[sage-support] Sage server on a gentoo system
Does anybody have some hints on how to get a sage server up and running on a gentoo system? I have never tried it on any system, and the guidelines in the sage docs do not readily apply in this case. I presume I need to configure apache somehow, create subdirectories with the sage code, and ??

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, I don't think you need to do anything special. Just install sage the normal way (either from binaries or building from source), then run sage -notebook This can be run either as root or as a normal user (probably preferable). You do not need to install or configure apache, since sage comes with its own web server, twisted. It's probably a good idea, before you start a notebook, to type notebook? in sage and read the documentation. BTW, for mysterious reasons I can only get sage-2.10.2 and earlier to serve the notebook for outside connections; I've been having trouble with the newer versions. So if you cannot get sage-2.11 or so to work, you might want to try an earlier version.

Namely, you now *must* do sage -c "notebook(address='the.address.of.your.computer')" in order to have the notebook listen on anything other than localhost. In 2.10.2 and some earlier versions we temporarily had a *bug* that made the notebook listen on all addresses by default. This is less secure since people using the notebook locally are exposing themselves to the possibility of somebody not logged into their computer attempting to hack into the notebook.This behavior is documented a tiny bit in the address section of "notebook?", though it's not very detailed! address-- (default: 'localhost'), address to listen on By the way, if you will have multiple untrusted users you should users the accounts= option. william --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~--~~~~--~~--~--~---

That *should* work, at least on most machines it works to give the hostname. That it doesn't on yours means there is something perhaps slightly unusual about your network's configuration.

[sage-support] bug in DirichletGroup?

Yep, that's my fault.

[sage-support] Doctesting external files
Hi, I'm using Sage to doctest the code I've written for a new external project that I started. Currently I have to put ">>> from table import *" at the top of each of my doctest blocks. I don't want to have to add and remove this line before each release especially as my code base enlarges. I'm requesting that the Sage frontend to Python's doctest framework be made more intelligent when dealing with external files and projects. For example, maybe if a file is outside the Sage code base, then the frontend would add "from blah import *" to each doctest block automatically where blah is the file name minus the filetype identifier.
