Full Discussion: ssh very slow
Operating Systems Solaris ssh very slow Post 302270748 by reborg on Monday 22nd of December 2008 06:56:05 PM

There are a few things which can cause this, all of which have the same initial response delay when connecting.

1. DNS (on the system you are connecting to) as already mentioned, use of the ipaddress does not preclude this possibility, because if UseDns is set the server will attempt to lookup the client before allowing the connection.

2. Netmasks. If the netmask is incorrect on the server or client it will take some time to figure out the correct routing.

3. Network autonegotiation issue, if one or other party ends up half-duplex you will see similar problems.

ssh-ldap-helper

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 .
