Hey Y'all, I just set up a new old machine on my network. I did a net install of CentOS 6.7 on it replacing an outdated copy of Win XP. Of course I'm now in the throws of configuring the machine to be a useful member of society.

Hello! Attempt to scan a network with any method except plain ping results in an error: truss nmap -sT -p 21 '172.19.17.*' [...] sendto(0x4,0x8094200,0,0x0,{ AF_INET 172.19.17.0:0 },0x10) ERR#49 'Can't assign requested address' [...] What's strange that man on send(2) doesn't state that EADDRNOTAVAIL can ever be returned from sendto(). Quick look at nmap's site

I have a CentOS 4.2 machine. lokkit shows that a firewall is enabled, and it is customized to allow SSH, Web, and DNS traffic only. But if I run nmap against the server IP (from my home machine, outside the local network) it shows over 1000 open ports. Am I not understanding nmap, or is there something seriously wrong here? Here is a small snip of the nmap output (I can include it all if

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 As you all may know Fyodor of nmap fame has terminated SCO's rights to distribute namp with its products. See: http://www.smh.com.au/articles/2004/02/27/1077676955381.html I know this is off-topic, but I am interested in opinions on the subject of SCO using Samba in it's products while they declare the GPL is unconstitutional and invalid.

Dear all! Last evening I've noticed that my 5.2 box had strange result about nmap search. One port is randomly open when I look from user account. From root everything looks as expected. The comp is most time out of internet. The last thing was adding "expect" package. I am not paniced, could be hiting... Or something in "expect" package... It is random port from 53000 to

I guess this is an FYI Running NMAP (protocol detection, common ports) against my UIP200's causes them to reboot. firmware BS4.56. Be careful where you point that thing. -Nate

All, I've put a new asterisk server at another location and can't seem to get it working. What's the best strategy to debug connections? I'm doing inbound SIP only and have installed the server in the same way as I did on my DEV server. Running an nmap on localhost shows the port listening: ---------- [asterisk]/> nmap -sU localhost Starting Nmap 4.11 (

Ok, I''ve completely reinstalled Xen and I am still encountering the most curious problem. I set up a virtual network of eight domains: three are on a virtual DMZ network (10.0.1.0/24), four are on a virtual internal network (10.0.2.0/24), and a router connects the two. All the domains can ping each other and traceroute-ing between them shows the proper network structure (first hop:

Hi: I have a machine with four interfaces connecting four different networks. I am learning to use nmap and trying to force the nmap working only one interface. As nmap man page states, I use -e option and it would not work: nmap -e fx0 -v -sP 192.168.128.0/23 Starting Nmap 3.95 ( http://www.insecure.org/nmap/ ) at 2006-02-04 14:04 CST getinterfaces: Failed to open ethernet interface (el0)

I have been trying to set up printer sharing on the LAN.All machines are CentOS 5.2 fully updated. The problem server is a fresh build. The box it is replacing worked fine for many months. The problem appears to be a closed port 631 on the new box. iptables and ip6tables are stopped as shown by the output below. To confirm I was using nmap correctly I ran it against the old server first which

Hi all! I'm a bit curious about this I found out while running nmap scans on some of our machines. It seems that OpenSSH 3.0.1p1 and 3.0.2p1 doesn't like the nmap scan. I have put the logging to debug and run "nmap -p 1- <machine>" and it resulted in the below: error: accept: Software caused connection abort Our servers are Solaris 2.6 and Solaris 8 machines with
