. It works good on windows and on linux
with kppp or gnome-ppp.

This is part of my dmesg:

hub 1-0:1.0: unable to enumerate USB device on port 1

Yeah, I have done this!

It’s need additional AT command ATZ and to add user and password field to /root/kerbynet.cgi/scripts/3Gconnect!

Fulvio, I tried to create additional fields in the /root/kerbynet.cgi/template/3Gconfig, but I don’t understand how to write data to /var/register/net/interfaces/pppX .
I add USERNAME=$10 and PASSWORD=$11 to /root/kerbynet.cgi/scripts/make3G and to config3G scripts but it write to
/var/register/net/interfaces/ppp0/USERNAME and PASSWORD files some “ppp01” value.

[imported_fulvio]

USERNAME=${10} and PASSWORD=${11}

[kasus]

I tried to do like you say, but USERNAME and PASSWORD files in /var/register/net/interfaces/ppp0 are empty now 🙁

I have this /root/kerbynet.cgi/template/3Gconfig file:

#!/bin/sh

. /etc/kerbynet.conf

. $SCRIPTS/net.inc

DESCRIPTION="$2"

TTY="$3"

if [ "$NAT" == yes ] ; then

mkdir -p $PPPDIR/NAT/Masquerade

iptables -t nat -D POSTROUTING -o $NAME -j MASQUERADE 2> /dev/null

iptables -t nat -A POSTROUTING -o $NAME -j MASQUERADE

else

rm -rf $PPPDIR/NAT/Masquerade

iptables -t nat -D POSTROUTING -o $NAME -j MASQUERADE 2>/dev/null

fi

if ps -ef |grep 3Gconnect |grep -q $NAME || [ "$AUTO" == yes ] ; then

$SCRIPTS/3Gconnect_stop $NAME

$SCRIPTS/3Gconnect $NAME &

fi

And this is my make3G file is made like-this.

This is my 3Gconnect file:

#!/bin/bash

return;

}

So, where is error? 🙂

[kasus]

Sorry, I forgot to out here my 3g_tty_list script. I’ll post in at the evening, ok?

[kasus]

Fulvio, this is very important!
When I pluged in my USB modem it was detected as /udev/ttyACM0. But webUI says me that there ano no detected modems. So, I modify /root/kerbynet.cgi/scripts/3g_tty_list:

#!/bin/sh

. /etc/kerbynet.conf

. $SCRIPTS/net.inc

CONFIG="/udev"

cd $CONFIG

INTERFACES=`ls -d ttyUSB* 2>/dev/null`

if [ -z "$INTERFACES" ] ; then

INTERFACES=`ls -d ttyACM* 2>/dev/null`

fi

if [ -z "$INTERFACES" ] ; then

echo "Not detected"

exit

fi

for I in $INTERFACES ; do

echo "$I"

done

When I modify this script, modem in the Web Intreface was sucessfuly detected. You can add this upgrade to solve problems with ACM devices.
This is very bad solve of this problem, but it works for me…

[imported_fulvio]

Ok, I will add that in the next release.

Since the script is not in persistance storage, you don’t need to modify directly to the script.
So, I just store the patch in persistance storage /DB and copy the patch from
preboot script in startup/cron menu.

# patch 3Gconnect script for ppp connection with username and password
cp /DB/3Gconnect_patch_user_paswd /root/kerbynet.cgi/scripts/3Gconnect

The 3Gconnect_patch_user_paswd file like in the modified 3Gconnect previous post by kasus.

I think zeroshell want to keep username and password secret, so this information is not in web UI.
I also add directly the register variable USERNAME and PASSWORD.
/DB/_DB.001/var/register/system/net/interfaces/ppp0

Hopefully this sharing, can help you.

YAAAAAAA!!!! it works!! your last set of instructions did the trick…thank-you

Here is the process for anyone else that needs username password for 3G this
will work with US carriers Alltel as is, with Verizon I understand that you have
to use the APN field. I believe that Sprint will also work this way it would be nice if
a Sprint user would try it. I’m sure that it should work with CDMA carriers outside
the U.S.

1) place the following two files in the /DB directory:
filename: 3g_tty_list
code:
#!/bin/sh
. /etc/kerbynet.conf
. $SCRIPTS/net.inc
CONFIG=”/udev”
cd $CONFIG
INTERFACES=`ls -d ttyUSB* 2>/dev/null`
if [ -z “$INTERFACES” ] ; then
INTERFACES=`ls -d ttyACM* 2>/dev/null`
fi
if [ -z “$INTERFACES” ] ; then
echo “Not detected”
exit
fi
for I in $INTERFACES ; do
echo “$I”
done

---

filename:3Gconnect
code:
#!/bin/bash
. /etc/kerbynet.conf
export PPP=”$1″
[ -z “$PPP” ] && exit 1
UNIT=${PPP:3:1}

PID=`ps -ef |grep -w pppd |grep $PPP| awk ‘{print $2}’`
while [ -n “$PID” -a $I -lt 15 ] ; do
kill $PID
sleep 1
I=$((I+1))
PID=`ps -ef |grep -w pppd |grep $PPP| awk ‘{print $2}’`
done
if [ -n “$PID” ] ; then
kill -9 $PID
sleep 1
rm -f /var/run/$PPP.pid
fi
TTY=”`cat $REGISTER/system/net/interfaces/$PPP/TTY 2>/dev/null`”
if [ “$TTY” = NotDetected ] ; then
exit 1

if ! [ -r /udev/$TTY ] ; then
logger -t pppd “ppp$UNIT: ERROR: Modem /udev/$TTY unavailable.”
sleep 20
fi
fi
fi
sleep 10
done

2) create your connection using the web GUI so that it makes the ppp0 directory
3)using vim create the following two files under /var/register/system/net/interfaces/ppp0
filename:USERNAME
(the contents being the username usually modem phone number@carrier.net—xxxxxxxxxx@carriername.net)

filename:PASSWORD
in the case of alltel it is simply alltel

NOTE: this placed these files in persistent storage for me so no need for a cron job to
do this unless you are using the CD instead of a card or HD.

4) using the web GUI create the following preboot script(cron)
CODE:
cp /DB/3Gconnect /root/kerbynet.cgi/scripts
cp /DB/3g_tty_list /root/kerbynet.cgi/scripts

REBOOT THE SERVER AND DONE.

I hope that this is easily understandable, the scripts were by kasus and are in his
original posts.

I’ve done this job but still no luck.

When I tried to enable 3G link, I got this in log:
16:34:58 pppd 2.4.3 started by root, uid 0
16:35:01 Connect script failed
16:35:01 Exit.

Hi,

I have a cdma modem (huawei e220)

The dial string is: 777
APN and Optional AT string are empty.

The log is:

23:04:00 pppd 2.4.3 started by root, uid 0
23:04:02 Serial connection established.
23:04:02 Using interface ppp0
23:04:02 Connect: ppp0 /udev/ttyUSB0
23:04:07 local IP address 10.200.35.111
23:04:07 remote IP address 192.168.1.136
23:04:07 LCP terminated by peer
23:04:07 Connect time 0.0 minutes.
23:04:07 Sent 0 bytes, received 0 bytes.
23:04:10 Connection terminated.
23:04:11 Connect script failed
23:04:11 Modem hangup
23:04:11 Exit.

So apparently his getting connected and after the connexion terminated !
Strange, no?

What could be the solution?

Tks

Hello Guys!

My CDMA ISP: Intertelecom (Ukraine) used authentification by login/pass

Add this line in Pre Boot script from Web GUI:

echo "IT	*	IT" >> /tmp/ppp-secrets

sed -i 's/noauth/user ITnusepeerdns/' /root/kerbynet.cgi/scripts/3Gconnect

enjoy!
All worked 🙂
