• 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,.

• 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.

  com.jcraft.jsch.JSchException: privatekey: aes256-cbc is not available [B@2ef5d584
    at com.jcraft.jsch.KeyPair.load(KeyPair.java:654)

  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.

• SSH in APIC

  I can PING and HTTPS in my APIC, but can't SSH?

  Does anyone know why this might be the case?

  • SSH works this APIC before?
  • You can SSH to APIC2 or APIC3 successfully?  Leaf (s) & Spine (s)?
  • What has changed?  You've improved APICs?  If so, what version of what version?
  • In the policies of Pod, using access management strategy 'default' or 'custom name' management access strategy?  What is settings for SSH SSH & via the WEB?

• Is it enough for connection through SSH-2 RSA only, 1024, force 8 password?

  Hello world

  I provide the highest level of security on C2821-CCME-VSEC/K9.   Is it sufficient for connection through SSH-2 RSA only, 1024, force password: 8 symbols, no. CAPS letters, numbers, special symbols, example of password [homeless ^ & * 89]?

• Ssh/telnet/web ASA5505 question

  I can't access this ASA everywhere except the console.

  I'm no expert, ASA, but I compared it to others I have configured asa, and I can't find the error of my ways.

  It is expected to be easy, I just need a different set of eyes looking at it now. I hope I don't have too much censor, but I imagine that if I am able to SSH locally, will fix all issues of access I have.

• Protection of management plan

  Where is the configuration:

  Router(config)# control-plane hostRouter(config-cp-host)# management-interface FastEthernet 0/0 allow ssh snmp

  assists in IOS 15.4? This used to secure traffic management plan of specific interfaces so that Cisco would not listen on all interfaces for SSH traffic, etc. In IOS 15.4, I can't find an equivalent command and my VRF accept connections SSH, which is the only way I can stop with an ACL on each interface of the VRF. The procedure is described here: http://www.cisco.com/c/en/us/support/docs/ip/access-lists/13608-21.html#anc33 thank you

  That's all.  I just checked the navigation feature Cisco and Management Plan Protection requires the license of security.  It is not part of the data or intellectual property database.

• Password required but no defined (ssh)

  Hello

  I'm stumped... I have several 3750 switches x (IOS 15.0 (2) SE4) configured for authentication with NPS (RADIUS).  When I ssh in these switches, I can authenticate via Radius successfully.  However, when I type activate, I get this message: password required, but none set... password: __________.  He will accept my password to enable problem-free.

  I 3750 g switches and do not encounter this message when you type in my password to enable.

  I'm trying to understand what generated this message.  This is my setup for aaa loging and line vty:

  encryption password service

  AAA new-model

  AAA authentication login default group RADIUS local-case

  RADIUS group AAA authorization exec default authenticated if

  AAA - the id of the joint session

  password for admin1 privilege 0 [email protected]username / * / username //changed and password

  enable secret 5 *.

  line vty 0 4

  session-timeout 10

  Synchronous recording

  preferred no transport

  entry ssh transport

  transport of output no

  Thank you

  Bedside

  Bedside

  It is a bit of a strange behavior. I suspect it has something to do with the IOS 15.0 changes.

  I think part of the problem is that you have not provided any aaa commands of authentication for access to activate the mode. If you want to control access to activate the mode through RADIUS similar to what you do for the user mode? Or you just want to use the enable password. I think if you put that in the configuration that he could solve this problem. It might look like this if you want to use radius

  AAA authentication enable default group enable RADIUS

  or it might look like this if you want just the enable password

  the AAA authentication enable default

  One of them give it a try and tell us if it helps.

• [ACS 5.2] Administration of switch using SSH

  Hello

  I want to use LDAP accounts to manage the switches.

  It works fine when I use telnet.

  I just need to push the RADIUS-Service attribute of connection (ID 15) with the value of Telnet (ID 0)

  Now, I want to use SSH (for security reasons)

  RADIUS must push the RADIUS-Service connection (ID 15) attribute with the value of SSH (ID 50)

  (For example with the belt steel RADIUS http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?lang=en&cc=us&taskId=110&prodSeriesId=4174801&prodTypeId=12883&objectID=c02602225 )

  SSH value does not exist in the dictionary of the IETF RADIUS for Login-Service attribute.

  I can't create value SSH because this dictionary is protected...

  Is there a solution?

  Thank you

  Patrick

  Hello Patrick,.

  GBA 5.x will not allow change/remove/add attribute to the IETF RADIUS dictionary values as it is standard and reserved.

  If you check the RADIUS RFC to http://www.ietf.org/rfc/rfc2865.txt under the description of the Service connection the SSH service is not listed there:

  5.15.  Login-Service

     Value       The Value field is four octets.        0   Telnet        1   Rlogin        2   TCP Clear        3   PortMaster (proprietary)        4   LAT        5   X25-PAD        6   X25-T3POS        8   TCP Clear Quiet (suppresses any NAS-generated connect string)

  5.x access control system will not need to modify these dictionaries as IETF RADIUS to the documented standards.

  The best approach at this point would be to contact the seller of switches to determine how to enable SSH on these devices.

  I hope this helps. Kind regards.

• Information about TelNet and SSH

  Hi all... IM new here

  Its my first qstion

  Q: I would like to know more about TelNet and SSH... How... can its work you explain this...?

  Hi Muhammed,

  Welcome to the Microsoft forums.

  I understand that you need to know about TelNet and SSH. I'll help you with the information.

  The Telnet utility to connect to other computers over a local network or on the Internet. Unlike a modern Web browser, Telnet uses only the controls text to interact through the network. While this method is a little outdated, it is still used by advanced users to test a network or perform maintenance on the system. Telnet is included with Windows 8, but is disabled by default. You can use the control panel to activate Telnet and then perform the network with application basic commands.

  a. open Control Panel. This can be done through charms, Windows + X, or by conducting a search on the start screen.

  b. Select programs from the main menu.

  c. click on or turn off Windows features turn on and approve the application administrative.

  d. check the Telnet Client and Telnet Server (depending on what you need).

  e. click OK.

  You can see the following TechNet article to learn more about TelNet.

  http://TechNet.Microsoft.com/en-us/library/cc732339 (v = ws.10) .aspx

  SSH (Secure Shell) allows you securely transfer files between computers on a network. All the data involved in the SSH session is encrypted in order to protect against hackers. Once SSH is installed on your computers and servers, you can create passwords for individual users, using programs included in the installation of SSH. If you need to SSH to a remote computer, you need to download a third-party program to connect via SSH.

  I hope this helps.

  Please report if the problem persists and we will be happy to help you further.

• Apple Watch series 2 protective case

  Hello

  Has anyone found a real Apple Watch S2 case? You are looking for a minimalist design, to display the watch itself without inhibiting its look, then perhaps a clear case (case bumper or other) will do.

  All cases online specify that they are cases Apple Watch S2, but look further into what they are not, as many of them do not account for the new air port (hole on one side, not two) and are also not the right depth, and cutting a port speakers are designed for S1 S2 not.

  You will need to protect my camera, I do use it in the gym a fair bit and worry about the damage.

  Thanks guys and girls!

  Hi RudeBwoy!

  I had the same problem. As far as I can see, case or bumper for the AW 2 series do not exist. I talked to Spigen, catalyst and a couple of others and any sites third 3rd say... manufacturers confirm that their AW products are NOT compatible with series 2 Watch, and that they are working on it!

  All thoughts of good screen protectors? !! They would be compatible? Some protection is better than nothing!

  Let me know if you hear anything!

• Can't ssh on Mac OS VPN server

  I can connect to my VPN L2TP server with my iPhone running iOS 10 through my network of data carriers and passed to my home network from Comcast, but everything does not work;

  What works:

  Access default Web site running the macOS Server using its IP address

  Public Web surfing

  I can ping my phone of any system IP address on my network

  What does not (what I tried):

  SSH to any system macOS on my network

  Access screen sharing on any system macOS on my network

  Resolve the local hostname to an IP address

  More information

  my iphone is running iOS 10

  My computers are running macOS Sierra

  I use Mac OS as host VPN server

  I use the client VPN L2TP iOS 10.

  Firewalls in the system is disabled.

  Typical VPN connections, you use the DNS server of your iPhone and not the DNS server of the network corresponding to your server.  In addition, Hello services are only available on the LAN.  So you have no way to resolve names to IP adrdesses for the network, you are VPNing.

  The only easy solution from an iPhone is to make a list of IP addresses and use them to connect instead of host names.  using IPs will work as long as your ISP does not also use the same internal (like 192.168 or 10.0) IP address than the network that you connect to.
