OpenSolaris FIX: Server refused to allocate pty (SSH)

May 11th, 2010 5 comments

Just upgraded a friends OpenSolaris boxen to SNV_134 (latest available from the OpenSolaris dev repository) and after rebooting we realised we couldn’t SSH into it.

Server refused to allocate pty

DOH! This is caused by a known bug that has been around for a few builds now.

You’ll need to modify /etc/minor_perm and add the following to the bottom of the file.

clone:ptmx 0666 root sys

And what happens if your terminals don’t accept keyboard input? You could drop back into the shell *or* be lazy like me, find gText editor in your Accessories, add it to the panel and change the properties to run it as a privileged user:

pfexec gedit %U

Then run the file, open the /etc/minor_perm file, save and reboot. Make sure you change back the shortcut path 🙂

Next generation Linux file-systems

November 5th, 2009 No comments

If you’ve been reading this blog a couple of things are clear, I don’t like Apple much and I have a soft spot for file-systems. An article was posted on the IBM DeveloperWorks site that covers two file systems; NiLFS(2) and exofs that has some great information about these two beasts.

Linux® continues to innovate in the area of file systems. It supports the largest variety of file systems of any operating system. It also provides cutting-edge file system technology. Two new file systems that are making their way into Linux include the NiLFS(2) log-structured file system and the exofs object-based storage system. Discover the purpose behind these two new file systems and the advantages that they bring.

Read the full article on the Next-generation linux filesystems, there was an article on LWN.net a few years back discussing the (then emerging) Btrfs and NiLFS and how things may pan out. I’m quite happy and content with ZFS but in either case it’ll be interesting to see how all three go.
