net::ERR_NAME_NOT_RESOLVED reiskia, kad turi network problemu, o butent DNS.
Internetas veikia ? gali parasyti sias komandas (rasau ne viena, nes ne visos distros turi tokias komandas)
Patikrinti ar dns veikia:

dig +short s.ytimg.com

host s.ytimg.com

grep nameserver /etc/resolv.conf

Truputi keista, nezinau ka jau Ubuntu ten pakeites
Pagal ideja neturetu veikti internetas at all, na bet daleiskim naudoja kazka kito nei kitos distros... Gal dnsmasq, ar panasu dns toolza kuris taip keistai veikia.

Gali pameginti googles DNS serverius, tam tereiks pakeisti /etc/resolv.conf faile nameservers. pvz taip:

nameserver 127.0.0.1
nameserver 8.8.8.8
nameserver 8.8.4.4

Pats pirmas bus 127.0.0.1 (toks koks yra dabar), todel neturetu del to kilti jokiu problemu. Pries keisdamas failus esancius /etc butinai sukurk ju kopijas.

Prie to pacio parasysiu paprasta buda kaip salinti reklamas bei pagreitinti "interneta".
Pirma tam reikes dnsmasq (Small forwarding/caching DNS server) kuri gauti galima parasius sia komanda:

sudo apt-get install dnsmasq

Toliau reikes sukurti nauja faila /etc/dnsmasq.conf, tik butinai sukurkit kopija jo ir pakeiskit vardenis i jusu user name.

mv /etc/dnsmasq.conf /etc/dnsmasq.conf-bak
echo 'conf-file=/home/vardenis/.dnsmasqrc' > /etc/dnsmasq.conf

Dabar is paprasto user (ne root) galime keisti dnsmasq konfiguracija /home/vardenis/.dnsmasqrc. Tame faile rasom:

interface=eth0
listen-address=127.0.0.1
resolv-file=/etc/resolv.dnsmasq.conf

Blokavimas reklamu paprastas, rasome i faila /home/vardenis/.dnsmasqrc:

address=/plus.google.com/127.0.0.1
address=/twitter.com/127.0.0.1
address=/yandex.ru/127.0.0.1

Sukuriam nauja faila /etc/resolv.dnsmasq.conf ir jame surasom googles dns serverius (nera butina googles aisku, galima naudoti ir tai ka grazina dhcp):

echo 'nameserver 8.8.8.8\nnameserver 8.8.4.4\n' > /etc/resolv.dnsmasq.conf

Toliau sukurkim faila /etc/resolv.conf.head, jis bus naudojamas kas karta generuojant /etc/resolv.conf faila.

echo 'nameserver 127.0.0.1' > /etc/resolv.conf.head

Dabar liko start/restart dnsmasq servisa

/etc/init.d/dnsmasq restart

Patikrinam ar veikia, ir ant kiek veikia geriau:

dig @8.8.8.8 google.lt | grep 'Query time'

;; Query time: 36 msec

dig google.lt | grep 'Query time'

;; Query time: 0 msec

Kaip matom dabar dns uzklausa uztruko 0 msec, kas yra tikrai puiku. Daugelis "moderniu" tinklapiu naudojasi soc tinklais, ir jie baisiai apkrauna musu narsykles, uzblokavus tokius tinklus tikrai pagreitina firefox'a ar chroma. Patikrinti ar veikia blokavimas galima su komanda:

dig +short twitter.com

127.0.0.1

Jeigu taip ir yra, tai valio!
