I realized a few of my log files were growing unusually large, and even worse, logrotate was skipping them. I took a look in logrotate.d and straight away realized why: I had created silly names for the log file. logrotate look for .log files, but I had specified mine as .log – e.g. kelvinism_access_log. I was as familiar with logrotate when I set up the domains, so set forth to get them in the rotation.
Read moreI’m not impressed too often with much software, especially the closed source kind. I find a leaning preference to all things FOSS. If I had a million dollars, I’d likely spend all day contributing to all the projects I wish I had time to contribute to. Regardless, there are a select few closed-source products that I believe are truly excellent. I mean, the type of software where you aren’t asking “I wish this could do this” and start asking “I wonder what else this can do.”
Read moreI’ve been side-tracked on another little project, and keep coming back to NetFlow. For this project I’ll need to access NetFlow data with Django, but this is a bit tricky. First, I’m sort of lazy when it comes to my own project; maybe not lazy, I just like taking the most direct route. The most up-to-date NetFlow collector I noticed was flow-tools, and there is even a switch to export the information into MySQL. Sweet! However, I wanted to insert the flows into MySQL automatically, or at least on a regular basis. I first started writing a python script that would do the job, but after a few minutes noticed flow-capture had a rotate_program switch, and started investigating. Since I somehow …
Read moreI’ve evaluated Zenoss before, but forgot the default password, and searching for it didn’t come up with anything quickly. I tried everything under the sun: password, 1234, admin, God, Sex, but alas, grep to the rescue:
kelvin@monitor:/usr/local/zenoss/zenoss/etc$ grep admin * hubpasswd:admin:zenoss Update: it is listed on page 4 of the Admin PDF :)
Read moreMy little server doesn’t have a cdrom, but I didn’t want to actually run ESX from a USB (i.e. esx-on-a-stick). Here are my notes of configuring a flash disk to boot the ESX installer (so you can install it onto a local disk). For this demo, my USB is /dev/sdb
Install the syslinux utils to your computer (apt-get install syslinux mboot) Install the MBR sudo install-mbr /dev/sdb Copy all the files from the ISO to your fat32 formated partition Install syslinux sudo syslinux /dev/sdb1 Move isolinux.cfg to syslinux.cfg, and try booting. If it doesn’t work, edit syslinux.cfg says something like: default menu.c32 menu title ESXi Boot timeout 100 label ESXi menu label Boot VMware ESXi kernel mboot.c32 …
Read moreI rank OSSEC as one of my favorite pieces of open source software, and finally decided to play around with it more in my own free time. (Yup, I do this sort of stuff for fun). My goal was quite simple: send syslog packets from my Cisco to my “proxy” server, running OSSEC. I found that, although OSSEC supports Cisco IOS logging, it didn’t really work. In fact, I couldn’t find any examples or articles of anybody actually getting it to work.
Read moreAs you can tell from reading some of the other pages, I like Linux and open source. But I also like to answer the question “what if…” This post is my [brief] run down of answering “what if I could run Django on Server 2003 with SQL Server and IIS.” Why, you may ask? To be honest with you, at this point, I don’t really know. One of the deciding factors was seeing that the django-mssql project maintains support for inspectdb, which means I could take a stock 2003 server running SQL Server, inspect the DB, and build a web app on top of it. The Django docs offer a lengthy howto for using Django with IIS and SQL Server, but the website for PyISAPIe seems to have been down for the …
Read moreI’m always forgetting the exact string to enter at the CLI for updating the IOS on a wireless Cisco AP, so I’ll just put it here to end my future searches:
Chimp# archive download-sw /force-reload /overwrite tftp://192.168.83.150/c1100-k9w7-tar.123-8.JEC1.tar 192.168.83.150 obviously being your tftp server, and the .tar file sitting in the root of the tftp server.
I suppose if you wanted to backup your IOS you could do something along the lines of:
Read moreBacking up your Openfiler box to S3
While I don’t think most pople would expect to backup their entire NAS/SAN to Amazon’s S3, there might be a few very crucial things you need to backup.
I’ve seen an implementation using Ruby and s3sync – something that I do on my server – but I’m trying to migrate everything to Python. Although there are a lot of great tools out there for S3, many of them Python-based, I wanted to do one thing and do it well: have one complete full backup available, and using as little bandwidth as possible. In these regards Duplicity would work well, except I wanted the ability to browse the S3 store using any other tool.
Read moreUsing TimeVault with a shared drive as a backend is actually quite easy, but it does require a few special things setup. Note: this is gonna be a brief summary.
Install samba-tools, smbfs…
sudo apt-get install samba-tools smbfs A lot more other stuff may install as well.
Create a script that mounts your samba share. You could also do this in fstab, but I tend to suspend my laptop when I come home, and I like clicking buttons.
