Apologies for my late response. I am running different software now, but the 'bug' is still present. I can currently reproduce it as follows:
Server: openssh-server Version: 1:6.9p1-2ubuntu0.1, Architecture amd64 on Ubuntu 15.10 (wily) Client: Prompt 2 v2.5.2 (Build 23057) on IOS 9.2.1 (see https://panic.com/prompt/) My /etc/ssh/sshd_config mentions: > KexAlgorithms > curve25519-sha...@libssh.org,diffie-hellman-group-exchange-sha256 When my /etc/ssh/moduli is generated to contain only 4096 bit primes, and I log in from my iPad using Prompt 2, the server logs the following message in /var/log/auth.log: Mar 22 21:47:40 srv01 sshd[28876]: WARNING: no suitable primes in /etc/ssh/primes The file /etc/ssh/primes does not exist on the server system; neither is it mentioned in the (FILES section of the) sshd(8) manpage, which, incidentally, does mention /etc/ssh/moduli. - The above message is not logged in case /etc/ssh/moduli is generated to contain all of 2048, 3072 and 4096 bit primes. I hope the report is now as complete as it should be. In case I find other ways to reproduce the error, I will let you know. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openssh in Ubuntu. https://bugs.launchpad.net/bugs/1528251 Title: WARNING: no suitable primes in /etc/ssh/primes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/1528251/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
