Multiple Console Connections

I just ordered used switches and routers from eBay and I was wondering was thier a way to have each device with a console cable somehow connected to my computer? I heard having a console to serial then serial to usb on a hub would work, any feed back on this method?

Multiple USB-to-serial connections can work. But that really doesn't look good ... ;-)
In addition to Paolos suggested 2511, you could use a very cheap 3620 or 2600 router with an NM-16A. With this module you also need an octal-cable to connect the console-ports.

Multiple vnc console connections for guest vm

Is there anyway to allow multiple computers to connect to the same guest VNC console?
I noticed in the vm.cfg there were multiple VNC options and I attempted to play with them to see if I could get multiple console connections to work. After editing the file and restarting the guest vm I couldn't get multiple connections. The VM Server users guide didn't provide any clarity on what the VNC commands in the vm.cfg do, just some examples of guest configs. Can anyone enlighten me on how to do this or possibly refer to a link if this question has been asked in the past.
Thanks,
nathan

Q1:Is there anyway to allow multiple computers to connect to the same guest VNC console?
I suggest that you config/start vnc server on guest OS, and you may connect it from different computers. it make sense for you?
Q2:Can anyone enlighten me on how to do this or possibly refer to a link if this question has been asked in the past.
Pleaser refer to this link to know more about VNC options in vm.cfg.

App Controller 2012 R2, cannot open multiple console windows at the same time

Hi All
I have just moved from SCVMM 2012 SP1 and AppController 2012 SP1 to the 2012 R2 versions. In the previous version my users were able login to app controller, select the virtual machine that they wanted to connect to and click on the console button (or right
click and select console) and this would open in a new tab in IE, they could do this for multiple VM's and could have multiple tabs in IE so that they could switch between them easily.
However, since the upgrade, they can now open only one console tab. each time they click on a new VM and select console, it will open in the same IE tab. Meaning that switching between console sessions on multiple machines has become a lot harder.
I've checked all the obvious IE options, and multiple machines/users, so this seems to be a setting in Silverlight or in IIS somewhere that has changed. I've had a good search around (bing/google) but can't find anything. Has anyone got any suggestions
on how we can get back to the old multiple consoles in there own tab scenario?
Cheers
Darren

Hi Arne411,
Thank you for sharing the frustration you're experiencing due to this bug.
There are a few options:
If you have Premier support you can open a support case and make a Request for Hotfix (RFH). If an RFH is accepted then you may get the fix prior to its public release. This process also helps us to better understand the issue, number of people affected
and can increase the priority of producing a fix.
Provide users access to the VMM Administrator Console. As a member of the Application Administrator (Self-service user) role they will have the same capabilities for accessing VMM managed VMs that they do with App Controller.
Consider moving to the Windows Azure Pack as the web portal. This has the benefit of being HTML based and provides console access through the RDP client.
Kind Regards
Richard

Establishing multiple WLEC connection pools

Running WLS 6.0 communicating with WLE 4.2:
I'm looking at setting up multiple connection pools to communicate with multiple
WLE application domains.
The code fragment below is from the BEA documentation and works fine if you know
the domain(pool) name. My code uses the "lookup" method in the InitialContext
class to get the pool name for single WLEC pool/domain configuration. Is there
a method to return a list of domain(pool) names?
Each WLEC connection pool has a Tobj_Bootstrap object that lets you access the
associated WLE domain. The WLEC component provides an object called BootstrapFactory
which provides access to the Tobj_Bootstrap object for a particular WLE domain.
Include the following code in your WebLogic Server client to connect to a WLE
domain:
Tobj_Bootstrap myBootstrap = Tobj_BootstrapFactory.getClientContext("myPool");
where
The getClientContext() method returns the Tobj_Bootstrap object that is associated
with myPool. If getClientContext() cannot find a WLEC connection pool with this
name, it returns null.
myPool is the name of a WLEC connection pool for the desired WLE domain. This
WLEC connection pool needs to be defined in the Administration Console.

Well ... It boiled down to ACLs.

Is there a risk of setting a console connection timeout and what is the recommended setting?

Is there a risk of setting a console connection timeout and what is the recommended setting? Please suggest if there is any best prctice documentation that can be referred.

Hi Henrik
depend on what you need or what your security policy says for my lab gear i use 60 minutes. because i know how can access this. if you have gear outside in insecure space set it to a minimum or disable the console. everybody how can access your gear can break in. simple restart and boot w/o config. and you are in.
it realy depends how secure is your space and how much security you need.
and than the settings for policy have to match, what sec do you have if your console login and logout is secure. but when you restart you can simple break in by starting w/o config and than load it.

Our home network has multiple devices connected by iCloud. Having problem with Calendar. On one iMac, all the events are duplicated. How can I correct that problem? Under the Calendar accounts, I had my Apple id listed and also just iCloud.

Our home network has multiple devices connected by iCloud: 2 iMacs, 2 iPhone 4s, 1 MacPro Laptop, and 1 iPad 2. When using Calendar, all the events were
duplicated on my husbands iMac. On his computer, under Calendar accounts, I had included iCloud and also my iCloud ID. I thought that because I had two accounts listed that were connected to iCloud, that might be the cause of the duplication. When I deleted ithe calendars from one of the accounts, it resulted
in deleting all of the events on all of our network devices!
I have since entered some new events into Calendar from my iMac and from my iPhone. These appear correctly on all devices except my husband's iMac where they are again all duplicated.
I have two questions: 1) How can I eliminate the duplicated events on my husband's computer and 2) How do I retrieve the old wiped out Calendar events from
Time Capsule. I don't know how to find Calendar in the Time Capsule. If I find the Calendar information in Time Capsule, how do I transfer it to my current Calendars?
I was obtaining phone help from one of the Apple techs at Apple Support, but our call was disconnected part way through. Didn't know how to reconnect with the tech.
Thanks for any help.

How to provide access to multiple users connected to a Dumb switch? (multi-auth/multi-domain)

Good morning everybody,
I am writing on behalf of not being able to implement a desired outcome in our company network. In fact the situation is as follows:
What I want to do is to be able to authenticate users (802.1x authentication) in our company radius server and authorize them access by having a dynamic VLAN assignment in a multi-user environment on one and the same port of a Cisco 2960 switch. So far, the authentication and authorization has been working completely smoothly (there are no problems with itself). The concept involves the configuration of both DATA and VOICE VLANs as I there is also phone authentication implemented. In order to simulate this environment I introduce a Dumb switch connected to my Cisco 2960 Catalyst.
What I have successfully managed to get to work so far is this:
1) On one switch port I have tried the “authentication host-mode multi-domain” and it worked perfectly for a PC behind a telephone, or with one PC connected to a the dumb switch + the telephone connected to another port of the dumb switch. Logically it is the same situation as there is a separation in two domains – DATA and VOICE. Bellow is an output from show authentication sessions for this scenario.
Interface MAC Address Method Domain Status Session ID
Fa0/23 0021.9b62.b79b dot1x DATA Authz Success C0A8FF69000000F3008E (user1)
Fa0/23 0015.655c.b912 dot1x VOICE Authz Success C0A8FF69000000F9009F (phone)
2) On the other hand, when I try the same scenario with the “authentication host-mode multi-auth”, the switch still separates the traffic in two domains and is able to authenticate all users, AS LONG AS they are in the same VLAN.
show authentication sessions:
Interface MAC Address Method Domain Status Session ID
Fa0/23 0021.9b62.b79b dot1x DATA Authz Success C0A8FF69000000F3008E (user1)
Fa0/23 b888.e3eb.ebac dot1x DATA Authz Success C0A8FF69000000F8008C (user2)
Fa0/23 0015.655c.b912 dot1x VOICE Authz Success C0A8FF69000000F9009F (phone)
However, I cannot succeed authentication of many users from DIFFERENT VLANs, neither in multi-auth nor in multi-domain modes.
What I want to get is an output like this:
Interface MAC Address Method Domain Status Session ID
Fa0/23 0021.9b62.b79b dot1x DATA Authz Success C0A8FF69000000F3008E (user1)
Fa0/23 b888.e3eb.ebac dot1x DATA Authz Success C0A8FF69000000F8008C (user2)
Fa0/23 0015.655c.b912 dot1x VOICE Authz Success C0A8FF69000000F9009F (phone)
I want the switch to authenticate the users anytime they connect to itself and for them to have an instant access to the network. (I tell this because I tried scenario 1) with multi-domain mode and authentication violation replace, and it worked but, two users never had access to the “Internet” simultaneously!!!
The configuration of the interface connected to the Dumb switch is as follows.
interface FastEthernet0/x
description Connection to DUMBswitch
switchport mode access
switchport voice vlan XXX
switchport port-security maximum 10
switchport port-security
switchport port-security violation protect
authentication host-mode multi-auth
authentication priority dot1x
authentication port-control auto
authentication timer reauthenticate 4000
authentication violation replace
dot1x pae authenticator
dot1x timeout tx-period 10
spanning-tree portfast
The way I see it is explained in the following steps:
- PC1 connects to the Dumb switch. This causes the Cisco switch to authenticate user1. This creates an auth. session with its MAC address linked to a domain DATA.
- When PC2 connects to the Dumb switch, this causes the violation replace which replaces the recent authenticated MAC address with the MAC of PC2. I would like it once authenticated to appear in the authentication sessions with a link to a new DATA domain linked to the VLAN assigned from the RADIUS server.
Is this possible? I think (in theory) this is the only way to provide authenticated access to multiple users connecting through Dumb switch to the network.
Has anybody ever succeeded in such a configuration example and if yes, I would be love to get some help in doing so?
Thank you
Stoimen Hristov

Hi Stoimen,
I have done a setup similar to yours with the only exception being VLAN assignment. When I used dACLs only, it makes things somewhat easier as the VLAN no longer matters. Remember that the switchport is in access mode and will only allow a single VLAN across it (with the exception of the voice VLAN). I think that is the real cause of your problem.
From what I can see, you have 2 options available to you:
1) Use dACLs instead of VLAN assignment. This means that an access list will be downloaded from the radius server straight to the authenticated user's session. I have tested this and it works perfectly. Just Google Cisco IBNS quick reference guide and look for the section that deals with Low Impact mode.
2) Get rid of the dumb switches and use managed switches throughout your network. Dumb switches will always be a point of weakness in your network because they have no intelligence to do advanced security features like port security, 802.1x, DHCP snooping, etc.
Hopefully someone else will chime in with another option.

Problem about financial reporting studio(assign multiple db connection)

Hi,
I need to assign multiple database connections to a grid in Oracle Hyperion Financial Reporting Studio
To do this, I performed the following steps:
- Open a report.
- In a grid, select one column for which I want to change the database connection.
- In the Column Properties sheet, click the Select Database Connection button, .
- In the Select a Database Connection dialog box, select a database connection from the Database Connection drop-down list, then Click OK.
- In the Map Dimensions Between... dialog box, map dimensions between the default database connection and the selected database connection. I do this by selecting a dimension from the pull-down list in the right column for each dimension in the left column.
- Optional: Select an alias table for the new database connection.
- Click OK.
But after last step I have received next error:
*; nested exception is:*
java.lang.NullPointerException
Can someone explain the source of this error?
And help me please solve this problem because I didn’t receive figures in that column where I changed database connection.
Thank you in advance!

I'm sure that both DB connections has the same dimension hierarchy. I can open the repot, but in it I don't see figures in that column where I've changed database connection...

Does Airport Express support multiple ethernet connections via a switch?

If I use the following configuration, with the Airport Express extending my network, will it handle multiple devices connected via a switch?
Modem---Airport Extreme- - -802.11n- - -Airport Express---Switch---multiple devices (eg. network printer and iMac).
Or do I need to use a second Airport Extreme instead?

It works for me—even when the AirPort Express device is configured to extend the wireless network created by the AirPort Extreme router.

Multiple IDLE connections

Hi,
I have two IDLE enabled IMAP accounts and I'm trying to work out if everything is working properly as it doesn't feel like it is.
When I check netstat it shows multiple established connections for each account which seems to many for it to be right.
Any thoughts on what to check? Server is showing two connections which would be right.
Thanks,
Adam

If you must have a 1-1 app user/connection to database user/connection, then using a DatabaseSession would probably be the easiest solution. The means that each user would create and connect to their own DatabaseSession when they login to the app. You could still share the same TopLink project instance to reduce some of the connecting/initialization overhead, but there would be no way to pool connections. Using a DatabaseSession would not allow for any shared caching across users.
Do you need to be connected as the user for reading, or just for writing to the database? If you can use a shared user/connection for reading, then you could use a ServerSession and have a shared cache. Define the shared user in the ServerSession, and when each user connects acquire a ClientSession through the acquireClientSession(DatabaseLogin) API, which allows you to specify the user/password to connect as for writing.
In TopLink 10.1.3 you may also wish to investigate the VPD and exclusive client connection support. This allows for some of your data to be read through a user/VPD secure connection, and other shared data to still be cached. It also allows for the user/VPD to be switched on a pooled connection.

Multiple WLAN connections

Does anyone know of a way to get my PODCAST and Email applications to use multiple WLAN connections?
I spend most of my day in one of two places, each with a different WLAN, and I'd the phone to have the sense to change WLAN connection as they become available.
Thanks for your time.

Depends, on what your phone is.
If you're using an N97 or a 5800, or anything running on s60v5 for that matter, Go to Menu>Settings>Connectivity>Wireless LAN>Options>Settings>Show WLAN availability. Then you can also set how often it will set to scan for WLAN connections. This would allow the phone to scan for WLAN hotspots around you immediately. Be warned however that this will drain your battery faster.
On an s60v3 phone, I am not very familiar but from what I know its in Menu>Tools>Connectivity>Wireless LAN>Options>Settings>Show WLAn availability.

Multiple AWS connections

Hi all,
Can MCAK handle multiple AWS connections in current version?
If not, if there is a plan let me know.
My customer would like to use multiple AWS regions (e.g. US-East and Tokyo) because of BCP/DR.
thanks,
Jun Kojima

Yes, Multi-Cloud is designed to support multiple connections across the same or multiple platforms. You can even have multiple connections to the same AWS region using different accounts to facilitate chargeback allocation. You also have the option to specify and availability zone.
PS. A new version of the Multi-Cloud kit will be available late February along with CIAC Enterprise Edition 3.1.1 offering full future upgradeability. For AWS, it will also support elastic IP and the management and distribution of keypairs.The current MCAK for Starter Edition is recommended for proof of concept only at this point.

Bluetooth Serial and Cisco Console connections?

This may be the wrong forum for this, but network management was the closest fit i could find...
(First off, I agree that console connections are not preferred, SSH, HTTPS, SNMP all have their advantages, but when something goes down or stops responding to normal methods the amount of time and frustration that can be saved by not having to search for "that one laptop that has a serial port" or "my specific laptop that has the USB-Serial driver installed" is invaluable.)
With the proliferation of tablet devices (ipad, cius, samsung's proposed, etc.), add to it a serious lack of serial ports on most laptops/netbooks/etc being released. It's getting harder and harder to connect to console ports on cisco devices. USB to serial adapters fit the bill for now, provided you had the right drivers to run the adapter on your device (read: doesn't address tablets and smartphones).
I understand that the cisco console connection is considered "legacy" and that USB connections are becoming more popular with newer Cisco devices, but in the meantime it would be nice to manage my slice of the millions of "legacy" devices out there.
Bluetooth serial seems to hold promise, though the serial features of bluetooth aren't typically incorporated into most devices right now. What i guess I'm looking for is a way to manage my router and switch console ports from a smart phone or tablet device.
Has anyone seen anything like this out there right now?
I would think that Cisco would be interested in marketing such a feature with their new Cius, or an iPod or Android app. Even if it cost a couple of bucks for the adapter or the software, it would be well worth it to be able manage these devices in a pinch.
Thanks to anyone that can help!
JM

I agree, it wold be handy to have.
One thing some of us use is iSSH on the iPhone or iPad. Straight across the in-house wi-fi LAN if there's a working one in house or via the VPN tunnel if not. The use cases of no w-fi, no VPN or an unresponsive box are still not addressed by that solution though.
