How zsh handles a command returning with no newline

Mar 13, 2014

73387# ^Looks something like that. The actual data are the numbers, with the ‘#’ added (with inverse coloring b/w fg and bg colors) and my shell newlined. This is an intended zsh feature, not a problem. PROMPT_SP Attempt to preserve a partial line (i.e. a line that did not end with a newline) that would otherwise be covered up by the command prompt due to the PROMPT_CR option. This works by outputting some cursor-control characters, including a series of spaces, that should make the terminal wrap to the next line when a partial line is present (note that this is only successful if your terminal has automatic margins, which is typical).

Changing your irssi config when using znc

Mar 5, 2014

So I had the normal irssi config stuff all defined and all setup from my non-bouncer days. So I figured, with the bouncer, it shouldn’t be hard to get changed over etc.. Here is what I had pre-bouncer: servers= { { address = “server.com”; chatnet = “derp”; port = “1820”; use_ssl = “yes”; ssl_verify = “no”; autoconnect = “Yes”; }, ); chatnets = { derp = { type = “IRC”; nick = “username”; };

A zsh function for saving your ass during iptables hacking

Feb 28, 2014

What this does is allow you to easily work with iptables without the fear of ever being locked out of a remote box. Trust me, when it happens, you’ll wish you had something like this. All you really would need to change to use this yourself is the FLUSH_WAIT timer and maybe some of the print’s. Otherwise, this should work across pretty much all systems. Read the comments to learn more about what this does.

Using Hping

Feb 28, 2014

hping is nice for sending a bunch of traffic just to test certain reactions of remote machines etc.. Here are some cool ways to use it and some useful links on more info. Start a flood of icmp packets with a rand src: hping 16.0.24.2 –rand-source –flood –icmp -V Do 500pps with just one src: hping 16.0.24.2 -i u2000 –icmp -V Here, we use the -i u2000 which tells hping to send a packet every 2000us which is 500 packets per second.

Want all traffic destined for 16.0.24.0/24 to go through your interface with ip 192.168.192.7? route add -net 16.0.24.0 netmask 255.255.255.0 gw 192.168.192.7 To delete this route, route del -net 16.0.24.0/24 Ohh and static arp to one of the hosts in that network? arp -s 16.0.24.2 00:50:49:A0:9E:E0 It’s so easy!

Dealing with Bash/zsh coloring and prompting users

Feb 28, 2014

http://misc.flogisoft.com/bash/tip_colors_and_formatting Also, see this archlinux wiki page. ^An extremely reliable and helpful source! Note if doing echo’s, be sure to do an echo -e “stuff” instead of just echo “stuff”. In zsh (maybe bash too), I like to do the following for prompts: (gold asking text, cyan (underlined) link, newline and white ‘>’ character waiting for user input) print -nP “\e[0;33mAre you sure you want to do this?, y|n? If not, go here:\e[0m \e[4;36mhttps://randonplace.

Use a proxy with Plex/plexweb using ncat

Feb 26, 2014

So we needed to proxy our plex server through another box. That part was easy enough with a nice little ncat socket running on the proxy: ncat -k -l 32400 –sh-exec “ncat server.com 32400” Now we can access through the proxy address proxy.com:32400/web which is great and all. However, to get our devices/plexweb to use the new address, some kung fu’ery is needed. Basically, your PMS install goes out and uses plex servers to figure out its external ip address.
