Because I am feeling accomplished, and because I also want to avoid my physics homework. I think I’ve got a pretty good system working for CS137 (and the UW CS servers) now. I’ve got: sshag working, so I don’t have to eval `ssh-agent` && ssh-add each time I open a new screen session a modified […]
Note: This is a personal VPN, so I just used static keys. A general guide to getting OpenVPN set up is available on the OpenVPN website, but this guide is targeted at CentOS 5 on an OpenVZ VPS. This guide should be usable in other RH derivatives without much (any?) modification; and with slight modifications […]
Note to self: When configuring iptables, don’t copy + paste /sbin/iptables -F /sbin/iptables -P INPUT DROP <bunch of other commands> into bash. I had A Bad Time.
tl;dr – Either a plesk update or CentOS update borked an OpenSSHd install such that the sshd_config was pointing to an sftp-server that didn’t exist where it was looking for it, but existed in two other locations. Fix was to update the sshd_config while investigating the possibility of removing the duplicate install.
I’m moving a VM from my own server to EC2. I’ve got $50 worth of credit from a Redhat event, so I would like to make use of that. (That, and my AWS account existed before the free tier was introduced, so I’m not eligible for that.) That said, I want to make that credit […]
I’m in the middle of trialing EC2, and I’m using the official Fedora 17 images kindly provided by the community. They make a great starting point, because I can then install my needed software. Some of which, though, I consider absolutely crucial. So far, I’ve need to install vim, less, rsync and screen. I can […]
Another thing from the xen-users mailing list: Apparently the way to specify the dom0 RAM at boot in Xen has changed. You should now specify the maximum memory – dom0_mem=2G,max:2G instead of dom0_mem=2G. Also, a new addition to the Xen Best Practices suggests preventing Xen from auto-ballooning the dom0 memory down by changing autoballoon in […]
While trying to diagnose a problem with my VMs (namely, why starting a fedora 16 based vm fails to bring up the network connection), I ran into a strange issue – on my dom0 and some of the domUs, logrotate hasn’t been running, leaving me with insanely long logfiles! So I set out trying to […]
Before I upgraded my dom0 to Fedora 16 (and by association Grub2), I had the dom0 memory limit fixed as an argument in grub.conf. When I upgraded to Grub2, I initially added it manually to the Xen boot command line, but eventually stopped doing that. Today while looking through the xen-users list, I found an […]
So, I’ve wiped my test system with the intention of doing a tutorial on installing F16 + Xen. As part of this, I looked into installing a F16 domU with virt-install. When I tried it previously, I ran into this bug, and I ended up having to vnc into the dom0 and use virt-viewer to […]
