How do I copy a file with a colon punctuation (:) name in it. When I type the following command to copy “file:name.txt” to a remote host called server1:

scp file:name.txt user@server1:/path

I get the following error:

ssh: Could not resolve hostname s: Name or service not known

How do I copy file with scp or rsync with a colon in it?

OpenBSD version 4.5 and above made changes in kernel which prevents booting OpenBSD using KVM technology. OpenBSD 4.4 runs with mbbios enabled. However, due to some sort of bug in KVM it does not boots. The workaround is to disable mpbios. This may or may not happen with your installation.
