[ale] new Box crashes when nmapped

Fri Aug 19 08:22:44 EDT 2005

I tried your command line option and it did not find any host on my network. But when you change the -PT to -sT, it will find the host. Give that a try.

Aha! I had gtk2-devel installed but I needed gtk+-devel installed as 
well. Subtle but very important.

Thanks.

Has anyone heard of problems with NTP flooding a server? I received a
call from the USNO stating that my system was flooding them with NTP
requests at a rate of over 70 per second. I shut ntp down for the time
being until I can figure out the cause.

I'm running 4.1.2 on Fedora. No updates available from RH.

Thanks,
- Chuck

But the string " XMI001" *is* an instance of "XMI001" preceded by
zero non-space characters (and those zero non-spaces are preceded
by some spaces), so would match both of your expressions.

This definitely requires negative lookbehind, or else a multi-step
filter (get the lines containing "XMI001", then discard the ones
containing " XMI001"). "grep XMI001 [file] | grep -v ' XMI001'"
should do it. Except I think Chris said that the input is NOT
line-oriented, which means that no line-oriented filter is going
to be able to do the right thing.

I've got a new RH ES 3 box setup (pretty much default settings) and when
I nmap it from a second host it freezes and needs to be cold booted.

Here's what I am doing:

nmap -PT -p 1- 192.168.3.6

I can't imagine that this is normal or expected behavior. Any ideas on
what could be happening?

Tia,

One thing that I have heard second hand it that if you buy
a box such as the Linksys to use with Vontage and later
decide to cancel, you either have to return the box to 
Vontage or pay a $50 fee.

Just something to be aware of!

John, I think Vonage uses standard VOIP phones. If so, they just use 
the SIP protocol ports (5566, etc I think). I just recently set up an IP 
phone here at home from my office. They're pretty slick devices.

You don't need to forward DNS to the ATA. I think they suggest that to 
make sure that DNS is available to the ATA. Only ports that need to 
forwarded from the outside of your network to the ATA is UDP 5060 and 5061.
