Configuring rsyslog to rotate log files from log messages streamed to it from a Systemd service

Posted on by rchapin

In general, I have moved to writing all of my applications to write their log output to STDOUT. This makes running them on the command line, in an IDE, on a bare metal box, VM, or in a container completely decoupled from how you store and view the logs. No more having multiple logging configs for each flavor of deployment.

In this particular case, I am running an application in a container (but it isn’t necessary that it is in → Continue reading “Configuring rsyslog to rotate log files from log messages streamed to it from a Systemd service”

If you are setting up Thunderbird to use your Gmail account you may find that when Thunderbird opens a new window to a Google web portal into which you are to provide your email address and password that it will keep asking you over and over again for your email and never enable to you to enter the password.

How to Find Ingested Foreign Objects in Poop

Posted on by rchapin

Admittedly, not the most savory subject. But, for those of us with pets and/or children it is sometimes a necessity to try to find a previously ingested foreign object in feces to make sure that it does not cause medical problems in the person or animal that has accidentally eaten it.

Recently, we thought our dog had eaten a relatively small magnet and figured that we would have to be checking his feces over the next few days to ensure → Continue reading “How to Find Ingested Foreign Objects in Poop”

Edit a Range of Lines Using sed

Posted on by rchapin

Let’s say that you have a range of lines in a source file (lines 11 – 17) that you want to comment out with a ‘#’ and a space character before the line.

To do that, you would use sed, specifying a range of lines and then specify a replacement command with a capture group as follows:

sed '11,17{s/\(\w\)/\# \1/}' filename.py

Mocking an HTTPS RESTful endpoint with Netcat

Posted on by rchapin

Netcat is generally known as a TCP/IP Swiss Army Knife and is incredibly helpful for both debugging and mocking up network services

Following is an example on how to setup a mock RESTful service that communicates over HTTPS.

On the “server” side, run the following command.  The -l command instructs Netcat to listen.

while true; do { echo -e “HTTP/1.1 200 OK\r\n$(date)\r\n\r\n<h1>hello world from $(hostname) on $(date)</h1>” |  nc -vl –ssl 8080; } done

On the “client” side, run the → Continue reading “Mocking an HTTPS RESTful endpoint with Netcat”

Test Network Speed of Ethernet Ports

Posted on by rchapin

If you have just bought a new (to you) nic card or other networking device and want to test that all of the ports can pass traffic at the expected rate, as long as you have nc and the firewall ports open on a “server” with a known good nic and have nc installed on your “client” device that you want to test it is very easy to test.

Of course, if you are testing a switch itself, then it → Continue reading “Test Network Speed of Ethernet Ports”
