Enable SSH V2

Hi, I have a 2960 switch 24TC-l with c2960-lanbasek9 - mz.150 - 1.SE.bin and SSH v1 active.

When I try to enable SSH v2 swith tell me that I need to create a rsa key encryption. I generated the rsa cryptographic key with 1024 bits, and when I try to activate SSH v2 I get the same message.

Damien,

This SSH session should not break the recommended operation. However, for maximum reliability, I personally would say using another method to access CLI (Console or Telnet) just to make sure that the SSH session is not get corrupted. In all cases, if the SSH session has been closed until the SSH keys are generated again, you no longer able to SSH into the device.

Best regards

Peter

  • Disable telnet, enable SSH

    What is the best way to disable telnet on the public (T1) interfaces of my router and enable SSH? Can I do this without setting up access lists?

    Thank you

    Diego

    You can. Type

    'transport input ssh.

    on the line vty 0 4 and it will only accept ssh connections.

    If you add access lists using access-class, it will add another level of security.

    You should also generate a RSA key for the router global configuration using the command mode,

    generate encryption rsa key

    Before you type this command, make sure that the domain name is configured on the router.

    IP - domain name

    HS key mypubkey rsa cryptographic will show you the RSA key that is generated.

  • Script to enable ssh on ESXi host.

  • ESXi4 enable SSH

    Hi all

    How to enable the SSH service do not have access to the remote server. Is this possible?

    The only access is available is VMware Infrastructure client.

    Best regards

    Play well.

    It's the same trick that I used. And has worked well for me.

    I have not found any problem related to a possible little sticky. Just use GZIP and TAR.

    A few days ago, I was looking on all Internet search engines to find out how to enable SSH on esxi.

    But on each of them, no body knew how to do this. So I decided to investigate all the vCLI Perl scripts and found the solution.

    Next time if I have another question I know where to ask for help (better than staying hours, around this).

    I think that you've already tried this, but for some reason you don't want to disclose.

    Perhaps because this isn't a recommendation from VMWare or VMware don't want this match or something else.

    Thanks for telling me that I wasn't the first person to know this trick.

    You're the man.

    a user name:

    ASA (config) # username, password testuser testpass

    and the system needs to know where are your useraccounts:

  • Enable SSH and disable Telnet

    I try to activate SSH on a 3560G switch so I can't disable Telnet.

    Some referred to a "sh-ssh' to see if I have ssh on the switch. It does not show. I also have 'transport input ssh' and ssh is not a valid input method.

    I've decided to update the IOS on the switch. I am now at 12.2 (52) SE.

    But I can not configure SSH. I get the same results as mentioned above.

    Since it is the latest version of IOS can't I not assume that it contains SSH? Or do I need to download another version of IOS who specifically has SSH in?

    Thanks for your help

    There are two versions of the images switch Catalyst (K9/SSH and SSH). If you do a ' show versi
    on "it displays the latest version of IOS running on the switch. If you run a non - ssh version, you must upgrade to a ssh (K9) image.

  • Enable SSH access to administrative accounts non-standard

    Hi all

    According to the administration of VCS Guide (p 298, x8.5.1), he suggests that "in general, local administrator accounts are used to access the VCS on its web interface or the interface API, but are not allowed to access the CLI".

    Well, I would like to make an exception then, how do I do this. The sentence that precedes suggests that exceptions are possible, but I can't find additional references.

    We looked at the ' / etc/ssh/sshd_config ', but of course, it is a read-only file structure.

    Any ideas?

    See you soon

    Chris

    I don't think it's possible, outside the admin account to access the CLI.  I know that the sentence says "In general", but to me, it reads as if all CLI access is reserved to all except the admin account.

  • Enable SSH via Powercli

    Is there a way you can toggle ssh via Powercli

    Hello, vicdaw-

    Welcome to the communities.

    Yes, you can turn on/off (start/stop), SSH (and VMHost services in general) with the cmdlets Start-VMHostService and VMHostService Stop .  As such:

    ## start the SSH service on the given hostGet-VMHostService -VMHost myVMHost0 | ?{$_.Label -eq "SSH"} | Start-VMHostService
    
    ## stop the SSH service on the given hostGet-VMHostService -VMHost myVMHost0 | ?{$_.Label -eq "SSH"} | Stop-VMHostService -Confirm:$false
    

    If you want to change the strategy of starting services, you can use Set-VMHostService. Enjoy.

    You can't at the moment from the GUI, until now the REST API calls. vExpert: Tomas Fojtahas this blog about using PowerCLI:

    From the Web of GUI client:

    1 / go to Networking & Security

    2 / NSX edges, then select the edge in question

    3 / on stocks on the block, select 'change CLI Credentials. "

    4 / there you can enable SSH

    Check: If SSH is already on the 'case' is already selected. Also you should be able to SSH into the edge now.

  • Activation of SSH on N2000

    Hello

    I'm looking to enable SSH/telnet to my Dell PowerConnect N2048 management. Currently I get timeouts when connecting to one. I followed the instructions on several forum posts and this guide:

    However, at this stage, I am completely puzzled. I generated the RSA and DSA keys, and the SSH server has been successfully activated. I've linked the VLAN 1 to a static IP address, which I suppose worked correctly (see IP in show run) I also created a user with the privileges of level 15. Currently, I am only able to access the console via a serial cable. SSH connection does not require a user name and expires instead. Here is the result of intellectual property see the ssh:

    SSH server active. Port: 22
    Levels of Protocol: Versions 1 and 2.
    SSH connections in use:... 0
    Maximum number of SSH Sessions:... 5
    SSH Session Timeout:... 600

    Everything seems good. I sent you a friends asking for additional information from the switch. The request of friends includes my email address. Additional information will help me to get a better look at the switch. I look forward to your email.
