Recursive, Incremental FTP

Thursday, April 14, 2011 

Looking for a way to transfer an entire website, including subdirectories, from one server to another directly, I found this summary http://www.cyberciti.biz/tips/linux-download-all-file-from-ftp-server-recursively.html of a great tool: NCFTP.

The client supports recursive “get” and “does the right thing.” It silently handles broken symbolic links, downloads all the files in the source directory including subdirectories, and even better, smartly does an incremental update on repeat saving a lot of time, bandwidth, and tedium.

Great utility that makes systems admin just a little bit easier. From now on, part of the default install.

Linux 342

Wednesday, August 15, 2007 

An IBM 342 with a ServeRAID 4lx is a fine machine, but getting Linux to install is less the effortless. Emacs!

I’m trying to get zoneminder to work on this very nice IBM 342 with a serve raid card and some good drives and 3 video capture cards. The thing should be able to capture 12 streams of video simultaneously, or 6 at full 30FPS. But getting Linux variants to properly recognize the serveraid card is a challenge.

The Mandrake LiveCD install works great on IDE systems, no problem at all. But it doesn’t see the serveraid, so that one was out. Gentoo saw the serveraid card, and since video capture and real time analysis is one of those things that would be good to do fast, the gentoo optimization scheme seemed promising, but it wasn’t. Just a miserable series of failed compiles and fixes that went on endlessly.

So from there to Debian, which is very nice and since it is the parent of Ubuntu and there’s an Ubuntu package and Carolyn loves Ubuntu, that seemed worth a shot. It does see the Serveraid, but there seems to be a bug in the IPS.o driver which reared it’s irritating head during package installs causing hangs, even after I updated the firmware to 7.12.12.

So that was out. On to a distro officially supported by IBM: Suse. That installed great, easy no problem, detected all the ADCs on the capture cards and everything. Very easy to install, but there are some weird bugs with ffmpeg that hung the compile of Zoneminder. It descended into another endless series of patch and edit and retry effort to get through the compile….

Then I saw that Fedora 7 has an RPM in the main distro for ZoneMinder. It is officially supported by IBM and seems rock solid. So far the network install has gone well – the install CD is only 7.71 MB (!) and it seems tentatively promising… it’s on the “Starting install process” screen, which is supposed to take several minutes. As it may need a few GB of data, I’ll give it some time. Unfortunately Fedora doesn’t support CD installs and the 342 has a laptop style CD-ROM drive, so doing a DVD install is out of the question. Network installs are efficient if you only have to do them once, but the retry is all penalty download.
