inaccurate NSDB desc for GIS 2001 # ICMP Host Unreachable
GIS # 2001 fires when there are ICMP type 3 sachets. This type of message is more correctly described as inaccessible Destination (refer to IANA).
Triggers of signature on all type 3 messages, but to be precise in the description of the NSDB, it should trigger only on Type 3 Code 1 (refer to IANA).
Can Cisco please make corrections of the NSDB for S94, or correct the signature to only shoot ICMP Type 3 Code 1. I can adjust the setting of code through IDM, but it gets reset after the deployment of config IDS MC. Very annoying (see my previous post) to correctly set up sigs by IDM having to do again after MC IDS push.
http://www.IANA.org/assignments/ICMP-parameters
A fix has been implemented with S94. CSCee64472 following the issue. The NSDB has been updated to reflect the addition of the 1 ICMP code.

Default time for IDM to block hosts
In ID 4.0, what is the default time for IDM to block hosts (in the access list for a router)? And this time is configurable?
Sensor CLI:
end of config
Service configuration-sensor-virtual virtualSensor
Melody
shunEvent
ShunTime (minutes block guests)
Of IDM:
Click on Configuration
Click on block
Click blocking properties
Update the blocking time input control.
Note: This was recently added to the IDM, so you may need
upgrade to the latest version of the IDS software.

Why can't I configure the POP/IMAP mails for my Muse site in Business Catalyst? I don't have the option "use this service for e-mail as hosting the Web site" under Advanced options.
Is this due to my hosting Plan? Appreciate the answers.
Your site is a CCM that is located on a WebBasics plan (this plan does not e-mail hosted on Business Catalyst).
If you want to create the email addresses on this site, you will need to configure your mail elsewhere server and configure the MX records on your site to point to the external mail server.
If you want to use the hosted Business catalyst e-mail services, you should use a WebBasics + or superior siteplan. To upgrade your free CCM site, access administration area of your site-> Site Management-> upgrade now-> choose the desired site plan and billing frequency-> Add personal and credit card details-> Submit.
Please see this article on setting up email on your site of BC accounts: http://docs.businesscatalyst.com/user-manual#! / settings/mail electronic-users of the site -
For the establishment of the records point to the external mail server, see http://docs.businesscatalyst.com/user-manual#! / settings/email-users/creation-boxes of reception-for-your-users of the site

Need to publish for a 3rd party host of Muse.
I tried to post my Muse site for a 3rd party host with no luck. It seems that the 2 options that I have met so far that I can use Adobe accommodation or export to HTML format and then download via Dreamweaver (which no longer works). Does anyone know how to get around this problem so that I can use outside the accommodation?
Thank you!!
Hello
The message indicates that you are trying to use the webforms in Muse widget and it seems that your host does not support PHP or PHP mail service.
Please see the document: http://forums.adobe.com/docs/DOC-3581 and contact your hosting provider in this regard.
Kind regards

If someone can clarify that the exception java.net.PortUnreachableException: ICMP Port Unreachable shows (outside of what is obvious)? Here's the scenario: using UDP I a client application, a portal application and a server application. The client sends to the server through the gateway and vice versa. I created 2 Sockets, a conflict between the client and the gateway and the other between the gateway and the server. When I try to send from the bridge to the client package never makes it to the client (server-side is fine). When I call sock.getLocalSocketAddress and sock.getRemoteSocketAddress are all two 0.0.0.0 (the latter has at least the right port number). The gateway acts as a server for the customer and as a client to the server. I tried to solve this problem using sock.connect on the side of the gateway for the client in the face of the plug, but it has ultimately generates inaccessible except for ICMP port on the side of the door of entry upon receipt by the customer.
Thank you in advance.This means that there is no UDP connectivity between whatever the host gets the exception and regardless of the host this socket is connected to. Usually a firewall issue.
The address 0.0.0.0 means only that the socket is bound to all interfaces, this isn't a problem.

E.M.P. 11.1.2.2 configurator - host unreachable
Hi John,.
I have read the below article posted by you and I get the same error "the next guests are inaccessible." given that the environment is protected firewall. I would like to get confirmed if I can't ignore this warning or should I activate the ICMP protocol to avoid any problems.
http://John-Goodwin.blogspot.com/2013/01/EPM-11122-Configurator-host-unreachable.htmlYes, you can ignore the warning, if you cannot connect to the shared services database then that is a different matter but everything connects and then the warning is not a problem.
See you soon

12543 AMT Destination Host Unreachable
Hello
I'm accessing Oracle DB on Linux (it is installed in a VM) get the following error.

If anyone can help?
I would like to access Oracle DB and take a full backup of this one...
Any help is appreciated...

So, today I received my new 9320 at Virgin Mobile, first Blackberry & love the phone! but I can't use the BBM or Facebook app...
At first I could not even access the browser while that connected to my wifi... then I phoned Virgin & they helped me to reset the settings on my BB that I could use the browser etc...
I thought it was problem solved, until I discovered BBM and Facebook, use app world separate service? Anyway, I phoned up to Virgin because I wanted to do this job, they are included in my package & I did not understand why I can't access any of them...
After a long phone call the problem has proved that the "host routing table" was empty and (according to in Virgin) there is a problem with new BlackBerry receiving these details... they said this isn't a problem on the end there & told me there is nothing more they can do so to click 'register now' and wait for the details...
24 hours later and nothing, so I hope someone here can help me, make me a BB the whole point is things miss me actually lol and I feel now I'm paying for a phone contract I can't really use it, without any help from my provider?
Any help?
Or
Anyone with a new BB knows something like that recently? Thank you
Wow... Virgin you gave really there. You see, you PAY for 100% of your services and 100% of your formal support... at the moment, they seem to be or you deliver. Only they have the ability (in fact the RESPONSIBILITY!) to degenerate RIM requiring improved support of cases (from your description, it must be that... with a HRT empty, nothing that anyone here can do). End users have no free path to receive assistance from the RIM at all - only via the escalation. So, what I would do if I were you, is their ring back... but this time do not let you fob OFF... insist that, because you HAVE them, you have a contract with them and they are about to be in violation of this contract - they must solve your problem, degenerate into RIM if they wish.
Good luck!

Remove data for a downgraded ESXi host syslog collector?
Hello
We already put out of service an ESXi 5 host in the cluster.
However, network Syslog Collector, the host still appears with the hostname / IP address and the size of the log (about 18 MB).
We would like to seek your advice on how to remove this entry to ESXi host Syslog collector Page. Should I restart the service "VMware vSphere Syslog Collector" on vCenter Server?
Thank you
Post edited by: TonyJK
If the server esxi already downgraded in judgment of sate, then you can delete the syslog file (in vcenter) to as esxi. If the underwater ESXI still running, you can disable forewall port for syslog (even if you can remove the host name of the syslog setting advanced collector.)
