• SSH keys no longer work after macOS Sierra Update

  Hello, I have a problem to connect my servers with my previously stored private ssh key in file .ssh with terminal commands or third-party applications. I should mention that I activated the filevault during the upgrade process. I see that my passphases are stored in the keychain, but I need to enter my password every time I want to connect to servers.

  Hello Marshall,

  Try to create a new ssh key. I think Sierra includes updated logic crypto and he doesn't like really old keys.

• Import a public ssh key for a specific user of DRAC via racadm?

  Is there a racadm command to download and install a public ssh key into account a specific drac of the user.

  In the GUI, I see features to add 4 different keys per user access from remote devices with the key private without a password for ssh.

  I have not found a command for it in the last iDRAC CLI PDF 7/8.

  I don't see that installed public keys are exported with an export of the server profile which would mean that access would be lost when profile importing. Is this correct? If so is this remedied the iDRAC future releases?

  You can use "racadm sshpkauth" to import or delete the public SSH key users to iDRAC.  You can get more details on the use of race using command "racadm help sshpkauth" or the RACADM CLI guide (link below)

  http://www.Dell.com/support/manuals/us/en/19/idrac7-8-lifecycle-controller-v2.30.30.30/iDRAC_RACADM_Pub/sshpkauth?GUID=GUID-BE12ABD1-4995-4FA3-B090-9CB41321B7A4&lang=en-us

• generation SSH key

  I use a 506th PIX.  I already have some ssh addresses, but I need to add a new ssh address.  Do I need to generate a new key or should I use the existing key?  In addition, if there is already a key genereated must cleared and a new generated when new ssh addresses are added?

  If you add more IPS that are allowed to connect to the pix using ssh, then you do not generate a new key. The existing ssh key will be used.

• Authorized SSH Keys

  I try to configure authentication using SSH on my ID I authorized keys generated my pair of keys using Puttygen.

  When I go in configure my key allowed, I can't determine what my Public Exponent is supposed to be. Anyone can shed some light?

  Thank you

  PuTTY has been my favorite client SSH for nearly four years.

  I am currently using a recent version of PuTTY (2 July 2004), and the following instructions have been written for this new version. However, build everything from a snapshot taken in recent years should work.

  The main problem in establishing authorized SSH keys is that only the oldest RSA1 key format is acceptable. This means that you must indicate your key generator to create a RSA1 key, and you need to restrict the SSH client using the SSH1 protocol.

  Here is how you do it with recent versions of PuTTY:

  (1) launch puttygen

  (2) in the group 'Settings' at the bottom of the dialog box, click the type of key SSH1. Also, I would recommend to set the number of bits in the key generated to 2048.

  3) click on Generate... Follow the instructions. The key information appears in the upper pane of the dialog box.

  (4) clear on the 'key' comment editing area

  (5) to select all the text in the pane labeled "Public key for pasting into authorized_keys file" and press Ctrl-C.

  (6) areas of edition of type a password in the "Key passphrase" and "Confirm passphrase".

  7) click "save private key".

  (8) save the PuTTY private key file to a directory that is private to your Windows login (in the "Documents and Settings / (userid) /My Documents" subtree under Win2K/XP).

  (9) launch PuTTY

  (10) create a new PuTTY session as follows:

  Session:

  IP address: IP address of the sensor IDS

  Protocol: SSH

  Port: 22

  Connection:

  Auto-login username: cisco (or whatever connection you use on the sensor)

  Connection/SSH:

  Preferred SSH version: 1 only

  Connection/SSH/Auth:

  Private key for authentication file: Navigate to the. PPK file saved in step 8 above.

  Session: (back to top)

  Saved sessions: (enter the sensor name, click Save)

  11) click Open

  Use password authentication to connect to the sensor CLI, since we do not yet have the public key on the sensor.

  (12) type the following command in CLI and press ENTER:

  Configure the terminal

  (13) the following command in the CLI, but do not press ENTER again (make and type a space at the end):

  SSH authorized key mykey

  (14) right click of the mouse in the PuTTY terminal window... causing material Clipboard copied in step 5 to be entered in the CLI

  (15) press on enter

  (16) type the following command in CLI and press ENTER:

  output

  (17) confirm that the authorized key has been entered correctly. The following CLI command and press ENTER:

  view authorized ssh keys mykey

  (18) leave the CLI IDS. The following CLI command and press ENTER:

• VMWare ESXi 3.5U4 - reboot remove SSH Keys

  Hi all

  I have a server ESXi I'm SSH'ing to. I have generated a public/private key pair. I know it is not supported... but I have a need to do so. I followed the instructions on the creation of the server's .ssh directory and put the keys in there.

  Unfortunately, it seems that, after a restart (initiated through the VI Client), the keys were gone, so that any file that was not part of the original installation. I guess is the expected behavior. But, how is it possible solution so that I can continue to connect to the server without password?

  Thank you!

• Firmware 1.2.7.76 crash and the loss of the ssh keys SG-300

  Hello

  2 of our 7 switches SG-300-52 updated new firmware now.

  Our preliminary findings:

  -(boring): switch regenerates it of ssh host key on every reboot. If I export the configuration, the keys can be seen, but they are

  apparently not stored and are regenerated each time the switch restarts.

  -(critical): by chance, we connected a port that was part of a port configured without lacp channel (channel-group mode 1) to a nx7k

  the port configured for the lacp Protocol. At this stage the SG-300 stops responding completely, even for the network regarding the serial console. With both sides

  properly configured for lacp, all right.

  The Ruedigerl, the critical part of your post is expected behavior when you connect to a configuration of channel-group incompatibility. Covering tree essentially denounces the switch that requires a reboot. This is true in all switches, including the catalyst series, spanning tree will make a loop and making unpleasant problems.

• SSH keys are protected by a password that is supported for SSH tunnels?

  Using SQL Developer 4.1 I get an error if I try to connect a SSH Tunnel using a private key that is protected by a password.

  I don't see anywhere to enter the password; is it supported?

  Thank you.

  As Jeff said, pass phrases are supported. While your keyfile may require a password, is not what we shifted upward.

  Instead, the problem is that the developer SQL does not support aes256-cbc. We don't specify as an algorithm of encryption supported by trying to open the SSH connection. If the key cannot be used. It is a bug, please add support for additional cryptographic algorithms beyond the default value OF THE used by ssh-keygen and other key generating default tools.

  In the meantime, if you have a control on the generation of keys, you can try using a different encryption algorithm but preserving the password requirement. The only solution would be to create the tunnel outside the SQL Developer and then manually create connections that run through the tunnel.

  With the script upload you the public key to the ESXi node.

  Note that plink.exe requires SSH to be enabled and running on the node of ESXi.

• VPN and SSH key phenomena

  Hi all

  I was in possession of a rather strange problem.

  Description of the problem

  I can't SSH in my ASA box within my network private and the Internet when it is not connected to the VPN without problem

  If I SSH to my ASA box of in a remote access VPN session, I get the error "ssh_exchange_identification: Connection closed by remote host".

  REMOTE_VPN_POOL = 192.168.250.1 - 192.168.250.5/24

  LOCAL_LAN = 192.168.2.0/24

  The strange thing here is that I can't SSH to my device without wire (192.168.2.2), then to my ASA (192.168.2.1) - see the text in bold below.

  The below and paste the job gives a good example of what is happening. Apart from this, the ASA works very well in terms of RA VPN. Any help on how to solve this problem would be greatly appreciated.

  See you soon,.

• Key issue of the external table preprocessor - ssh

  I want an external table that runs a df command in a script

  DFH.sh more

  / bin/df h

  CREATE TABLE XT_df

  (

  SCRIPT_OUTPUT VARCHAR2 (2000)

  )

  EXTERNAL ORGANIZATION

  )

  LOCATION (datapumpdir: 'xtdf.dat')

  )

  Select * from XT_df

  And it works.  I see my df output.

  I want to run something similar on multiple hosts, but the same host, so I place another table and call another shell script to run a remote ssh script after I have set user equivalence

  / usr/bin/SSH oracle@remotehost1 ' df-h | grep u02'

  the works of shell script

  However, qualifying by selecting in the external table I get ssh host checking has no error.

  [Error] Run (1: 1): ORA-29913: error in executing ODCIEXTTABLEFETCH legend

  ORA-29400: data cartridge error

  KUP-04095: order of preprocessor /winlogs/dfh.sh has detected the error "host key verification failed.

  "

  So what could be the cause that if she works well as oracle from command line, checking the .ssh key is on the other side (I think).

• SSH - private key location for ESXi?

  After generating RSA SSH keys to allow SSH without password from host ESXi5 to another SSH server, where is the private key file? The default location is/root/.ssh, which does not exist under ESXi5.  Does go in .ssh?  Has anyone implemented on ESXi5 and find out where the private key used for sessions outbound SSH is stored?

• remembering ssh passphrases

  Before moving on to the Sierra, the first time I ran a ssh command every day, he would ask for my password and store the key, making it usable by any other ssh process, no matter where I am connected, thanks to the "forwarding agent. That's what I'm used to and is identical to the way things work on my other computer (which runs on Linux).

  After upgrade to Sierra, passphrases my SSH keys are somehow being 'remembers', but no ssh-agent. I am able to ssh from my laptop directly in one of the servers that I managed, without being asked a password, but because the agent does contain all the keys (i.e. "ssh - add - l" returns "the agent has no identity."), I'm not able to ssh from this server to another server, which also makes the 'scp' and 'git' commands do not work until I go back to the laptop itself and run "ssh - add.

  I tried to use "Keychain Access" to find and remove the element containing the password, but no items in any of my files of trousseau (connection, iCloud, System or root system) contain 'ssh' anywhere in their title. I also tried 'ssh - add - d K' and 'ssh - add - d /Users/xxx/.ssh/id_rsa K. Neither the command seems to have no effect, they are not compensation everywhere where passwords are stored.

  The output of "ssh - vvv" Server1 contains the following items:

  How can I make ssh NOT remember passwords for my keys?

  Thanks to http://apple.stackexchange.com/questions/253779/macos-10-12-sierra-will-not-forg and my-ssh-keyfile-password , I found that the password is stored in ~/Library/Keychains/{UUID}/keychain-2.db, rather than in the keychain. It is a sqlite3 file and the element containing the sentence can be removed with the following query:

  ~/Library/keychains/*/Keychain-2.DB $ sqlite3

  SQLite > delete from the genp where agrp = 'com.apple.ssh.passphrases';

  SQLite > .q

  $

  The problem is, the next ssh command I type asks for the password and stores it in the same file again.

  How do you prevent ssh from store my passwords at all?

• MacOS Sierra not properly to access the Keychain for OpenSSL/SSH passwords

  Hello

  It seems to be a problem in the Sierra of MacOS on the passwords for SSH keys.

  I have my public/private key pair that is enabled for access to some linux servers, so I can't SSH in without inserting my password. After upgrading to Mac OS sierra, it seems that the keychain is no more long-term treatment/store/retrieve passphrases correctly.

  When first tried to open a session in one of my remote servers, asked me for the password, which seemed odd, so I thought that maybe the passwords were lost in the upgrade and changed the password manually by calling "ssh-keygen - f id_rsa Pei." Then I went to log in again, I asked the password and he entered, so I could connect to the server but then, apart from SSH telling me it has stored the password in the keychain, subsequent attempts to connect again always ask me the password.

However, next attempt will not find the password in the keychain, so that the process will be repeated "ad nauseam".
