According to nmap documentation, you can test for a stateful packet inspection firewall by using the following command.  In my example, I’m testing port 443 (https) as I know that it is an open port.  -Pn tells nmap to NOT run the ping test, and -sA tells nmap to send an ACK packet.

# nmap -Pn -sA -p 443 #.#.#.#

nmap discussions I’ve read state that an “unfiltered” response indicates a stateless firewall, and a “filtered” response indicates a stateful firewall.  Unfortunately, nmap lists my firewall’s response as “unfiltered” or stateless.  This leads me to believe that the NSA 240 is NOT an stateful firewall.

PORT    STATE      SERVICE
443/tcp unfiltered https

If I do a tcpdump on the source system that is running nmap, I’ll see that an ACK is sent, and that an RST is returned from the target system.  All this leads me to believe that the NSA 240 is stateless, and is allowing the RST’s to come back from the target system.

However, if I do a tcpdump of port 443 on the target system, I see absolutely NO packets from the source system.

I believe that the SonicWall NSA 240 is responding with the RST packet without actually forwarding the ACK packet to the target system.

So I’m sitting here wondering if nmap can accurately tell whether a system is stateful or stateless? Just because an RST packet is returned, doesn’t necessarily mean it is coming from the target system.

Conclusion : I’m going to log a ticket with SonicWall to clarify this issue for me.  And for now, I’m going to use the empty tcpdump log from the target system to verify that the NSA 240 is stateful. This should allow us to pass the PCI 1.3.6 check. But I still want an answer from SonicWall as to why it is responding with an RST packet.

And the developers website is missing the DNS entry, so it’s not coming up.

For now, I’ve uploaded my latest copy of the “wp-recaptha” plugin from one of my sites.  Though I’m hesitant about continuing to use it until I know why it has disappeared.  Any information is welcome.

Unfortunately, Yahoo just responds by redisplaying the “reply” form and doesn’t accept my response.  I am therefore posting this information on my blog to try and see if others are having this same problem.

Basically, as the poster above states, I’ve been using this service for as long as I can remember.  And suddenly, last night (20-Sep-2011) the service stopped working.  I’m sure there is some news somewhere about Yahoo not supporting this service, but searching google for the 403 error does not produce any useful results.

I took the quick/easy way out.  I switched over to using the Google geo-coding service documented at the following address.

Perhaps someone can shed light on why the Yahoo service has stopped working?  I’m suspecting it could be because I was accessing it from an Internet/IntRAnet site that is not publicly visible.  But what do I know?  ;-)

Basically I was cheap and didn’t get a DVD drive with my server from Dell. I kind of regretted it, but at least I learned something new here.

I used this process on a Windows Vista 32bit system to create the 64bit install disk. And it worked superbly.

The code above was a direct copy taken from the link below on Andrew Brampton’s website.

Only difference is that I had to run “clean” twice for some reason, and also chose the file type of NTFS instead of FAT32.

Invariably, when someone on a mailman list complains of spam through their ISP and I receive a message back from the feedback loop, they (Comcast, AOL, etc.) strip out the complainers email address, making it impossible to trace and fix the problem.

To address this problem, the email address can be included in the footer of each message in the form of an encoded URL string where the AT (@) sign is replace with it’s hex code of %40. The feedback loops don’t recognize this syntax and consequently do not strip the encoded email address, allowing me to remove the complainers from the mailman list, or investigate further.

By default, cPanel and mailman do not allow the customers to include this encoded signature, so the following must be done.

Edit the file located at
/usr/local/cpanel/3rdparty/mailman/Mailman/mm_cfg.py
And make sure the following is at the bottom of the file.

Once this is done, the customer can go into their mailman settings, and place the following code into the signature of each message for the list.

Unsubscribe: %(user_optionsurl)s

This will include the encoded email address in the string. Credit to the following cpanel thread that allowed me to address this problem.

?Ultimately it was this thread?here?that solved the problem for me.

Execute the commands below.

After searching the Internet for over an hour trying to locate either 1) instructions for resetting the bios password on the emachine t1090, or 2) a user manual for the emachine t1090, I discovered the solution to my problem printed inside the case of the system.

See this picture of the sticker below that clearly shows instructions for clearing the bios password.

In the next image, you can see how I took jumper 8 (j8) and moved it over to pins 2 & 3. ? Once I rebooted the system with these new jumper settings, I simply moved the jumper back to pings 1 & 2 so that the password could be set again in the future if necessary.

Hope this information is useful to someone that has lost their BIOS password on this old emachine. Now, if your emachine is making sick sounding/groaning sounds during the reinstall like mine is, I can’t help you there.?

A google search will reveal many results for why this happens. Here is the simple solution I used to fix this problem for me.

I logged into the old VMware Server system as root. Yes, this solution requiress that you have both a VMware server AND the target ESXi host up and running. Also, the vmdk file must be uploaded to the ESXi host.

From VMware Server, issued the following command. Be sure to replace “source” and “target” with the names of your files, and “datastore1″ with the name of your datastore.

Then you can use the new “target.vmdk” file to boot on your ESXi host.

Whatever the case may be, there is a solution.
