Cygwin 3.4.9 - how to install ssh-keygen

Cygwin 3.4.9 - how to install ssh-keygen

[Matthias@gmx.li]

[-- Attachment #1: Type: text/plain, Size: 686 bytes --]

Dear all,

I've installed cygwin 3.4.9-1 in my virtualbox running on Windows 10.
After installing defaults plus openssh 9.5p 1-1, I open the Cygwin64-Terminal as Administrator and
run ssh-host-config.
 * Answered "yes" to create the /etc/ssh_config and /etc/sshd_config
 * Answered "no" to use StrictMode
 * and "yes" to install sshd as a service
 * I just press <enter> for the question for "Value of CYGWIN for the daemon".
cygrunsrv -S cygsshd will not start the sshd. The logfile say "no hostkeys available".

Unfortunately  I can't find ssh-keygen in the installable packages.
Howto install ssh-keygen or how to create hostkeys?

Thanks in advance
Matthias

That's quite strange, given ssh-keygen is clearly right there in that 
openssh package:

$ cygcheck -f /usr/bin/ssh-keygen.exe
openssh-9.5p1-1

The easy way to see if it's already installed
  $ which ssh-keygen
  /usr/bin/ssh-keygen

If no, Cygwin is a bit of a pain when looking for a program that's
included in another package.

There's probably a better way, but I use the cygwin package search - eg:
  https://cygwin.com/cgi-bin2/package-grep.cgi?grep=ssh-keygen
and then take a guess as the most likely candidate in the results list
and click on that link to see if it's included in that package - eg
  https://cygwin.com/cgi-bin2/package-cat.cgi?file=x86_64%2Fopenssh%2Fopenssh-9.5p1-1&grep=ssh-keygen

Thanks, I found it.

It is still not working. I'll ask for it in another thread with a better subject :)

Thanks a lot

I  can't see a command like

    cygcheck -p ssh-keygen

as noticeably more cumbersome than comparable commands of other
distributions

But you _can_ see/realize the implications of that command :)
I did a 'man cygcheck' before posting my reply, but somehow didn't notice

             -p, --package-query  search for REGEXP in the entire
cygwin.com package
                                  repository (requires internet connectivity)

which, in hindsight, seems really obvious but somehow I did miss it so
thanks for pointing it out!

Lee

Delete any manually created directories as permissions are likely wrong then run

	$ /usr/bin/ssh-user-config

Thank you,
$HOME/.ssh has been created with id_dsa and id_dsa.pub
rsa and ecdsa hasn't been created also if it said "*** Info: Generating /home/meyer/.ssh/id_..."

Now you can securely use ssh-keygen -A to create all default host key types or
ssh-keygen -t TYPE -a ROUNDS -b BITS -c for keys of any types and strengths you 
wish.

Hello

It isn't working for me :)
I run ssh-user-config. It asked me which keys I like to create and if I like to add them to
authorized_keys.

It create $HOME/.ssh with an empty authorized_keys and no keys:

No it didn't create ~/.ssh, the permissions are wrong.  It was surely 
created by you beforehand.

Remove that directory and start again.

Hello,

I installed cygwin 3.4.9-1 with all defaults plus openssh 9.5p 1-1 plus rsync 3.2.7-1 in my
virtualbox running on Windows 10 again.

In /var/log/setup.log I found "can't run /etc/postinstall/openssl.sh: No such file"
Anyhow, I opened the Cygwin64-Terminal as Administrator and run ssh-host-config but no host-keys has
been created:
   $ ssh-host-config

   *** Info: Generating missing SSH host keys
   *** Info: Creating default /etc/ssh_config file

   -rw-r--r-- 1 SYSTEM Administratoren 3.1K Nov 24 12:02 /etc/sshd_config

Also running ssh-user-config don't create any keys:
   $ ssh-user-config
   *** Query: Shall I create a SSH2 RSA identity file for you? (yes/no) yes
   *** Info: Generating /home/meyer/.ssh/id_rsa

   *** Info: Configuration finished. Have fun!

   $ ls -alh $HOME/.ssh
   total 4.0K
   drwxr-xr-x 1 meyer Kein 0 Nov 24 12:11 .
   drwxr-xr-x 1 meyer Kein 0 Nov 24 12:11 ..
   -rw-r--r-- 1 meyer Kein 0 Nov 24 12:11 authorized_keys

An indication of an installation/configuration error of ssh-keygen is that also
   /usr/bin/ssh-keygen -vvf /etc/ssh_host_rsa_key -N '' -t rsa
don't produce any output. Also if it has return value 0. BTW: Windows OpenSSH isn't installed on my
machine.

René Berber wrote that my files have the wrong permissions. But for shure, /home and /home/meyer has
been created during cygwin installation and /home/meyer/.ssh by ssh-user-config.

Which permissions the directories and files should have?
What could the reason be that ssh-keygen don't create any key? Looks like it wouldn't try it?

Thanks in advance
Matthias

Try this and look to the end.  Is there  perhaps a segmentation fault error?

        $ strace ssh-keygen

  I have a VM with Cygwin installed in it, which used to work for all the installed
packages.  However, after a recent update, all binaries linked to openssl now
produce silent segmentation faults.  Could be happening to you too.

OK, this makes the .ssh directory have the wrong permissions.

Real question is: Does ssh-keygen work with the wrong permissions?

My understanding is no, it refuses to create keys in those directories. 
And later other ssh parts will refuse to use them.

But I might be wrong.  The author of ssh-host-config certainly believed 
that StrictMode was not necessary.

Yes - That's the reason in my VM too:
   strace ssh-keygen -A

   Segmentation fault

I've tried to install openssl 1.1.1w-1 instead openssl 3.0.11-1. but it have Segmentation fault too
Is there a way to solve it?

I'm fairly certain that this is not Cygwin's ssh-keygen…

   :
   and all keys are created in C:\ProgramData\ssh

So it looks like cygwin ssh-keygen.exe have a problem :(
BTW: similar Segmentation faults I have with "strace /usr/sbin/sshd.exe --help" as well as with
"strace /usr/bin/ssh.exe --help".
Both are loading cygwin dlls like cygcrypt-2.dll or cygiconv-2.dll as well as Windows dlls like
ntdll.dll or kernel32.dll.

Any hints?

Thanks in advance

That intercept does not run under strace on my Win 10 latest patches system.
My strace shows DHCP contacted before running gethostname, then keygens.

Does this system run a legacy A/V?

Add to BLODA? - legacy embedded security provider interface:

Hi Lee,
cygcheck can help here as it can ask the Cygwin website

$ cygcheck -p bin/ssh-keygen
Found 6 matches for bin/ssh-keygen

A/V is Antivirus? My VM is running Avira. Deactivating it haven't impact on ssh-keygen. I still have

Does the cygcheck, ldd, or strace still show ntmarta?

If so, then it is likely the intercept might be installed and need uninstalled 
to deactivate!

If you are running Avira Free, I get:

	https://www.avira.com/en/free-antivirus-windows

"System Requirements

Your device is not compatible

Operating systems

Microsoft Windows 7 Service Pack 1 or above with the newest updates, hotfixes, 
and service packs installed

RAM

2 GB of RAM or more

Disk Space

Minimum 2 GB of free disk space (additional space for temporary and quarantine 
files needed)

CPU type

Intel Pentium 4 / AMD Athlon 64 Processor or faster (with support for the SSE2 
instructions set)

Browser:

Internet Explorer 11 or newer

Additional requirements

To install, you’ll need administrator rights, an internet connection, and a web 
browser. For automatic antivirus updates and optimal malware detection, you’ll 
need an internet connection"

So you should try that page from the system with issues, and try something else 
if you get the same response, as it appears that is pretty old code running, or 
just try something newer like MS Windows Security/Defender/etc.

Pardon the high jacking of this threat, but I may have the same problem (or, at least, it's related). I can start another thread if it is desired...

I am having the same problem with ssh. So, a little history... This is a fresh Windows 11 Cygwin installation. Everything works great, except using ssh. For example, when I type,

jcabrera@jicman ~
$ ssh jic@web

jcabrera@jicman ~
$

I get the prompt right away. I found out that Windows 11 comes with OpenSSH installed. I uninstalled it, rebooted, and reinstalled cygwin's openssh, and the problem is still there. I don't have any antivirus, except Microsoft's Defender, but I added two folder exclussions (c:\cygwin64 and the download folder for xmission download site). The strace of ssh is pretty long:

I think a clue here is that when *I* run Cygwin's ssh, which is successful,
I do not see ntmarta.dll.  This makes me wonder if it is something about
that, and also if it is something about the permissions on your .ssh folder
and files in it, about library search order, etc.

Try getting rid of Citrix.

Its the only significant difference I see with my working ssh trace (and 
all the other Windows libraries that one seems to pull just below the 
quoted line).

That seems to produce the crash in the Cygwin dll.  Perhaps using some 
of the same space?

Great - there are no (MS) ssh services running on your system, so no conflicts!

Great catch - Citrix is on BLODA as it tries to intercept a lot in every app:

Well, it's not Citrix. I have Citrix in all my machines (work stuff) and those instances of cygwin work ok. But, in any case, I disabled it, reinstalled everything, and still no luck. However, if I turn off the Windows Firewall, it works. So, now I have to figure that out. If anyone has any ideas, please let me know. I am going to start some internet searches and see what I can find.

You need to create a firewall exception for sshd on the machine you're 
trying to ssh into.

Hello

I had problems with Cygwin SSH not working after enabling "application protection" in Citrix. Disabling this functionality in Citrix made Cygwin SSH start working again.

Re: Cygwin 3.4.9 - how to install ssh-keygen - solved

[Matthias@gmx.at]

Hello,

After removing Citrix and install it again without "app protection", my segmentation fault has gone.
All is working now :)
It looks like this app protection is the reason for the segmentation fault.


Thank you for all the hints and your support

Indeed, Matthias is correct. I re-installed Citrix without the application protection and I am now back on business. Thanks all for the support and willing to help.

I am correcting myself on this one. It was Citrix and by re-installing and not checking the "application protection" checkbox, it's working. As we say in Spanish, just clearing the water... :-)
