I have worked with Redhat for about 6 years now.
I know there is SOOOOO Much I do not know.
I have my RHCSA and am thinking about going for RHCE.
I am enjoying the act of finally getting to learn Ansible.
Looking forward to learning from all and maybe helping some.

Hi All,

So I am trying to post a blog on some useful information regarding some of the Juniper MX routing engines (RE)'s maximum capabilities in terms of how many IPv4 and IPv6 routing table entries they can handle.

I know I am not explaining every clearly right now. I've attached a file for your review.
I hope this file will then make sense. Some of the info. I have on it may even not be correct.

I have been trying to look up informations online, but nothing useful. And the Juniper site does not really provide this kind of info either.

I would really appreciate it if any of you know any sites that I can find this kind of info.

Thanks again,
Denny

# docker -v
Docker version 24.0.6, build ed223bc How is it please possible Ubuntu docker is missing some commands (compared to Devuan) although it is same version as in Devuan ?

I am writing a java app using vscode on linux mint 21. Trying to connect to a local mysql database i get the error "java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/mydb".I installed the mysql-connector-j_8.1.0-1debian11_all.deb package i found at https://dev.mysql.com/downloads/connector/j/ (choosing debian linux as os) and than linked both
mysql-connector-j-8.1.0.jar
mysql-connector-java-8.1.0.jar
to the reference library of my project in vscode.

Also tried the "platform indipendent" jar.

The url should be correct, so is there anything else i should do?

Edit:

i used the command

export CLASSPATH=/usr/share/java/mysql-connector-j-8.1.0.jar:$CLASSPATH

but still get the error

Re-Edit:

it's fine if i include the -classpath command line.

At this point the question would be:

How do i avoid to manually add the -classpath command?

i have a cheap 2 button mouse [maxxter wireless optical mouse ACT MUS-002] with scroll wheel.
When scroll wheel is pressed it acts like the left mouse button/enter key?
When scrolling in a browser, it adds web pages to my browsers' top row, ultimately bogging my computer processor.
can i disable this function whilst keeping the scroll wheel, even with an on screen toggle icon?
i don't know if the signal is unique, or do i cut some wires in the mouse? pls advise.
thx

This doesn't affect Slackware provided kernels, but may affect those who roll their own...

I run slarm64 (an ARM64 version of Slackware) on a Pi 400. It uses cutting edge kernels, currently up at 6.5. A few upgrades ago, my dvb dongle stopped working. While chasing the problem, I found this: https://lore.kernel.org/stable/20230...d-d6bc@gregkh/

It looks like it affects 130 devices, so if you've been having issues with your own kernels, have a look at the list in this thread!

This may affect other modules as well....

A while back, my DVB Pi-hat (Sony cxd2880) stopped working. I found this in dmesg:
Code: dmesg | grep cxd2880
[    3.628383] failing symbol_get of non-GPLONLY symbol cxd2880_attach.
[    3.628412] DVB: Unable to find symbol cxd2880_attach()
[    3.628419] cxd2880_spi: cxd2880_spi_probe: cxd2880_attach failed Googling for it, I found this:

https://lore.kernel.org/stable/20230...d-d6bc@gregkh/

I think its been around longer than they realise, but at least they are now aware. There is a list of devices affected in that thread - about 130 of them!

Just a "heads up" for anyone having a similar issue.

The only solution at present is to revert to a (much) earlier kernel...
