|
|
I do quite a lot of software development (see http://stunnel.mirt.net/) on my Linode 160 running Debian sarge.
Usually I use strace(1) to diagnose some weird problems, but it doesn't work on Linode:
# uname -a
Linux linode 2.6.17-rc2-linode19 #1 Wed Apr 26 17:31:10 EDT 2006 i686 GNU/Linux
# strace ls
execve("/bin/ls", ["ls"], [/* 14 vars */]) = 0
file1 file2 file3
#
I guess ptrace(2) is disabled for some reason. Can you enable this functionality? |

You're on one of the few hosts that's running an old kernel with this bug. Submit a support ticket to be moved to a different host, where strace will work.

| Are there any drawbacks of moving to another machine? Will I keep my IP address? What is the expected downtime? |

Everything moves with you (IPs, disk images, configs, etc). You can press The One Button to start the migration when you're ready (after we configure it). I'd expect a few minutes per GB to transfer your disk images across.
