Also ssh'ing to an external box and using the last command should also have the same effect.<br>The accesses to port 26390 are probably a script testing you ip for a known exploit (probably expecing a windows box) and you should not worry about it if the request count is low. Also DoS does mean Denial of Service.
<br><br>What you might want to try as an experimant is, if you router has a DMZ option then you can try giving you linux box the external IP, this will allow you to verify whether it's you router or your ISP that is blocking the inbound connection.
<br><br>Hope this helps.<br><br>--N<br><br><div><span class="gmail_quote">On 18/01/07, <b class="gmail_sendername">walt</b> <<a href="mailto:walt@helvatron.co.uk">walt@helvatron.co.uk</a>> wrote:</span><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

Steve/Neel/anyone else who want to comment,<br><br>Thanks for your

don't have any problems <br>inside my little network. i can browse

box. when i go to<br><a href="http://www.whatisimyip.net" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">www.whatisimyip.net</a> i get a totally

possible? i restarted my router and the it <br>gets a new IP but
the whatismyip is still different.<br><br>i have the router set up to forward
any tcp for port 3000 onto the<br>particular box. i also have the remote
management switched on - its just<br>one of those consumer netgear
things. that should allow me to access <br>remotely the router set
up. it's set up for port 8080.<br><br>ok, so when i go to access the router
from the internet onthat port i<br>get nothing. however i tried out
neels suggesion and used nmap. that<br>told me ports 80 and 5190 are open. it
says 3000 and 8080 are closed. <br>my router is set up that 3000 and 8080
should be open????? also, 80 and<br>5190 closed??? what is going
on? for nmap i used the IP address the<br>router tells me it
has.<br><br>the router has a log, all that is showing is that i constantly get
<br>attempts made on port 26390? (Dos) whatever that
means? does that mean<br>denial of service? quick though came to
me...does that prevent access<br>from outside? is that my
problem?<br><br>any help appreciated? this problem is more than a

Guys,<br>>
Can any one help me out with this silly
problem?<br>><br>>
I have a spare box set up for learning ruby on rails,
<br>>
and i want to
view<br>>
pages on it from the internet (eg work). however
my<br>>
router simply
WILL<br>>
NOT behave as though it is visible ofn the internet.
<br>>
i cannot ping
it<br>>
or anything. in the past i had ftp and mysql
going<br>>
through it from
the<br>>
itnernet onto my little network to a particular box,
<br>>
but now it
just<br>>
won't play ball. i checked and double checked i
have<br>>
the right ip
and<br>>
i'm sure i have it correctly. any ideas? i enabled
<br>>
port forwarding
for<br>>
3000 which is what ruby on rails and webrick uses
for<br>>
development.
but<br>>
ithink its nothing to do with the box becuase there is
<br>>
no record in
the<br>>
router log of any connections being
attemped????<br>><br>>
does anyone have any suggestions? is it possible
the<br>>
isp blocked it
<br>>
somehow?<br>><br>>
cheers,<br>>
