IBM to Represent Redli

Redli is a new command line interface for Redis database 
27 August 2018   712

IBM Compose, which develops a secure cloud environment for various databases, introduced the open source Redli command-line interface (CLI) to the non-relational high-performance Redis DBMS. A special feature of the client is a convenient connection to servers protected by TLS / SSL security protocols.

The developers argue that working with secure Redis servers using the default command-line client, redis-cli, is a nuisance. For each connection, you need to configure the Stunnel utility, which provides a secure connection, send the server to the local port and, finally, connect to this port using redis-cli.

Authors of Redli tried to solve the problem using the script stunredis for automated tuning of tunnels on demand, but it did not always work correctly.

IBM specialists wrote a CLI client in the Go programming language using the Redigo command line flags, the interactive library, and JSON from the Redis documentation. Among the key features of Redli there are:

  • rediss schemes in unified resource identifiers (URIs) to fully specify a connection to the Redis database;
  • --tls flag for activation of TLS / SSL protocols, as well as-h, -p and -a, which are similar to those in redis-cli;
  • the --long flag indicating the full server name and port in the string;
  • help with help on each command;
  • completion of the tab for commands;
  • history of each session;
  • All the Redis supported teams, including the future ones;
  • immediate execution of operations Redis, written immediately after the command Redli.

According to the developers, due to the principles of the interface, it does not yet support the special flags of debugging and reports --stat,--latency and --bigkeys. This will be fixed in future updates.

In February 2017, due to problems with Redis clusters, the version control system GitLab failed for half an hour after an unsuccessful update attempt.

Porteus Kiosk 4.8.0 to be Available

Porteus Kiosk is OS designed for stand-alone kiosks, self-service terminals and display booth 
22 January 2019   100

The release of the Porteus Kiosk 4.8.0 distribution kit, based on Gentoo, is designed to equip stand-alone internet kiosks, display booths and self-service terminals. The boot image of the distribution is 93 MB.

The basic build includes only the minimum set of components required to launch a web browser (Firefox and Chrome are supported), which is reduced in its capabilities to prevent unwanted activity in the system (for example, setting changes are not allowed, application download / install is blocked, access to selected pages). Additionally, specialized Cloud assemblies are offered for comfortable work with web applications (Google Apps, Jolicloud, OwnCloud, Dropbox) and ThinClient for working as a thin client (Citrix, RDP, NX, VNC and SSH) and Server for managing a network of kiosks.

Setup is done through a special wizard, which is combined with the installer and allows you to prepare a customized version of the distribution for placement on a USB Flash or hard drive. For example, you can set a default page, define a white list of allowed sites, set a password for the guest login, define an inactivity timeout to end a session, change the background image, adjust the browser design, add additional plug-ins, enable wireless network support, configure keyboard layout switching and more. 

When loading, verification of system components by checksums is performed, and the system image is mounted in read-only mode. Updates are installed automatically using the mechanism of formation and atomic replacement of the system image as a whole. It is possible to centrally configure a group of typical Internet kiosks remotely with configuration loading over the network. Due to the small size, the default distribution is loaded entirely into RAM, which allows to significantly increase the speed of work.
