xplico pcap File Upload Fails

I have been playing around with xplico which is a NFAT (Network Forensics Analysis Tool) tool included in Backtrack Linux. Pretty cool application though there are some things I am still figuring out or may be caused by the version be older in Backtrack. One of the main items where I could see new users to Xplico running into is actually noted numerous times on Xplico’s website and so I simply wanted to expand on what has already been noted there. If you are having issues uploading pcap files via the Xplico web interface then it is likely related to the size of the pcap file and the size that the Apache web server will accept. Use the information below to modify the web server configuration to allow larger files to be uploaded.

WordPress Post Comment Error – Unreadable Captcha Token File

After upgrading a bunch of WordPress plugins on a site I noticed that comments were not functional on my site for users that were not logged in. This can always be tricky because if someone reports comments not working to the WordPress site administrator they likely will be logged in when they test the comments and think there is nothing wrong. Anyhow if comments are throwing an error and you have the SI Captcha Anti-SPAM WordPress plugin installed then the below content will assist you to resolve the problem.

svn co Error: Server certificate verification failed: issuer is not trusted

When attempting to sync a repo to a server or to your desktop you will receive an error if the certificate being used to protect the HTTPS repository URL is not issued by the proper authority. Many companies generate their own certificates for repository URL’s especially if the repository is primary used internally. In this example I was attempting to sync a repository using SVN to a folder on the desktop of my Macbook Pro running OSX Mountain Lion. Below I describe the error in more detail followed by resolution to the svn certificate error.

The operation can’t be completed because you don’t have permission to access some of the items

Ever attempt to delete the Trash on OSX and run into an error that says you can’t complete the operation because you don’t have permissions to access some of the items? I am not sure how often this will happen to the average user that wouldn’t already know how to resolve the problem since the chances are high that the file or files created with different permissions required you to change to the root user in the first place. Anyhow below is a better description of the issue along with a screenshot followed by how to resolve the problem emptying your Trash on your Mac.

Luckily I had run into this exact error awhile back and knew exactly where the problem was. Below I describe the error in more detail and provide resolution to the issue.
