ARP cache error

We have a SBS 2003 server running with a standard dual network configuration. One card for accessing the internet and the other card to connect the server to the local network.
We frequently lose our internet connection for an unknown reason (although the other card is fine and all client computers are still able to access the server -- they just loose internet access.)
We also receive the 'Clearing the ARP Cache' error message when trying to repair the connection.
However, instead of rebooting the server, we simply go into the Network Connections, locate the card that is for the internet connection, right-click and choose 'Disable', and then after it is disabled, right-click and choose 'Enable'.

Hi,
Before going further, would you please let me know if you have configured RRAS on your server? Based on your description, the problem can be caused if you are using RRAS as your basic firewall/NAT.
Please try the following suggestions to see if the problem can be resolved.
1. Firstly, we should make sure whether the network setting is correctly and properly configured. Please re-run CEICW Wizard on the SBS Server, it helps us automatically configure the network
settings, you can refer to this step-by-step article to finish the wizard:
How to configure Internet access in Windows Small Business Server 2003
http://support.microsoft.com/kb/825763/en-us
2. Please double check if you have correctly configured your DNS settings.
a. Leave the Default Gateway of the internal NIC blank on the SBS Server.
b. Configure both the internal NIC and the external NIC to use the internal DNS Service as the DNS Server.
c. On the DNS Server, create the DNS Forwarder to forward the external DNS resolution requests to the ISP's DNS
d. On the DNS Server, delete any public IP that is being registered in the local DNS.
3. Type "arp -d *" (without the quotation mark) from the command prompt. Then try repairing the network card again. If error still occurs, please turn to step 4.
4. Try turning off the "Routing and Remote Access" service, it can cause this problem.
a. Click Start->Run, type "services.msc", go and find "Routing & Remote Access", right click it and choose Properties.
b. Set start-up type to disabled and stop the service.
c. Then restart the computer which is mandatory in this case.
d. Try repairing the network card again, any luck?
If the problem persists, please help me gather the following information:
1. Does everything work normally before? If so, what changes have you made to the server/clients before the problem occurred?
2. Make sure that you uncheck "register this connections in DNS" check box from external NIC.
3. Confirm the connection binding order.
a. Please open Control Panel -> network connections.
b. Click Advanced -> Advanced settings
c. In the adapters and bindings tab, make sure that the internal adapter is on the top.

ARP cache poisoning error

Hi all,
I've googled and searched these discussions, but I can't find any pertinent info on this topic, so here's my question...
While looking into another issue, I noticed that my system.log had logged an error that concerned me:
*"Aug 4 12:03:52 localhost kernel[0]: Could not enable ARP cache poisoning detection. Your computer will not be protected."*
This message appears to only be logged on startup, and has been logged numerous times.
Does anyone know why this protection is disabled, and how I can re-enable it, if that's even possible (or necessary)?
Thanks!

IPMP / ARP Cache oddity - Solaris to Windows comm errors

First - a qualification - I'm not an Solaris admin, so feel free to call me out for any blatant errors..
I've got several Solaris 10 servers that are having intermittent network communication issues with Windows 2003 servers on the same subnet. All Solaris boxes are using two NICs and IPMP for their connections to the "primary" network. For example, one server (hostname bugbear) has two adapters ce0 and ce9:
# ifconfig -a
ce0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
        inet 16.106.64.227 netmask fffff800 broadcast 16.106.71.255
        groupname shared0
ce9: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 4
        inet 0.0.0.0 netmask ff000000 broadcast 0.255.255.255
        groupname shared0
# cat /etc/hostname.ce0
bugbear netmask + broadcast + group shared0 up
# cat /etc/hostname.ce9
group shared0 upIf I look at the arp cache, (almost) every other server it talks to shows up twice - an entry for each of the NIC devices:
# arp -a
Net to Media Table: IPv4
Device   IP Address               Mask      Flags      Phys Addr
ce9    win2k3box.city.acme.com 255.255.255.255 o        00:50:56:ae:13:58
ce0    win2k3box.city.acme.com 255.255.255.255 o        00:50:56:ae:13:58I guess that's as expected - again, I'm not a Solaris expert.
Finally, here's the issue I've found. For any other UNIX/Solaris hosts listed in the arp cache, my server can ping/FTP/whatever to the other - no problem. Sometimes the ce0 interface is listed first in the output for the target server, sometimes the ce9 interface is listed first. Doesn't matter - my server can talk to the other just fine.
HOWEVER - for Windows servers, the order of entry in the arp cache seems to have relevance. If the ce9 interface is listed first, I can't ping, can't FTP, can't connect to the other server. If the ce0 interface is listed first, then everything works fine.
Eventually the arp cache entries age out and get deleted. Usually then my server can talk to the Windows server again. I also found that if I delete both arp cache entries for the target Windows server, my server can talk to it again (arp cache gets rebuilt with the ce0 interface). If left alone, the behavior seems to be that my server can talk to a Windows target for an hour or two, then it can't for another hour or two, then the cycle repeats.
NOTE - The mac address in the arp cache is not getting poisoned, as with the Broadcom windows driver issue that hit some folks (myself included). All the mac addresses for the servers in the arp cache are consistent as best I can tell, so that's not the problem.
Any input/suggestions greatly appreciated.

Here are the codes:
In the initializing stage,
     try {
          this.serialPort = (SerialPort) portId.open("SimpleReadApp", 2000);
     } catch (PortInUseException e) {
         e.printStackTrace();
     this.serialPort.notifyOnDataAvailable(false);
     try {
        this.serialPort.setSerialPortParams(9600, SerialPort.DATABITS_8, SerialPort.STOPBITS_1, SerialPort.PARITY_NONE);
        this.serialPort.setFlowControlMode(SerialPort.FLOWCONTROL_NONE);
        this.serialPort.enableReceiveTimeout(10);
//this.serialPort.disableReceiveTimeout();
//this.serialPort.enableReceiveThreshold(0);
        this.serialPort.enableReceiveThreshold(1*1024*1024);
        if (this.serialPort.getInputStream() != null)
                this.inputStream = this.serialPort.getInputStream();
        else
                System.out.print("can not get inpustream!\n");
      } catch (Exception e) {
              e.printStackTrace();
      }Then in the reading stage, we have:
    byte[] readBuffer = new byte[1 * 1024 * 10];
    while (true) {
          try {
               int numBytes = inputStream.read(readBuffer);
               System.out.print("There are " + numBytes + " bytes having been read.");
          } catch (Exception e) {
              e.printStackTrace();
          }The above codes do not have any problem using COMM API 2.0 on Windows. Or COMM API 3.0 on Solaris. But, on RedHat, it can run out of memory very quickly.

ARP cache poisoning detection disabled

I recently checked all the messages in the console and found the following error message: Could not enable ARP cache poisoning detection. Your computer will not be protected. This message is logged every time I turn on the computer. I am assuming this problem started when I upgraded to Mac OS 10.5.6 since I have never seen this message before and it does not appear on my other machine that is still on Mac OS 10.5.5. Is anyone else getting this message?? Is there any way to resolve this issue so that my computer will be protected? Is Apple aware of this problem and is perhaps working on a fix??

ARP Cache Poison behavior by Apple TV

Norton Anti-Virus reports blocking an ARP Cache Poison attack against my home network. The reported source of the attack is the MAC number of the Apple TV on the network.
Whether Norton is "reliable" is apparently contentious in the support community. Several authors suggest, with authority, disabling Norton or the particular attack profile.
Whether that makes sense depends on what the Apple TV is innocently doing to be profiled as a network attack.
Even when supposedly "asleep" the Apple TV is doing something that meets the profile of an ARP Cache Poison attack. It did it every 30 minutes today, nine times yesterday, about 30 times day before and etc.
And if it is a design feature of the device, why is the device still performing despite having the activity continously blocked? What is the purpose of this attack-like activity, assuming it is not an attack? If it is an attack, how does one erase the programming initiating the attacks and still have an Apple TV?

Short answer: it is a false positive. I don't know exactly what causes it but I would guess Apple's Bonjour protocol, which is why you see something every 30 minutes. That's just a blind guess, but seems to fit.
Realize that a report of ARP poisoning wouldn't be likely on a private LAN, unless you got infected somehow. No known malware like this for iOS devices (and much harder to insert one on AppleTV versus an iPhone or iPad.) There are legitimate cases where ARP spoofing is used. And even Cisco has instances where they say to ignore that warning:
CSCsm25943—The meaning of the following error message on the controller is not clear. This message does not necessarily imply that any actual "ARP poisoning" is occurring. Rather, this message appears when a WLAN is configured for DHCP Required and a client (after associating to this WLAN) transmits an ARP message without first using DHCP. The client is unable to send or receive any data traffic until it performs DHCP through the controller.
DTL-1-ARP_POISON_DETECTED: STA [00:01:02:0e:54:c4, 0.0.0.0] ARP (op 1) received with
invalid SPA 192.168.1.152/TPA 192.168.0.206
Workaround: Perform the following steps:
• Verify that the client eventually does perform DHCP without undergoing an unacceptable outage. If the outage before performing DHCP is acceptable, then you can ignore this message.
I'm not saying that Norton's message is the same as Cisco's. Just that Cisco states that the meaning of why the message appears is not clear and sometimes is acceptable. And Cisco is the world leader in networking technology so if they don't always know why you get an ARP poisoning warning....
I won't go into the politics of "Norton bad" or whatever, but based on my experience (bias) with Norton in it's various forms for over 10 years, IMHO you can ignore this. Hopefully you can configure Norton to selectively ignore this. If not, you may have to use a different security program. Me personally, I do not recommend any "security suites" because they cause exactly this kind of additional headache. Just a "plain" antivirus program. Windows has a built-in firewall and most people will be using a hardware firewall at the office or home so the firewall in the "security suite" is extraneous.

Install cache error

I'm trying to install itunes 10.6 on windows 7 home premium. it downloads the software and starts to install. I receive an error: "an error occurred while attempting to create the directory c:/program data/apple/installer cache" I click retry several times and no luck so I have to click cancel and it rollsback the installation. I have downloaded a new copy of the installer from another computer and receive the same error. I dropped the UAC on the system to none. That did not work, it give me the same error. I have tried renaming the Installer Cache to a temp name and when installing again, I the error says it doesn't have the permissions to create the directory. I have gone into the control panel and attempted to repair bonjour, itunes, apple mobile device support, apple software update and quicktime and all of them have reported "The system cannot find the file specified." I have tried running the install package with the right click Run as Administrator and the install cache error still occurs. I have check the security on the file and it has my user name and full control on the parent and all items below.
When I plug in my iphone or ipod, it asks about updating to 5.1, I click download only. I then receive an error window "There was a problem downloading the software for the iphone or ipod. The network connection could not be established"
I don't know if the two problems are related. I'm at a stand still have have no other ideas of what to try next. What suggestions might you have to solve this problem?
Thanks for the help!
Joel

I tried to rename the apple computer folder to _old and I received another error with another really funky folder name that looked like a SID. I renamed that and reran.
Crikey. Probably that number (in the folder name) was the SQUID ("squished GUID") for the iTunes installation (or possibly one of the other associated components being installed). In addition to the error 5, that brings us to a total of three of the more exotic things that could possibly happen in this sort of file-access-problem context.
So, excellent work on your part getting past all that. Many thanks for reporting back with your resolution, too.

Cache error message in Adobe Bridge CS6

I am continuing to get a cache error message despite purging the cache several time on different occassion via the Preferences. Adobe Bridge now seems to be frozen on Building Criteria. The platform I am using iMac OSX 10.8.5. I have rebooted the machine a couple of times to no avail. Any advice

If Windows, search your event viewer for something like "The device \Device\Ide\iaStore0 did not respond within the timeout period." Since this
is kind of a hardware issue, there might be a similar thing happening on MACs. If you see this warning check what driver you are using for Intel
Rapid Storage Technology. I was using version 10.x and the latest from Intel is 12.x. Intel cautions you not to use this updated driver without
checking with the system manufacturer, which in my case, Asus, maintained that 10.x was the latest approved driver. I installed the 12.x driver
directly from Intel despite the warning, and the problem seems to have been resolved. I post in case this gives someone else a clue to solve
this nagging problem.
Oh, this might be particularly significant if you have recently installed a larger hard disk.

URGENT Bridge and cache error photo corrupted NEED HELP

We were going to edit a photo and upon opening it and error came up and said: "edit bridge encountered a problem and is unable to read the cache. please try purging the central cache in cache peferences to correct situation"
We solved the cache problem by purging it but the photo is corrupted! Furthermore, the photo turned red and 1/3 of the photo has been mysteriously turned black! It only briefly returns to normal after cache problem in adobe bridge. It turns normal but only for a split second!!! WE NEED THIS PHOTO RESTORED TO ORIGINAL CONDITION BEFORE THE CACHE ERROR.
Thank you for help

Your photo may be lost, I'm sorry to say.
Check your Windows System Event log and look for disk errors. Disks do fail, and if there have been unrecoverable errors you'll see them in the event log.
A failing disk is not something to be left alone. I hope you have a recent backup - if not, make one right away, then replace any failing disk drive ASAP, or you chance losing more data. I always recommend high-reliability enterprise class disk drives such as Western Digital RE4. They're not that much more expensive, and lost data can be worth a lot.

Force mapping to a specific MAC address a multicast IP address in ARP cache table with netsh

Hi all,
I would like to know if there is any solution (netsh option, registry entry, whatever...) to force mapping a given MAC address to a multicast IP address (224.x.y.z) in my ARP cache table.
I am doing the following:
netsh.exe interface ip add neighbors "Ethernet" "224.224.xxx.yyy"
"00-80-EE-UU-VV-WW"
But the entry in the ARP table is substitued by the calculated multicast MAC@ corresponding to my multicast IP@ :
netsh.exe interface ip show neighbors "Ethernet"
Interface 12 : Ethernet
Internet Address
Physical Address Type
224.0.0.22
01-00-5e-XX-YY-ZZ
static
224.224.yyy.zzz
01-00-5e-UU-VV-WW
static
(For information, calculation of the Multicast MAC Address is described in RFC1112§6.4 -> The MAC@ equals 01-00-5e + the last 23 digits of the multicast MAC Address)
My problem is that I'm not using an Ethernet network but an AFDX (used on Airbus A380, Boeing 787 Dreamliner, by the NASA...). This network topology is a deterministic Ethernet. The network must know accurately where each network packet is going. Thus...
the multicast MAC@ cannot be accepted and packet destinated to that MAC@ are not going anywhere.
So, I must match accurately my multicast IP@ to my MAC@ (00-80...).
It used to work with Windows XP (which was not doing any "magical" MAC@ substitution on multicast IP@), but since Windows Vista, netsh is doing the substitution described above. Is there any way to disable this substitution or force my IP
to MAC mapping in ARP table? And of course, I'm not using XP anymore ;)... but a tablet with Windows 8.1.
Thanks for any help.
Cheers,
Olivier.

Hi,
The article you pointed me to is just an explanation of what I said in my original post : "Multicast MAC Address is described in RFC1112§6.4".
But, as I said in my original post, this is true ONLY for Ethernet network. And I am NOT on an Ethernet network.
So MAC address automatic calculation for my IP address done by Windows/netsh/arp is wrong in my case. The calculation Windows is doing is correct ONLY for Ethernet network. Since I am not on Ethernet, I don't want these calculations, and I'm looking for
a solution to disable them.
So, the underlying question is : "Is Microsoft/netsh/arp able to handle other network's type than Ethernet ?"
Thanks,
Olivier Dupré.

Firefox 5 seems to cache error redirects.

Firefox 5 seems to cache error redirects.If for example I get redirected to a 404 then fix the problem with the site, it will still redirect me to the 404.

Try to Reload web page(s) and bypass the cache.

Clear arp-cache to ping

I have an SMS server on my network that is unreachable from vlans other that its own. This happened after we pushed out tumbleweed via SMS. Now, in order to ping the server I must issue a clear arp-cache in the core switch, this only last for about 1 min and then the SMS server is unreachable again. Any help would be great.

Thanks Dabels,
I have had this problem as well, it turned out to be a pix.
Proxy-arp is enabled by default on all interfaces and its not apparent in the config when its on or off. Its configured as a sysopt and therefore, it often gets overlooked.
Agree with everything you say, check the mac in the arp table of the server when your pings are failing, then trace the MAC you find there which corresponds to the ip address of the router.
Or check the arp entry in the router (again when its failing) and verify the MAC is the SMS server, it may just turn out to be a router or a pix or even....another server which is routing between a pair of NIC's, such as a unix box or a windows server.
Let us know how you get on.
Cheers
Shaun

What is a ARP cache and how do I clear this cache?

Each time I try to repair my internet connection it states, "unable to complete the repair because it was unable to clear the ARP cache. I do not know or am unable to find in any help file where or what this cache is. Assistance with this would be appreciated greatly. thank you

Hello Abubaker,
It crashed due to a parity error.
Imprecise Data Parity Error
Imprecise Data Parity Error
Which in other words means, a temporary error in memory. On single occurence adivice is to monitor the supervisor for re-occurence of such failure again. You can monitor it for 24 - 48 hours and if its a hard failure , the likelyhood of issue coming again is more and you need to replace supervisor. If it does not repeat you can consider this as a one time issue and contnue using it.
Hope this helps and please always rate useful posts.
Thanks,
Madhu

How do you troubleshoot Caching Errors in Java Runtime Environment?

I have run into Caching Errors while using JRE (versions 1.4.2 and 1.5.0, various updates) using Windows XP and IE6. The error screen has the title Error - Cache and appears when trying to download JAR files through a secure HTTP connection. The error reads: "Caching Error. Unable to store or update files in the cache." In the details box, the first line can differ:
java.net.SocketException: Connection reset
java.net.UnknownHostException: [followed by a URL]
java.net.ConnectException: Connection timed out: connect
I looked in the Java Control Panel to make sure that the "Enable caching" box is checked, and removed the proxy settings in IE. The user has sufficient rights on the computer to download files.
How does one go about troubleshooting these caching errors? Is there a reference document available? I could not find anything on the Sun site or anywhere else.
Any help would be very much appreciated.

I deleted c:\Documents and Settings\<user>\Application Data\Sun (the same as in Java Control Panel->Temporary Internet Files->Settings, but at higher level). After that and some machine reboots it worked.
