SFR Huawei 3G+ USB key with Debian

Wednesday, July 29th, 2009

After Orange GPRS with Nokia 6630 and SFR GPRS with Nokia E65, I use now mainly Huawei 3G+ USB key with SFR (french mobile phone provider).

lsusb info about this Huawei 3G+ USB key:

Bus 003 Device 003: ID 12d1:1003 Huawei Technologies Co., Ltd. E220 HSDPA Modem / E270 HSDPA/HSUPA Modem

And dmesg info:

[208765.818448] option 3-1:1.0: GSM modem (1-port) converter detected
[208765.818448] usb 3-1: GSM modem (1-port) converter now attached to ttyUSB3

[208770.887881] sr 12:0:0:0: Attached scsi generic sg1 type 5

For connecting, I tried an infamous GUI distributed by Vodafone in Debian package. Too buggy, too complex. The best solution is using a PPP chatscript.

Then, plug USB key, sleep 20 and unlock it:

echo 'at+cpin="1234"' > /dev/ttyUSB3

Note: 1234 is PIN code (or not) and /dev/ttyUSB3 is modem device.

Create these 2 files:

/etc/ppp/peers/gprs:

noauth
debug
nodetach
connect "/usr/sbin/chat -v -f /etc/ppp/peers/huawei-e220.chat"
/dev/ttyUSB3
230400
crtscts
defaultroute
noipdefault
user ignored
remotename whatever
ipparam whatever
usepeerdns

/etc/ppp/peers/huawei-e220.chat:

# Chat file for Huawei E220 HSDPA USB modem
ABORT BUSY ABORT 'NO CARRIER' ABORT 'NO ANSWER' ABORT DELAYED
'' AT
OK ATZ
OK 'ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0'
OK 'AT+CGDCONT=1,"IP","websfr"'
OK ATDT*99***1#
CONNECT ""

Finally you can:

pppd call gprs

JCE non limitées sous Debian

Thursday, July 2nd, 2009

Les packages Debian de Java n’intègrent pas de mécanisme pour faciliter l’utilisation des versions non limitées des JCE (Java Cryptography Extension), utiles pour avoir des fonctions de chiffrement dites « fortes » (#466675). L’idée est de créer des diversions locales pour conserver les versions non limitées, même en cas de mise-à-jour :

# dpkg-divert --divert /usr/share/doc/sun-java6-jre/US_export_policy.jar.ori \
 --rename /usr/lib/jvm/java-6-sun-1.6.0.12/jre/lib/security/US_export_policy.jar
Adding `local diversion of /usr/lib/jvm/java-6-sun-1.6.0.12/jre/lib/security/US_export_policy.jar
 to /usr/share/doc/sun-java6-jre/US_export_policy.jar.ori'
# dpkg-divert --divert /usr/share/doc/sun-java6-jre/local_policy.jar.ori \
--rename /usr/lib/jvm/java-6-sun-1.6.0.12/jre/lib/security/local_policy.jar 
Adding `local diversion of /usr/lib/jvm/java-6-sun-1.6.0.12/jre/lib/security/local_policy.jar
to /usr/share/doc/sun-java6-jre/local_policy.jar.ori'

Attention, bien garder à l’esprit que si une faille de sécurité survient, il faudra mettre à jour manuellement ces fichiers.
