I had to setup a Minolta BizHub 420 multifunction device on SUN Solaris 9 (UNIX), this is how I did it (of course, from the command line):
Download the Linux driver for the printer from here.
Install the driver (PPD file) by copying the file (KO500UX.ppd) to /usr/share/cups/model/, then restart CUPS:
cp KO500UX.ppd /usr/share/cups/model/
/etc/init.d/cups restart
You can now [...]
I was thinking, if you are making your own cert for internal use or testing, why make it for only a year?
Here’s how to make one that won’t expire for twenty years…
Generate a key:
openssl genrsa -des3 -out test.key 1024
Remove the passphrase:
cp test.key test.key.orig
openssl rsa -in test.key.orig -out test.key
Create the CSR:
openssl req -new -key test.key [...]
To change the settings quickly run the following from the command line and the restart networking:
echo 30 > /proc/sys/net/ipv4/tcp_fin_timeout
echo 1800 > /proc/sys/net/ipv4/tcp_keepalive_time
echo 0 > /proc/sys/net/ipv4/tcp_window_scaling
echo 0 > /proc/sys/net/ipv4/tcp_sack
Or change them in /etc/sysctl.conf for permanence after a reboot:
net.ipv4.tcp_fin_timeout = 30
net.ipv4.tcp_keepalive_time = 1800
net.ipv4.tcp_window_scaling = 0
net.ipv4.tcp_sack = 0
