Ars Technica reports of ?abandoned projects? on SourceForge being taken over by SourceForge with adware installers added to executables. arstechnica.com/information-technology/2015/05/sourceforge-grabs-gimp-for-windows-account-wraps-installer-in-bundle-pushing-adware/ This might be something to be wary of with FLAC considering the main focus for FLAC has moved from SourceForge to Xiph.org.

A few questions regarding the OpenSSH support for the Diffie Hellman key exchange algorithms: (1) Are the diffie-hellman-group-exchange-sha256", "diffie-hellman-group-exchange-sha1" , "diffie-hellman-group14-sha1" "diffie-hellman-group1-sha1" (as defined in RFCs 4253 and RFC 4419) the complete list of key exchange algorithms supported by OpenSSH? (2) Is there a

I'm not nearly knowledgeable enough in crypto to fully understand your answer, but I will try. I wonder why moduli are not automatically generated the first time sshd is started though. That would make much more sense than shipping a default moduli file but also asking everyone to replace it with their own. On Fri, Feb 15, 2019 at 5:50 AM Mark D.

Hello everyone.. I am fairly new to the patching format.. so I just decided to post a basic info about how to remove group1 and group14 diffie key exchange in OpenSSH. I know that they are listed as required in RFC 4253 but I don't want a client to have the choice to use a 1024 bit prime for the key exchange. If someone is getting into my system.. they should upgrade to a new client. I am a

Currently, dovecot generates two primes for Diffie-Hellman key exchanges: a 512-bit one and a 1024-bit one. In light of recent events, I think it would be wise to add support for 2048-bit primes as well, or even better, add a configuration option that lets the user select a file (or files) containing the DH parameters In recent years, there has been increased interest in DH especially in its

I have tried compiling wine versions 1.2.1, 1.2.2, and 1.3.12 on caos NSA 0.9 x86_64. All versions have the same behavior when I try to compile them. During configuration I get configure: error: FreeType 32-bit development files not found. Fonts will not be built. Use the --without-freetype option if you really want this. This occurs even though freetype.i386, and freetype-devel.i386 are

Dear OpenSSH developers, I've worked this week on an alternative key exchange mechanism, in reaction to the whole NSA leaks and claims over cryptographic backdoors and/or cracking advances. The key exchange is in my opinion the most critical defense against passive eavesdropping attacks. I believe Curve25519 from DJB can give users a secure alternative to classical Diffie-Hellman (with fixed

Here are three versions (patch against openbsd cvs) 1) repace nacl w/libsodium, so i could test 2) curve25519-donna 3) Matthew's public domain reference implementation. i'd vote for #3 -------------- next part -------------- Am 30.10.2013 um 07:27 schrieb Damien Miller <djm at mindrot.org>: > On Tue, 24 Sep 2013, Aris Adamantiadis wrote: > >> Dear OpenSSH

Hello all In a recent spate of paranoia we set our server (SuSE Linux 7.0, kernel 2.2.16) to use SSH version 2 and not SSH1. With openssh 2.3.0p1-5 running as client and server, we find that stdout output is occasionally dropped: ssh server echo "JJJ" usually emits JJJ, but sometimes returns nothing -- although the command is apparently performed. In the happy case the server logs

> 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. Can anyone confirm? Personally I'm on openssh-6.7. - Grant > You will be aware of https://weakdh.org/ by now, I presume; the take-home seems to be

Hi, I am using OpenSSH 2.5.2p2 on Solaris 2.7 (Ultra 10) with 64bit support and have the following problem when connecting with the ssh2 protocol to non-solaris OS: On the client side, I do: /local/work/lysis/bin/slogin -v -2 -p 2222 rs30 On the server side (AIX 4.3), the sshd runs as follows: aix/sbin/sshd -p 2222 -d Full output follows at the end of this mail. The server is compiled with

This is regarding openssh 2.3.0p1 (the following problem was seen on Linux client / server): I have a problem with openssh when i don't "login": ie. i do the following: ssh -2 10.1.6.13 echo 0 It doesn't print the "0". However, i can get it to print the "0" by doing the following: ssh -2 10.1.6.13 echo 0 \; sleep 1 using "ssh -2 10.1.6.13"

Hello, I am attempting to make public key authentication to work between OpenSSH 3.0.2 client on OpenBSD and SSH-1.99-OpenSSH_2.9 FreeBSD localisations 20011202. From reading sshd -ddd and ssh -v I can't figure out what goes wrong. Could somebody interpret the attached typescripts for me, please? Here's the relevant part from the server log and I don't understand it: debug2:
