Hello, I hope it's the correct ML to get support for "advanced" ssh use (sorry if it's not the case) And I would be very grateful if someone could help me on this issue. Here is my challenge : - I have X devices (around 30) and one SSH server - Each of them have a unique public key and create one dynamic reverse port forwarding on the server - All of them connect with the

Hello. I am trying to play through the following test scenario about certificate revocation on Ubuntu 18.04, which has OpenSSH of this version: OpenSSH_7.6p1 Ubuntu-4, OpenSSL 1.0.2n? 7 Dec 2017 1. A CA key is created ssh-keygen -t ed25519 -f ca 2. The CA public key is added to ~/.ssh/authorized_keys on some server: cert-authority ssh-ed25519 AAAA...e ca at yoga 3. A user key is created on a

As far as I can tell, there currently isn't a straightforward way to use password authentication for connecting to hosts where the host key changes frequently. I realize this is a fairly niche use case, but when developing software for devices that often get reimaged (resulting in a host key change), it can get pretty tedious to attempt to connect, get a warning, remove the old host key via

Hello everyone, I work in a setting where remote logins are usually authenticated with SSH user keypairs, but many target accounts need to have a password set nonetheless (to use with sudo, log in via remote KVM, etc.) and cannot be put under a central user administration like LDAP. Enter a corporate password policy that requires passwords to be complex, different everywhere, and of limited

Hello, I have asked on the postfix mailing list for a solution, how to encrypt incoming emails with public gpg key My original idea was to use a smtpd-milter, which would encrypt all incoming plaintext messages of given user, using the users public gpg key. This way, it would look as if the original sender has sent the message encrypted. Somebody suggested this might be better done in Dovecot,

Hello, given a small organization. There are *personal* mailboxes (mailbox per user, incl. subfolders et cetera). The users can share specic folders via the ACL (we call it "other users/", Dovecot calls it "shared" folder. Additionally there are mailboxes Dovecot calls "public" (we use the term "groups/"). They are not associated with a specific account,

Hi all, When I use an email client, its purpose is as a window into my Dovecot IMAP, and as a mechanism to reply to and send emails. I don't do filtering or calendaring on my email client (filtering via procmail direct to Dovecot). What email clients are all of you using to look at your IMAP email? Thanks, SteveT Steve Litt November 2016 featured book: Quit Joblessness: Start Your Own

Given the following: mailboxes: user1 at example1.com user2 at example1.com user3 at example1.com etc. aliases: whatever at example1.com -> user1 at example1.com whatever at example2.com -> user1 at example1.com whatever at example3.com -> user1 at example1.com Now the problem: example1.com MX goes elsewhere (doesn't point to this server anymore). Domains example2.com and

Hi, OpenSSH 8.2p1 is almost ready for release, so we would appreciate testing on as many platforms and systems as possible. This is a feature release. Snapshot releases for portable OpenSSH are available from http://www.mindrot.org/openssh_snap/ The OpenBSD version is available in CVS HEAD: http://www.openbsd.org/anoncvs.html Portable OpenSSH is also available via git using the instructions at

Hi everyone, I'm running dovecot with quite a lot of users and lots of active imap connections (like 20'000). I'm using different user IDs for users, so I need to have imap {service_count=1} - i.e. I have a lots of imap processes running. Everything works fine, until I reload dovecot configuration. When that happen, every client is forced to relogin in the same time and that

Hi to all I was looking at protonmail.com Is possible to implement and end-to-end encryption with dovecot, where server-side there is no private key to decrypt messages? If I understood properly, on protonmail the private key is encrypted with user's password, so that only an user is able to decrypt the mailbox. Anything similiar ?
