Problems with SRW224G4 switch and Bridged Network Cards

Hello,
We have recently installed a SRW224G4 switch and have discovered that when we plug our DELL PowerEdge 2900 server into the switch, the switch loses all network connectivity and all of the LED's on the switch start flashing.
The server works perfectly well plugged into another switch, but as soon as we introduce the SRW224G4 into the network, either with the server plugged into that switch or any other, the problem re-occurs.
The only way we found we could eliminate this issue was if we disabled the Bridged Network connection on the two network cards on the server. If we do that, everything is fine, except the network performance of the server has dropped significantly.
The server is plugged into the 1GB ports on the switch, although we tried it on the 100MB ports and received the same problems. The switch reports that the ports are running at full-duplex.
Has anyone noticed this behavior before, and more importantly been able to rectify it.
Thanks in advance for your assistance,
Paul

I had this problem as well with any Linksys 2024 or rackmountable switch.. The trick is, you need to use the network cards management software to "team" or bridged the 2 NIC's otherwise the switch detects a loop and the whole thing locks up. So lame... Windows built in bridge mode stinks dont use it. When you use the Intel management software or Dell or HP's NIc management software you have the option to actually choose "redundant mode" where you can pick a Nic to be the primary, or you can choose Load Balancing where you can essentially double your throughput by joining the 2 nics.
In Windows 2008 Server, you actually do this by going to the Properties on the NIC in Device Manger. the software controls are now built right into the driver. pretty neat. 2003 you can check Device Manager the same way but not sure if it's the same as 2008, you might need to run the actual NIC management app.
Hope this helps

Creative Zen Micro 6GB/Problems with Power Switch and Firmw

The power switch on my Zen Micro has died. I can't turn it on or off unless I 'jump start' it from a USB cable and leave it alone to go into idle shutdown. I've had this player just three weeks and this is happened and frankly I'm disgusted. But wait, my story get's worse:
So before sending it back to Creative I thought that I should at least exhaust every possible cure. First on my list? A Firmware upgrade to v2.22.05. I downloaded the program and set about installing the new firmware but halfway through the process it hung and I had to end it prematurely. Now what I had was a ZM that apparently had v2.22.05 but was not being recognised at all by my computer. Media Explorer wasn't picking up on it and neither was WMP although strangely when I connect the device it's there in the Device Manager...
So, check back with the website and it said to download an update for Mediasource and that should solve the problem. Downloaded the patch but then realised that I hadn't installed Mediasource on my computer (can't remember why I didn't though). Went back to the downloads page and downloaded Mediasource. Tried to install it but I can't. The reason? because my computer isn't detecting the ZM and I can't install it until it recognises that it's there.
As a last resort I thought that I would try to use 'Rescue Mode'. Seemed simple enough, remove the battery and hold down the power switch. Then put the battery back in and wait for the rescue screen to come up. Seems easy enough. Oh wait, I don't have a working power switch.
What I do have though, is a small piece of plastic and metal that I can't turn on, can't turn off, can't put any songs on, can't listen to, can't fix and can't be bothered with. I have a ?60 paperweight.
Anyone at all have any idea what I should do? I just want to put it all in a box and send it back to Amazon with a request for a full refund or a threat to take them to the Small Claims Court.

Although a failed power switch is not unknown, I only recall seeing two or three other cases of this. It's not common.
If WMP isn't working with the device having v2 firmware something is wrong. Unfortunately this can be difficult to fix, but take a look here in the Zen FAQ at Nomadness.net.
MediaSource won't detect the player if there's some issue e.g. WMP0 not detecting it. You can of course also try installing Zen Micro Media Explorer (Creative Zen Micro Media Explorer Web Update to be specific) which has MTP support.
Are you are presumably under guarantee, and as you bought from an Internet store, it's best to return it direct to Creative. Contact Creative Support to arrange this.

Problems with Installing iTunes and wireless network connection

Every time I attempt to install iTunes it completely kicks the internet off and an error comes up that the wireless network adapter to not connect or is not detected. My internet service is connected to a router which I receive wirelessly to my laptop. I do not understand why it is happening and to get the internet to work again I needed to do a system restore. Any ideas why this is happening. Also when iTunes was installed it came up correctly, it would just not connect to the net. I have had a previous version on my old laptop but since purchasing this new laptop I am having such difficulty. On another note, if this problem can be resolved, once iTunes is working is there a way to get the songs from my old computer onto the new? Thanks for the help in advance!

I just saw your post and I resolved this on mine for my wired connection. I'm willing to bet that the issue is the same for wireless. Here's what I found.
Issue:
During the installation, iTunes installs some network components related to mobile device support over ethernet(Apple Mobile Device Ethernet Service - netaapl.inf). At the same time, according the logs, the install process removed OEM18.inf. This almost exactly coincided with the time that I saw the network connection die (preceded it by a few seconds).
Basically, iTunes appears to be removing a required network component.
Resolution:
After installing iTunes and the network connection breaking, remove the network device from Device Manager and allow Windows to reinstall it automatically.
The following instructions are for Windows 7, but they are close enough to follow for other versions of Windows.
1. Click the Start button (Jewel in Vista and Win7).
2. Right-click Computer and click Manage in the menu that appears (type your password or click Yes if prompted).
3. On the left side of hte Computer Management window, click Device Manager.
4. Click the arrow (or plus sign) next to Network Adapters to expand that section.
5. Right-click your network adapter and click Uninstall in the menu that appears.
6. Click OK.
7. Reboot.
Windows should automatically detect and reinstall your network device on boot.

Problems with mail, messags, and social network accounts

Hi,
first of all, sorry for my bad English.
I would like to know if there is a maximum limit of accounts (email, social network, etc. etc.) that OS10 can handle.
On my Passport (OS10 Version 10.3.0.675) I have the following:
- 1 BBM
- 1 WhatsApp
- 1 Facebook
- 12 Mail
Now, when I try to insert another account (for example mail or Twitter), I recived the following error message:
"The maxximum accounts has been reached".
Is that right?
With the Z10 and the Q10, if I remember correctly, I did not have this problem.
I need to add more email accounts, someone can help me?
Thank you all.
I'M NOT LAZY,
I JUST DON'T GIVE NOTHING!

Let me see what I can find out and I'll get back to you when I know more! Thanks

WRV200 - Problems with VPN Client and Internal network access

I have a WRV200 router and want to access the internal (Private Network) connected on the inside. I have successfully conected to the router with the Linksys VPN Client, but it does not appear to allow access to the internal network.
How do I enable NAT Transversal or Passthru? I have already selected all of the PPTP, L2TP and IPSEC Pass Through.
Has anyone gotten this to work?

I have actually gotten this to work. Issues surround this include the ability to get to the VPN if the main DNS is down (it does not fail over to the next DNS in the list).
If you unselect all of the boxes in the firewall General configuration, you can connect, but if you need to have all of this unchecked, what's the sense of having it?
Anyway, you can use the DoS Prevention, this is not interfering.

Problem with R2 signalling and satelite network

Hi,
Is someone have experience with voice satelite networks and R2 signaling.
Regards

Have you selected R2-pulse.
R2-PulseR2 line signaling type ITU-U Supplement 7, typically used for systems that employ satellite links (where a Tone/A bit is pulsed).
try command -- proceed-to-send
ITU pulsed line signaling (S-7) ACKs the seizure with a proceed-to-send signal (150 ms pulse). A variant of this signaling over satellite links does not use this signal. If this is configured, the router does not ACK the seizure for incoming calls and does not expect ACK for outgoing calls. This affects pulsed line signaling calls only. Not supported on AS5800 yet.

Problem with changing Label in Bridge CS3 and CS6

Hi there,
I am having some problem with changing Label in Bridge CS3 and CS6 in windows.
1. In Bridge CS3 (Windows XP), most of the time with most of the files, there is no problem. But I found that in some files, the Label does not get changed. I usually change Label by right clicking on the picture, then Label and select any Label. When I do so in those files, nothing happens. But when I rename the file by changing or adding just a single character, then it works. And if I again rename to original name, it still works. But without renaming the Label does not change. Again this does not happen with all pictures, but occationally with some. We usually receive pictures from different clients for editing purpose.
2. In Bridge CS6 (Windows 7), if you create lot of Path using Pen tool in Photoshop for the purpose of removing background, you save the file, close, and change Label in Bridge, again open the file in Photoshop, you see no Path in the Path Pallette. So that means, changing Label works, but it removes the Path from the file. But if there is small amount of path, then no prboblem. But if there is lot of path, like you need to create for a necklace to remove background, then the problem arises.
I am using Bridge for a purpose where it is very helpful so I really need to use Bridge, and Labeling feature is the most important to me, but after feaguring out this problem, I am really tensed as to whether or not I will find a solution to this. So any help, guidance will really be appreciated.
Thanks very much in advance for any solution.
Best regards

I have re-checked the issue and I found that the problem is with JPG file.
I wasn't even aware you could save a path to a jpeg file (always use PSD because of wanting to keep the Alpha Channel, jpeg only can contain 1 layer and no alpha channels and/or transparency).
However I tried it on a file with a simple path and one with a complex path. It seems indeed you have found a bug. The simple path is no problem but the more complex path is indeed disappearing.
It is not only label but also rate or adding IPTC in the description field. The moment metadata is saved to this jpeg file and reopened the earlier present work path of a more complex path is gone.
Despite the fact that to my opinion a jpeg is not the most suitable file format for saving a work path this should not happen. If a work path is saved to a jpeg then it should be kept saved after just altering metadata in Bridge.
It still is the same behavior in Bridge CC because that is what I use. Don't know when it started but it still needs to be repaired

I bought my iphone unlocked from carephone warehouse, I had a problem with the phone and apple swapped it over but they locked it to tmobile!!! what can i do?? I have changed contracts and can not use my phone!

I bought my iphone from carephone warehouse, sim free and with no contract. 5 months down the line I had a problem with the phone and I booked a genius appointment, they swapped my phone and gave me a new phone but they locked my phone to tmobile!!! I now do not use tmobile and I have an iphone which is locked to tmobile!!! I bought an unlocked phone and apple have locked it!!! what can i do?

In response to this, Carphone Warehouse (and Phones4U) sell what is commonly referred to as "sim free" handsets - these are not the same as unlocked. Sim free handsets will automatically lock to the first network sim card that the phone is activated with, and that will be permanently. The only way to unlock the handset would be to go through the network (T-Mobile I understand) and request they unlock it for you. More than likely, there will be a charge as you are no longer a T-Mobile customer.
If you ever want to purchase a new unlocked iPhone, the only place you can buy one is from Apple directly. Any other place will most likely sell sim free handsets.

[SOLVED] KVM and Bridged Networking

I've got KVM working and a Windows 2008 server installed on a image now, but it's only getting a NAT ip address. I need to get this server onto my main network, on Windows I'd use Virtual Box and Bridged Networking, but I thought I'd give KVM a try out.
I've followed the setup at https://wiki.archlinux.org/index.php/KV … Networking
Using Netcfg
Bridged networking is used when you want your VM to be on the same network as your host machine. This will allow it to get a static or DHCP IP address on your network, and then you can access it using that IP address from anywhere on your LAN. The preferred method for setting up bridged networking for KVM is to use the netcfg package. You will also need to install bridge-utils.
Netcfg#Configuring_a_bridge_for_use_with_virtual_machines_.28VMs.29
And this page https://wiki.archlinux.org/index.php/Ne … _.28VMs.29
I've got a bridge working I believe (all my stuff is DHCP by the way)

I've got "bridge" added to my rc.conf as a MODULE which is loaded. (I saw reference to this somewhere else on the forum that this might be needed)
I'm starting my VM with the following command
qemu-kvm -vnc 192.168.1.52:0 -hda Nekomi -m 2048 -smp 2 -net nic
Yet I still can't get an IP outside of the 10.0.0.0 range on the VM.
The VNC line above is because the HOST has not VGA output at all, completely headless.
I'm trying to get this working and trying to learn at the same time. KVM is new to me, as is bridged networking on linux.
Any ideas? Thanks

Sorry for the delay, bit a PC rebuild occurred :-(
Anyway, I managed to get this working with steps #1-#7 from the linked section. Thanks for that. I did have a few minor issues in getting a DHCP on the host machine itself, turns out I'd missed a single ) from the daemons section of rc.conf. A human error, but difficult to fix as the machine was rendered off the network and without a VGA card... fun!
I diverge, I have this script to bring up a bridge when the qemu-kvm starts
#!/bin/sh
echo "Executing /etc/qemu-ifup"
echo "Bringing up $1 for bridged mode..."
sudo /sbin/ifconfig $1 0.0.0.0 promisc up
echo "Adding $1 to br0..."
sudo /usr/sbin/brctl addif br0 $1
sleep 2
But when the kvm shutdowns it complains it can't find qemu-ifdown script. So I'm thinking of making one but just want to check it over first.
#!/bin/sh
echo "Executing /etc/qemu-ifdown"
echo "Removing $1 from br0..."
sudo /usr/sbin/brctl delif br0 $1
echo "Taking down $1 from bridged mode..."
sudo /sbin/ifconfig $1 0.0.0.0 promisc down
sleep 2
I've reversed the logic here, is the above the correct way to bring down the guest interface?

Problems with Customer Service AND unexplained charges!

I've been with Verizon for I-don't-know-how-many years, and through the years you are bound to have a few problems here and there but some of the problems are just ridiculous! It's also the same reocurring problem!!!!!!!!!!!!!!!! I was with Alltel first, before it was bought out by Verizon. The years I was with Alltel, I didn't have near as many problems. It seems EVERY time I do the smallest change or something to my phone or bill, I get a ridiculous amount of charges that I was NOT aware of, nor told about... EVEN IF I ask "So this isn't going to change my bill, or there will not be any unexpected/unexplained charges that I don't know about?"... BUT not matter how many times I ask... and NO matter how many times I am told "no"... there always is. For example.... last year, I updated and signed a new 2 year contract and purchased the first Driod. Before, my 30 day warranty was up, I was having problems with my Driod, and decided to send it in and get a new one. Before I did this.. I called customer service to make sure there would be no interuption in my bill, and there wouldn't be any unexpect charges, and there would be no difference in anything. I was told there was not, and once I recieved my new phone, just send it in and nothing would be changed. Of course, when I get my bill.. I see I was charged $500 for the new phone. It was explained to me that my credit card was reimbursed (which I never check that card, because I never used it expect to purchase the phone) and that I was recharged for the new phone, since it was a new phone. So I had to fork out the $500 (on top of my bill) and then wait months to get the $100 rebate card. Months after that, I "assumed liablity of my line" because I was on a plan with my family. I decided to have my own line, so I "assumed liability." I was not told that when I did that, I "renewed" my contract date. So I just added 6 more months to my 2 year contract. Was NOT told about that! Then again...... I was recently having problems with my Driod (the screen went black and would not come back on.) I had to turn on an OLD motorola razor, so I would not be without a phone for two days while I was waiting on my phone to come in. As soon as my phone came in, I had my Droid turned back on. I recieved my bill recently, and my bill was $200 over what it normally should be.... so I called in... apparently, when I had my phone replaced, they dropped off my data package and when I recieved my replacement driod, they never put it back on. So I was being charged for alllll my data usage... again I was NOT told about this. I wasn't even aware that they had dropped off my data package, and when/where did they get the authority to do that??? These are just a FEW of the problems that I have had.................................
Does anyone have these reoccuring problems!?

I understand that my bill can be viewed online, and I do view it fairly regularly, so if there are any unexplained charges, I can call Verizon asap. The problem does not come from me not understanding my bill, but from customer service. I have been with Verizon for a very long time, and it is a continuing problem. Where did Verizon get the 'OK' to drop my data package off my plan? Who authorized that?
After calling Verizon and trying to find out the problem, the gentleman told me that when I activated on old phone while I was waiting on my new Droid to arrive, my data package was dropped off and I "should" have been told about that. When I reactiviated my new Droid, I "should" have called and had them restart my data package. I was not aware that when you activate an old phone that data plan is taken off your plan. In all my years of having cell phones, I never make two years with one phone. I have always, at one point, had to turn on an old phone, and my data package has NEVER changed. Why would I have my data package dropped and why would I have to call Verizon to have it restarted. I would never know to do that unless I was TOLD that my data packaged HAD to be re-added when I recieved my new phone, but I was never told of that.
All of that is beside the point, the point is, Verizon was never given the authorization to change my plan. Never. My bill was taken care of and readjusted, and I am thankful for that. It does not change the fact it is always a hassle with Verizon Customer Service and I am always the one having to PROVE that I am not at fault, or that I was NEVER told of certian things. EVERY TIME I HAVE CALLED CUSTOMER SERVICE, I AM TOLD "I'M SORRY, THEY SHOULD HAVE TOLD YOU THAT."
"they should" does not help my bill with the extra armount of charges.

Problems with dropped calls and no reception on Samsung Continuum

My mother and I both purchased a Samsung Continuum in late March 2011, and have experienced the same problems with the phone. The device drops at least 2-3 calls per day, often on the same conversation; we have not found that location or time of day makes a difference. The phone freezes up frequently, even if no apps are running in the background. We lose our 3G network reception frequently, and cannot access our texts, emails, or the internet. The screen saver kicks in even when we are actively dialing a number, or typing in a text message. The overall performance of the phone is also poor, and it is quite slow much of the time.
We have raised this issue several times with a representative at one of the Verizon stores, but he states that he can find no problem with the phone, and that these issues may not be covered under our insurance plan. None of my friends with non-Samsung phones are having the same problems with phone reception and performance. I am aggravated enough with these issues that I am considering reactivating my old Blackberry, which worked like a charm.
I am not upset that my phone has not been updated to Android 2.2. I just want the phone to perform as stated, and not fail at its primary function: making and receiving phone calls. I am not certain if these problems originate with the phone, Verizon, or Samsung, nor do I care. I just want to resolve these issues as soon as possible, or I will have to look at other alternatives.
Thank you.

If this doesn't work...now what??? I have a useless $400 plus piece of unreliable junk. My Motorola Razor was ions more reliable than this phone...very, very sad but true.
What carrier were you using with the Razor? AT&T? Same area?
