Dell N Series Switch Port Mirror

Need to Monitor some Traffic with Wire shark?

First, set the port you are sending the traffic to have no config

Then setup the configuration:

monitor session 1 source vlan 25 rx
monitor session 1 destination interface Gi1/0/10
monitor session 1 mode

NOTE: The last line enables the monitor session, you can disable it by using the No command in front

iDRAC Java connection error – work around for old iDRAC versions (6,7,8)

The issue is unsupported algorithms by the iDRAC system. iDRAC6 still has yet to fix this (9/3/2018) but is resolved on 7+ AFAIK

There is only a single item to remove from your java.security file to retain the IDRAC6 functionality.

jdk.tls.disabledAlgorithms=SSLv3, RC4, MD5withRSA, DH keySize < 1024, \
    EC keySize < 224, DES40_CBC, RC4_40, 3DES_EDE_CBC

need to be changed to

jdk.tls.disabledAlgorithms=SSLv3, RC4, MD5withRSA, DH keySize < 1024, \
    EC keySize < 224, DES40_CBC, RC4_40

Effectively it’s only `3DES_EDE_CBC` instance should be removed from this directive and nothing more.

Additionally i would reccommend you make the following change in the IDRAC
webpage:
iDRAC Settings –> Network/Security –> Services: Change the SSL
Encryption to 256-bit or higher.
This doesn’t negate the above change thats needed in your java.security
file until Dell makes a Fix.

Reinstall Appassure Agent on Linux

If you don’t backup the agent config file, you will get a new Identity and won’t be able to align the backups back up with the same protected system.

to back it up:
cp -p /root/.mono/registry/CurrentUser/software/apprecovery/agent/agentid/values.xml ~/values-backup.xml

Uninstall the old agent, Reboot
Install the new agent, Reboot

Then Restore the file

mv ~/values-backup.xml /root/.mono/registry/CurrentUser/software/apprecovery/agent/agentid/values.xml

restart the appassure-agent service

You should be good to go.

install Dell Server Admin on ESXi5

http://www.journeyofthegeek.com/?p=204

 

All right folks, I’ve decided to save you hours of time once again and provide a comprehensive guide to installing the Dell OpenManage Server Administrator (OMSA) client on ESXi 5. I pieced this together from a variety of user guides and forum posts and have tested it on an ESXi 5 box I use for labs. Instructions are as follows:

  1. Download the latest version of “Dell OpenManage Offline Bundle and VIB for ESXi”. The easiest way to find it is to go to the Dell Support homepage. Select the model of the Dell server you are working with, filter the operating system to your version of ESXi, expand the System Management section, and do a search for “offline bundle”. Once you download the file, rename it to something simple like omsa.zip. This will make your life easier during the later steps where you will be typing out the file path and filename.

Your system homepage is now availible via https://hostname:1311, where hostname is the hostname of your server.

yum install $(bootstrap_firmware)

Now run either inventory_firmware or inventory_firmware_gui to view your firmware versions, and perform firmware upgrades.
