Regarding openssh 8.1p1-1 access

Cygwin list mailing list
Hi cygwin community members,

My name is Sudhanshu Bhutani and we are working for one of leading network
service providers for our internal telecom tool. For the last few days, our
customers are reporting problems with our internal tool which uses cygwin
ssh and posix components.

We have a problem reported in the cygwin installation procedure, where
openssh  8.1p1-1 is not getting downloaded and cygwin mirrors are not
listing this  8.1p1-1 version and instead latest versions are listed.

How can we download  8.1p1-1 in cygwin?

Do you have any mirror/web link which our customers can use where open ssh
 8.1p1-1 is found and successful cygwin installation can happen?

I found one web link where openssh  8.1p1-1
https://linux.cc.iitk.ac.in/mirror/cygwin/x86_64/release/openssh/
is hosted, but cygwin says "Unable to get setup from linux.cc.iitk.ac.in
for openssh

Please guide me.

Sudhanshu Bhutani

Dear Sudhanshu,
version 8.1p1-1 is not more available on the cygwin mirrors
as was replaced by several new versions.

the latest version is 8.4p1-1

Cygwin is a rolling distribution, the last package is expected to be
the current one and to be used.

Regards
Marco

Thanks Marco.
Do you know of any mirror service - which can provide the old package -
maybe with some cost/revenue model? We can then ask our customers to add
that specific ftp mirror web link.
Any help would be appreciated.

Sudhanshu Bhutani

Security software like openssh should always be kept up to date to fix issues
and plug vulnerabilities which could allow yourself and your clients' systems to
be compromised. Cygwin typically only provides and allows the current and two
previous versions to be installed, in this case 8.4, 8.3, 8.2. Version 8.1 is
over a year old and should no longer be used; see:

        https://www.openssh.com/releasenotes.html

If you are concerned about how this is managed by Cygwin, you should provide
your own Cygwin package repository mirror, where you can control which packages
and versions are provided and made available.

Thank you Brian and Mike. We will see if cygwin time machine owners can
help us.

I will try contacting - [hidden email] - PETER CASTRO for any help.

Re: Regarding openssh 8.1p1-1 access

Cygwin list mailing list
One more approach - i was thinking was - can we package/include the
complete cygwin already [which already has older openssh version in bin
folder] installed folder to our tool exe without any modification?
Does it involve any violations for Cygwin GPLv3? Do we need to include
source code as well? Or can re-distributing an already created cygwin
folder can be done with freedom without any issues?

You can provide a private mirror of your own as suggested, which would be a
more future-proof way, but really you should investigate the cause of the
failing SSH behavior and fix THAT.
I suspect the fix would be way easier than setting up and maintaining a whole
mirror.

I have an urge to call the b-word.

Newer OpenSSH do support old ciphers, but they needs to be explicitly enabled
in config.
