Weird Behaviour on Catalyst 2950

Dear all,
Need your comment in this problem. Yesterday , while users were connected to the network,suddenly they experienced a drop of connection ; i.e they were disconnected from the network.Upon observation, we realised that the 2950 catalyst switch rebooted a few times even though we didn't disrupt the power cable.
After performing "show version" on the switch, we found out this line " System returned to ROM by error - signal 10, exception code (0x0008)! , pc0x8043B7DC" but we could not find the meaning of this alert through the Internet. Does anyone know what it means?

Here is a possible candidate:

Error and weird behaviour in executable launch

Hello folks,
This post is regarding a weird behaviour i am experiencing with an executable i built.
LABVIEW version(Includes Runtime engine) LV2012 SP1 f3
DAQmx: 9.6.1
The behaviour is listed below in detail.
In a nutshell, the exectuable runs on the development computer but does not run on the Target computer. Also, Irresepctive of which PC i run the executable on, i cannot access the block diagram even after enabling debugging everywhere.
On the target PC, the app fires up but does not run further, no error codes appear on the screen, it's like the app freezes after firing up. And to add to the misery, i cannot access the block diagram to debug and know what's going on.
Also, I have tried including the dynamic vis to my build script. No bueno.
What I see on running the app is addressed below:
TARGET COMPUTER:
DAQmx 9.7 and LV2012 SP1 f4 RTE have been installed manually.
App does not run: No broken run button, the app launches but does nothing when the vi is run. No error messages.
The block diagram is still inaccessible, even after selecting the “Enable debugging” option in the build specifications.
DEVELOPMENT COMPUTER:
The app launches and runs perfectly.
The block diagram is still inaccessible, even after selecting the “Enable debugging” option in the build specifications.
DAQmx 9.7 and LV2012 SP1 f4 RTE were not installed as the app recognized the already installed Labview environment.
Additional steps that I have tried,
Created and ran only an executable on the target PC, the attempt was unsuccessful. The vi showed similar characteristics as mentioned above in the target PC section.
Created and ran an installer with additional install options(LV2012 f4 RTE and DAQmx 9.7)on the target PC, the attempt was again unsuccessful. The vi showed similar characteristics as mentioned above in the target PC section. No error messages.
Tried both the steps mentioned above on the development computer and the attempts were successful. .
To the best of my knowledge, I believe, the issue here is with the environment I am creating for the executable and the installer to run with/off of. After having carefully followed the installation procedure for the Run-Time Engine and the DAQmx drivers, I still do not know what I am missing.
Please advise.
Thanks guys,
RP.

Hey guys,
So, got the application to work. Almost.
The problem was that the executable was missing the hardware config from the Device.
Now, the new issue is as following:
The goal of the vi is to generate a report of the test conducted. So, the way the vi works is that, the second the vi is run, an empty word file is created with only the company logo,
Field headings, which are populated after the test is conducted.
The logo is a .jpg file, which has a relative path into the executable.
The field heading are String constants wired into a 'concatenate strings.vi' which are in turn wired to into the report generation vis.
What's happening is that when i run the app on the target pc, Only the logo appears on the word template. Even when i conduct the whole test and stop the vi, the results aren't populated in the word file. Which is a little weird.
Does any one know whats doing that?
Please refer to the attached word files.
Right - It is the file format desired.
Wrong - It is the file format achieved.
Please advise.
Thanks,
RP.

[Solved] Firefox 3 betas give me some weird behaviour with images

I understand that there will be problems with beta software, however I seem to have memory issues with the firefox 2 series, so I thought I'd give the beta packages a try. I'm using the firefox-nightly package from AUR (firefox3b4), and I'm getting some weird behaviour. The same behaviour can be seen in all firefox 3 beta builds, however. It's hard to explain the problem, so here's a screenshot:
Notice that the image appears twice, once in the tab, and once in the tab toolbar next to the title of the tab. It looks like an attempted preview gone terribly wrong. Upon closing the tab, the tab toolbar shrinks down to the normal size and all is well. This happens with most images up to a certain size. Any one else experiencing this problem? Any suggestions? This is very annoying and I would like anyone's input on the problem.

Wow! This issue was solved in #archlinux by Nuked. Apparently I had some funky bits in my .mozilla directory. Removing it solved the problem. Remember kids, IRC is your friend. Anyone else experiencing weird stuff with their Firefox install should give this solution a try.

Cisco ISE and Catalyst 2950

Hello!
Please, could you help me? Is it possible to install ISE on Catalyst 2950? In Component Compatibility Guide
http://www.cisco.com/en/US/docs/security/ise/1.0.4/compatibility/ise104_sdt.html
Catalyst 2950 only support 802.1X and VLAN.
At first I need to know about VLAN change(from resticted to corporate). Is Catalyst 2950 support it?
Thaks for help!

this would let both user and machine authenticate. for"5434Endpoint conducted several failed authentications of the same scenario" check Suppress Anomalous Clients option. This issue comes in to picture when endpoint attempts a couple of failed authentications and if Suppress Anomalous Clients option with Reject Requests After Detection is enabled then ISE Policy nodes protect themselves from overwhelming numbers of authentication requests by sending an immediate reject for suppressed clients as opposed to processing all the steps in a normal authentication. So if that user did some authentication failure, he will be locked for 1 hours (bydefault).

HTML Link -AS2 fine, AS3 weird behaviour

Hi Guys, I'm working on a project at the moment, and am
seeing weird behaviour with the way my swf handles html links
inside dynamic textboxes. When rendered as a AS2 file, the link
works on a release as expected. When its inside a AS3 file the link
will only work if the user right click and chooses 'open in new
window' was there a change in behaviour how AS3 handles these
links, or is there now an declaration needed to be made to allow
these link to have the old behaviour?
The project calls for xml data and embedded in that is a html
link. Originally I thought it might have been the way I'd formed
the xml so I tried with a hardcoded version instead (dynamic
textbox, add text -> highlight -> add link through properties
tab). But I still see the same behaviour between the as2 and as3
versions.
Any help would be greatly appreciated.
Cheers.

Actually, the ''href'' attribute is supposed to direct the browser to a new URL, etc., not run a script. Instead, use the ''onclick'' event attribute:
''<a onclick = “$('.div-feedback').fadeIn();”></a>''.
Happy coding!

Weird behaviour in the Fontbook display pane

I have just been checking through some font conflicts using FontBook. All have resolved successfully, but I have noticed weird behaviour involving four or five fonts. Some of them show up as all-Cyrillic faces (Arno Pro), or all-Hebrew faces (Stone Sans) or all-Arabic faces (Balzano) in the display pane, yet print perfectly as Western characters when used in any program (Pages, Word, Bean, FCE, Keynote etc).
It's not actually causing any problem, I suppose, apart from a weird representation in Fontbook. I have tried deactivating and reactivating these fonts. I have tried quitting and restarting Fontbook. I have even tried restarting the computer. The Cyrillics, Hebrews and Arabics keep coming back.
Is this a known Fontbook bug, or am I doing something wrong?

Thank you, Kappy and Tom:
I tried the Preview Repertoire command and it showed that the fonts did, indeed, have the full Latin complement of characters. It's just that only the Cyrillic/Hebrew/Arabic/Gujarati/Mandarin selections are showing up in some fonts' preview panes: particularly those fonts with the suffix "Pro" in the title (Myriad Pro, and so on).
How strange.

Weird behaviour in report filter with Presentation variables

Hi All,
I'm facing a weird behaviour on filtering the report using presentation variables
Prompt:
1. Start Date assigned to PV_ST_DT
2. End Date assigned to PV_END_DT
Report
In the filter section given the "between" condition with these two presentation variable
Fiscal Date between {@PV_ST_DT}{01/01/1990} AND {@PV_END_DT}{01/01/1990}
this given filter condition results in the report like
Fiscal Date is equal to ({@PV_END_DT} value)
the filter criteria is not applied as I given, I have tried by changing the conditions like greater than or equal to , less than or equal to. The filter applied only the last presentation variable value with the prompt condition, It is not taking the condition specified in the report.
Can anyone provide a solution on this?

Below format: works perfectly fine
Fiscal Date BETWEEN '@{PV_ST_DT}{01/01/2007}' AND '@{PV_END_DT}{01/03/2007}'

Weird behaviour in RMIClient

hi all,
i am experiencing a weird behaviour with my RMI Client....
my RMIClient has two methods
init()
callRemoteMethod()
ideally in the init() i should locate the RMIServer, and in the callRemoteMethod() i should call one of hte methods of the RMIServer
the problem is that it does not work!!
my RMIClient code works ONLY if i put the initialization of the RMIServer and the call of one of its method in the SAME method
is it normal that it happens like htis????
can anyone give me some hints??
thanx in advance and regards
marco

hi all,
i solved the problem...i was initializing hte RMI server twice.....
sorry for bothering

Catalyst 2950 Switch flash_init error

Hi Everyone,
I'm new to Cisco products and have a small home lab set up. I have a Catalyst 2950 switch that I would like to restore to factory defaults. Here is the issue I'm having and can't figure out.
I pull the power, telnet into the console port, hold the mode button and restore power. The boot loader (Version 12.1(11r) starts and says the usual message the system was interrupted prior to flash initialization (Paraphrasing here)
I get to the switch: command line, enter flash_init. Flash states it initialized and then all I get is a < with an underscore under it prompt. Anything I try to type comes up as bizarre characters and I can not get back to a switch: prompt unless I reboot the switch manually. Unsure of what to do here.
Thanks in advance!

Hi mattymattlynch
Check the workaround on the following documents:

If no luck , the flash might be corrupted and requires a replacement.
Hope this helps

SQL MP - SPN Status monitor weird behaviour

Hi all,
I have a strange behaviour with the monitor that checks SQL 2008 SPN status. More precisely I have a weird behaviour with the script used by the monitor. The script is GetSQL2008SPNState.vbs. I configured the SQL monitoring profile (which is used by the
script) with a domain account with necessary rights.
Let's say I have a SQL Server called SQL1. SQL1 is in domain AD1. I have a forest called contoso.com with two child domains AD1 and AD2.
On SQL1 I sometimes see events 4001 generated by this script that mentions a problem to connect to WMI namespace (which is healthy, I checked with wbemtest). The event says that it couldn't connect to
\\SQL1.AD1.contoso.com.AD2.contoso.com\root\blabla. I have no idea why it is using that broken FQDN.
I made some research into the script and understood the following:
The script has the SQL server FQDN as parameter (here SQL1.AD1.contoso.com)
It searches the defaultnamingcontext by doing
Set oRootDse = GetObject("GC://RootDSE)
sRootnamingContext = oRootDse.Get("defaultNamingContext")
It converts the defaultnamingcontext variable from "DC=a,DC=b,DC,c" to ".a.b.c"
It checks if the defaultnamingcontext is in the fqdn and if not it appends it at the end of the fqdn. Dunno if I'm clear here so here are examples of good and bad behaviours:
GOOD:
FQDN is SQL1.AD1.contoso.com, defaultnamingcontext gives AD1.contoso.com, AD1.contoso.com is in SQL1.AD1.contoso.com so the script go on using SQL1.AD1.contoso.com and it's ok...
BAD:
FQDN is SQL1.AD1.contoso.com, defaultnamingcontext gives AD2.contoso.com, AD2.contoso.com is not in SQL1.AD1.contoso.com so the script go on using SQL1.AD1.contoso.com.AD2.contoso.com and it's broken...
I didn't mention earlier but the runas account I use is from domain AD1. It's called AD1\svc_scom_mp
My question is how comes sometimes (sometimes means during 6 hours, a whole day, nothing reccurent :( ) The defaultnamingcontext gives me the fqdn of the other domain ??
I'm wondering if this can be due to the fact that I also have an account called svc_scom_mp in AD2 but I'm 100% sure it's not used here as it's not targeted nor distributed to any AD1 computers.
I guess it's more an AD problem than anything else.
Any ideas ?

Hi François
I tested GetSQL2008SPNState.vbs on my POC with a similar configuration (one root and two child domains) and i have got the same issue. I think the root cause is the Server less binding (GC://RootDSE) used to search defaultNamingContext.
With Server less binding, GC name relies on
DNS round robin to find a GC, if a GC from another domain is returned the defaultNamingContext will be the other domain.
You can check GC resolution with nslookup:
nslookup gc._msdcs.contoso.com (the root domain)
repeat the command to see the round robin result.
I wrote a vbscript to test it:
This script search all GC and search defaultNamingContext with GC provider server less and server name binding. With LDAP Provider the right domain name is always returned.
=============================
ldapFilter = "(&(objectClass=nTDSDSA)(options:1.2.840.113556.1.4.803:=1))"
Set rootDSE = GetObject("LDAP://rootDSE")
configDN =   rootDSE.Get("configurationNamingContext")
Set ado = CreateObject("ADODB.Connection")
ado.Provider = "ADSDSOObject"
ado.Open "ADSearch"
Set objectList =   ado.Execute("<LDAP://" &configDN& ">;" & ldapFilter & ";distinguishedName;subtree")
' GC Server less binding LDAP
      Set oRootDse = GetObject("LDAP://RootDSE")
      If Not (oRootDse Is Nothing) Then
            sDefaultNamingContext = oRootDse.Get("defaultNamingContext")
            wscript.echo "Server less binding:
LDAP://RootDSE"
            wscript.echo "   DefaultNamingContext found: " & sDefaultNamingContext
             wscript.echo " "

      If Not (oRootDse Is Nothing) Then
            sDefaultNamingContext = oRootDse.Get("defaultNamingContext")
            wscript.echo "Server less binding: GC://RootDSE"
            wscript.echo "   DefaultNamingContext found: " & sDefaultNamingContext
             wscript.echo " "
      Else
            wscript.echo "   NOT found: "
      End If
wscript.echo "Server Name binding: GC://<ServerName>/RootDSE"
While Not objectList.EOF
    nTSDSA = objectList.Fields("distinguishedName")
    serverDN = Mid(nTSDSA, 18)

Cisco Catalyst 2950/2960/3750 Multicast Traffic Preference

Hello all,
we, as a student company act as an ISP for university dormitories. We would like to (if it's possible) deploy QoS to prefer multicast traffic over all other types of traffic.
Devices used in network:
Acces layer: Cisco Catalyst 2950, 12.1(22)EA14
Dristribution layer: Cisco Catalyst 2960G, 12.2(58)SE1
Core layer: Cisco Catalyst 3750G, 12.2(52)SE
Do you see any possibility to solve this with these devices? We have almost no experience with QoS, therefore any help would be greatly appreciated.
Thanks in advance.

Hmm, I think it should be doable although the 2950s, if non-E variants, are especially weak in QoS features. I.e. those might create some issues.
With the 2960G and 3750G, you often will create problems when you enable QoS because QoS, by default, allocates its buffers resources for 4 egress queues per port rather than using all for 1 egress queue per port. However, this can be countered by QoS parameter tuning, but that takes some QoS expertize to match to your traffic and your overall QoS policy.

Roundness / Residual - weird behaviour

Hi,
I've been experimenting to understand "roundness" in Find Circular Edge - which seems to be the residual from "circle fit". I noticed some weird behaviour, and to understand it, I wrote a program that scales the width of a "perfect" circle from 0.5 to 1.5.
I expected some glitches, jumps,.. due to discretization, rounding,.. etc, but then I stumbled upon behaviour that makes no sense: When I detect a circle that is partly outside of the image, the roundness is suddenly at very low value.
To visulalize, I'm talking about such an image:
The roundness behaves like this:
I am not sure if it is just my vi (I'm attaching the example picture and the experimental vi), but can anyone explain this behaviour and give me some idea how to avoid it?
Thanks,
Birgit
Solved!

circularedge.vi ‏63 KB

The results of the "roundness" aka residual have a glitch once the detected circle is outside of the image.
Allow me to add a "normal" picture with a low residual of 0.17
High residual of 21,3
This behaviour sort of models how well the shape fits with the calculated circle.
And that's what I expect.
However, in the second the algorithm "finds" a circle that is outside of the image boundaries, the residual "jumps" and is suddenly very, very low, as if one had a shape that would fit with the calculated circle.
This, for example, has a residual of 0,27

[SOLVED] Weird behaviour after formatting USB installation media

Hi, I have noticed this weird behaviour with USB drives I used to install Arch linux with. I format them using fdisk and mkntfs but after replugging them in, the udevil daemon mounts them again as ARCH_2013...[something] and even the directory tree exists! This happens also when I use mkntfs without the -f flag (initializing with zeros). I also checked the other files in /dev/sd* in order to make sure that my drive does not appear twice, but there is only sda (my HD) and sdd (or sometimes sdb, sdc,...) which must be the USB drive, also according to dmesg.
Any ideas?
EDIT: I wrote something about not seeing any files when manually mounting but that was my bad, I only tried mounting /dev/sdb1 but mounting /dev/sdb brought me the same files as devmon showed.

I am assuming you used dd to write the image to the disk. You can use it to remove the contents of the disk as well.
You should make use of the arch wiki, it is quite helpful.
https://wiki.archlinux.org/index.php/US … tion_Media
You can use this to zero out the entire device:
# dd if=/dev/zero of=/dev/sdx bs=8M // x is the letter assigned to the usb drive. Be careful, The dd command is destructive.
It may take a while to zero out the entire disk, depending on the size. After that use fdisk/cfdisk or gdisk/cgdisk to create the partition table and partition.
To create the filesystem type, this one, ext4:
# mkfs.ext4 /dev/sdx // or create a vfat
then create the label:
# e2label /dev/sdx1 USB_STICK_LABEL
Use my suggestion as a last resort. Read the wiki, most of what I have said is in there anyway.
