Dogecoin Ubuntu Live CD Installer

I spent a little time today trying to come up with a single tar file and script to install dogecoin-qt on an Ubuntu live CD. This will let fellow shibes make offline wallets for better security!

You can get the code and instructions from my github here.

This version is created for 64-bit Ubuntu 12.04 Live CD. I likely have too many deps in the tar file as it is quite huge(~80MB), but it works! I'll work on shaving it down soon.

Here is what it looks like in action:

Nothing special, just going through each step and checking return code on the prior step. Hopefully most of those error messages are never seen by anyone.

If you find any deps that are missing, or know of ones I can remove please let me know. I'll write up information about creating the live CD, other steps, and dogecoin in general...but wanted to share this as I promised it on reddit.

To the moon!

NS2 Dedicated Server - Linux

Natural Selection 2 released both client and server version for Linux this week. Up till now you've had to use wine to host NS2 on Linux, now you can use Linux. This assumes you are already familiar with steamcmd, and have it working. Using Fedora below.

You have to use appId ~~4920 instead o~~f 4940. -- 4940 appId is now working.

#Had an issue with finding 32 bit libspeex libraries. I ended up
installing the below two rpms which resolved the dep issue. I also had
to install gtk2.  
[jpyth@jpyth ns2]$ ls *rpm

Currently hosting two NS2 servers. Can find them below:

Wireshark Fun

Quick and dirty way to configure a wireless router(Airport Express), to use your linux pc as a network gateway. I needed to sniff the network of some wireless devices, which can be quite handy.

You'll need to do a few things:
1.) Enable IP Forwarding
2.) Configure iptables to nat/forward traffic from in one interface and out another
3.) Bridge the device, and use dhcpd to handle dhcp for the devices(Much easier to track)

Enable IP Forwarding: 

echo 1 > /proc/sys/net/ipv4/ip_forward

Configure iptables(as root): 

#Interface you are sending traffic out(eth0)  
#Going out usb-ethernet  
iptables --table nat --append POSTROUTING --out-interface eth0 -j
MASQUERADE  
#Going out my wireless  
iptables --table nat --append POSTROUTING --out-interface wlp8s0 -j
MASQUERADE

#Interface you are forwarding traffic from(Airport hooked to this
interface)  
iptables --append FORWARD --in-interface enp7s0 -j ACCEPT

Configure dhcpd4 to hand out dhcpcd on enp7s0 

#Replace xxx IP with valid dns servers.  
[jmorgan@arch-dopey ~]$ cat /etc/dhcpd.conf  
option domain-name "arch-dopey.com";  
option domain-name-servers xxx.xxx.xxx, xxx.xxx.xxx;  
default-lease-time 14440;  
ddns-update-style none;  
deny bootp; shared-network airport {  
subnet 10.0.0.0 netmask 255.255.255.0 {  
option routers 10.0.0.1;  
option subnet-mask 255.255.255.0;  
pool { range 10.0.0.10 10.0.0.20; }  
}  
}  
#start dhcpd4  
[jmorgan@arch-dopey ~]$ sudo systemctl start dhcpd4

Launch wireshark, and watch traffic from the interface you are forwarding from(enp7s0 for me).

Enjoy

Spell Check

Simple, but I'm sure many people go around running Arch(and other distros) without spell check when using firefox/webmail/etc. Simple to fix, if you know.

I use hunspell, so I installed the English dictionary to go along with it.

Logitech g13 on Linux (Arch)

I've gamed on Linux for a few years, and about a year ago I picked up a Logitech G13. I've used the g13-git package from AUR without issue.

I remember information about g13 on Linux being a bit sparse/out-of-date when I first did it on my desktop, now that I'm doing it on my laptop I thought i'd share the steps/issues I encounter.

If you aren't running Arch, here is a link to the github g13 on Linux github project. The rest of this doc will assume you are running Arch Linux, but should help any Linux user.

Obtaining g13-git from AUR, building, and installing:

The configuration is detailed on the github project page here.In short to get working, you need a file with mappings from G13 to 'known' keys that you dump into a pipe(/tmp/g13-0) one way or another, the daemon will read from when started. When you start the daemon the available g13 keys and available system keys to map to are printed to stdout. An easy way to do this is a file with the binds that you simply cat into the pipe. 

#start g13 daemon without a g13 connected - notice the known G13 keys,
and available keys to map.

I use one mapping for all games, but you could have different binds per game. Here is mine:

At this point, you should have a working gamepad. If you do not map any keys by default all keys are mapped to 'a', I noticed the daemon would crash if left this way after a period of time. My assumption at the time(year+ ago) was due to having too many(or just >1) key mapped to the same. I never investigated/tested though, instead I started dumping my binds into the pipe before starting the daemon and the issue went away entirely. I haven't had an issue since(over a year). The only time the gamepad does not function is if I forget to start the daemon after a power cycle, or disconnect/reconnect the device.

Here is the current script I run after each time I restart my computer: 

[jpyth@arch-jm ~]$ cat startG13.sh  
#!/bin/bash

ps aux | grep g13 | grep -v grep &>/dev/null && echo "Already running-
Exiting"|| {  
cat /home/jpyth/g13/wowBinds > /tmp/g13-0  
nohup /usr/bin/g13 &  
rm nohup.out  
}

Pretty crude, I know. I started to add it as a systemd process, but there is currently a bug in the daemon. If you disconnect the g13 the daemon goes into a tight loop failing to find the device. This will consume process, and will have to be restarted once the device is reconnected anyway. I didn't want to write a wrapper to babysit the daemon....I have another plan for it by adding a bit more to onConnect, when I get that working i'll share;).

Starting Wireless On Boot With systemd

I didn't want to use a GUI to manage my wireless network. Majority of the time I will be at known locations, and when needing to join a new network doing it via command line is not difficult.

I have known networks configured, with dhcpcd and wpa_supplicant started during bootup by systemd. I also chose to log, and rotate, wpa_supplicant to help debug any network issues I might encounter. The following was done in Arch.

A few files must exist, the first is a .service file under /usr/lib/systemd/system/. The Type=forking is required since we are starting a daemon, the PIDFile is optional. If you include it, make sure you actually create a pid file when starting the process. 

#cat /usr/lib/systemd/system/wireless.service  
[Unit]  
Description=Wireless

[Service]  
Type=forking  
PIDFILE=/var/run/wireless.pid  
ExecStart=/usr/lib/systemd/scripts/wirelessStart  
ExecReload=/usr/lib/systemd/scripts/wirelessRestart  
ExecStop=/usr/lib/systemd/scripts/wirelessStop

[Install]  
WantedBy=multi-user.target

I chose to make individual Start, Restart and Stop scripts as seen above. You may do this differently. Here are mine: 

#Start Script  
#cat /usr/lib/systemd/scripts/wirelessStart  
#!/bin/bash  
ps aux | grep wpa_supplicant | grep -v grep &>/dev/null || {  
wpa_supplicant -f /var/log/wpa_supplicant/wpa_supplicant.log -B -i
wlp8s0 -P/var/run/wireless.pid -c /etc/wpa_supplicant.conf -d  
}

#Stop Script - I haven't had an issue with pkill failing to get the job done.  
#cat /usr/lib/systemd/scripts/wirelessStop  
#!/bin/bash  
pkill wpa_supplicant

#Restart Script  
#cat /usr/lib/systemd/scripts/wirelessRestart  
#!/bin/bash  
/usr/lib/systemd/scripts/wirelessStop  
sleep 3  
/usr/lib/systemd/scripts/wirelessStart

logrotate: 

#cat /etc/logrotate.d/wpa_supplicant  
/var/log/wpa_supplicant/*log {  
copytruncate  
compress  
notifempty  
missingok
