carloss Posted March 30, 2010 Share Posted March 30, 2010 I just started an (ze)nmap scan on my vServer. On it is a teamspeak 3 Server, apache, ftp, postfix, mysql, ISPconfig etc Running. Problem is the Server whent down while i did the scan. I started an "Intense Scan" and later a "quick scan plus" nmap -T4 -A -v -PE -PS22,25,80 -PA21,23,80,3389 IP and nmap -sV -T4 -O -F --version-light IP WHile I did the scans the webinterface, teamspeak ...everything....did not respond anymore! And nmap crashed both times. So an nmap scan on my server is a denial of service! o_O Why is that so? What can I do against it? I installed everything except of the teamspeak Server two days ago... Sorry for my bad English Im from the "Jasager" Country XD Quote Link to comment Share on other sites More sharing options...
Sparda Posted March 31, 2010 Share Posted March 31, 2010 Where is your server hosted (as in connection speed etc.)? What OS is it running? Also, I suspect it might be your computer that is DOS'ed by nmap performing the scan, which would explain why nmap crashes. You should try this again but instead of trying to access the server from the computer that is running nmap use a different computer.

operat0r_001 Posted March 31, 2010 Share Posted March 31, 2010 nmap can be a very dangerous tool .... just connect port scanning can bring embedded and other shitcan devices down for the count .. and even create permanent problems ...
