89 % zranitelností IT infrastruktury v českých školách je kritických

včera 13:22 | Zajímavý článek

České základní a střední školy čelí alarmujícímu stavu kybernetické bezpečnosti. Až 89 % identifikovaných zranitelností v IT infrastruktuře vzdělávacích institucí dosahuje kritické úrovně, což znamená, že útočníci mohou vzdáleně převzít kontrolu nad klíčovými systémy. Školy navíc často provozují zastaralé technologie, i roky nechávají zařízení bez potřebných aktualizací softwaru a používají k nim pouze výchozí, všeobecně známá

ovpn spojenie

Přečteno: 1295×

Odpovědět | Admin

Snazim sa rozbehnut ovpn, ale mam s tym dost problem. Postupoval som podla toho navodu. Urobil som nejake zmeny, napr. DNS servery som pouzil google

push "dhcp-option DNS 8.8.8.8"
push "dhcp-option DNS 8.8.4.4"

Dalej som vynechal komplet nastavenie Packet Forwarding, pretoze som to pochopil tak, ze vpn klienti maju skrz vpn pristup do inetu (a toto ja nemam v umysle (chcem aby klienti mohli len na server a dalej uz nie)). Dalej som needitoval tiez

/etc/ufw/before.rules

Cez generovanie certifikatov a klucov som sa dostal az na koniec a spustil som sluzbu, ktora bez problemov funguje.

tun0      Link encap:UNSPEC  HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00  
          inet addr:10.8.0.1  P-t-P:10.8.0.2  Mask:255.255.255.255
          UP POINTOPOINT RUNNING NOARP MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:100 
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

Problem mam pripojit sa ci uz z linuxu, alebo win na server.
Skusal som to z win_xp pomocou win openvpn klienta.
U klienta su potrebne tieto subory

client1.crt
client1.key
client.ovpn
ca.crt

a hlavne spravne nakonfigurovany

client.ovpn

Podla how to ma client.ovpn obsahovat aspon toto:

remote 192.168.1.2 1194
ca ca.crt 
cert client.crt 
key client.key 
#pouzil som relativne cesty, kedze subory su spolu s client.ovpn v jednom adresary

a to je hadam aj vsetko. V konfiguracnom subore je toho ale trocha viac. Nejake example som nasiel a trocha som si ich upravil

dev tun
proto udp-client
remote 192.168.1.2 1194
ca ca.crt
cert client01.crt #tak isto ako aj na servery
key client01.key #tak isto ako aj na servery
tls-client
port 1194
ping 15
ping-restart 45
ping-timer-rem
persist-tun
persist-key
mute-replay-warnings
verb 6
cipher AES-256-CBC
auth SHA1
pull
auth-user-pass login
dhcp-option DNS 8.8.8.8
route 192.168.1.0 255.255.255.0 10.8.0.1
redirect-gateway

Nechce sa pripojit ani s tymto nastavenim. Uz si nespominam co bolo v logu, ale ak sa to dlhsie nepripajalo, tak tam drblo nejaku blbu adresu 169.x.x.x (nie 10.8.0.x ako by malo).
Zatial to testujem len v LAN (vid obrazok a chcem sa pripojit jednym z PC (ktory je v switchi) na 10.8.0.1 (na obr je zle ( 10.0.0.1)).
Ak by toto fungovalo, chcel by som to skusit na wan.
Vyzera to ale na porod :)
Ak je potrebny log, tak ho sem mozem zajtra copnut (dnes uz fakt nevladzem :) )

upozornujem, ze v linuxe som vecny zaciatocnik ...

Nemusel si zakladat nove vlakno, ale nevadi.. Na Mikrotiku potrebujes pronatovat UDP 1194 na 192.168.1.2 z te verejne:

/ip firewall nat add chain=dstnat dst-address=69.69.69.69 protocol=udp dst-port=1194 \
    action=dst-nat to-addresses=192.168.1.2 to-ports=1194

Ktera zaroven patri do konfigurace klenta:

remote 90.60.90.60 1194

Mimochodem, kdyz uz mas ten Mikrotik mohl jsi VPN sestavit uz na nem, cela tahle sarada je uplne zbytecna..

Rozbalit Rozbalit vše Re: ovpn spojenie

Nove vlakno som zalozil, preto, lebo uz sa to nehodilo k titulku (tap, alebo tun). V tomto by som chcel vlastne trocha rozobrat pochopenie a detaily OVPN.
Vlastne som aj trochu rad, ze si nacal mikrotik, pretoze ja som si najprv postavil ovpn na mikrotiku podla tohto navodu a znova som spojenie skusal, ale len v ramci LAN a v ramci LAN to funguje. Do WAN som to zatial neskusal, ale uz som si kupil 3G modem a mozem spojenie testovat.
Je mi to vlastne jedno ci bude OVPN na mikrotiku, alebo na linuxe x86, dolezite je, aby spravne fungovalo (podla mojich poziadaviek) a bolo dobre zabezpecene.
Spojenie niekedy nefunguje a clovek (laik) nema ponatie preco. Nepozna principy, nepozna nastroje ako to odsledovat a niekedy uplne staci jemne pozmenit urcitu direktivu v konfiguraku a odrazu vsetko funguje.
Siete, linux a celkovo vypoctova technika nie je mojou pracou, ale cisto len konickom (nestudoval som to). Aj ked na internete je spusta kvalitnych materialov pre studium i ked bohuzial na nestastie vacsinou su v anglickom jazyku (nie vzdy to dokazem spravne pochopit).
Vratme sa k tomu OVPN, preco sa klient nechce spojit so serverom. Zrejme podla toho navodu v client.ovpn nestacia 4 riadky s remote, ca,cert a key, ale je potrebne ho o nieco doplnit, napr. ze sa jedna o klienta, urcit protokol a pod...
Aj ked som pouzil akysi example, ktory som si upravil aby to bolo v sulade s konfigurakom na servery, tak ani vtedy sa to nepripojilo. Skusim tu este dat konfiguraky servera a klienta, ci niekto nenajde nejaku chybu.
thx

Doporucuji ceskou knihu TCP/IP & DNS(Dostalek, Kabelova). Tam se napriklad dozvis, ze nektere "privatni" IP adresy nejsou smerovane v "internetu" a dalsi..

Kniha je volne dostupna aj tu, tak som si ju stiahol, ale nemyslim si, ze po precitani budem guru. Chce to hodne trenovat a robit prakticke skusky/pokusy (teoria je sice dobra, ale prax je dolezitejsia). Poznam teoretikoch, ktori toho narozpravaju, ale maju problem prakticky urobit jednoduche veci.

Pozri sa sem, ja uz som v takom stadiu, ze to robim skoro pokus/omyl a ked tu routu zakomntujem, tak sa u klienta nevytvori ani tun. Ked by si pozrel na schemu siete na ktorej to skusam, tak vlastne tie PC su prepojene len switchom (su v LAN v jednom subnete).

lokalne to nahodit musi jit, jestli to ma byt server pro roadwarriory, melo by byt v serveru jeste mode server, bez toho se nastavuje VPN 1:1.

muj configuk pro TUN vypada takhle:

mode server
dev tun0
tls-server
port 1194
keepaliave 15 150
proto udp

ca ca.crt
cert server.crt
key server.key
dh dh2048.pem
persist-tun
persist-key
comp-lzo

teda neprepsal jsem vsechno, vynechal jsem nektere bezpecnostni veci, logovani, a hlavne routovani a redirect-gw ktere na lokalni zkouseni mit nemusis ale melo by to byt funkcni, posli sem kdyztak i log ze serveru ne jenom z klieta a prosim v konfiguraku neposilej zakomentovane řadky, akorat to komplikuje čtení a pochopení

Ping funguje na oboch stranach.
Mohol by som sa teda pustit do testovania na wan. Ak tomu spravne rozumiem, tak zmeny robim v configu u klienta a to take, ze zmenim

remote 192.168.1.2 1194

remote host_alebo_verejna_ip_servera 1194

Musim tam teraz pridat este aj routu ?
Na OVPN servery nemusim menit nic, ale este ako poznamenal NN, tak na routery by som mal prenatovat na stroj kde je OVPN server

/ip firewall nat add chain=dstnat dst-address=60.90.60.90 protocol=udp dst-port=1194 \
    action=dst-nat to-addresses=192.168.1.2 to-ports=1194

Malo by to teraz fungovat ? Pytam sa preto, lebo, skusat to mozem az v sobotu

routu pridavat nemusis, pokud ti staci dostat se na VPN server, pokud potrebujes dal, musis to uz naroutovat.

ano, pokud to ma fungovat zvenci, musist ten port dostat z gw na vpn server. Jestli je ten zapis vporadku nevim, ja to nepouzivam, delam to v iptables.
