I want to receive SMS notifications when something is terribly wrong in our data center. One part of the problem is OpenNMS, and we know how to configure it. But another part is actually sending SMS.
As only physical server with normal USB ports which we have is self-assembled SuperMicro storage, running OpenIndiana, we want to create OI zone, which can send SMS. First of all, we'll need some USB modem. I use Huawei e1550, which was already switched to modem-only mode (AT^U2DIAG=0) on Windows PC. Let's look at prtconf -v (looking for HUAWEI):
device, instance #0

name='reg' type=int items=1
value=00000006
name='assigned-address' type=int items=1
value=00000003
If modem was switched to modem-only mode, you'll see
value='usb12d1,1001.0' + 'usb12d1,1001' + 'usb,device'in 'compatible' field.So, let's say OI that it should use usbsacm to talk to it:
# update_drv -a -i 'usb12d1,1001' usbsacm
Now you should have /dev/term/0 - 3 devices and can use tip to talk to /dev/term/0:
# tip /dev/term/0 connected AT OK ~^D
Let's create zone and pass /dev/term/0 to the zone:
# zonecfg -z sms1 sms1: No such zone configured Use 'create' to begin configuring a new zone. zonecfg:sms1> create zonecfg:sms1> set zonepath=/zones/sms1 zonecfg:sms1> set brand=ipkg zonecfg:sms1> set autoboot=true zonecfg:sms1> set ip-type=exclusive zonecfg:sms1> add net zonecfg:sms1:net> set physical=sms10 zonecfg:sms1:net> end zonecfg:sms1> add device zonecfg:sms1:device> set match=/dev/term/0 zonecfg:sms1:device> end zonecfg:sms1> exit # zfs create data0/zones/sms1 # zoneadm -z sms1 install # zoneadm -z sms1 boot
Now we can configure network in our zone:
# zlogin sms1 # ipadm create-if sms10 # ipadm create-addr -T static -alocal=192.168.1.2/24 sms10/v4 # route add -p -net 0 192.168.1.1 # cp /etc/nsswitch.dns /etc/nsswitch.conf # echo 'nameserver 8.8.8.8' > /etc/resolv.conf # svcadm enable dns/client
We'll use gammu utilities to send sms:
# pkg install utility/gammu
Your /etc/gammurc (or ~/.gammurc) should look like:
[gammu] device = /dev/term/0 connection = at
If everything is fine, now you can send SMS:
# gammu sendsms TEXT +7myphone -text "test"
