untrusted SSL certificate, refer to the notes below for how to work around this for various
browsers.
When an SLB is configured with a SSL certificate that is either a wildcard certificate or associated
with a specific name, in order to establish a Web SSH or Web Telnet session to the SLB unit, the
unit must be able to successfully perform a reverse lookup on any IP address to which Web SSH
or Web Telnet requests are sent. For example, if a unit is configured with a SSL certficate for the
name "slbXYZ.lantronix.com", and the unit website is being accessed in a browser with "https://
slbXYZ.lantronix.com", the unit needs to be configured with a name server that will allow the unit to
perform a reverse lookup on the IP address associated with slbXYZ.lantronix.com. Failure to
perform a reverse lookup on a name may result in name mismatch errors in the browser when it
attempts to open the Web SSH or Web Telnet window.
If you are unable to connect to a Web SSH or Web Telnet session for a reason other than a
browser SSL certificate issue, restarting the SSL server on port 8000 may resolve the connection
problem. This can be done by restarting the web server (with the CLI command "admin web
restart") or by disabling both Web SSH and Web Telnet on the
web page,
and then re-enabling them.
Chrome
- For the greatest ease of use with Web SSH and Web Telnet, when the SLB web
server is using a self-signed SSL certificate, use the Chrome browser. When the user accepts
the self-signed SSL certificate in the browser for the primary SLB website, the self-signed SSL
certificate is accepted for all ports - including port 8000 - for the SLB website.
Firefox
- When accessing the SLB website with Firefox, and when the SLB web server is
using a self-signed SSL certificate, accepting the self-signed SSL certificate in the browser for
the primary SLB website will only accept the certificate for port 443. It will not accept the
certificate for port 8000. This may result in a popup being displayed in the Web SSH or Web
Telnet window indicating that the browser needs to accept a certificate. To accept the self-
signed certificate for port 8000, go to Firefox -> Options (or Preferences) -> Advanced ->
Certificates -> View Certificates -> Servers, and add an exception for the SLB IP address or
hostname, with port 8000.
Internet Explorer
- When accessing the SLB website with Internet Explorer, and when the
SLB web server is using a self-signed SSL certificate, Explorer will grant access to the Web
SSH and Web Telnet terminals if (a) the host name or common name in the self-signed
certificate matches the name (or IP address) being used to access the SLB website, and (b)
Explorer has imported and trusted the self-signed certficate. A custom self-signed certificate
with the SLB name can be generated via the
web page or the admin
web certificate custom CLI command.
Once the SLB web server has been configured to use the custom self-signed certificate, follow
these steps for Internet Explorer to trust the custom certificate:
In Internet Explorer, browse to the SLB website whose certificate you want to trust.
