Goal: Generate a simple text file with a list of files in it
find "/path/to/search" -type f | sort > list.txt
The -type f only returns files.
find /home/mruckman -maxdepth 1 -type d
The -type d only returns directories
mComix or feh Manga Command Line Viewer
Comix is a manga type viewer that works a bit like irfanview. Originally, I started using feh, which works from the command line but Comix seemed to meet my needs.
For Ubuntu 20.04 - MComix is a clone of Comix
Ubuntu has a command line image viewer called feh. Use apt-get to install it.
It has some basic commands, use the arrow keys to cycle through pictures, the v key to toggle to full screen.
[Shift]+[<] or [>] to rotate a picture
[Esc] or [Q] to quite
nslookup to resolve ip to name
Use the following to convert an ip address to a domain name:
nslookup ipaddress
Rotating Text in SharePoint with JavaScript
Find duplicates in text file
Use the Unix command, to print duplicate lines
uniq -d filename.txt
sort your input file and you can use the following command to count the duplicates
uniq -c sortedfile.txt
List does not exist error message
I ran into an issue today where users could not access as SharePoint 2007 Publishing Site Page. The error message was:List does not exist.
The page you selected contains a list that does not exist. It may have been deleted by another user. Troubleshoot issues with Windows SharePoint Services. I had no problem viewing my site and couldn't figure out what was wrong. I then looked at the URL for the page which was:
http://[sharepoint-site-URL]/_layouts/AccessDenied.aspx?Source=[SharePoint-site-URL]&Type=list&name=%7B2007BFAB%2D9CC4%2D41DA%2D8ED0%2D7E4C5BDAE90C%7D
The key here was the AccessDenied pages and the name query string value:
7B2007BFAB%2D9CC4%2D41DA%2D8ED0%2D7E4C5BDAE90C%7D
After decoding the html encoded characters out I got a GUID of:
{2007BFAB-9CC4-41DA-8ED0-7E4C5BDAE90C}
If you look at the name, it is actually the id of "list item" that the user has been denied access from viewing. I then went to central administration to get the name of the content database of the site I was working on, and then went to SQL Server Management Studio and expanded my content database to dbo.AllLists. I ran a query against my content database for the list that users have been denied access to.
select * from dbo.alllists
where tp_id='{2007BFAB-9CC4-41DA-8ED0-7E4C5BDAE90C}'
I received one result with a tp_Title of "Master Page Gallery." That was all I needed. I then went to my page and looked at the template it was using. It was using a custom page layout I created. I proceeded to look at my Master Page Gallery and saw that the page layout it was using was never checked in and was in a ‘pending’ status.
Not the best error message, but the lesson here is that users cannot access pages using page layouts that have never been checked it. Makes sense, but a more meaninful error message would have been nice.
Using sed for text search across multiple lines
Simple command is:
sed -n '/begin/,/end/p' input.txt
Note: the search string "begin" and the search string "end" must be on separate lines.
Firefox keeps asking for proxy credentials
Attempted to change with about:config
Set network.negotiate-auth.allow-proxies to false
Did not quite work, filtered on "proxies" and set everything back to default values.
Also, set all of the "No Proxy" settings for the browser.
Currently this appears to be a networking issue with Firefox. Currently none of my attempts to fix the problem have worked.
Use wget with -c parameter to download larger files
Using the -c parameter allows you to resume:

Setup an SSH SOCKS proxy!
Refer: http://www.mattlestock.com/
Software goodie: plink.exe
For episode 416 of HAK5, I showed how easy it really is to tunnel all kinds of traffic from HTTP, FTP, and more over a secure SSH Socks proxy.
What you’ll need is:
- An SSH server to act as your proxy.
Simple enough really! If you’re using windows I highly recommend freeSSHd. If you’re on a mac check out this page for instructions on how to enable remote logon. Linux users, you should know how to do this. - An SSH client on the computer you’re using.
Mac and *nix machines have SSH built right in at the command line. Windows users can do like I did in the episode and download plink (available here). There are other people out there that will recommend Cygwin, but for this purpose, it’s really overkill.
How proxies work
In a nutshell, what you’re doing with a proxy is setting up a middle-person (no not a pineapple, but close) between you and the internet. Using the proxy, your browser hands off web page requests to the proxy server, which handles the request and fetches the page for you from the internet. The web site actually thinks the request is coming from the proxy server, not your computer, which is a good way to obscure your originating IP address.
Additionally, the connection between your computer and the proxy happens over SSH, an encrypted protocol. This prevents wifi sniffers from seeing what you’re doing online.
Start your SSH tunnel
So you’ve got your ssh server setup at your house or workplace. Great! To connect to it we’re going to setup a local proxy server on your client that you’ll be browsing the internet from, which will then “tunnel” web traffic from your local machine to the remote server over SSH. The command to run on your linux / mac client in a terminal window is : ssh -ND 9999 you@example.com
For Windows it’s as simple as browsing to the directory you saved plink to and running
plink.exe -N -D 9999 you@example.com
Of course, you’re going to replace the you with your username on your SSH server and example.com with your server domain name or IP address. What that command does is accept requests from your local machine on port 9999 and hands that request off to your server at example.com for processing.
When you execute either of those commands, you’ll be prompted for your password. After you authenticate, nothing will happen. The -N tells ssh not to open an interactive prompt, so it will just hang there, waiting. That’s exactly what you want.
Set Firefox to use SOCKS proxy
Once your proxy’s up and running, configure Firefox to use it. From Firefox’s Tools menu, choose Options, and from the Advanced section choose the Network tab. Next to “Configure how Firefox connects to the Internet” hit the “Settings” button and enter the SOCKS information, which is the server name (localhost) and the port you used (in the example above, 9999.)
Save those settings and hit up a web page. When it loads, visit http://www.ipchicken.com to see if it’s using your remote ssh server to tunnel traffic. If you are, GOLDEN!
If you feel there’s something I’ve missed, hit me up here (http://www.mattlestock.com)
PS: Remember that you’ll need to open your firewall a bit by cracking open port 9999 on your local machine and port 22 on your server for SSH.
