• My ReadyNAS NV + is confused.

  Hello

  My ReadyNAS NV + seems to be confused. I was doing some winter spring cleaning top it - I went in a sharing and deleted a bunch of files. Rather than to remove them, all network shares disappeared. I restarted the NV +, but the shares are not returned. I also noticed that a car had 12 reallocated sectors.

  I bought a 6 TB external drive. I could always connect by SSH, so I backed up files with WinSCP 6TB to ~ 800 KB/s (Yes, it took about 2 months.)

  I then tried an OS reinstall. He finished, but the web interface came partially. No images, page malformed, had about 3 items/buttons on it rather than the usual number.

  After that, I tried a factory reset. It is now stuck at 'start... '. »

  Any thoughts on how to revive my confused NV +? Maybe it's time for retirement?

  12 is still a small number, but it is possible that the disc could be the problem.

  You could try a factory reset with only three disks in the system rather than four to see if the disk with the reallocated sectors is the problem that your next step. You don't need to move the disks.

• PIX 520 running 6.2 (1); SSH session limited exceeded; cannot reconnect

  Twice now, one of my PIX 520 s did not allow new ssh or telnet sessions and displays the following message on the syslog server:

  PIX-4-315005% SSH session limit exceeded %. Connection request of #. #. #. # on the _interfacename_ interface

  I think I understand the basics of what is going on, but I am confused about how to get it for free, and why it has suddenly become a problem.

  Both times I went to a physical console (via the nice blue cable) session and used the ssh session disconnect # command. There are 5 numbered 0-4 connections.

  Both times that do not release the firewall to serve ssh again.

  Help! Anyone have any ideas?

  It is a known issue (CSCdy05681 and other I think), must be laid down in the code of 6.2 (2).

• How the router can understand protocols such as SSH or telnet

  How the router can understand protocols such as SSH or telnet
  and device for layer 3 router

  second question, I found this accessory of CCNA security book Keith Barker
  wrote it router look at application layer information how?

  Thank you in advance.

  Hello

  I think that confuse you routing process.

  Router; route packages using their layer 3 address.

  This means not router cannot understand the upper layer protocols. There just transmission by addressess of layer 3.

  for example: we can define Access-list for tcp and udp layer 4 packets. router can decide whether to permit or refuse even if these lists filter by glance in the section layer 4 of the package.

  In an SSH or Telnet session, role of the router is terminal.

  Intermediate device belongs in the the router routing process.

• Cisco-sa-20120328-ssh

  This URL speaks a vulnerability with IOS code.

  http://Tools.Cisco.com/Security/Center/content/CiscoSecurityAdvisory/Cisco-SA-20120328-SSH

  But what is not clear is the following:

  Under the section 'Software Versions and fixes' find '12.2Se '.  Which version is the starting point for "releases until and including 12.2 (58) SE1 are not vulnerable?

  Interesting!  Which confuses me, too.  If in doubt, dig Bug Toolkit.

  Looking at the id of the bug of CSCtr49064 (indicated in the bulletin) on Bug Toolkit, we see that the fix appears explicitly in 15.0 (1) SE1 and 15.0 (2).

  By looking at the release notes for 12.2 (58) SE1, we see that this version only intoduced new features SSH to that codebase, so it would seem that the vulnerability was presented this way.  As a result, overall 12.2 (58) series IS seems to be affected (not fixed until the 15.x), but 12.2 (55) series IS was never affected (old SSH code base).

  There is no clear indication that a regression has been introduced, so I guess that all 12.2 (58) SE branch is affected, but the wording in the alert is in contradiction with this assessment.  I will reach out to the clarification PSIRT team.

  Best course of action: to avoid the vulnerability, down to 12.2 (55) SE (last) or uphtade to one of the branches 15.x fixed.

• 'customer support files required' problem connecting using vSphere via SSH tunnel

  I am trying to connect to my ESX Server using the vSphere by tunnel via SSH client. I did in the past, but it does not work now. I am fwding ports appropriate (443, 902, 903) and have done the "hosts" file entry appropriate, as well. When I try to connect, I get the expected certificate error, and when I reject, I get a dialog box saying that I need to download the "required client supports files ', and of course I can't download them from the site vsphereclient.vmware.com while I'm in the tunnel. I'm confused about why I get this message, because I can connect to the ESX Server using the installed version of vSphere, if I directly (i.e. without a SSH tunnel).

  Any thoughts? I am in urgent need of remotely administer my VMs, any help would be most appreciated.

  It turns out that VMWare Workstation is listening on these ports, and PuTTY tunneling is silently failing... so it seems that I connect to my ESX box, but not really. Deactivation of VMware Workstation, Server and the authorization server to fix it.

• How to disable SSH Shell warning

  We have activated the ESXi and SSH shell on our ESXi hosts because we need to run scripts with plink.

  Now in the vSphere Client a warning appears, stating that the two parameters have been activated. How we can disable this warning, because it is confusing and we cannot see if a real problem.

• SSH on ESXi4.1.0

  I'm bit confused about ssh on ESXi 4.1.0 activation each version has a different way.

  I can activate ssh with VI Client by enabling the remote technical support, but in the summary page, there is a warning on configuration problems (extra remote tch is enabled).

  Is there another way to do this?

• Confusion between display Navigator datastore, thin thickness vs, vs size put into service

  Hi all

  ESXi 4.1

  It's very confusing.

  The case is:

  A virtual machine is configured with 50 GB of HARD drive fine.

  (1) in the browser of data store, the display is:

  Size: 11 GB

  Provisioned size: 50GB

  (2) the size of the SSH vmdk file is 50 GB

  So my question:

  (1) what is the use of the real space of the virtual machine? 11GB or 50GB?

  In my understanding, since it is a provisioning, it should be 11FR. But why SSH it shows 50 GB?

  (2) why the VM with Vista, there no column 'provisioned size' in the browser data store?

  Thank you.

  If you use thin discs, the space used in your example is 11FR.

• Confusion with the file system OCFS2 OCR and voting disk RHEL 5, Oracle11g,

  Hi all
  
  I am trying to install the Oracle 11 g 3 node RAC database
  
  The environment on which I must make this implementation is as follows:
  Oracle 11g.
  Red Hat Linux 5 x 86
  Oracle Clusterware
  ASM
  Storage EMC
  250 GB of disk storage.
  SAN
  
  From now on, I am installing Oracle Clusterware on 3 nodes.
  
  I performed these tasks for cluster installations.
  
  1 configure the kernel parameters
  2 configure the user limits
  3 edit the /etc/pam.d/login file
  4 set up the groups and users to the operating system for Oracle Clusterware
  5. configure the environment Clusterware Oracle owner
  6. install the rpm CVUQDISK package
  7 configure the Hosts file
  8. check the network configuration
  9 configure SSH on all the Cluster nodes (equivalence of the user)
  9 enable SSH on all the Cluster nodes (equivalence of the user)
  10 installing Oracle Cluster File System (OCFS2)
  11. check the Installation of the (OCFS2) Oracle Cluster file system
  12 set the OCFS2 (/ etc/ocfs2/cluster.conf)
  13 set up the stack of Cluster O2CB for OCFS2
  
  BUT, here again the after that I'm a little confused on how to proceed. The next step is to format the disk and mount the OCFS2, directories of software... so, create etc.
  I asked my administration system to provide me with two partitions so that I could get in shape with the OCFS2 file system.
  
  He wrote telling me.
  
  * "Is what you want before I do it?" *
  
  * / dev/emcpowera1 is 3 GB and OCFS2.* format
  * / dev/emcpowera2 is 3 GB and OCFS2.* format
  
  * Those who are big enough for you? If not, I can re-size and re - format the *.
  * before I climb on the servers.*
  * the SAN is shared storage. / dev/emcpowera is one of the three LUNS on *.
  * storage is shared, and it is 214 GB. At the moment there are only two *.
  * partitions on it - the ones I have listed below. Can I repartition the LUN everything *.
  * as you want it.*
  * Where do you want that these climbs to: *.
  
  * / dev/emcpowera1 *.
  * / dev/emcpowera2 *.
  
  * I thought if this mounting technique would work as follows: *.
  
  * emcpowera1: / u01/shared_config/OCR_config *.
  * emcpowera2: / u01/shared_config/voting_disk *.
  
  * Let me know how you would like that mounted. » *
  
  Please recommend me what I should pass so that I can ask him exactly the same.
  
  My second question is, as we use the DSO, for which I'm going to configure ASM after clusterware installation, do I install Openfiler?
  PLS, check the environmental information that I provided above and make recommendations.
  
  As of now, I am using Jeffery hunters guide to install the entire installation. You think the installation guide everything is fine with my environment?

• 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.

• 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.

• 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:

  debug1: next authentication method: public key

  debug1: offering public key RSA: /Users/xxx/.ssh/id_rsa

  debug3: send_pubkey_test

  debug3: send packets: type 50

  debug2: we sent a publickey packet, wait for reply

  labl = "SSH: /Users/xxx/.ssh/id_rsa";

  nleg = 1;

  'r_Data' = 1;

  Svce = OpenSSH;

  }

  debug2: using Keychain password

  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?

• Confused about the new iPhone to load

  It seems that online, there are many variations on how to charge an iPhone the first times, we don't know what to believe.

  Historically, I charge my iPhone for a day the first time that I get it or after I got a refurb from Apple. My battery life has always been fantastic, representatives of engineering apply even told to say.

  This time, I couldn't wait to load the device as I normally would. I connected my iPhone to my PC, did a restore of backup and wait for the iPhone to be able to load completely (about 30 minutes).

  Given that I had a lot of things happens, I didn't have the opportunity to "condition" of the battery, charge of the day to the next, or as some reports say that I have to load it only via the provided OEM charger (not PC). Some say that your battery die completely and then get away after the phone two hours before recharging.

  All these 'new' information is downright confusing. And yet, I see Apple suggesting as a result a large part of these 'tips '.

  Any thoughts on pricing?

  There is no requirement to 'manage' load.

  Charge at any time, for any period of time.

  You can use the phone while charging.

  Don't deplete the battery at a low level.

  Another that these steps, no more measures need to be taken.

• Mac OS Server - local users on console does not.  The shared access or ssh on account works

  A Mac Mini running Mac OS Server has problems with authenticating the passwords of local users.  Users connect the console of the physical computer running macOS app Sierra and Server 5.2.

  I'm looking for a short solution from scratch user and migrating data to a new installation.

  My hunch is that there is an interaction with the server application.  The other Macs, I managed on the same network fail server and do not have these problems.

  I installed a new version of macOS Sierra and then migrate the old data server on using the migration wizard, but the problem persists.

  The server used to have users on the network, but they are all deleted, and all users are the.

  In application server, the only services running time machine, the caching server and file server.  DNS, DHCP and Open Directory services are disabled in the server application.

  A local user password will work normally when the computer is restarted.  But if the user disconnects, and tries to connect to or use the fast user switching back and forth between accounts, the password is not accepted.  On reboot, it will be accepted.

  In addition to passwords are not accepted, other errors when you try to connect to specific customers include:

  "Your account is not a valid directory.  For more information, contact your system administrator'

  or

  "On behalf of user that you selected is not available."  Check your network connection and try again to the user account.  If you are connected to the network, ask system administrator for assistance. »

  If a network is used to access the data of the user using the user name and password, it works.  Similarly, SSH'ing via the terminal using the username and password works.

  An admin user can change the password back and it usually works for one login.  Then the password is denied if the user disconnects or use the fast user switching.

  Thanks in advance for any help on this embarrassing problem!

  I should clarify: it's the passwords of local users on the Mac who stop working (for the connection or fast user switching), until the Mac restarts.
