I've installed the 3.2 server on a FreeBSD box and it appears to be working correctly. However, I've installed the NessusClient v3.2 on an XP SP2 box and am running into a problem. Specifically, I can connect to the Nessus Server and create a simple scan against say, one host/Microsoft Patches but the scan never finishes (as in 8 hours later). A PS shows the "nessusd: testing boxa (nessusd) and no error messages.
I have witnessed the same thing on my side. I am running also a Nessus Client 3.2.0 on Windows XP SP2 (fully patched, English version) and Nessus 3.2.0 on FreeBSD 6.3-RELEASE (without and with patches applied through freebsd-update). Here are some details that might interest you wrt further tests I've conducted when I noticed this: --- - I use the default scan policy. - I request a scan of 10 _live_ targets (a mixture of Unix/Linux and Windows boxen). Before each test described below, I confirmed that the targets were alive using ICMP. During each test described below, I ran an nmap scan which successfully completed on each of the targets. - There is no filtering device such as a firewall/IPS/etc. involved. - When I use a Nessus Client 3.2.0 on Windows XP and nessusd 3.2.0 on FreeBSD 6.3-RELEASE, I see on the server side a process for each selected target. I don't see anything on the left-side of the GUI. I let the scan run for 24 hours with no displayed results on the GUI. Then I decided to tcpdump on the server side only to see that from time to time (not measured precisely but seemed to me very long), a packet is sent towards one of the targets. When I click on Stop on the GUI, I get a message which I don't recall precisely but which basically says that I was disconnected by the server. The nessusd scanning processes still shows up on the server side and only way to get rid of them is a SIGKILL. Should have strace'ed them maybe beforehand? - When I use a nessus CLI client and a nessusd 3.2.0 on FreeBSD 6.3- RELEASE, I have the same results as above. tcpdump about 30 minutes after starting the scan shows also the same behavior. - When I use a Nessus Client 3.2.0 on Windows XP and the server is also on the same machine, Only two targets shows up and are fully scanned. I repeated the operation twice and during the two following runs, 2 targets were scanned again (not the ones that were scanned during the first scan) then 1 target (neither from the first or the second scan). - When I use a Nessus Client 3.2.0 on Mac OS X 10.5.2 and the server on the same machine, all ten targets shows up in the GUI and are scanned. --- HTH to diagnose the problem if any. -- Saad Kadhi -- saad@docisland.org "True security is born from love alone" -- Antibalas _______________________________________________ Nessus mailing list Nessus@list.nessus.org http://mail.nessus.org/mailman/listinfo/nessus
