Q330-and-Wine-on-Centos.md

+This document  describes the steps to getting Wine and the Q330 software installed on Centos 7
+
+
+After wine is installed you need to download the latest software from Q330.com
+
+There are a few steps needed to get the usb to serial adapter to connect while running Willard.
+
+The first step is to update the Wine registry to connect /dev/ttyUSB0 to com1. To do this run:
+
+`wine regedit`
+
+two new string values need to be put in the registry under HKEY_LOCAL_MACHINE/Software/Wine/Ports
+
+Go to edit -> new -> String Value
+
+Name it COM1 and the data entry should be /dev/ttyUSB0
+
+Create another new entry with name COM5 but leave the data part blank. You should now be done with regedit and can close it.
+
+Another issue is the permissions needed for the /tty/USB0 device are incorrect. We need to add field to the dialout group using:
+
+`sudo usermod -a -G dialout field`
+
+The last step is to the udev rules
+
+as sudo create and edit /etc/udev/rules.d/50-ttyusb.rules with the following line
+
+`KERNEL=="ttyUSB[0-9]*",NAME="tts/USB%n",SYMLINK+="%k",GROUP="uucp",MODE="0666"`
+
+
+This should now allow Willard to communicate through COM1 to the usbtoserial device
+
+Note: The last few steps of changing permissions on the ttyUSB devices also ensures POCUS works correctly as well.
+
+In order for bader to work all rp_filter settings must be set to 0. Check their status by running:
+`sysctl -a | grep \\.rp_filter`
+
+you should see something like (among other information):
+```
+net.ipv4.conf.all.rp_filter = 1
+net.ipv4.conf.default.rp_filter = 1
+net.ipv4.conf.lo.rp_filter = 0
+net.ipv4.conf.p7p1.rp_filter = 1
+net.ipv4.conf.virbr0.rp_filter = 1
+net.ipv4.conf.virbr0-nic.rp_filter = 1
+net.ipv4.conf.wlp2s0.rp_filter = 1
+```
+
+In order to set them all to zero permanently we need to create a new conf file as sudo:
+```/etc/sysctl.d/90-disable-rp_filter.conf```
+
+the contents should be what we found above but all set to 0:
+```
+net.ipv4.conf.all.rp_filter = 0
+net.ipv4.conf.default.rp_filter = 0
+net.ipv4.conf.lo.rp_filter = 0
+net.ipv4.conf.p7p1.rp_filter = 0
+net.ipv4.conf.virbr0.rp_filter = 0
+net.ipv4.conf.virbr0-nic.rp_filter = 0
+net.ipv4.conf.wlp2s0.rp_filter = 0
+```
