Linux.

Guys, I need some inspiration. How are you dealing with memory leaks, i. .e identifying which component of the system is leaking memory?

Regular method of dumping ps aux sorted by virtual memory usage is not working as all the processes are using the same amount of memory all the time. This is XEN dom0 memory leak, and I have no more ideas what to do.
Is it possible that guests could be eating the dom0 memory?

Do devrant ship gree stickers to Lithuania?

I did not receive any reply since 2017 September :(

fuck oracle. fuck my company.

Using Oracle VM Manager/Servers to host Oracle Phone transfer solution without support coverage from Oracle.

Requiring Unix sysadmins to update to latest release and not telling that we do not have coverage from Oracle if anything goes wrong.

Gues what.. We've updated to Oracle VM Manager/Server 3.4.5 which was released this year and it uses fucking XEN hypervisor version 4.4.4 which has been deprecated and dead since who knows when. Latest release of XEN is 4.11. But that is not an issue, whatever, enterprise, legacy software, etc.

This fucking update introduced memory leak on the hypervisor which has been reported as per xen 4.4.4 history. Furthermore, we have no support from Oracle which means that I have to dig through mailing lists and limited information on the net since oracle has freakin support wall on nearly each of the major bugs found on that shitty software.

I have no idea whether any newer version of xen will work with that old Oracle Linux kernel or not.

Furthermore, Oracle provided great documentation on how to rollback the fcking update. Reinstall the hypervisor. Riiiight. XEN does not have export/import feature.

eh

What do you use for performance monitoring on your infrastructure?

My company uses zabbix, OpenNMS and Nagios to monitor different parts of our infrastructure (from shared web hosting to OCCAS to IPTV to FutureVoice to Atlassian servers) but has no real-time performance checks.

I’ve set netdata master with prometheus backlog and grafana dashboards to monitor different metrics, however I am not sure whether any better approach could be done. Any suggestions?

Just setup an IPsec tunnel and route 192.168.50.0/24 to 192.168.0.0/16 over that tunnel on phase2. We will be able to see 192.168.50.6 machine from 192.168.0.0/16 remote subnet.

Do it.

Why we cannot send ICMP echo from local subnet machine to another machine in same subnet??? Also remote subnet hits only the BSD machine it does not go further. Whyy

I know I should have not done it but SDM and my manager insisted to do so... And now they expect me to fix time outs when remote subnet belongs to different company.

Hello my Friends.

TL;DR i meditate as I draw, here’s the result. What about you?!

Does any of you exercise on any kind of meditation? Not the popular meditation forms, more alternative meditation? I. E. walking meditation, dancing meditation, reading medidation, etc. ? Remember, it’s all about being here and now and letting go of any pre-programmed thoughts, right?

I myself, have a ritual which is performes once-twice a year. I call it drawing meditation. When daylight ends, and the moon rises, I sit at my desk in a dark room with one light, which is hanging aboce the white sheet of paper. I take black pencil, turn on some music mildly and turn off my thought receiving part of the brain. I hear every thought which is passing by, but I have no attachment to it. My hands are drawing, without my interception. It feels amazing, and I believe this method helps me to clean up some space in subconscious file system.

This activity of mine, takes strangly short/long time. Once I’ve sat for about 16hours, once 6hours.

Furthermore, I’m always amazed by the abstract art pieces which are the end result. I’m attaching the image of the last drawing made in this way to the post.

Can I hear what you see in it?

Was invited to interview by agent for 1yr contract position. Was accepted for permament position with bigger salary instead. Now I’m an Unix Infrastructure Engineer

Oh boy, my fellow devRanters, I just signed an 4 digit monthly salary (that's a lot in Lithuania) job contract, I'm a future Unix infrastructure engineer :o

As per original concept of ranting, it's been almost two months since I wrote for the stickers and didn't get a reply >:(

My girlfriends mom asked whether I could fix her coworkers laptop. She claimed that it had viruses installed and laptop is laggy..

So... I got that laptop just now, got home and turned it on. It doesn't have WiFi drivers installed and I do not have any free Ethernet cable right now.

About the lags... Well you won't believe how many custom tool bars and security programs there were. McAffe, AVG, ESET and some Russian made firewall which asks for license key every 5mins.

And she asked me to reinstall windows and keep every file of hers, and she didn't bother to point which files of 300gb of photos/videos/docs are worth keeping and which are not.. HDD is 300GB :A fuck me

P. S. Since it's my first rant I can say ranting helps a lot to calm down
