neocytrix Posted May 2, 2004 Report Share Posted May 2, 2004 Hello everyone, I have been having a wierd problem, im not sure if its my portscanner(s) or my internet settings. I have tested both nmap and portscan and both are having problems scanning, when I use nmap to scan my friend's IP (he isn't using a firewall or anything like that) nmap comes up with the following error: Note: Host seems down. If it is really up, but blocking our ping probes, try -P0 Nmap run completed -- 1 IP address (0 hosts up) scanned in 12.062 seconds The other program portscan doesn't scan it at all. however, im not sure if the problem is the portscanners because I can't ping his IP either and I am able to ping 127.0.0.1 with both of them just fine. I don't have any idea what to do, anything helps. -neocytrix Quote Link to comment Share on other sites More sharing options...
brancalessio Posted May 2, 2004 Report Share Posted May 2, 2004 Did you try nmap -P0 Quote Link to comment Share on other sites More sharing options...
neocytrix Posted May 2, 2004 Author Report Share Posted May 2, 2004 Yeah that doesn't work either, I haven't successfully done it to any IP except 127.0.0.1. -neocytrix Quote Link to comment Share on other sites More sharing options...
jlc Posted May 4, 2004 Report Share Posted May 4, 2004 If you can't even ping his ip, you have something else going on. Do you have a firewall up? It's possible the isp is blocking icmp request such as ping? What's his Ip & yours, i can't do it from work, but I could do it when i get home l8r. That will help determine if it is more than just you or him. of course maybe you don't want to give that up, but that is up to you. Quote Link to comment Share on other sites More sharing options...
neocytrix Posted May 4, 2004 Author Report Share Posted May 4, 2004 We are both on broadband lines so our IP doesn't change, im going to PM you the IP's instead of put them out so the public can't see them. -neocytrix Quote Link to comment Share on other sites More sharing options...

neocytrix Posted May 5, 2004 Author Report Share Posted May 5, 2004 Okay new info, I can ping www.google.com without a problem and I can log onto one of my friends SSH server, but my friend can't ping me and I can't ping him, that goes for another friend that uses Windows to. -neocytrix Quote Link to comment Share on other sites More sharing options...
jlc Posted May 5, 2004 Report Share Posted May 5, 2004 (edited) I've got a few things to come back, not much. Are you running any kind of firewall? Um, portsentry, anything like that? Your friends Starting nmap 3.50 ( http://www.insecure.org/nmap/ ) at 2004-05-04 20:49 CDT Interesting ports on DELETED TO HIDE THE IDENTITY. ;-) (The 1657 ports scanned but not shown below are in state: filtered) PORT STATE SERVICE 1025/tcp open NFS-or-IIS 3531/tcp open peerenabler Nmap run completed -- 1 IP address (1 host up) scanned in 230.968 seconds looks like his is running Windows with some p2p software running?? edit: took ip away Edited May 5, 2004 by cybrjackle Quote Link to comment Share on other sites More sharing options...
jlc Posted May 5, 2004 Report Share Posted May 5, 2004 Another thing to do is install NESSUS and run it against yourself and see what comes back. Quote Link to comment Share on other sites More sharing options...
neocytrix Posted May 5, 2004 Author Report Share Posted May 5, 2004 Im having quite a few problems with installing stuff, ect. Im going to re-install mandrake this weekend, thanks for your help, this should solve the problem because the problem is only recent and it started off fine. Thanks for taking the time to test that for me and everything, its greatly appreciated. -Neocytrix :D Quote Link to comment Share on other sites More sharing options...
