It is highly recommended that you have at least Perl version 5.004. You can get the latest perl version from http://cpan.org/src/. Try the direct download link http://cpan.org/src/stable.tar.gz. You can get Perl documentation from the same location (although copious documentation is included in the downloaded Perl distribution). 1.3 CPAN Downloads You can download most of the Perl modules from CPAN. There are many mirrors of this site. The main site’s URL is http://cpan.org/. You may want to search the Perl modules database by using http://search.cpan.org/. Either use the search form, or type in the name of the package the module is distributed in. For example if you are looking for Apache::DumpHeaders, you can type: http://search.cpan.org/search?dist=Apache-DumpHeaders . 1.4 Apache Get the latest Apache webserver and documentation from http://httpd.apache.org. Try the direct download link http://httpd.apache.org/dist/. 1.5 Squid - Internet Object Cache http://www.squid-cache.org/ Squid Linux 2.x Redhat RPMs : http://home.earthlink.net/~intrep/linux/ 1.6 thttpd - tiny/turbo/throttling HTTP server http://www.acme.com/software/thttpd/ 1.7 mod_proxy_add_forward Ask Bjoern Hansen has written the mod_proxy_add_forward.c module for Apache that sets the X-Forwarded-For field when doing a ProxyPass, similar to what Squid does. -

Authenticated Encryption in SSH
Authenticated Encryption in SSH Kenny Paterson Information Security Group @kennyog; www.isg.rhul.ac.uk/~kp Overview (both lectures) • Secure channels and their properties • AEAD (revision) • AEAD ≠ secure channel – the [APW09] attack on SSH • The state of AEAD in SSH today • A new attack on CBC-mode in OpenSSH • Security analysis of other SSH and OpenSSH modes – CTR, ChaChaPoly, gEtM, AES-GCM. 2 Secure channels and their properties Why do we need secure channels? • Secure communications is the most common real- world application of cryptography today. • Secure communications systems are extremely widely-deployed in practice: • SSL/TLS, DTLS, IPsec, SSH, OpenVPN,… • WEP/WPA/WPA2 • GSM/UMTS/4g/LTE • Cryptocat, OTR, SilentCircle • OpenPGP, iMessage, Telegram, Signal, and a thousand other messaging apps • QUIC, MinimalT, TCPcrypt 4 Security properties • Confidentiality – privacy for data • Integrity – detection of data modification • Authenticity – assurance concerning the source of data 5 Some less obvious security properties • Anti-replay • Detection that messages have been repeated. • Detection of deletion • Detection that messages have been deleted by the adversary or dropped by the network. • Detection of re-0rdering • Ensuring that the relative order of messages in each direction on the secure channel is preserved. • Possibly re-ordering the event of violation. • Prevention of traffic-analysis. • Using traffic padding and length-hiding techniques. 6 Possible functionality requirements • Speedy • Low-memory • On-line/parallelisable crypto-operations • Performance is heavily hardware-dependent. • May have different algorithms for different platforms. • IPR-friendly • This issue has slowed down adoption of many otherwise good algorithms, e.g. OCB. • Easy to implement • Without introducing any side-channels. -
Deviceside Software Update Strategies for Automotive Grade Linux
Deviceside Software Update Strategies for Automotive Grade Linux Konsulko Group, sponsored by ATS Advanced Telematic Systems GmbH Overview This whitepaper explores the area of software update strategies for devices running Automotive Grade Linux. The starting point is understanding several key use cases for updating software in an AGL1 system. Several open source deviceside software update mechanisms are compared with a focus on their ability to meet the stated use cases. Finally, recommendations are made for an approach that can be implemented for inclusion in AGL. Use Cases and Requirements The topic of software update on any computing device is very broad and can only be examined properly by narrowing the scope of the system, operating conditions, and the policies established for executing a software update. The following sections describe the use cases considered when evaluating the various mechanisms that could be employed in an AGL software update strategy. System Description AGL systems include both IVI2 and ADAS3 devices that run Linux on at least one processor in the system. The complete IVI or ADAS system is not necessarily limited to a single processing node, but is normally part of a larger network that includes a number of ECU4 nodes throughout the automobile. Due to this distributed architecture it is often necessary to update software on 1 Automotive Grade Linux (https://www.automotivelinux.org/aglspecification) 2 InVehicle Infotainment 3 Advanced Driver Assistance System 4 Electronic Control Unit Copyright 2016 Konsulko Group and ATS Advanced Telematic Systems GmbH CC BYSA 3.0 US (https://creativecommons.org/licenses/bysa/3.0/us/) the ECUs as well as the node running AGL. -

An Analysis of Python's Topics, Trends, and Technologies Through Mining Stack Overflow Discussions
1 An Analysis of Python’s Topics, Trends, and Technologies Through Mining Stack Overflow Discussions Hamed Tahmooresi, Abbas Heydarnoori, and Alireza Aghamohammadi F Abstract—Python is a popular, widely used, and general-purpose pro- (LDA) [3] to categorize discussions in specific areas such gramming language. In spite of its ever-growing community, researchers as web programming [4], mobile application development [5], have not performed much analysis on Python’s topics, trends, and tech- security [6], and blockchain [7]. However, none of them has nologies which provides insights for developers about Python commu- focused on Python. In this study, we shed light on the nity trends and main issues. In this article, we examine the main topics Python’s main areas of discussion through mining 2 461 876 related to this language being discussed by developers on one of the most popular Q&A websites, Stack Overflow, as well as temporal trends posts, from August 2008 to January 2019, using LDA based through mining 2 461 876 posts. To be more useful for the software topic modeling . We also analyze the temporal trends of engineers, we study what Python provides as the alternative to popular the extracted topics to find out how the developers’ interest technologies offered by common programming languages like Java. is changing over the time. After explaining the topics and Our results indicate that discussions about Python standard features, trends of Python, we investigate the technologies offered web programming, and scientific programming 1 are the most popular by Python, which are not properly revealed by the topic areas in the Python community. -
