These slowness issues and complaints have sometimes come up in my organization and executive directors are never happy when these escalations come to them.

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

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

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.

If a client wants to get an IP address belonging to a subdomain - say example.com - he will first get the hostname of the nameserver for example.com - say ns1.example.com - and then perform a second query to get the IP of ns1.example.com (which will usually be answered by ns1.com as well, using a glue record). To avoid performing two queries, this IP might actually be transmitted in the ADDITIONAL field of the first reply. One of the answers to the question mentions at the beginning explains that the advantage of this approach is that a change of the IP address of the nameserver ns1.example.com does

How can I locally verify that Intune policies were applied on a managed device

14 October 2025 @ 3:09 pm

Our environment uses Intune to manage the configuration settings of endpoints. I am trying to troubleshoot why Defender for Cloud (DC) shows certain settings as not applied. Currently investigating an Attack Surface Reduction (ASR) rule. I have verified that the specific ASR rule has been set to "block" in the ASR policy. The ASR policy includes the relevant group. The user is in the relevant group. And the policy displays as successfully applied. Is it possible to locally view which policies and settings were applied, when they were applied, and any errors in their application? I have tried using gpresult /v which gives very little actionable information. I have tried to include every output below. Recommended remediation in DC Block executable files from running unless they meet a prevalence, age, or trusted list criterion  Remediation required Description Attack Surface Reduction (ASR) rules ar

DNS lookup fails even though an A record exists in Oracle Cloud DNS for it in the public zone

14 October 2025 @ 3:16 am

I have an OCI tenancy with a compute instance in the public subnet. I purchased a donraikes.com domain through godaddy.com. I associated donraikes.com with my tenancy by creating a public zone in the tenancy and connecting the nameservers with the ns entries at godaddy. I installed apache httpd onto the compute instance and opened ports 80 and 443 on the firewall. I added an "A" record in my zone for devserver.donraikes.com, but opening a browser to devserver.donraikes.com returns a "server not found" error. When I use nslookup from wsl I get server unknown and the same with the host command. I used OCI cli to download the zone file for donraikes.com and see the "A" record in it resolvable to the correct IP address. I can open my web browser to the ip address and the index.html file opens just fine. Why isn't the A record for the host accessible publicly, outside of OCI? How can I troublesho

nginx rewrite remove all arguments from uri

13 October 2025 @ 9:47 pm

I've been spinning my wheels for a month on the following problem. Nothing I have tried from reading lots of answers from here and on stack exchange about rewriting queries has worked. Google has cached many urls with query parameters and I've been trying to remove the query parameters from the urls. example: https://circadian.com/blog/12-hour-shifts?tmpl=component&print=1&format=print I'm trying to get that re-written to https://circadian.com/blog/12-hour-shifts Any help here would be appreciated. Thanks
