search for: ssh_gai_strerror

Hi, I just tried to build the latest portable code from CVS on Cygwin. I stumbled over a problem with the definitions of gai_strerror and ssh_gai_strerror. On systems not having gai_strerror, the fake-rfc2553.c file defines its own version of gai_strerror, and fake-rfc2553.h additionally has this definition of gai_strerror: #define gai_strerror(a) (ssh_gai_strerror(a)) OTOH, misc.c defines the function ssh_gai_strerror unconditionally, and...

...configured properly, ssh shows a "Success" error message: /etc/nsswitch.conf: hosts: files dns xyz $ ssh nohost ssh: Could not resolve hostname nohost: Success The message "Success" doesn't make sense given that it's in fact a system error. It's an issue of ssh_gai_strerror() which can't handle a situation when getaddrinfo() returns EAI_SYSTEM but errno is not set/is set to 0.

I was wondering what everyone's thoughts were on a simpler way to exclude addresses from having listeners on them. I know a lot of people have multiple subnets, especially larger corporations. Some networks are non-route-able, and therefor unsuitable for use with SSH, aside from communication between other servers on the same subnet. Given that we may want to exclude those non-route-able

Changes since OpenSSH 6.4 ========================= This is a feature-focused release. New features: * ssh(1), sshd(8): Add support for key exchange using elliptic-curve Diffie Hellman in Daniel Bernstein's Curve25519. This key exchange method is the default when both the client and server support it. * ssh(1), sshd(8): Add support for Ed25519 as a public key type. Ed25519 is a

Hello! I'm hoping that Gmail won't HTML format this mail so that I'll get flamed :) Anyway, my question relates to ssh_config.
