Login problems

User is waiting up to 60 seconds before login is accepted or denied

other factors: authentication is set to ‘both’ or ‘RADIUS’. User has entered username and password, and has pressed <return> key.

•check RADIUS configuration of primary and secondary authentication/accounting hosts specified, and you have retry and timeout values greater than the default, the unit will be spending time trying each of these hosts and keeping the user waiting.

•adjust RADIUS configuration: specify just one host, reduce timeout and retry values to the default or less than default.

•when connecting using a reverse ssh connection, a delay of about 10 seconds for SSH version 1 will be experience. A delay of 20 seconds for SSH version 2 will be experienced. These delays are due to the negotiation of a secure LAN connection. This involves the exchanging of encryption messages to establish a secure communication.

You cannot progress beyond the ‘login’ and ‘password’ prompts (when authentication is set to either ‘both’ or ‘RADIUS’)

•check the setting of ‘account_authenticator’ flag is the same in the unit and the RADIUS host; either they should both check or both ignore the authenticator field. If you are not sure, change the setting in the unit; see if this fixes the problem.

•on the RADIUS host check the secret (password); you should see it displayed in clear text in the RADIUS clients file. If you are unsure whether it is the same secret which you entered in the unit, go to the unit and re-enter a new secret.

•on the RADIUS host check there is only one entry for a particular user; do not have multiple entries of the same username (although passwords may be different).

You cannot obtain a login on any of the front-mounted ports

•Connect via the Admin port and check the settings of the front-mounted ports; they have probably been set to ‘direct’ or ‘silent’ telnet/rlogin.
