Rb 750G danas sam ga nakacio, evo sada gledam na 150 aktivnih pppoe konekcija i manje od 10mbita protoka, procesor skace na 90%,uglavnom je na oko 70-75.

Jel to normalno??

Meni samo nije jasno, cime je to RB750 zasluzio posebnu temu? Jeste jeftin ali je jedan od najslabijih RB-ova i koliko vidim neki pokusavaju da rade kompletan internet provajding preko njega. Prosto ne ide, koncipiran je kao jeftin SOHO uredjaj, koji ne moze bas sve.

Ne, ne, ono, slobodno ti pitaj, ono... Tema ovog foruma je "MikroTik RB 750 - iskustva", ja sam je postavio sa ciljem da se iznesu iskustva sa ovim routerboard-om u odnosu na druge MikroTik platforme, a ne da se razglaba o osnovama rutiranja. Ovo o čemu vi pričate nema veze sa temom...

Bolje pročitaj lepljive teme na vrhu, npr.

• Uputstvo o osnovnim podešavanjima, deljenju interneta i kontroli protoka korisnicima
• Instalacija mikrotika kao rutera

Da pitam da li se i ostalima desava kada ostave remote pristup svakodnevno flood-ovanje logina, posebno preko SSH?

Sta je to sto momentalno nacini MT vidljivim, da ga neko u roku od pola sata 'nadje'? Drugi ruter nema ovih problema, ili ima vrlo retko kada bas neko nmap-uje ceo IP opseg...

Zanimljivo da skoro nikada ne pokusavaju (tj. skripta) sa admin koji je default username :)

Tacno tako, verovatno braca kinezi i azijati rokaju skriptom cele IP opsege putem dictionary based napada pa gde prodje - prodje, a fingerprint MT-a je Linux-based pa zato gadjaju... dok npr. kada dignem obican modem-ruter nema teorije da se pojavi bilo sta u logu barem nedelju dana (doduse nema SSH vec samo Telnet/web), ili ako neko bas slucajno nabode IP.

pa valjda kad kreira admin-a kao usera, pusti ga samo sa lokalnog opsega. onda kreira jos jednog usera, setuje mu privilegije na read only, i njega pusti s vana. bolje je rjesenje mozda dignuti vpn server (nabaciti javni ip na neki dinamicki dns), kaciti se preko vpn-a i onda iz lokala pristupati tiku. to je po meni najbolja zastita.

Vulnerability: SSH Protocol Version 1 Supported
Port : 22
Threat:
SSH1 protocol was deprecated due to multiple vulnerabilities and design flaws.
Among multiple vulnerabilities that exist in SSH protocol Version 1 are:

* a CRC32 compensation attack detector vulnerability (buffer overflow)
* an unauthorized session key recovery problem

Multiple vendors' implementations are vulnerable due to the fact that these are protocol design errors. Version 2 of the SSH protocol fixed these errors.

Solution:
Disable SSH1 support. See your vendor's Web site for information on how to disable SSH protocol Version 1 support.

Nemam iskustva sa ovim uredjajem i taman kada sam resio da kupim slican - Cisco RV042, naisao sam na ovu temu. U koliko bi mogao da mi zavrsi posao, MT bi me kostao 3 puta manje od ciska. Pitao bih nesto, neke iskusnije, ali ne znam kako ce BigFoot da protumaci i da me stavi u red sa onima koji samo nesto pitaju.
Naime potreban mi je za slicnu svrhu kao za net balansing, znaci u njega ulazi internet od 2 provajdera s tim da od jednog dobijam adresu od dhcp a u opsegu 192.168.5.2 do 255 i sluzio bi mi samo da pridjem preko tog rutera drugom internetu i resim eventualni problem sa unutrasnje strane ( reset ili sl. ) na linku koji ima u nizu 3 rutera ubiquity prema drugom provajderu. Prema njima (ubiquiti ) mogu da pridjem spolja preko javne adrese, ali ponekad mi se javi problem da se zaglupi neki od njih i moraju da se rebutuju. Kako cesto nisam u kancelariji potrebno mi je da uvek mogu da pridjem uredjajima sa udaljenih lokacije tj van moje mreze.
Nadam se da nisam mnogo zapetljao, ako jesam nacrtacu. Pitanje je da li mogu i kako.

Osim što si izmenu posta poslao kao novi post, pa imamo dva, za šta mislim da je forum kriv, valjalo bi da kažeš o kojim protocima se radi koji će ići kroz taj ruter, kako će on raditi Load Balancing i na koji način mu želiš pristupiti, VPN, PPTP, L2TP, PPPoE, natovanjem nekog porta ka unutrašnjoj mreži i sl.? Ako nemaš puno obrade RB-750G će raditi, ali čim zahtevi malo porastu, hoće da zaglupi, zakuca na 100% i resetuje se posle nekog vremena.
