I have an HP EliteBook 8730w HP machine with XP SP3. The NIC is a 82567LM Gigabit. Wireshark Version 1.6.1 is seeing a flood (packet ea/.001068 seconds +/-) of protocol 0x8899 Ethernet II packets (All outgoing; no responses). Packet length ranges from 64 to about 1499 or 1518 packets long. The problem I have is that I cannot find the Source MAC on my (small home) network (I have tried several MAC scanners), nor do I know anything about the destination address.
Source: f8:c0:01:7c:65:cc
Destination: Dell_79:08:f2 (00:19:b9:79:08:f2)
Type: Unknown (0x8899), Ethernet II
Data (1504 bytes)
5 lines of data:
0010 88 64 11 00 14 ef 05 d6 00 21 45 40 05 d4 ac 25 .d.......!E@...%

.
.
So, I have no such source or destination MAC on my network (that I can tell) , am seeing an ongoing flood of data anytime day/night. To my knowledge, I have no Dell equipment on my network (two printers, 4-5 computers, a couple of Smart phones, and several Security DVRs). Most computers behind one or more switches. I am certain that I have no Realtek routers/switches or anything that might be using a managed protocol i.e. Realtek Remote Control Protocol (RRCP) Type 0x8899.

there's a problem with the personall billing web page.
I've tried Chrome, Firefox and IE and all three won't work. The problem is when I go to remove a billing method. It puts the Yes/No question text on top each other. As a result it's impossible to remove old charge cards.

It is really frustrating for someone to come into live and try to get an answer out of you in the 5 minutes, only to not want to pay for an answer... I usually suggest that people just put it in as a question.... Am I the only one aggravated with this? It seems like EE get's their $$ and I get nothing but headaches...

Have you read about a released feature you liked at Experts Exchange, or a bug that was fixed only to find it didn't work for you? That's happened to me and I've just stumbled on the reason why!
You need to log out of Experts Exchange and then log back in for the new features to show up, or bug fixes to take effect on your EE account. See below.
Once you do that, all new features and bug fixes come into effect.
Hope that's helpful

I think in this particular case you may have worked around something by logging out and back in. That doesn't mean that we intentionally fixed it. "You need to log out of Experts Exchange and then log back in for the new features to show up," this is definitely not the case for new features nor should it be required for bug fixes.
Once we have all the details on how to reproduce that problem, we will have a chance to intentionally fix it. :) However right now I think it may return after you happen across the steps again.

You're most likely correct Craig.. I got a little excited when something wouldn't work and then did so probably jumped the gun a bit :)
However right now I think it may return after you happen across the steps againAgreed.. Nailing those steps down can be a frustrating exercise though. It's like fighting with a poltergeist that only rears its head once in a while just to irritate you! lol..

Not sure if this really counts, because I wasn't the SysAdmin in this scenario; instead, I was the problematic user! But here goes: back when I was a student at CalPoly, we had access to the school's UNIX system for things like our email. I had taken the C and UNIX class, so I knew my way around the command line enough to do more than just use PINE to check my email. I also really liked the SETI @ Home project, so I got the UNIX version of the client and installed it on my account on the school's system and would just let it run.
I think maybe I had it going for a month and I have no idea what sort of resources it was taking up. I imagine it wasn't really all that bad, but eventually, a SysAdmin did shut it down and told me not to do that again...
I imagine college SysAdmins have to deal with a lot of shenanigans like that! :-D

Once a customer called me and told our software tells him 'Hardlock not found' - after 10 minutes verifying everything (driver, service, client) was installed fine and running, just for fun and coz I was a little bit frustrated, I aksed if he really plugged in the hardlock - the customer was a bit surprised and answered "No, it's here, laying in front of me, on my desktop - do I have to plug it somewhere?"
Another time I sent a PDF docu to a customer - he answered with a mail asking me what to do with this PDF. I wrote 'just open it to read or print it' - he answered he doesn't know what 'open' means and asked me if it would be possible that I open the PDF and send it to him 'opened'.
And one of my favorites, allthough it wasn't directly me: Once surprisingly I heard my colleague (usually a relaxed guy) yelling loud into the telephone "NO! STOP! Stop EVERYTHING! DON'T TOUCH the mouse! DON'T TOUCH ANYTHING! When I tell you 'click', click EXACTLY ONCE with the LEFT mouse button! WHEN I TELL YOU 'double click', click EXACTLY TWICE with the LEFT mouse button! As long as I don't tell you anything DON'T TOUCH ANYTHING!!!"

Experts Exchange is based in San Luis Obispo, otherwise known to locals as 'SLO'. The city of SLO lost a valued member of its community a few months ago.
Recently, the city's assemblyman voted for a bill to name a portion of its highway to this man. On to the California State Senate Rules Committee. I hope it passes there as well.

A look at what happened in the Verizon cloud breach.
Active today
I was able to do this easily last night by logging into my Verizon account online and going to settings to change the PIN. I didn't even have to call customer service.
Yesterday, cyber resilience startup, UpGuard, issued a report that as many as 14 million U.S. Verizon customers have fallen victim to a hack that stole their names, addresses, account details, and PINs. The startup claims to have first notified Verizon on June 13th of the hack, citing a "misconfigured cloud-based file repository" as the cause.
In reply, Verizon has stated that there has been no loss or theft of customer information and that only 6 million customers may be at risk due to an informational cloud storage move where a third-party employee made external access available. Latest reports urge Verizon customers to update their Verizon PINs in order to safeguard their accounts.
Stay tuned for more information on what happened in this attack and how to safeguard your accounts.

First of all let me say that the only language that I speak is English, but in answering questions here I often come across people whose English skills are not the best and I’d like to be able to communicate better with them, and the following describes what I’ve done on occasion.
