SSH checker

[mindark]

Program scris în C# care sorteaz? o lista de host-uri cu ssh rulat pe port 22, în servere ?i routere, în dependen?? de cît RAM posed?.

Hosturile într-un fi?ier aparte în format:

host:user:pass

Programul îl rulati prin cmd.

Îl modific s? ar?te ?ara, uptime, viteza de internet etc., dac? topicul cap?t? aten?ie.

Poftim link.

Iat? ?i sursa, dac? cuiva îi este interesant

tu ce faci postezi doar de dragul de a face posturi? sau esti somnambul si nu sti ce faci? pui semne asa aiurea la fiecare post

[BkDService]

Oooooo merci mult, il cautam de muuult. O sa il testez imediat...il compilez pe un root. Dar arata cumva si motd`u? Pune si tu sa dea comenzile lsproc, uname -a la verificari.

[d4rkm4nx99]

te rog fi mai explicit nu prea am inteles cum se foloseste poate un tutorial video ar fi super

C:\Users\dark\Desktop\ssh chk>sshch.exe

sshch <threads> <ips> <routers file> <servers file>

C:\Users\dark\Desktop\ssh chk>sshch.exe mai departe ? Multumesc.

Mie mi-l vede ca virus si chrome cand il descarc si bitdefender.

Va era greu sa faceti un check-in pe virus total: https://www.virustotal.com/ro/file/19b3437794a893e183373261a6e57f5fdc42cc90818ece0cee17cabfb26b4ec5/analysis/1373439479/

da o multime de erori la compilare... vreau sa il folosesc pe linux. ma poti ajuta?

Asta in cazul in care incercai sa il compilezi ca C++ si nu ca C#
