Amazon CloudWatch RUM adds support for Interaction to Next Paint (INP) Web Vital

9 May 2025 @ 9:59 pm

Today, CloudWatch RUM, a real-time monitoring service that visualizes and analyzes user interactions with web applications, announces support for Interaction to Next Paint (INP) web vital monitoring. This crucial metric would help customers measure the latency of a page's response to user interactions, offering insights into the end-user experience of their web application. INP is a metric that assesses a page's overall responsiveness to user interactions by observing the latency of all click, tap, and keyboard interactions that occur throughout the lifespan of a user's visit to a page. The final INP value is the longest interaction observed, ignoring outliers. This new metric joins the existing set of core web vitals tracked by CloudWatch RUM. The time series graph for INP allows customers to instantly assess whether page responsiveness is positive, tolerable, or frustrating based on a percentile aggregate of the metric. Furthermore, customers can click on specific data po

Amazon VPC Reachability Analyzer now supports resource exclusion

9 May 2025 @ 5:00 pm

Amazon VPC Reachability Analyzer now supports the ability to exclude network resources when analyzing reachability between a source and destination, providing you greater flexibility to run reachability analyses. VPC Reachability Analyzer is a configuration analysis feature that enables you to check network reachability between a source resource and a destination resource in your virtual private clouds (VPCs). With this launch, you can easily identify an alternative traffic path in your network. For example, if you want to identify any path from your internet gateway to Elastic Network Interfaces (ENIs) that is not passing through the network firewall for inspection, you can specify Network Firewall under resource exclusion and run the reachability analysis. If the analysis returns a reachable path, you know there is an alternative path in your network and ca

How to install KSH on FreeBSD

3 March 2025 @ 11:50 pm

See all FreeBSD related FAQ Installing KSH (KornShell) on FreeBSD can be done with either FreeBSD ports or the pkg command. The ports collection will download the KSH source code, compile it, and install it on the system. The pkg method is easier, and it will download a pre-compiled binary package. Hence, it is recommended for all users. KornShell (KSH) has a long history, and many older Unix systems and scripts rely on it. As a result, KSH remains relevant for maintaining and supporting legacy infrastructure. Large enterprises, especially those with established Unix-based systems, continue to use KSH for scripting and system administration tasks. Some industries where KS

Linux Sed Tutorial: Learn Text Editing with Syntax & Examples

3 March 2025 @ 9:47 am

See all GNU/Linux related FAQ Sed is an acronym for "stream editor." A stream refers to a source or destination for bytes. In other words, sed can read its input from standard input (stdin), apply the specified edits to the stream, and automatically output the results to standard output (stdout). Sed syntax allows an input file to be specified on the command line. However, the syntax does not directly support output file specification; this can be achieved through output redirection or editing files in place while making a backup of the original copy optionally. Sed is one of the most powerful tools on Linux and Unix-like systems. Learning it is worthwhile, so in t

Critical Rsync Vulnerability Requires Immediate Patching on Linux and Unix systems

15 January 2025 @ 6:04 pm

Rsync is a opensource command-line tool in Linux, macOS, *BSD and Unix-like systems that synchronizes files and directories. It is a popular tool for sending or receiving files, making backups, or setting up mirrors. It minimizes data copied by transferring only the changed parts of files, making it faster and more bandwidth-efficient than traditional copying methods provided by tools like sftp or ftp-ssl. Rsync versions 3.3.0 and below has been found with SIX serious vulnerabilities. Attackers could exploit these to leak your data, corrupt your files, or even take over your system. There is a heap-based buffer overflow with a CVSS score of 9.8 that needs to be addressed on both the client and server sides of rsync package. Apart from that info leak via uninitialized stack contents defeats ASLR protection and rsync server can make client write files outside of destination directory using symbolic links.

How to control the SSH multiplexing with the control commands

15 January 2025 @ 8:29 am

See all GNU/Linux related FAQ Multiplexing will boost your SSH connectivity or speed by reusing existing TCP connections to a remote host. This is useful when you frequently connect to the same server using SSH protocol for remote login, server management, using IT automation tools over SSH or even running hourly backups. However, sometimes your SSH command (client) will not respond or get hung up on the session when using multiplexing. Typically, this happens when your public IP changes (IPv4 to IPv6 changes when using DNS names), VPN issues, or firewall cuts connections. Hence, knowing SSH client control commands can save you time and boost your productivity when such gotc

ZFS Raidz Expansion Finally, Here in version 2.3.0

14 January 2025 @ 9:19 am

After years of development and testing, the ZFS raidz expansion is finally here and has been released as part of version 2.3.0. ZFS is a popular file system for Linux and FreeBSD. RAIDz is like RAID 5, which you find with hardware or Linux software raid devices. It protects your data by spreading it across multiple hard disks along with parity information. A raidz device can have single, double, or triple parity to sustain one, two, or three hard disk failures, respectively, without losing any data. Hence, expanding or adding a new HDD is a very handy feature for sysadmins in today's data-sensitive apps. Love this? sudo share_on: Twitter -

Incus is best suited when you need system-level containers that act like traditional VMs and provide a persistent developer experience. On the other hand, Docker containers are ephemeral, i.e., temporary in nature. All files created inside Docker containers are lost when your Docker container is stopped or removed unless you stored them using volumes in different directories outside Docker. Docker is created as a disposable app deployment system. Incus containers are not typically created as disposables, and data is kept inside

SLES 15 unable to change logfile for service

So I tried to mitigate this problem by setting StandardOutput=append:/var/log/myapp and StandardError=append:/var/log/myapp directly in the service file. But for whatever reason the logs are still written to journald instead of this file. Can someone give me assistance?

TP-Link Wifi extender causes duplicate IP reporting [migrated]

11 May 2025 @ 9:50 am

My ISP's wi-fi router is a Huawei one with the IP address of 192.168.100.1 I have a TP-Link TL-WR840N wi-fi in range extender mode installed for a long time. That's the one my laptop is connected to right now. Recently, to cover a low signal area, I installed a TP-Link TL-WA855RE, also in extender mode. My XBox, Android and iPhones in that area work just fine. Laptops in any area do not. They connect to wi-fi but don't get any IP. This laptop just now didn't get one. Double-checking shows that DHCP is enabled only on the Huawei. Checking the laptop logs shows that it does get assigned an IP from the range I've defined, but after a second or so marks it as duplicate. The curios thing is that the log shows that any IP that gets assigned to the laptop is a duplicate for device with one particular MAC; the MAC belonging to the Huawei. To use the laptop, I have to either give it a static IP, or power off the WA855RE. Can't think of any reason why

10 May 2025 @ 8:32 pm

After I installed a fresh Debian 12 on a Dell R430 server I got a Broadcom fiber card. After the boot, the system loaded the bnxt_en driver I can see 2 new interfaces however I am not able to use them. We plugged it to the fibre switch. The green led is slowly blinking in the network card, I am not sure what does that mean... ethtool shows that there is no link detected :( Here are the details: # uname -a Linux fw 6.1.0-34-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.135-1 (2025-04-25) x86_64 GNU/Linux # # lsmod | grep bnx bnxt_en 339968 0 root@fw:~# # ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever 2: ens2f0np0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default

Apache won't proxy to Tomcat 10

I'm installing a JSP webapp on Ubuntu 24.04 using Tomcat 10 and Java 11. The app is designed to have Apache proxy JSP requests to Tomcat via AJP. It has worked with previous versions of Ubuntu, Tomcat and Java going back to at least 2014. When I attempt to access the index page of the app on the new system, the server returns a "503 Service Unavailable" error. As far as I can tell, I'm setting it up exactly like previous instances that have worked. Apache's mod_proxy and mod_ajp are both enabled: $ ls /etc/apache2/mods-enabled | grep "prox" lrwxrwxrwx 1 root root 32 Mar 17 13:02 proxy_ajp.load -> ../mods-available/proxy_ajp.load lrwxrwxrwx 1 root root 28 Mar 17 13:02 proxy.conf -> ../mods-available/proxy.conf lrwxrwxrwx 1 root root 28 Mar 17 13:02 proxy.load -> ../mods-available/proxy.load Tomcat's /etc/tomcat10/server.xml has its AJP Connector enab
