Magic number mismatch: bad mzip file in 3750 stack switch

Hi All can anybody help me in this error msg
"magic number mismatch: bad mzip file"
I am trying to upgrade the switch with"c3750e-ipbasek9-tar.122-55.SE5.tar" in 3750 stack switch it is showing this error msg while booting
thanks in advance

Hi,
The reason you are getting this error message on the switch is a corrupt or wrong IOS image "c3750e-ipbasek9-tar.122-55.SE5.tar".
If the switch is in rommon mode, and you have any other image in the switch, boot it using that image. Once the switch is up, download and copy the correct IOS image once again on the switch and try to upgrade.
If you need help in finding the correct IOS image, give me the exact switch model number, i will help you with that.
But forsure the image is wrong or corrupt and that is why you are getting this error.
Thanks

3750-PoE bricked - Magic number mismatch?

Hi,
I have a 3750 PoE which I was trying to get the image off by doing a archive upload-sw...... but as it got to the image file it said the file/device was busy and gave up.
I executed the reload command and since then I've had this error message which doesn't allow the switch to boot its IOS:

LWAP migration of AIR-1131AG-A failed bad mzip file

Hello Experts,
I would like to connect a Cisco LWAP 1131AG-A-K9 with a WLC4402 running on 4.1.171.0
Unfortunately, the software downloaded from the WLC is not correctly unpacked on the AP.
I can see an error on the console stating "bad mzip file".
We did several test with converting back to autonomous and migrating to LWAP again using the Cisco Upgrade Tool
but we are failing constantly, even though the Cisco Upgrade Tool states a successful update.
All our european Cisco LWAPs 1131AG-E-K9 are running fine by the way on the controller.
I have added the Console messages to show the error to You.
Who knows anything about that ?
Please support.

We are using right now only Lightweight-APs with ETSI-Standards on several Controllers without having that problem.
The problem appears during the migration from AUutonomous to Lightweight of an 1131AP with American-Standard.
The according WLC is configured to support US-Country of course.
I cannot believe that this is the problem. This would mean different LWAPP-images per regulation domain.
Who knows more about this damned mzip-error during the extracting phase of the LWAPP-image ?

Visibility of 3750 Stack Switches on SCH Portal

We have implemented Smart Call Home in one of our customer network. Customer has 34 3750 switches configured in stack. We have done SCH configuration for all 34 devices, problem over here is on SCH portal under “Global Summary Report” only 17 switches are reflecting however in “Device Report” all 34 devices are reflecting.
Can you please confirm/suggest to whom we can coordinate to resolve “Global Summary Report” discrepancy issue.

When a stack boots, each stack of switches determines a master switch. The master switch is the switch handling coordination for all of the other switches in the stack and outside communication.
It looks like the global summary report is reporting only the master switch for the stack. This makes sense to me. All of the other switches in the stack are suppose to be invisible to the outside world and the stack is supposed to operate as a single virtual switch. Since it is a virtual switch, each virtual switch should be counted once as a single entity.
All of the devices in the stack are available for view if you drill down, but from a Smart Call Home view, only the stack master is communicating with Smart Call Home.
But the bottom line is this is only software and can be written differently if it is too confusing to the customer.

3750 Stack Switch Issue

Hi
I have Stack of 7 3750 Switches. In that Switch 1 is master with 15 Priority and other switches are Member but because of some reason switch 1 rebooted and then Switch 2 becomes Master because it’s having 14 Priority.
We have 2 uplinks which connected on switch 1 (1/1/1) and switch 6 (6/1/1) Tengig port. Also we have 4 AP connected on switch 6.
So we observed that the Switch 1 came up and after that 3 AP is disconnected from WLC. if we disconnect the uplink port on Switch 1 (1/1/1) AP will connect the WLC and using uplink 6/1/1 but if we connect uplink port 1/1/1 and disconnect the uplink port 6/1/1 all 4 AP will disconnect from Network.
We try to connect the Uplink 1/1/1 to Switch 1 other port 1/1/2 but face the same issue. So we reconnect the port 6/1/1 and used the same link which connect on 1/1/1 to switch 7 (7/1/1) and AP will connect on WLC. So as per this troubleshooting we thought some issue with Network Module or Switch of Switch1.
So we Swap the Network module between Switch1 and Switch7 and connect the uplink on 1/1/1 but face the same issue and if we connect the same uplink on Switch 7 Ap connect to WLC.
So we thought that Switch is having issue. But before raising an RMA for Switch we observer 1 more thing that. Earlier that when the Switch 1 is Master all 4 AP's connected to WLC and working fine but when the Switch1 became rebooted and Switch2 became Master issue started. So we rebooted the Switch 2 and make switch master and found that while connecting on port 1/1/1 of Switch port AP's are able to connect to WLC and Issue resolved.
So I wants to know that is there any requirement that If the high priority switch rebooted and after came up it should not be Master then connected uplink will not work.
Also let us know what’s happen if the high priority switch came up in network. Means it’s will became Master or Menber.

Just now i Found one bug which is matching on our issue.
3750x stack fails to update ARP table after reboot causing traffic loss
BUG ID:-CSCtz98066
Symptoms: When the master switch (Switch A) is reloaded or loses power and
rejoins the stack as a member switch, any traffic stream being sent through
Switch A is unable to be received by the destination because the newly joined
member is not able to establish an ARP entry for the next hop router/switch.
Debugs confirm that Switch A does not send a GARP/ARP for the next hop, though
traffic continues to be sent to the switch.
Conditions: The symptom is observed when only Switch A has a physical
connection between the source and destination router/L3 switch. The newly
elected master (Switch B) does not.
Workaround: Ping destination from Switch A, forcing ARP request/response.
Also affected version is 12.2(58)SE and15.0(1)SE2 and we are using IOS 12.2(58)SE.
So we are going to upgrade the devices by this weekend with IOS 15.0(2)SE5.
Will update you once we upgraded the switches.

Power Redundancy problem for cisco 3750 stack switches

Hi Team,
I have installed and configured cisco 3750X series switches in stackwise. Those are having dual power supply.
Power redundancy test performed:
1. Removed one of the power supply and inserted it back.
2. once the first power supply is ready, removed another power supply and switch got rebooted.
please find the below stack-power output:

Magic number for vi

I'm often using the command "file" (on a linux box) to dertermine the
type of a file.
Ok, LabView vis are easy to find because of the file-extension (if there
wasn't some moron changing it).
Is there a magic number (or a magig-file) which contains a definition
for LabView vis, so they would be known by "file"?
Or, if there isn't such a finished file... how can one see by the conten
of the file (not by it's name) if it's a LabView vi?
thanx and bye
Marco

To be accurate, the Carriage Return and Line Feed are followed by a
16-bit integer before "LVINLBVW".
Further, I think LLBs differ from VIs (in these first few bytes) only
in that "LVIN" becomes "LVAR".

Catfish - RuntimeError: Bad magic number in .pyc file

I'm using catfish as a search tool, I installed it on a new system with findutils as the backend. When I run it I get "RuntimeError: Bad magic number in .pyc file"
I have no idea how to fix this. It runs fine on another system. I tried to reinstall it and did a full upgrade. I tried it with various backends and I still get this runtimeerror. Any ideas?

See if you can locate a leftover .pyc file with:
pacman -Qo $(find /usr/lib/python2.{5,6} -name *.pyc) | grep "No package owns"
Provide pacman manages all files on your root partition, it should be fine to delete what this finds.

Bad Magic Number error trying to deploy WAR file from Netweaver Studio

We hae an application that runs fine as a WAR in both Tomcat and Weblogic and we are trying to deploy it on Netweaver. I tried both to use the External deployment archives and the Workspace Deployable Archives. In both cases, the deployment fails with error:
Bad magic number, found 0x80CCF1C3, expected 0xCAFEBABE.
I know the server is working because I can deploy a very simple test application with no errors. The server is a new installation of 7.1.
Any help on how to get past this error or how to troubleshoot further is appreciated.

Looks like it's complaining about a missing shared library. Check weblogic.xml for library-ref elements and make sure the domain you are deploying to has those libraries deployed.

Bad magic number

I have an applet that i am trying to load in a JSP
<applet name="MyTestApplet" code="mypackage.MyTestApplet.class" >
</applet>
mypackage/MyTestApplet.class is under the approot/pages directory and the jsp is also in the same directory.
whenever the jsp is called and applet does not get inited and the error i see is a ClassFormatError: Bad magic number
Please help.. this is extremely urgent.
Thanks in advance for any input anyone may have.
The appserver i am using is SunONE

First the <applet tag is depreciated, you should use <object instead (w3c has depreciated applet for quite
some time now).
When I see the tag you don't use a jar package (archive is missing) so let's pretend the url to your page is
http://mysite/mypage.jsp
the mypage.jsp contains the applet so the url to the applet is:
http://mysite/mypackage/MyTestApplet.class
can you download the file using a browser?
you can do this by saving the following line in a html file and right click it then sava target
right click and save target as
After downloading is the file the same as the file on the web server?
The reason I ask this is because I got the bad magic number when a jar was loaded through a proxy.
The proxy did something with the jar file making it corrupt. I think your problem has something to do with
the way your web server is serving the applet or (proxy) something between the client and the server.

JVM issue with applet - Duplicate Key in Parameter Table - Bad Magic Number

Hey, I have Googled this one to death and have seen a few vague references to this problem, but nothing I can relate back as solution.
I wonder if I need to tell the customer to reinstall the OS and, ultimately, the JRE. I'm just looking for a little guidance on what any of you may think. Am I missing a setting or something?
The user is trying to download an applet with IE with 1.3.1_16 and Firefox 1.07 with the Java Embeded Plug-in.
Even though JRE 1.3.1_16, 1.4.2_09 and 1.5 are all installed and Firefox has the JEP also installed, Firefox still wants to use 1.3.1_16 as does IE. I'm guessing that the JEP didn't work.
They can't use Safari which does seem to be using 1.4.2_09 because their RSA ID won't authenticate through it.
On my machine, when I run with the same OS,browsers, and Java 2 plug-ins, I can successfully load the applet.
This is the error that the user gets in the java console is:
Duplicate key in parameter table: code using the htmlAttribute.
first: com.ibm.eNetwork.HOD.HostOnDemand
second: com.ibm.eNetwork.HOD.HostOnDemand.class
java.lang.ClassFormatError: com/ibm/eNetwork/HOD/HostOnDemand (Bad magic number) at java.lang.ClassLoader.defineClass0(NativeMethod)
at java.lang.ClassLoader.defineClass(ClassLoader.java:488)...
Would you reinstall the OS and Java? or look at another setting? or look at the JEP installation again?
Thank you.

Without reading the full post (sorry for that) my guess is that the applet needed to be fetched through a
proxy, the proxy corrupts the applet because it's signed (finjan is one that does that).
The reason why a proxy would do so is because the default settings of sun jre will ask the user the
"do you trust" question to the user which could result in the user loading an applet that is allowed to do
anything the programmer wants (4us, spyware, nasty stuff).
Try to do the following:
1. create a html file locally with the following content:
rightclick and save target as
2. open the page, right click the link and save the file
3. apen the file with an unzip programm (winzip) and check if the content has changed.
4. If the content has changed than the proxy might have done this, contact the system administrator
It might allso have been done by a firewall installed locally.

Java.lang.ClassFormatError: HTML (Bad magic number)

hi,
i have quite a strange problem:
when my applet tries to parse an XML file with SAX (no DTD-validation) i got the following error:
java.lang.ClassFormatError: <HTML> (Bad magic number)
Well i had some problems before with the ClassFormatError but they were because some class-files were corrupt. They were easy to fix because the defecitve class-file was written next to java.lang.ClassFormatError. This time i got the <HTML> expression next to the error. what does this mean?
thnx in advance!
marc

Bad magic Number. means the first 4 bytes did not equals CAFEBABE (0xCAFEBABE) But why do you see <HTML> after that is beyound me. Can you locate which class is foul and replace it?

debugs say superblock is ok but unable to mount the partition :
mount.ocfs2: Bad magic number in inode while trying to determine heartbeat information

E2fsck: Bad magic number in super-block

e2fsck: Bad magic number in super-block while trying to open /dev/hda1
Yup, a very tricky one this is. I did the following:
[root@(none)~]#e2fsck /dev/hda1
e2fsck 1.40.2 (12-jul-2007)
/dev/hda1: clean, 310310/4702208 files, 8118002/9396009 blocks
What can I do to fix the super-block? I unable to boot up my system right now, and I can't afford to format my disk.
I have systemrescuedisk with the TestDisk application at hand(if needed?).

B wrote:There is a backup superblock every 8192 blocks if i'm correct. So the next one is at 8193. Try telling e2fsck to use that to fix your partition.
I've tried that, with no luck I'm afraid. So I've gotten more serious and.
With Testdisk I managed to indentify these superblocks.
[Superblocks] where * means it has been e2fsck'ed

32768, blocksize=4096*

umount /dev/hda1
e2fsck -b 32768 /dev/hda1
/dev/hda1 was not cleanly unmounted, check forced.

I get the question:
Free inodes count wrong for group #1 (ie. 32254, counted=231)
Fix<y>? y
This question got repeated #286 times, where I answered the same (y) each time.
/dev/hda1: ********* FILE SYSTEM WAS MODIFIED ************
/dev/hda1: ********* REBOOT LINUX **************
/dev/hda1: 310310/4702208 files (1.5% non-contiguous), 8118002/9396009 blocks
So i rebooted... but still the same error occurs during kernel boot. So now I figured I had
to do the same with 98304 and so forth. YUP! I was right, this superblock was dirty too.
e2fsck -b 98304 /dev/hda1
answer yes to all. Reboot, and repeat with 162840. Until your kernel manages to mount
your disk cleanly and hopefully boot up.
Sadly when I e2fsck -b 98304 /dev/hda1 yet again just to check, it still claims to be dirty.
Now I'm kinda back to where I started.
I will look further into if testdisk can provide some automagic solution to my problem.
Pointers is apprecieted!

T6340 cannot boot disk - Bad magic number in disk label

Hi,
I have a shiny new T6340 that I am just setting up.
When I get through the CMM to the SP and onto the EEPROM,
I then try to start the boot process:

Please tell me what I need to do to enable the disks, so I can do the next bit!

@rachel,
In your original post you showed a screen capture of what you tried.
First you typed "boot disk1". ( Why disk1? Why not disk0?)
When that didn't seem to work, you displayed the disks recognized by the system at OpenBoot.
The first of those disks was a device path of
/pci@500/pci@0/pci@9/LSILogic,sas@0/disk{code}
and so you attempted to boot from that but omitted whatever slice might be the boot slice of a factory preinstalled OS. For example...
{code:java}
boot /pci@500/pci@0/pci@9/LSILogic,sas@0/disk@0,0{code}
(just guessing at what could be that bootable slice).
What happens if you simply type "*boot*" when you are at OBP?
