The lost case of Viber support

Time for commercials: two years ago, lured into by a very influential person in my life 🙂 I installed Viber app on my phone; soon after the installation, I started buying those stickers for the app, only to end up with more than 100 EUR worth of them nowadays. On my Android phone those stickers would work more-or-less OK all of the time. Also, synchronising those stickers on an Android tablet worked just fine. Synchronising and using those stickers worked just fine for any linux (Ubuntu, Debian, Fedora) I had been using meanwhile, as well as for a Mac OS Sierra on a MacBook Pro 2017. Until one day in December that I could get no synchronisation at the laptops any more. At first, I thought that is a general problem, and I waited a week or two to see if that will be resolved with one of the updates, but then it become clear it will not be sorted without an action from my side – so I opened a ticket.

Kyocera FS 1040 printer not working

Have you tried to turn it off, and on again?” is still a preferred method in IT?

CentOS 7 and IPV6_DEFAULTGW prefixlen

Just a brief side-note for CentOS’ /etc/sysconfig/network-scripts/ifcfg-device IPV6_DEFAULTGW parameter – it does not accept the prefixlen suffix, like the DNS, or IPV6ADDR parameters! In other words, if you do put there something like “/64” (presumably) suffix at the end of your address in IPV6_DEFAULTGW parameter, the

netstat -rn -A inet6

will not display the IPv6 gateway, telling you that the system will not know how to reach the ipv6 Internet.

Not too intuitive, if you ask me but that is what it is…
