I was getting a lot of “Wide character in print” errors from a perl script. A little googling led me to this page and the solution. In short, I was printing unicode characters to an I/O layer that did not support unicode, hence the error. Adding a call to binmode solved this.
example:
open(FILEHANDLE, “>$filename”);
binmode(FILEHANDLE, “:utf8”);
printf(FILEHANDLE, “Hello World!n”);
These are some handy Linux system utilities:
I recently acquired a Sun Netra T1 105 to play with. A few eBay purchases later and I had 512MB of RAM and a couple of 9GB Compaq SCA drives installed. Debian is pretty well supported for sparcs so that’s what I chose to install. The install was done over serial console as this box doesn’t have keyboard or framebuffer support.
After netbooting a kernel image following the instructions here the rest of the install was just a normal Debian install.
After the install and rebooting the machine I was greeted with a trap 3e error and an ok prompt. From googling it looks like this is a common problem with several possible causes. The fix that worked for me was to put a small script in nvram (I LOVE real server-class hardware).
Note: line 3 is “boot” followed by a Ctrl-c to get back to the ok prompt
For some reason on this machine I had to do a probe-all followed by a probe-scsi for it to pick up the SCSI drives reliably after poweron.
The combination of a LOM (Lights Out Management) module and OBP (Open Firmware Prom) make for easy server management.
This website is now hosted on this machine in my basement.
