SSH postponed authentication (publickey)Posted: 25 January 2011 Filed under: security | Tags: security Leave a comment
An interesting syslog message!
sshd[xxx]: 'Postponed publickey for oracle from ::ffff:22.214.171.124 port 9264 ssh2'
As Tom explains,
ssh is just stepping through the client-configured authentication types (enabled in either ssh_config or ~/.ssh/config) and trying them in turn, but acknowledging that a publickey was presented, and postponing its use until after trying the first auth type.
Split a file across multiple CDs or DVDs on LinuxPosted: 13 January 2011 Filed under: productivity, ubuntu | Tags: command line Leave a comment
Okay, so you very likely have the ‘split’ utility installed (it’s in the GNU coreutils package, so… very likely). If you want to burn a file to multiple media, but you don’t have kdar installed on your desktop… don’t worry about it. Just open a terminal and do:
$ split --bytes=600MB --numeric-suffixes filename.zip filename_part_
In my case, I have a 2.8GB file, but I only have 700MB CDs on hand for my burner. So this command will ensure that I get several 600 “megabyte” (1000 bytes * 1000) pieces, named “filename_part_00,” “filename_part_01,” and “filename_part_02,” et cetera.
