> nmap -v -O -o /root/escaneo_del_servodor 192.168.0.1 Starting nmap V. 2.54BETA22 ( www.insecure.org/nmap/ ) No tcp,udp, or ICMP scantype specified, assuming vanilla tcp connect() scan. Use -sP if you really don't want to portscan (and just want to see what hosts are up). Host server.financialinvestmentservices.net (192.168.0.1) appears to be up ... good. Initiating Connect() Scan against server.financialinvestmentservices.net (192.168.0.1) Adding TCP port 110 (state open). Adding TCP port 80 (state open). Adding TCP port 631 (state open). Adding TCP port 200 (state open). Adding TCP port 443 (state open). Adding TCP port 127 (state open). Adding TCP port 515 (state open). Adding TCP port 901 (state open). Adding TCP port 139 (state open). Adding TCP port 25 (state open). Adding TCP port 143 (state open). Adding TCP port 22 (state open). Adding TCP port 3306 (state open). Adding TCP port 3128 (state open). Adding TCP port 88 (state open). The Connect() Scan took 0 seconds to scan 1542 ports. For OSScan assuming that port 22 is open and port 1 is closed and neither are firewalled Insufficient responses for TCP sequencing (3), OS detection may be less accurate For OSScan assuming that port 22 is open and port 1 is closed and neither are firewalled Insufficient responses for TCP sequencing (3), OS detection may be less accurate For OSScan assuming that port 22 is open and port 1 is closed and neither are firewalled Insufficient responses for TCP sequencing (3), OS detection may be less accurate Interesting ports on server.financialinvestmentservices.net (192.168.0.1): (The 1527 ports scanned but not shown below are in state: closed) Port State Service 22/tcp open ssh 25/tcp open smtp 80/tcp open http 88/tcp open kerberos-sec 110/tcp open pop-3 127/tcp open locus-con 139/tcp open netbios-ssn 143/tcp open imap2 200/tcp open src 443/tcp open https 515/tcp open printer 631/tcp open cups 901/tcp open samba-swat 3128/tcp open squid-http 3306/tcp open mysql No exact OS matches for host (If you know what OS is running on it, see http://www.insecure.org/cgi-bin/nmap-submit.cgi).
