Hi everyone, I would realy appreciate your help and guidense with a problem I have. Im trying to set up a SMS Gateway as a alert system for my network. Although the Aircard is picked up as a usb device and has a driver in the kernel, it does not have a /dev/XXX device name. So my question is how do I create this /dev/XXX device and make it persistent. I have installed CentOS as my base with smstools-3.0.10-4.el5.i386.rpm as my application. [root at odie ~]# cat /etc/redhat-release CentOS release 5.2 (Final) [root at odie ~]# uname -rvpi 2.6.18-92.1.22.el5 #1 SMP Tue Dec 16 12:03:43 EST 2008 i686 i386 [root at odie ~]# rpm -qa | grep smstools smstools-3.0.10-4.el5 The config file for this software looks like this [root at odie ~]# cat /etc/smsd.conf # Example smsd.conf. Read the manual for a description # #devices = (eg. GSM1) #logfile = /var/log/smsd.log #loglevel = 7 # #[GSM1] #device = /dev/ttyS0 #incoming = yes #pin = 1111 # devices = (eg. CDMA1 or GSM1) logfile = /var/log/smsd.log loglevel = 5 [CDMA1] device = /dev/ttyUSB0 <==== How do I check this and what about after a reboot ... can I force it to stay the same? incoming = yes baudrate = 115200 The hardware is a Compaq nc 8000 laptop (The laptop will be located in my server room ...) I have installed a Mobile broadband data PCMCIA card ==> Sierra Wireless AirCard 580 from our local telecom provider [root at odie ~]# lspcmcia Socket 0 Bridge: [yenta_cardbus] (bus ID: 0000:02:06.0) Socket 1 Bridge: [yenta_cardbus] (bus ID: 0000:02:06.1) CardBus card -- see "lspci" for more information Socket 2 Bridge: [yenta_cardbus] (bus ID: 0000:02:06.3) [root at odie ~]# lspci 00:00.0 Host bridge: Intel Corporation 82855PM Processor to I/O Controller (rev 03) 00:01.0 PCI bridge: Intel Corporation 82855PM Processor to AGP Controller (rev 03) 00:1d.0 USB Controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller #1 (rev 03) 00:1d.1 USB Controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller #2 (rev 03) 00:1d.2 USB Controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller #3 (rev 03) 00:1d.7 USB Controller: Intel Corporation 82801DB/DBM (ICH4/ICH4-M) USB2 EHCI Controller (rev 03) 00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev 83) 00:1f.0 ISA bridge: Intel Corporation 82801DBM (ICH4-M) LPC Interface Bridge (rev 03) 00:1f.1 IDE interface: Intel Corporation 82801DBM (ICH4-M) IDE Controller (rev 03) 00:1f.5 Multimedia audio controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 03) 00:1f.6 Modem: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Modem Controller (rev 03) 01:00.0 VGA compatible controller: ATI Technologies Inc RV350 [Mobility Radeon 9600 M10] 02:06.0 CardBus bridge: O2 Micro, Inc.
