TiTi somewhere.

I'm working in a small office with round 100 PC. We have a local network to work but need to separate internet with local one. After tried a lot of solution like ISA 2008, ccproxy... I really like to use open source solutions, after all I choose pfsense. Lets begin OS, I have an DELL desktop pc - optiplex 7040: core i5 7th gen, 4GB of RAM, 500 GB of HDD and it shipped with windows 10 - best windows OS atm with Hyper-V inside. With Hyper-V enabled, go to make gen 2 virtual machine, why gen 2? Because with pfsen stable branch 2.4.x, BSD core support uefi and I tried, it working very well with hyper-V

Today, I will show you how to use OpenWRT + SMSTools3 to make a tiny server for receive SMS from Operator then push it on to Telegram group. 1. Openwrt is open source, u can get newest image from ther website, just google it. 2. I using a raspberry pi B+, for very small power consuming and burn image to its microSD card. 3. After install image and start your openwrt in Pi, use a terminal and use following command:     opkg update     opkg install smstools Forget a very important thing, haha that u will need an 3G/4G dongle so u can push a SIM card and use it to send SMSs. My choice is a Huawei modem: e173eu-1, it locked with Operator Viettel in Vietnam. U will need to intall some packages then can use this dongle. They are:     kmod-usb2 kmod-usb-ohci kmod-usb-serial kmod-usb-serial-option usbutils usb-modeswitch kmod-usb-storage kmod-scsi-core kmod-scsi-cdrom kmod-scsi-generic picocom After install those packages, u can now log in...
