I am attempting to use the Knock.pm from http://www.shorewall.net/ManualChains.html I am not having much luck making the DNAT- knock work for some reason. Anyone else using this on 4.4.4 that can verify if this still works as documented?

...address to connect to specified knock ssh port (I used 32022 for my example), opens a listener for 30 seconds, then kills the listener and drops the iptable entry. #2 knock, to have the server ssh to the IP address specified, to open a back channel into the servers ssh daemon. This allows the knocking client to connect to the server over the R mapped port (I used 2022 for my example). The nice thing about this, is that the reverse mapping stays open until you kill the ssh connection. Now, my question is, where would be a good place to write this up, and share my sample scripts? Is there e...

I''ve been using the port knocking technique described in the Shorewall docs to control ssh access on one of our servers: http://www.shorewall.net/PortKnocking.html It works great, but occasionally one of the admins forgets to perform the close port operation. This leaves ssh open to the world until one of us notices. I''...

All, A friend gave me access to an svn(+ssh) repository the other day, and told me that I needed to do some port knocking to open up ssh. It occurred to me that it would be extremely convenient if I could add a "knock" configuration option for the host to my ~/.ssh/config file and never think about this again (rather than creating a shell script to accomplish this behavior, and remembering to use it...

I haven't been keeping up with the internals, I'm afraid. Does OpenSSH have support for Port Knocking? I might be interested in looking into that, as a way of reacquainting myself with the current code base. --- Scott Neugroschl | XYPRO Technology Corporation 4100 Guardian Street | Suite 100 |Simi Valley, CA 93063 | Phone 805 583-2874|Fax 805 583-0124 |

Anyone know why the knock-off X100p prices have jumped? -Nate

Hi guys, I've made a patch adding LocalPreCommand to ssh_config. It mimics behaviour of LocalCommand, but is executed right before the connection is opened. This makes possible e.g. to integrate ssh with port knocking. It also removes "-oPermitLocalCommand=no" from scp allowing the same functionality to be used for file transfers. Applies cleanly on vanilla OpenSSH 6.7p1. http://software.klolik.org/patches/openssh+localprecommand.diff Best regards, Bartlomiej Korupczynski

Hello Samba Friends, For those of you who have had to sift through Samba logs for clues on how to determine what caused an account to lock after repeated failed logon attempts, what "log level" settings have you found to be most helpful?

Thanks for taking a shot at helping me, Rowland. I found that someone had made this suggestion for another person in the past, so I ran this command before reaching out on Monday: > ldbsearch -H /var/lib/samba/private/sam.ldb -b "CN=Schema,CN=Configuration,$(echo "DC=$(hostname -d)" | sed 's/\./,DC=/g')" -s base objectVersion | grep 'objectVersion' | awk

In general we do not allow the removal of schema. In particular, because records in samba are stored under the attribute name, removing schema or renaming schema items describing those attributes and objectclasses can mean records cannot be processed correctly. However, if you confirm you really have exactly the entry already in the schema, you could edit the new schema not to add that

So I found an excellent port knocking tutorial using ONLY iptables rules that looks to be among the best I've ever seen. (warning: techno music, tough to read screen, you don't need to type it in because I post a link to script below) http://www.youtube.com/watch?v=0zFQocf7C_0 It works fabulously for simply opening a port...

Do they fall under FCC certification if they're built to the same specifications as the ones from Digium? If I build my own T100Ps from the schematics and board layouts that are available, are they legal to plug into the PSTN?

Andrew, I feel that it is your prerogative to determine how many odd possibilities you want your tools to account for, so that they might know what to do rather than exit with an error. You have a better sense for how likely it is that someone in the wild is altering their schema and might have changed an already existing attribute, as it seems I did. If you'd allow me to impose upon your

To radically cut down on SSH log spam you can also hide it completely behind a firewall, and allow access only by some port knocking sequence. I quite like having a process listen on port 53 and wait for a dns query containing a totp string to grant (temporary) access; that's a 2fa, and doing a "host 123456. my-ip" is easily automated in a shell script as well...

For what it's worth to those who want to play with SPA, here is a demo i whipped up. It is very easy to set up, and i almost guarantee anyone can get this running. What we will demonstrate: Bascially: An SPA demo. Requirements: Very little - a minimal setup of centos. This setup will demonstrate a client who initially cannot connect to a an ssh port on the server (the server is DROPing

I am trying to use rsinc to tranfer my ftp directory from one server to another. I have port 22 closed off due to port knocking and I am trying to direct rsync to use another port. Unfortunately I can't seem to get it to use the specified port. Here is my command, if someone could point out my error I would appreciate it: rsync -avr --port=XXX xxx.xxx.xxx.xxx:/var/ftp /var/ftp The error this generates is: ssh: c...

Hello James, Thank you for pointing me in the right direction. It sounds like Andrew Bartlett is committed to bringing this capability to a future version of Samba. Hopefully, he’ll find the process of adding this feature to be easier then he anticipates, and it’s available to all of us who need to perform forensics on failed logins. Have a great week, Matthew > On 2017.04.24, at 9:19 AM,
