similar to: [Bug 2047] New: Definition of Sophie Germain primes is wrong in manual moduli.5

Hello, I was re-generating the moduli for SSH, and during that process I noticed that, when running the following command: ssh-keygen -M screen -O prime-tests=600 -O generator=3 -f moduli-2048-01.candidates moduli-2048-01c It does not produce any errors, only the following: ebug2: ???1467763: (4) Sophie-Germain debug2: ???1467763: generator 0 != 3 debug2: ???1467764: (4) Sophie-Germain

Hi, You will be aware of https://weakdh.org/ by now, I presume; the take-home seems to be that 1024-bit DH primes might well be too weak. I'm wondering what (if anything!) you propose to do about this issue, and what Debian might do for our users? openssh already prefers ECDH, which must reduce the impact somewhat, although the main Windows client (PuTTY) doesn't support ECDH yet. But

> Can this be addressed in ssh_config/sshd_config with the KexAlgorithms setting? weakdh.org/sysadmin.html recommends adding: KexAlgorithms curve25519-sha256 at libssh.org But this thread makes it sound as if it's not necessary.

Hi, Can anybody briefly explain the significance of the updated moduli file? Is this a critical update? Should all existing installations update their moduli file? Thanks in advance, -- Dan

Hello, I'm using Sambsa 2.28 and I've just installed Sophos anti-virus and sophie 3.04rc2. If I run sophie standalone to scan a directory/folder it all runs ok, as it also does in daemon mode. I've changed my smb.conf file to specify vfs option=/usr/lib/samba/vscan-sophos.so When I access the share I receive the following in the syslog: samba smbd_vscan_sophos[6649]: ERROR:

Hi folks, This applies to src/share/man/man5/moduli.5 in the OpenBSD source tree, and doesn't seem to apply to the portable OpenSSH, so I've sent this change here instead of via Bugzilla. The wording of moduli(5) implies that sshd puts more thought about which modulus it selects than it really does. The following patch corrects this. Simon. -- Simon Burge

Hi, my question is related to the kex algorithm diffie-hellman-group-exchange-sha256 and moduli generation. I've seen that through ssh-keygen, I'm able to re-generate my moduli file used by DH but I'm note sure to understand one point in the ssh-keygen manpage : "Screened DH groups may be installed in /etc/ssh/moduli. It is important that this file contains moduli of a range of

Hello all, I propose the following patch to ssh-keygen.c for openssh version 4.5.

[ OS: Solaris 2.8 ] Curious why 'moduli' is installed in the "--sysconfdir' directory? Isn't this machine-independent and therefore should go in the "--datadir" directory? Also, it seems to me that the datadir/sysconfdir/sharedstatedir/ localstatedir would be more useful if they were set up (or further expanded) to better support packaging of OpenSSH. For
