Need info on Gastman/Astman
Has anyone used Gastman/Astman successfully? I have it up and running (Gastman win32), but have a problem with the creation of end stations on the map. I'm not sure of the format of the extension to use when creating a end station icon. Services like Conference bridge and Musichonhold seem to work ok (I use 555@mainmenu and 666@mainmenu) for the Icon extensions. IAX softphone seems to work

Keyboard Interactive Attack?
You need to disable ?ChallengeResponse? (aka keyboard-interactive) authentication, not password authentication, to protect against this attack.

Gastman
I've tried the precompiled version of gastman, but it does'n work properly under windows, so I would like to try to compile it under windows, so maybe it begins to work. I've tried to compile gastman with mingw, but the db3.1 libraries request the cygwin include files and libraries. Then I've copied the cygwin's include files and libraries to mingw's directory, but the make

Use of "no-touch-required" with "cert-authority"
Hello, In testing security key support in OpenSSH 8.2, I had some trouble making the ?no-touch-required? option in the authorized_keys file work in conjunction with OpenSSH certificates. I think I?ve figured it out, but I think there may be a bug in ssh-keygen related to this. To make ?no-touch-required? work with certificates, I actually had to do three things: Generate the security key with

Resident keys?
Hello, I?m trying out the ?resident key? functionality in OpenSSH 8.2, and I?m having trouble getting it to find keys that I?ve created. I?m trying to create a new resident key using: ssh-keygen -O resident -t ed25519-sk -f <filename> This creates a key, but I?m not actually sure it is creating a ?resident? key, as when I try to dump out the resident keys with either ?ssh-keygen -K?

Gastman crashes on Win32
Hi, The Win32 binary of Gastman crashes on Windows 2000 SP4. Same case on all my machines, no error, no log. Although, the CVS version works great on Linux. Is it anybody who knows how to compile it with mingw32 ? Or better, could anyone, who already has mingw32 installed, make a binary snapshot ?

Building libsk-libfido2.so?
I updated to the latest versions of libfido2 and openssh-portable tonight, with an intention to test out the security key functionality and look closely at the changes over the last couple of months to see if I need to change anything in my AsyncSSH implementation to stay in sync. However, it seems that libfido2 no longer provides the ?libsk-libfido2.so? library that it used to. That was something

OpenSSH 7.6p1 ssh-agent exiting if passed an invalid key blob
Hello, I noticed a problem recently when running some test code against the OpenSSH 7.6p1 ssh-agent. These tests ran fine against OpenSSH 7.5p1 and earlier, but with OpenSSH 7.6p1, they were suddenly causing ssh-agent to exit. The request being made was a ?sign? request, and the point of the test was to have the sign operation fail. To trigger this, I was passing in an invalid key blob

Question on Kerberos (GSSAPI) auth
I?m working on an implementation of ?gssapi-with-mic? authentication for my AsyncSSH package and trying to get it to interoperate with OpenSSH. I?ve gotten it working, but there seems to be a discrepancy between the OpenSSH implementation and RFC 4462. Specifically, RFC 4462 says the following in section 3.4: Since the user authentication process by its nature authenticates only the client,

Gastman compile errors
I seem to be encountering a problem with the db.h file when compiling gastman. Incorrect definitions for functions and so on.

Astsee v0.1 released - an Asterisk channel monitor for linux/X windows
Hiya everyone. I have been working on a fun little app to watch what's going on in your asterisk box via its manager interface. There's a screenshot up and some info at http://sitkavoip.com/astsee/ -- Sorry it requires allegro, but I was more keen about getting the ideas down than worrying about the framework. Comments/questions welcome, but probably off-list is best unless they

[PATCH] sshsig: check hashalg before selecting the RSA signature algorithm
There is no hash algorithm associated with SSH keys. The key format for RSA keys is always ?ssh-rsa?, and it is capable of being used with any of the available signature algorithms (ssh-rsa for SHA-1 and rsa-sha2-256 or rsa-sha2-512 for SHA-2). See section 3 in https://www.rfc-editor.org/rfc/rfc8332: rsa-sha2-256 RECOMMENDED sign Raw RSA key rsa-sha2-512 OPTIONAL
