HP ProLiant DL145 G3 Server - Manual (Page 52)

Using LO100 52
NOTE: When you use the CLP load command with TFTPD32, HP recommends using a 4-
second timeout and 10 retries.
NOTE: When using the CLP load command in Linux set the timeout to 15000000. The
firewall built into some Linux systems might not allow the TFTP server to send and receive
information. You might have to disable the firewall to allow these connections. If you are
experiencing firewall issues, change the firewall settings to allow connections on port 69 (the
default port for TFTP servers). See your firewall documentation for additional information.
Creating a certificate
LO100 requires a 1,024-bit DSA key stored in PEM (Base64-encoded) format to be located on a TFTP
server. For example, the following process uses Win32 OpenSSL, downloaded from the Shining Light
Productions website ( http://www.slproweb.com/products/Win32OpenSSL.html ), and the commands
issued in a DOS window to generate the certificate. To generate a certificate using Win32 OpenSSL:
1. Download Win32 OpenSSL.
2. Install and set up OpenSSL.
3. Using OpenSSL, generate a DSA parameters file:
openssl dsaparam -out server_dsaparam.pem 1024
4. Generate the DSA private key file, called server_privkey.pem:
openssl gendsa -out server_privkey.pem server_dsaparam.pem
5. Generate the DSA certificate (public key) file, called server cacert.pem:
openssl req -new -x509 -key server_privkey.pem -out server_cacert.pem -
days 1095
6. When prompted for a distinguished name, enter an appropriate domain name for the servers that
will be receiving the certificate.
7. After creating the certificate, copy it to a TFTP server that is accessible on the same network as
LO100.
Before importing a certificate or key, you must disconnect from any remote KVMS sessions. Importing a
key or certificate will disconnect your session and reset the LO100 processor. After importing a key or
certificate and LO100 confirms a successful upload, you must log back into LO100.
