Tenerifa

2016-02-172016-02-17 by .pQd

i’ve spent two weeks traveling around Tenerifa with my parents. we’ve seen a bit of the commercial-heavy south near Los Cristianos, rocky west coast in Los Gigantes, semi-rural areas of Icod de Vinos, a bit of Puerto de la Cruz and post-volcanic Teide and Puerto de Guimar. our hiking routes – below.

Dell’s 10gbase-t network cards on Intel’s x540 chips

2016-02-122016-03-03 by .pQd

we’re upgrading few servers at work to have 10gbit/s connectivity. to keep things familiar i’ve decided to stick with [power hungry and latency-inducing] cat7 copper cabling and 10gbase-t. there are few dell poweredge r620 and r630 to be upgraded. currently those have proprietary broadcom-based daughter-cards with 4x 1000base-t ports. i preferred to replace them with ...

audible / drm

2015-12-202024-05-27 by .pQd

i’ve made a mistake of buying an audiobook from audible.com. before doing it i’ve briefly checked if the file will be provided in mp3; according to audible.com/sh yes. in reality – no.

mounting partitions from within of the vmware’s .vmdk file or kvm’s qcow2

2015-12-012022-12-13 by .pQd

i’m taking backups of vmware esxi vms weekly using ghettovcb. it has been working greatly for many years. once in a while i need to recover a particular file from particular backup. there’s quicker way than just restoring the whole vm!

10 days in Albania

2015-11-012015-11-01 by .pQd

i’ve spent nearly two weeks traveling around Albania. i’ve started and ended the journey on a Greek island – Corfu [ i could not find any reasonably-priced flight from Berlin to Tirana ] and from there travelled with a ferry to Sarandë.

esxi 6.0: “create virtual machine snapshot” “a general system error occurred”

2015-10-312015-10-31 by .pQd

i’ve upgraded from esxi 5.5 to 6.0 a couple of servers. soon after i’ve discovered that ghettoVCB would fail on some of VMs while it worked fine on the others. i’ve started poking around and found out that for those VMs where backup failed i creation of snapshot would fail with the following error: while ...

“Waiting for TUN/TAP interface to come up” in OpenVPN logs under windows 10

2015-10-102023-01-23 by .pQd

i run windows 10 on one of the computers, it also has a ‘dial up’ openvpn – started from openvpn gui. it worked fine for a few days but then i started to see repeting in the logs and tunnel would not get up for 20-60 seconds. and sometimes even after that the right entries ... Read More

drac5 / 6 with latest java 1.8.60

2015-09-242015-09-24 by .pQd

new java, new headaches. but my colleague figured a way how to get the ip kvm working again with the latest java. here are his findings: ingredients: windows 8.1, j2se 1.8.60, firefox 41 or chrome 45.0.2454.99: go to the Control panel > java in the General tab: Settings > Delete files – mark all the ...

more smaller icons in the windows 8 alt+tab / cool switch

2015-07-242015-07-24 by .pQd

recently i’ve moved from win7 to win8. i tend to have dozens of applications open and the default number of programs displayed after pressing alt+tab in win8 is too low. this registry change brings the win7-alike layout and adds more columns and rows: you might want to log off and log on for all the ...

openvpn point-to-point server listening both on v4 and v6

2015-07-03 by .pQd

at work i have openvpn between OVH dedicated server and our datacenter. due to varying bandwidth we sometimes use udp over ipv6 and sometimes over ipv4 as an encapsulation method. whenever we did the switch we always had to reconfigure both ends of the tunnel. it turns out that with recent openvpns and kernels it’s ...

squid3 no longer working after upgrade to jessie

2015-06-20 by .pQd

on one of the servers i’ve just upgraded to jessie i got my squid3 bricked. i could see the process in ps, yet it did not listen on tcp/3128: restarting it did not give anything interesting in /var/log/squid3/cache.log: after a while of clueless googling i thought – maybe there’s some problem with communication over loopback. ...

audit/access logs in samba

2015-05-07 by .pQd

i’ve ‘convinced’ my samba running under debian wheezy/jessie to provide me access audit logs without being too verbose. here’s how.

upgrade from wordpress 4.1.x to 4.2.x broke my menu editor

2015-05-032015-05-03 by .pQd

i’ve done a routine upgrade of wordpress 4.1.x to 4.2 and later 4.2.1. all seemed fine until the day i wanted to manually adjust the menu structure using wp-admin > appearance > menus. each attempt of saving my menu resulted in it being wiped out completely

openvpn – TLS Error: local/remote TLS keys are out of sync and VPN restarts

2015-04-302015-05-03 by .pQd

one day an openvpn that used to carry traffic for the last 7 years started to misbehave. openvpn’s own built in watchdog was restarting it every few minutes. one of the tunnels endpoints – a- is behind NAT that we don’t control, another – b – is a host with public ip address.

“Error when reading form SSL socket connection” when accessing DRAC5

2015-02-192015-02-19 by .pQd

we still have bunch of servers with DRAC5 cards. after upgrade to java 8u31 java-based kvm console stopped working. it gives: “error when reading from SSL socket connection.” message box during startup and that’s it.

Taling Chan floating market, Bangkok hike

2015-02-152015-02-15 by .pQd

i stayed in Bangkok for 3 nights. i took one-day trip to Ayutthaya and have spent rest of the time hiking around. the longest hike i took was to Taling Chan floating market. as in many other cases it was more about the way there and back than the destination itself.

Ayutthaya

2015-02-152015-02-15 by .pQd

as in 2012 i’ve done a one-day trip to Ayutthaya. it was very much worth repeating and getting away from noisy Bangkok.

Chumphon, Hua Hin

2015-02-122015-02-12 by .pQd

on my way from Koh Tao to Bangkok i’ve stayed for one night at Chumphon and then Hua Hin. the first one was totally not-touristy, second – quite opposite; i’m glad that i decided not to rush towards Thailand’s capital and visited both.
