• SSH on vShield Edge using Java CCES

  I am trying to connect to vShield Edge using jsch for SSH connection library.

  Connection to a linux server it works perfectly, but connected to the vShield edge server, the output is:

  vtysh: invalid option-'c '.

  Try "vtysh - help ' for more information.

  What it means?

  The connection seems to work correctly, I think the problem is the command I want exec ('list' command).

  I tried many commands, but I always have the same answer.

  I also used this methos Java to set the Pty:

  (Channel) .setPtyType ("vt100") (ChannelExec);

  Can I define another type?

  Thank you all

  I was determined to uisng the ssh-tool Java library

  You can retrieve the lib since this link sourceForge: SSHTools | Free software on SourceForge.net downloads

  And here is my code.

  Was indeed a problem of reading of the result of the command, but it should be simple to solve.

  public {} public static void executeSSHCommand (String username, String password, String hostname, string command)

  SshClient ssh = new SshClient();

  PasswordAuthenticationClient auth = new PasswordAuthenticationClient();

  int result = 0;

  Session SessionChannelClient = null;

  OutputStream out = null;

  BufferedReader in = null;

  try {}

  SSH. Connect (hostname, new IgnoreHostKeyVerification());

  auth.setUsername (username);

  auth.setPassword (password);

  result = ssh.authenticate (auth);

  If (result! = AuthenticationProtocolState.COMPLETE) {}

  System.out.println ("authentication error");

  }

  session = ssh.openSessionChannel ();

  session.startShell ();

  out = session.getOutputStream ();

  out. Write (Command.GetBytes ());

  in = new BufferedReader (new InputStreamReader (session.getInputStream ()));

  Read string = null;

  While ((read = in.readLine ())! = null) {}

  System.out.println (Read);

  }

  } catch (IOException ex) {}

  }

  }

• The EA8500 supports DHCP Option 60/61?

  Hello

  I was wondering the EA8500 can be used with sky fiber Pro service to the United Kingdom? Obviously I would need to extract the username of the SR101/102 and then intend to use the modem Openreach VDSL2 with the EA8500 (btw brilliant router) but after some research, I understand the router needs to support DHCP option 60 & 61 in order to connect with the sky. The EA8500 does it take?

  See you soon

  psycho

  Linksys engineering has notified me that the EA8500 is not compatible DHCP Option 60/61.

  Filed a feature request in support of these DHCP Options. Lets hope it is approved and included.

• Question of DHCP Option 50

  I understand that the DHCP 50 option is for the customer asked the IP address.

  I have 3 questions about this...

  1. the DHCP server on the router maintains the MAC--> IP mapping during 24 hours right?

  What happens if I ask a non assigned a different IP address in the 24 hour window? My request will be granted each time?

  What happens if I ask for an IP address not assigned different after the 24 hour window? I guess that my request will be granted every time in this case.

  2. always in the window of 24 hours, if the requested IP address is leased to another network device, but the device has long been disconnected,

  I get the requested IP address?

  2 do all versions of routers support this option?

  Depends on the implementation of the DHCP server. The RFC does not say how to handle 50 option. The DHCP server can but should not affect the requested IP address. It can completely ignore this option.

  So:

  How long the server retains the mapping? Depends on the server. It may or may not remove the mapping after the lease has expired (which I assume is the 24 hours, that you reference).

  Ask a different IP address during the valid lease? Depends on the server. The server may grant each time. Another server can refuse each time.

  I think it is more common to not to grant the request. Internally the DHCP server manages static IP mappings and pool all the same except the static IP mapping has an unlimited lease duration. As long as a request from a computer comes that already has a mapping (static or pool) he always attributes known IP address and the other does not.

  After the expiry of the lease? Depends on the server. A DHCP server keep the maps even after the expiry of the lease. The simple purpose of this is that if you have a fairly large pool that gets not exhausted you basically assignments to static IP addresses to DHCP clients. Even if a client releases the lease (because the computer is stopped) or the lease expires, he will always keep this information. Next time (for example, you turn on the computer after the weekend) it will always go to the same IP. But again, it is up to the implementation of the server. Other servers follow other policies and do differently.

  Address IP lease request? N ° never. The DHCP server must not assign an IP address that has been rented elsewhere. There is no reliable way to make sure that the DHCP server as other devices is indeed off. If a unit is stopped, it must release the DHCP lease. If it is not the case, the IP address is blocked until the lease expired. The only case that a transfer could occur is if the DHCP server has been reset and lost its DHCP lease table. In this case, the DHCP server does not know before granted leases.

  Supported? All DHCP servers must be able to receive DHCP requests include this option. It is the implementation of the DHCP server if the DHCP option is really accepted or not. Some servers may completely ignore this option.

• LWAPP AP - DHCP Option 43

• Cisco SPA with problem of DHCP Options 66

  Dear all,

  I have a problem of my phone Cisco SPA for the autodeploiement.

  If I manually enter the page configuration and paste "[- pwd - password user uid] http:///dms/def/spa$PSN.cfg" in the profile rule. Everything works perfectly.

  However, we would like to do in the provision of zero touch, I add the "[- pwd - password user uid] http:///dms/def/spa$PSN.cfg"DHCP Options 66. " The SPA phone seems impossible to get the 66 Options parameter. It shows that "/ spa$ PSN.cfg" in the rule of profiles.

  I'm sure that the DHCP server works perfectly.

  Can anyone help on this?

  Kind regards

  Desmond

  You cannot use the custom during initial deployment (zero touch) password. DHCP can be used to deliver key to the device in this way.

  Ok. What are the options you have?

  You my use of the configuration file, compiled with SPC type -target option. It encrypt the file by using the password from each device Mac so you need no password given to the device - device can calculate the password required their Mac. It provides just basic security level - insensitive user, like me, know the algorithm used for password generation so that it can calculate the password and decrypt the file.

  You can use HTTPS with mutual certificate authentication to deliver XML or SPC configuration form. All phones have the unique client certificate, then you can be sure that the request has been issued by the unit. It offers a high level of security.

  There are also a few other possibilities, but disclosed so that information on the goal you want to hit, so I can't list.

  Just note that DHCP will meet anyone, in addition, the answer may broadcast (therefore handed to anyone, even without prior request). If you deliver critical data via DHCP, you can consider them publicly available. Security resulting is without security.

• Microsoft DHCP - Option 43 Setup Server

  I have the scope properly configured insofar as the 241 Option with Option 43 and the VCI in for both the series 1130 and 1200 AP however, how can you do this job if your subnet has 1200 and 1130's inside? Basically if I have two 241 options set, the 1130 comes by first allowing the 1130 s associated, but not the 1200. If I remove the Option 241, the associated 1200 1130. Basically, how can I get both working properly the scope?

  Thank you

  Hi Pierre Roussy.

  Here is some additional info;

  This section contains an example configuration DHCP Option 43 on a Windows 2003 Enterprise DHCP server for use with the lightweight access points. For other implementations of DHCP server, see DHCP Server documentation to configure DHCP Option 43. In 43 of the Option, you must use the IP address of the management interface of the controller.

  --------------------------------------------------------------------------------

  Note that DHCP Option 43 is limited to a single access point type by DHCP pool. You must configure a separate DHCP pool for each access point type.* *.

• DHCP option to set the controller IP for Access Points (Airespace)

  Hello world.

  Does anyone have an idea to specify the controller using DHCP options.

  We use:

  -Controller AIR-WLC4404-100-K9

  -AP-1010-AP-5312 poinst access

  -Server dhcp DHCPd ISC 3.0.1

  Newspapers on DHCP server indicates that access points become the IP addresses, but the controller information are not "read" / "included".

  In the productive environment, controllers will be redundant.

  So far, we couldn't sucsessful with eighter of these configurations:

  Block i. using VTL:

  http://www.Cisco.com/en/us/products/HW/wireless/ps430/products_quick_start09186a00805100f5.html#wp49287

  subnet 10.50.107.0 netmask 255.255.255.0 {}

  option subnet-mask 255.255.255.0;

  routers option 10.50.107.1;

  option domain-name-servers 10.20.51.11, 10.20.51.12;

  option vendor-class-identify Airespace 1200;

  the option dhcp-client-identifier 0xf1, 8, 10.20.51.254, 10.20.51.249;

  DDNS-updates

  DDNS-rev-domainname "in - addr.arpa.";

  default-lease-time 28800;

  range 10.50.107.101 10.50.107.200;

  }

  II. using the DHCP Next-Server option:

  subnet 10.50.107.0 netmask 255.255.255.0 {}

  option subnet-mask 255.255.255.0;

  routers option 10.50.107.1;

  option domain-name-servers 10.20.51.11, 10.20.51.12;

  Next-server 10.20.51.254;

  III. use of Header Information Option 43 described such in DHCP Manual:

  WLAN-apc code 60 option = text;

  ip address wlan code option 43 = controller;

  subnet 10.50.107.0 netmask 255.255.255.0 {}

  option subnet-mask 255.255.255.0;

  routers option 10.50.107.1;

  option domain-name-servers 10.20.51.11, 10.20.51.12;

  option wlan-apc "Airespace.AP1200"

  option wlan controller - 10.20.51.254;

  IV. using header to the DHCP server information:

  class "-classes of suppliers ' {}

  vendor-class-identifier option match; }

  {"Airespace.AP1200" subclass "-classes of suppliers '}

  Next-server 10.20.51.254;

  }

  Does anyone have a working (using the SAI?) configuration or advice?

• RV042 150 DHCP Option

  Hi people

  I have a RV042 VPN router with the latest firmware v4.2.1.02.

  This router is connected to the main site through a VPN Tunnel.

  Now, I want to configure a DHCP Option if I can put an IP phone

  behind the RV042. The IP phone should receive an IP by DHCP

  the RV042 and of course, the IP address of the Director with the

  Option of 150.

  I can configure DHCP and it works fine but I can't find where I

  or can configure Option 150.

  Does anyone know ho it works?

  Thank you for your help...

  Kind regards

  Pascal

  Unfortunately RV042 isn't compatible DHCP Option 150.

• VShield Edge Configuration

  Hello

  I recently installed vshield Edge:

  There are two device that have been added to the inventory...

  I set up an internal IP address as my private subnet AND an uplink to have a public IP... and I configured the default Gateway to match my public by default Gateway...

  now I have a machine virtual on my private network that I change the gateway is the IP address assigned to the internal interface of vshield Edge... But it is still not Internet ping!

  Am I missing or wrong configured something?

  Help, please

  Thank you

  Hello

  The reason for two devices could be that you may have installed Edge in HA mode.

  Coming to your network problem, check the following.

  • Check if you have applied the SNAT rule on the external network. In this, the initial INVESTIGATION period should be your private IP network and the translated IP must be one (or) range of your public IP addresses. You must allocate under the IP translated before using NAT.
  • Check if the firewall is disabled (or) added with one exception.

• VShield edge Nic

  Hello world

  I installed VSphere 5.5, 5.5 VCloud and VShield 5.5 for a test. Everything seems fine. But when I create an organization VDC and add an EDGE gateway for him, the automatic system create a VM VSE under "system vDC". Virtual machine contains multiply network cards, including two he uses for the external network and the Organization's network. But there are still many that connect to a standard switch named 'None '.

  Although it works well, the problem is I can not migrate or do his host in maintenance mode. During the migration network interface adapter, it shows"2 use 'none' network, which is not accessible. »

  Does anyone know something?

  Thank you

  This should be a non-issue.

  Each vShield edge device has 10 NIC cards.  One will be attached to a given network (an external, one internal).

  The 'None' network, a group of port assigned.  This does not block vMotion does not happen, and I was

  Even if you get one! ------warning message, you should still be able to click Next and complete the vMotion.

  The only way you would be blocked from vMotion is if one of the two real networks were somehow connected to a specific host.

  Can you provide a screenshot of it with the next button grey and everything that is not a warning to the network no?

• Problem assigning vShield edge licenses

  We have a cluster running vCenter 5.1 standard with 3 hosts ESXi 4.1 under license with vSphere 4 Enterprise Plus keys. Recently, I've deployed a vCloud Director 5.1 with a Manager Server 5.1.2 Server vShield. I was able to successfully add the vCenter vCloud and vShield Manager. Then when I try to add our license of vShield edge in vCenter as the installation guide document, I can't find the CIS or POSSIBLE asset in vCenter section "permit". Is it because we lack of vSphere 4 license?

  

  The problem is now resolved. Recently, we are improving our vCenter 4.1 to 5.1. The appliance Manager vShield was installed before the upgrade. After the upgrade, I didn't perform a reboot of the vCenter server. Once I restarted the server vCenter, he was able to found the vShield active Edge of the appliance Manager vShield.

• vShield Edge balancer to load within vCloud Director?

  Hi all

  I had a long week, installation and configuration vCloud Director. So far, it looks great.

  However, I wanted to create a paralytic with 2 web servers and a LoadBalancer (vShield Edge device) in front of them. I just don't seem to be able to find anything about how I activate on the web site of vCloud Director. I can do the NAT and firewall, but balancing is missing ... I'm sure it's there somewhere, I'm just not see it!

  Can someone point me to the right direction?

  Bgrds,

  Finnzi

  This requires the additional license for vShield edge and configure vShield to vCenter PLugin.  There is no user interface in vCD interface to configure the load balaning VSE again.  1.5 introduces the possibility to configure VPN (if authorized), through vCD, but not the LB function again.
