  Hi all!

  help me cope with configuring VPN from Site to site on ISA 570

  On two of the ISA, I created IPsec policies, but the connection is broken. What's wrong?

  

  

  When you assign the local subnet, you must set this on the other peer as a remote subnet, so "all" is false.

• ISA 570 DMZ SMTP ON DEFAULT_LAN SERVER ACCESS

  I have an smtp server in the dmz and area network extended with port forwarding. This smtp server will have access to another server smtp default_lan

  How can I create nat for access rules?

  Thank you

  Aondio Carlo

  Access rule:

  Area: DMZ

  Area: Default_LAN

  Services: SMTP (TCP 25)

  Source address: DMZ SMTP server IP

  Destination address: Default_LAN SMTP server IP

  Schedule: Always on

  Match Action: permit

  You don't need to create an access rule to allow traffic from the Default_LAN on the DMZ SMTP server as it will be allowed by default.

• ISA570 DNS internal blocking

  Hello

  I have a new client that I recently installed an ISA 570 to replace a Cisco 1800 router. The customer has a DHCP/DNS internal (10.1.0.10) server that is on the default subnet (10.1.0.0/16). After about an hour the DNS no longer works and the server can no longer access the Internet. The server cannot ping the gateway by default either, but it can ping on its subnet on the other clients.

  Between the ISA 570 and the server is a managed switch that is unmanaged, but I connected directly to ISA with the same results. After a few hours of troubleshooting, we changed the IP address of the server (10.1.0.5) and it started working. Eureka! then an hour later it stops working again. I turned off each additional safety on the ISA function. I have since changed to the 1800 router and have 0 problems.

  I'm puzzled. I made a screenshot of the interface by default ISA package and looked at wireshark. I see the number of packets from the server and 0 with it as a destination.

  last code 1.2.17 and tried 1.2.15 just to check

  any help would be appreciated.

  Thanks in advance

  Try it to point to the ISA and see if that helps. Shouldn't really make the difference and a little stabbed in the dark, but what you feel doesn't really make sense or the other, since you have all the security features disabled. My thought is that it is to see multiple requests to a single host DNS when he expects to manage the DNS. As I was saying, stab in the dark. ;-)

• VPNGroup and MS ISA?

  Hello

  I have a PIX 501 running V6.3 and already have VPN users destined for the external interface of the pix using the VPNGroup, but I wanted to see if this is possible.

  1. I want ti will not only have the name and the password for the vpngroup to allow them access I want to add the prompt for the user ID and password so that they must provide proof of identity valid AD and the password before they can complete the vpn connection. I want to use MS ISA to be able to do. I found the doc were it shows how to authenticate with a local user, but not tie it in the accession of the AD.

  2. I would also enable remote ssh rights administrator for the pix of anywhere, is it possible without having an exact IP address? I know of a prospective security that this type of access is not recommended, so if anyone has any suggestions I would be very happy.

  Thank you!

  Brian

  1. of course, it's what you're looking for (http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_configuration_example09186a00800b6099.shtml).

  Simply add the commands:

  vpnaccess AAA-server to the radius Protocol

  AAA-server vpnaccess (inside) host x.x.x.x Bonneau

  customer of authentication vpnaccess crypto card

  This will make all users to authenticate via Radius Server to x.x.x.x, you will have to configure it to work with your AD domain name.

  2 SSH access must be opened by IP address, but if you do not know the address the user IP will come, just enter the following to open access to all IP addresses:

  SSH 0 0 outside

  Of course, this has security implications as you mentioned.

• 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:

  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?

• 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.

• Unable to ssh on alternative port

  Mini Mac OS X Server 10.11.6, CommuniGate Pro, no and almost no other stock OS X Server services.

  The server owner recently found on a network that has blocked ports for VPN and SSH connections, so we try to set up the server to allow a SSH tunnel through SOCKS proxy port 443, which is almost always open. (We have no plans on execution of web services via this port on this area.)

  Research indicates that this should be a two-step process: 1) Edit /Library/Server/Web/Config/Proxy/apache_serviceproxy.conf to remove the web listening on ports 80 and 443 ports; (2) edit/etc/ssh/ssh_config for add a SSH listener on port 443. then restart.

  After that, HTTP services are off on 80 and 443, but I can't connect to SSH on port 443. Works very well over 22 yet. Nmapping the server indicates that there is nothing open on port 443. Is there anything else I need to do for this open?

  A user on the stack Exchange responded to this question. Works a charm.

• SSH permissions

  I know that this has been done, but I can't find here or elsewhere.

  I just reinstalled my SSH protocols after replacing a hard drive on the server and (data only) restore from a Time Machine backup. I seemed to have to start the SSH process from scratch.

  I'm from the procedure (which I learned here) ctlow.ca/SSH-VPN_MacOSX.html.

  It worked, but when I connect from the client, it just goes through without asking for password. I think that he asked a password the first time, the password private key (?), but he used to ask for it (in a small text box, echo) every time and then the password (?) server in the Terminal itself, not taken over.

  Now, none of those happening.

  So, I found some notes I had made about it and reset the permissions as 700 .ssh folder and files inside like 600, on the server and the client.

  It ends up looking like this:

  ClientComputer: ~ ClientID$ ls - ael .ssh

  Total 24

  drwx - 5 personal ClientID 170 11 Sep 15:24.

  drwxr-x-wx + 24 personal ClientID 816 13 Sep 08:26...

  0: Group: everyone deny delete

  -rw-@ 1 personal ClientID 32 10 February 2012 config

  -rw - 1 1766 11 Sep 15:11 id_rsa personal ClientID

  -rw - 1 818 11 Sep 15:33 known_hosts personal ClientID

  ====

  ServerComputer: ~ ServerID$ ls - ael .ssh

  Total 16

  drwx - 4 personal ServerID 136 11 Sep 15:28.

  drwxr-xr-x @ 25 personal ServerID 850 11 Sep 15:30...

  0: Group: everyone deny delete

  -rw - 1 416 11 Sep 15:28 authorized_keys personal ServerID

  -rw - 1 391 11 Sep 15:26 known_hosts personal ServerID

  I don't think I'm particularly threatened, but I was happy to have to use two passwords to log into the SSH tunnel. No idea why I wonder no password now? (I did specify a passphrase when generating the key.)

  Thank you.

  Charles

  P.S. The customer running 10.9, 10.11 server.

  P.P.S. For the client-user info window showed "shared folder" which I don't know how it got that way and have unchecked the box. I doubt if that is related to my question.

  Hello Charles,

  I'm not sure what you were doing before, but it seems OK now.

  Most of the internet uses the same set of instructions that tell people not to use a password for the private key. It's a hassle to the running ssh-agent and most people struggle enough as it is with ssh. But on OS X, keychain using ssh-agent. Thus, when you provide a password for your private key, the first time you go, you will be asked (via a beautiful Aqua GUI) your password. You can expect that and save it in the keychain, hence, you will never be asked again. Then, if the rest of your ssh stuff is correct, it will pass all by as you describe. It sounds like what is happening now, and that's how it should work.

  If I were to speculate, I think that maybe before you run a custom build of ssh and ssh-agent command line version. This would explain the double Terminal passwords can be made echo and the other not.

• 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.

  Note how he is unable to find the password in the keychain (it is out of the attempts of the second and following), then he says it stores the password in the keychain, and then, he considers it and "updated" it. However, next attempt will not find the password in the keychain, so that the process will be repeated "ad nauseam".
