Hello,

i have a problem to login to a CentOS 7 host.

On gentoo as client i have now the following installation:

[I] net-misc/openssh
     Available versions:  6.6_p1-r1 ~6.6.1_p1-r2 {X X509 bindist +hpn kerberos ldap ldns libedit pam selinux skey static tcpd}
     Installed versions:  6.6_p1-r1(15:22:37 06.09.2014)(X X509 hpn ldns pam skey tcpd -bindist -kerberos -ldap -libedit -selinux -static)
     Homepage:            http://www.openssh.org/
     Description:         Port of OpenBSD's free SSH release

When i try to connect to the client the connection hangs on:

Code: Select all

debug1: SSH2_MSG_NEWKEYS sent [preauth]
debug1: expecting SSH2_MSG_NEWKEYS [preauth]

Here's the output of the client and server connection:

Read from socket failed: Connection reset by peer

Does someone know where the Problem here is and how to fix that?
I think most of the Kernel Crypto-Modules are already installed. Also ssh from non-gentoo host works.

Thanks,
Toni.

Ok, solved it by:

Code: Select all

RekeyLimit default none

But in the end i think RedHat is stupid rubbish and i will not use anymore for myself..
It's all the same wit the commercial distro-sh**t doing always their own special way causing things to work more complicated and showing the "Distro-Specials" to be "the" professionals.
I can also write a bad documented stupid feature and then look like a master..
Oh, and i don't mean the OpenSSH-Bug with session rekeying here, only my experiences with commercial distros

But of course they will make a lot of money by buying for support..
