Life is easy with good tools

Get the latest open source tools for z/OS. Life is easy.

Photo by Matthias Speicher on Unsplash A group of us have been working on porting the latest Open Source tools to z/OS. I gave an intro to the z/OS Open Source Community a few months ago, and now I’d like to provide a simple example of how useful these tools can be. A very common problem is to perform a search and replace across a set of files in a directory tree. Maybe your manager said the…

Web site: www.localareasecurity.com (not active) Origin: USA Category: Security Desktop environment: Fluxbox Architecture: x86 Based on: Knoppix Wikipedia: Media: Live The last version | Released: 0.5 | March 6, 2004

Local Area Security (L.A.S.) – live-CD Linux distribution for information security professionals. It contains over 250 security tools including all the usual suspects (Nmap, Nessus, etc.) as well as many other great tools less well known. The ISO images are meant to be burned on 185MB and 210MB miniCDs which they update around twice a month. The distribution was available in 2 different versions of L.A.S. to fit two specific needs – MAIN and SECSERV.

The project was started in 2002 to research information security related topics. During that time there was no real live-CD toolkit focused on information security. So Jascha, the project founder built one from a stripped down version of Knoppix called Model-K. Both of which were built from Debian Linux. Up until version 0.4 L.A.S. Linux was command line only. After that, FluxBox was added as the desktop since it is light weight and very feature filled.

A few of the tools that wewe available in the distribution: etherape, mozillafirebird, argus-server, argus-client, arpwatch, bfbtester, cabextract, cflow, dlint, farpd, recover, gtkrecover, nasm, nast, strace, ltrace, sudo,valgrind, pnscan, isic, splint, sendip, scli, scanssh, rarpd, wellenreiter,router-audit-tool, httpush, bass, scansort, scanerrlog, idsa / idsaguardgtk, crank (for fun), ccrypt, ntfstools, pasmal, bruth, hlfl, less, smbfs, smstools, LinNeighborhood, snmp, snmpd, driftnet, Dillo, admsmp, admsnmp,arptool, di, hammerhead, flawfinder, foremost, md5deep, binutils, findutils,file, gall, libpst, libdbx, rda, ntreg, memfetch, stegdetect, mkpersistenthome, mkdosswap, pv, cscope, scanlogd, cgrep, bsed, vlad, warscan, zodiac, angst, hackbot, mieliekoek.pl, screamingcobra.pl, cmospwd, macchanger, vomit, atmelwlandriver, wlcardconfig, sshstart-knoppix.

Welcome to our guide on how to install Netdata on RHEL 8 / CentOS 8. Netdata is a powerful real-time and distributed health and performance monitoring tool for Applications and infrastructure systems. Netdata can be used on physical servers, Virtual Machines, containers, and IoT devices. It gives you modern interactive web dashboards for viewing your server metrics with support for various data stores for persistent storage. Features of netdata Here are the key features of Netdata monitoring tool. Auto-scaling of chart units IP access lists for filtering access to netdata Enhanced VMs and containers monitoring Highlighted time-frames across all charts of the dashboard Dashboard snapshots, for loading/saving of selected time-frames Timezone conversion at the dashboard to allow comparing charts with server logs Zero maintenance, configuration, and dependencies It is easily customizable, extensible, and embeddable Scales to infinity Time-series back-ends supported – it can archive its metrics on graphite, opentsdb, Prometheus, JSON document DBs, in the same or lower detail. Install Netdata on RHEL 8 / CentOS 8 We’re going to build and install Netdata on RHEL 8 / CentOS 8 from source. Let’s kickoff by ensuring all dependencies are installed. Login to your server run below commands. sudo dnf -y install git zlib-devel libuuid-devel libmnl gcc make git autoconf automake pkgconfig curl findutils Next is to clone Netdata code from Github. git clone https://github.com/netdata/netdata.git --depth=100 Start the build and installation of Netdata on RHEL 8 / CentOS 8 $ cd netdata/ $ sudo ./netdata-installer.sh ^ |.-. .-. .-. .-. . netdata | '-' '-' '-' '-' real-time performance monitoring, done right! +----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+---> You are about to build and install netdata to your system.

シェルスクリプトで名前にスペース(空白)を含むファイルがxargsでうまく処理できない場合の対処

ファイル名にスペースが含まれている場合のあるある記事ですが、findだけでなくgrepやtarについても触れてみました。 #プログラミング初心者 #プログラミング初学者 #shell #shellscript #bash

はじめに チームメンバから「名前にスペースを含むファイルをxargsでうまく取り扱えない」という相談を受けました。 調べたらすぐに解決する あれ だと思ったのですが、 find ではなく grep の実行結果を xargs に渡していたので、なるほどあまり見ないケースだなと思ったついでにエントリをまとめました。 検証環境 $ uname -moi x86_64 MacBookPro16,1 Darwin $ bash -version | head -n 1 GNU bash, バージョン 5.0.18(1)-release (x86_64-apple-darwin19.5.0) $ grep --version grep (BSD grep) 2.5.1-FreeBSD $ find --version find (GNU findutils)…

xargsにパイプで渡した標準入力が空だった場合にエラーが出ないようにする

はじめに xargs コマンドは非常に便利です。 パイプでつなぎ、前のコマンドを1つずつ(あるいはいくつかの束ずつ)処理していくときに 簡潔に記述できかつ高速です。 ただ、パイプの前のコマンドの実行結果が空になると想定しない挙動をする場合があります。 問題と対処について紹介します。 検証環境 $ uname -moi x86_64 x86_64 GNU/Linux $ bash -version | head -n 1 GNU bash, version 4.2.46(2)-release (x86_64-redhat-linux-gnu) $ xargs --version | head -n 1 xargs (GNU findutils) 4.5.11 何も考慮せず xargs を使ってみる。 なにか具体的な例を考えたいので、 seq コマンドで生成した数列を xargs…

GCPのGoogle Container Registryのイメージを一括削除する方法

はじめに

GCP上の Google Container Registry 内に不要なDockerイメージがあるため、削除したいと思いました。

Dockerイメージを削除するためには、すべてのタグ（というかハッシュ。ビルド履歴）を削除する必要がありmさう。

対象のDockerイメージに4000以上のタグが付与されているため、できる限り一括かつ並列で削除擦る方法を探してみました。
