Top Forums UNIX for Advanced & Expert Users Disabling CBC Cipher mode causes login problems Post 303034950 by Neo on Thursday 9th of May 2019 11:45:04 PM

Does this command work on Solaris?

Code:
ssh -Q cipher

Sorry, I don't have a Solaris box handy.

Please run ssh -Q cipher and update us with the results.

Also, Oracle says this is all you need to do to disable those weak ciphers:

Code:
   
cp -p /etc/ssh/sshd_config /etc/ssh/sshd_config.`date +%d-%b-%Y-%H-%M`

vi /etc/ssh/sshd_config

Ciphers aes128-ctr,aes192-ctr,aes256-ctr
Macs hmac-sha2-256,hmac-sha2-512

svcadm restart ssh

Edit and Update:

I see from the Oracle docs that Solaris does not support ssh -Q

Oracle Docs: ssh - man pages section 1: User Commands

SSH-LDAP-HELPER(8)					    BSD System Manager's Manual 					SSH-LDAP-HELPER(8)

NAME
ssh-ldap-helper -- sshd helper program for ldap support SYNOPSIS
ssh-ldap-helper [-devw] [-f file] [-s user] DESCRIPTION
ssh-ldap-helper is used by sshd(1) to access keys provided by an LDAP. ssh-ldap-helper is disabled by default and can only be enabled in the sshd configuration file /etc/ssh/sshd_config by setting AuthorizedKeysCommand to ``/usr/libexec/openssh/ssh-ldap-wrapper''. ssh-ldap-helper is not intended to be invoked by the user, but from sshd(8) via ssh-ldap-wrapper. The options are as follows: -d Set the debug mode; ssh-ldap-helper prints all logs to stderr instead of syslog. -e Implies -w; ssh-ldap-helper halts if it encounters an unknown item in the ldap.conf file. -f ssh-ldap-helper uses this file as the ldap configuration file instead of /etc/ssh/ldap.conf (default). -s ssh-ldap-helper prints out the user's keys to stdout and exits. -v Implies -d; increases verbosity. -w ssh-ldap-helper writes warnings about unknown items in the ldap.conf configuration file. SEE ALSO
sshd(8), sshd_config(5), ssh-ldap.conf(5), HISTORY
ssh-ldap-helper first appeared in OpenSSH 5.5 + PKA-LDAP . AUTHORS
