Does Nessus scan a host for more than 6 hours normal?

[Ruiyuan Jiang]

Hi, I connected my laptop to a DSL line and tried to scan one of my hosts in
overseas. I started to scan at 10:36 AM EST time. Up to now my laptop is
still scanning the host (4:30 PM EST). On the scanning screen, I saw
portscan bar is at 100% around 1 PM EST and now it is still at the same
location (100%) 3 and half hours later. On the remote host that is being
scanned, I saw my laptop is doing portscanning which is what I want. I saw
the same port is being scanned more than once. I don't know why? I don't
know how long it needs to finish the job.

On the nessus setup screen, I did "SYN scan" and "User specified range" for
"Port range" and I define the range from port 1-60000. I disabled the ping
and tcp ping. 

On my laptop, I did "uptime" and "top" and I don't see that the load is
high. I did "ps -ef | grep nessus" and I saw "nessus -D" is listening. I
also saw that nessusd does "test" with the plugins "synscan.nasl".

Is it normal to take more than 6 hours? Thanks in advance.

Ryan
