When using X-Chat Aqua on OSX Lion it is possible to get various different errors when making SSL connections to different IRC networks. In this example I was attempting to make a SSL connection to the Freenode IRC network on port 6697. The connection terminated with a SSL error complaining that X-Chat Aqua could not get the local issuer certificate as shown in more detail below.
X-Chat Aqua SSL Connection To Freenode IRC Network Error:
Error Text: Connection failed. Error: unable to get local issuer certificate.? (20)
Resolving this error message is easy by enabling the SSL connection to Freenode to allow invalid SSL certificates which can be done in the Freenode server Connection Options. First open the IRC network Server List by opening X-Chat Aqua, clicking on File in the top navigation bar, and then selecting Server List from the drop down. Once the server list displays scroll down and highlight Freenode, click the Show Details button, and then click the Connection Options tab as shown in the below example image.
X-Chat Server List Connection Options Configuration Window:
Now put a check next to Allow Invalid SSL Certificates as shown in the below example image.
X-Chat Server Connection Options: Allow Invalid SSL Certificates:
Now close X-Chat so the application restarts. You should now be able to make an SSL connection to the Freenode IRC network.

In particular, it addresses the abuse of computer networks as well as privacy and security issues on computer networks.</p> <p>This updated edition is organized into five parts. Part 1 is about digital forensics and covers topics ranging from the use of digital evidence in the courtroom to cybercrime law. Part 2 explores topics such as how digital investigations are conducted, handling a digital crime scene, and investigative reconstruction with digital evidence. Part 3 deals with apprehending offenders, whereas Part 4 focuses on the use of computers in digital investigation. The book concludes with Part 5, which includes the application of forensic science to networks.</p> <p>New to this edition are updated information on dedicated to networked Windows, Unix, and Macintosh computers, as well as Personal Digital Assistants; coverage of developments in related technology and tools; updated language for search warrant and coverage of legal developments in the US impacting computer forensics; and discussion of legislation from other countries to provide international scope. There are detailed case examples that demonstrate key concepts and give students a practical/applied understanding of the topics, along with ancillary materials that include an Instructor\’s Manual and PowerPoint slides.</p> <p>This book will prove valuable to computer forensic students and professionals, lawyers, law enforcement, and government agencies (IRS, FBI, CIA, CCIPS, etc.). </p><ul><li>Named The 2011 Best Digital Forensics Book by <i>InfoSec Reviews</i></li><li>Provides a thorough explanation of how computers & networks function, how they can be involved in crimes, and how they can be used as evidence </li><li>Features coverage of the abuse of computer networks and privacy and security issues on computer networks</li></ul>0Amazon.com Review<p/><SPAN class=h3color><B>Practitioner\’s Tips from <i>Digital Evidence and Computer Crime</i>\’s Chapter on Digital Evidence in the Courtroom</B></SPAN><br> <ul> <p/><li>In practice, many searches are conducted with consent. One of the biggest problems with consensual searches is that digital investigators must cease the search when the owner withdraws consent. However, digital investigators may be able to use the evidence gathered from a consensual search to establish probable cause and obtain a search warrant.</li> <p/><li>Once a search warrant is obtained, there is generally a limited amount of time to execute the search. Therefore, it is prudent to obtain a search warrant only after sufficient preparations have been made to perform the search in the allotted time period. Any evidence obtained under an expired search warrant may not be admissible.</li> <p/><li>Many digital investigators use the terminology “is consistent with” inappropriately to mean that an item of digital evidence might have been due to a certain action or event. For many people, to say that something is consistent with something else means that the two things are identical, without any differences. To avoid confusion, digital investigators are encouraged only to state that something is consistent with something else if the two things are the same and to otherwise use the terminology “is compatible with.”</li> <p/><li>Given the complexity of modern computer systems, it is not unusual for digital investigators to encounter unexpected and undocumented behaviors during a forensic analysis of digital evidence. Such behaviors can cause unwary digital investigators to reach incorrect conclusions that can have a significant impact on a case, sometimes leading to false accusations. Thorough testing with as similar an environment to the original as possible can help avoid such mistakes and resolve differences in interpretation of digital evidence. Provided digital investigators can replicate the actions that led to the digital evidence in question, they can generally agree on what the evidence means. When it is not possible to replicate the exact environment or digital evidence under examination, digital investigators may need to rely on their understanding of the systems involved, which is where differences of opinion can arise.</li> <p/><li>Careful use of language is needed to present digital evidence and associated conclusions as precisely as possible. Imprecise use of language in an expert report can give decision makers the wrong impression or create confusion. Therefore, digital investigators should carefully consider the level of certainty in their conclusions and should qualify their findings and conclusions appropriately.</li> </ul> <table align=\”center\” cellpadding=\”4\” width=\”201\”> <tbody> <tr align=\”center\”> <td><img border=\”0\” src=\”https://images-na.ssl-images-amazon.com/images/G/01/books/stech-ems/Digital-Evidence-and-Computer-Crime-3E-image-9780123742681._V154965471_.jpg\” alt=\”Sample chapter from <i>Digital Evidence and Computer Crime</i>\”/> <div class=\”imageCaption\”><small>Read a sample chapter on genesis and migration from <i>Digital Evidence and Computer Crime</i></small></div> </td> </tr> </tbody> </table>10123742676Handbook of Digital Forensics and Investigation1285060032Guide to Computer Forensics and Investigations (with DVD)0321268172File System Forensic Analysis1586489070Fatal System Error: The Hunt for the New Crime Lords Who Are Bringing Down the Internet1597974234Cyberpower and National Security0470901063EnCase Computer Forensics — The Official EnCE: EnCase Certified Examiner Study Guide0989845117Protecting Our Future: Educating a Cybersecurity Workforce0132564718Network Forensics: Tracking Hackers through Cyberspace0470931663Computer Forensics JumpStart1593272901Practical Malware Analysis: The Hands-On Guide to Dissecting Malicious Software3705Internet, Groupware, & Telecommunications3652Networking & Cloud Computing5Computers & Technology1000Subjects1283155Books3740Networks, Protocols & APIs3742COM & DCOM3743CORBA3744ISDN3745LAN69960LDAP3747Networks3749ODBC170900SNMP3624TCP-IP132568011WAN3652Networking & Cloud Computing5Computers & Technology1000Subjects1283155Books3641Privacy & Online Safety377560011Security & Encryption5Computers & Technology1000Subjects1283155Books11173Forensic Psychology11119Psychology & Counseling10Health, Fitness & Dieting1000Subjects1283155Books11007Forensic Science173489Criminal Law10777Law1000Subjects1283155Books10873Evidence173489Criminal Law10777Law1000Subjects1283155Books10907Law Enforcement173489Criminal Law10777Law1000Subjects1283155Books6511987011Forensic Psychology6511980011Psychology173514Medical Books1000Subjects1283155Books5571262011Law Enforcement5571258011Specific Topics5571255011Politics & Government3377866011Politics & Social Sciences1000Subjects1283155Books491302Networking468204Computer Science465600New, Used & Rental Textbooks2349030011Specialty Boutique283155Books468222Law491506Business Law491510Constitutional Law491512Criminal Law491516Legal Reference491514Tax Law465600New, Used & Rental Textbooks2349030011Specialty Boutique283155Books491490Psychology491492Clinical Psychology684296011Cognitive Psychology491496Developmental Psychology684297011Neuropsychology684298011Psychopathology491494Psychotherapy468214Social Sciences465600New, Used & Rental Textbooks2349030011Specialty Boutique283155Books
I live in the SoBro neighborhood of Louisville, KY with my daughter and our cat Apollo. I enjoy being challenged by technology problems and am fortunate enough to get paid to solve them.
