ViewSonic SC-T25 and certificates

ViewSonic SC-T25, VS, handles certificates, cert, for different applications in Base64-encoded DER format.

If You open the certificate file, with a simple text editor, it shall begin with "---- BEGIN CERTIFICATE ----" and end with "---- END CERTIFICATE ----" if it is the right format.

The most simple way to load the cert, is to use "Method 1".
Please note that You log in with the CLIENT, PC/Mac, user/password.

Another method is "Method 3". In this example I will load Citrix Intermediate Certs to the SC-T25 from a USB stick.

• Open up the VS and go to "Configuration"
• Login with Your Admin passsword
• Scroll down to "Console" and click starting a session
• Type 

$su 
Password: 

and the password for admin

• Insert the USB stick in the VS 
• The VS will confirm the insert and flash the path to the USB stick. For example

mounted /dev/sdb1 on /media/TEST (TEST is the label on the USB stick)

• Create the folder for Citrix Intermediate Certs (If not there)

mkdir -p /config/ctximdcerts

• And then copy from the USB stick

cp /media/TEST/*.cer /config/ctximdcerts

If You prefer to access the VS from an external client via ssh just type

ssh notouchadm@your.vs.IP

And enter your password (the one that you set when deploying the VS)

In some cases You need to convert the cert and if You are on Windows You find info here. On the VS, assume You have copied a CtxInt.cer certificate to the /config/ctximdcerts folder and want to convert it to the accepted VS format, type the following commands

$cd /config/ctximdcerts

$openssl x509 -inform der -in CtxInt.cer -out CtxInt.pem

The folder for regular certificates is 

/config/certificates
