I have an old last-gen PowerBook that lacks a DVD drive. Is it possible to install Ubuntu on it otherwise? It can't boot off USB but I can out it in target disk mode and have it show up on my other Mac as a FireWire drive. I've been looking online but haven't had any luck finding a tutorial for this.

That means G4 Powerbook right? Any reason you can't use an USB CD drive?

evol262 posted:Networkmanager isn't involved in NFS mounting. Are you sure this isn't a red herring? code:evol262 posted:_netdev ? code:evol262 posted:dmesg? Is this a gss failure because rpc-gssd isn't running but it's trying (and failing) krb5? Is rquotad running? Is the firewall blocking it? v3 or v4? evol262 posted:Is /misc/download created? If not, autofs may be failing to parse your entry for some reason.

Marinmo posted:With (and without) _netdev in fstab, systemd-analyze blame shows: Marinmo posted:In no particular order: v4(.1), rquotad not running, rpc-gssd is failing indeed because I didn't touch kerberos (no keytab). Honestly, it seems a bit convoluted having to set up Kerberos just for this - I might just skip it and let the current situation (slow fstab mounts) be if so. However, the firewall might be blocking it - I'll have to look into that. Marinmo posted:It isn't. It's weird though, because writing an autofs mount is just about the same as writing a fstab one ain't it? Seems hard to mess up somehow, but I guess we're all fallible. Will double check this too. Similar enough, I guess. But you can stop autofs and run the service manually in the foreground, which'll tell you if it failed to parse it. autofs always gets me, though, and it takes 10 tries to get it right.

evol262 posted:Well, the big question is: which auth providers do you need? Ex: Do you need openid, or did you use it as an example? It's easier to answer with specifics Point taken. The pieces of software installed so far use a variety of methods that don't completely overlap - OpenID and LDAP have the greatest number of "votes" and will cover about 90% of cases. So those are the obvious targets. Also seems worth mentioning that we don't currently have any in-house directory or the like, so one will have to be created from scratch and there's nothing to synchronise to. PS: had a OneLogin salesman call me up and do the hard sell on their product. Positive point is that they have an academic price so that may help.

Is there a reason you can't just put it in target mode and install to that? Assuming you can find a PPC distro. BSDs are probably better for all of that these days, and they have absolutely no problem installing to a secondary disk and putting the bootloader there.

That's what I'm asking - I've been looking for a way to install it to my PowerBook via target disk mode but I haven't seen anything for the PowerBook and Ubuntu. I'm hoping for Ubuntu because that's the server I'm developing on, but I can't find anything on the process. Are there tutorials?

Ubuntu may not even have PPC support. Debian does for sure. Boot in target mode. Attach the disk to a virtual machine (or boot the host from the installer image) and go from there. Warning: installing something which doesn't match the hosts architecture is gonna be interesting, and the Mac will need yaboot (I think -- it's been a long time). You'll need to attach it, partition it, mount, chroot, and debootstrap from another arch. I'll dig up docs tomorrow, but that string will get you started in google.

Hollow Talk posted:This is probably the best advice. Have a project. Make up a project. Think about things that would be neat, then see if you can implement them and get them to work. One of my more recent examples is that I wanted to parse an API each day at the same time, once a day (-> cron), for which I need to download its data (-> curl), parse it (-> json, sed), sort it (-> sort, uniq) output it (-> redirection, sed), glueing it all together (-> pipes) and putting all of it in a repeatable form that works both via cron and interactively (bash). The basic project required a whole bunch of useful knowledge, and I learned something more about BASH arrays in the process. On top of that, it now even pushes the data automatically to a git repository, so there are a bit of git, a watcher programme (via inotifywait) and a systemd service file involved as well. Many of these things are probably much more useful than installing Arch and wondering why your WLAN or backlight or whatnot is not working. Now I'm really curious what your project accomplishes. Care to explain?

Installing PPC from another arch: Read this, which is about ARM, but also applicable to PPC. Also read this Attach the disk from your powerbook in target disk mode. Partition it with an apple partition table, and create a bootstrap partition (if there isn't already one, which there probably is for OSX). Mount the partiitions. debootstrap it as the target. chroot in. debootstrap stage2. yaboot configuration/install. configure fstab (at a minimum).

Death Vomit Wizard posted:Now I'm really curious what your project accomplishes. Care to explain? Well, this parses a game API that returns killed spaceships as a set of structured JSON data (partially arrays, partially simple key:value pairs), so I have to construct the initial curl command that includes some time constraints in the url (past 24h), shiptypes etc. Since shiptypes are only present as id numbers, not names, I then use sed to filter (-n & p) and subsequently replace the few shiptype ids I care about with their name, while also parsing pilot name etc., which then get collated down to unique entries that contain shiptype, name and a few more things. These get put into git and go into a repository, which gives me a) a nice, browsable history of usage pattern for the shiptypes I am interested in and I can use that data for other things (such as using pivot tables in google docs to combine them into more meaningful sets and share them with others) and b) allows me through some further filtering to keep decent taps on how often certain shiptypes or pilots pop up etc. It's all hacky as hell, but works well and the basic system of API access -> filter/parse data -> output data makes it more universally useful. Basically, it's a silly contraption for the sake of gaming, but since I do all of this only as a hobby and as an amateur, that means it's as good a reason to try things as any.

I have rewritten parts of it in Racket (Scheme), and wrote a drop-in replacement for the json | json | sed part, and could do the sort | uniq step as well via filtering a list and then writing a function to sort strings alphabetically. But it ultimately boils down to  -- which would be different for the guy who asked about learning about system administration, I suppose, since there would be a greater incentive to continually make things work better (until management comes in and tells him that good enough is, well, good enough, etc.).

Installing a postfix, spamassassin, dovecot and getting it working properly can take a while (I will get around to setting up amavis and clamav on mine someday) If your CentOS instance meets the minimum requirements for Zimbra I'd suggest you just use Zimbra Open source edition which will set up everything for you and is very easy to use in comparison.

I remember when I set my up my mailserver that one of the two was a proper bother to set up, which is why I am running exim right now. That said, don't use exim, configuration is...not great.

With the thread's help, I was able to get the email to show up from the correct domain name. I did a number of things, I forgot what some of the things were, other things I blindly did without knowing exactly what they meant. In short, I shouldn't be administering a linux, but this is a hobby thing and the 5-10 users are all me, so it is good enough. I'll look into tying my domain into gmail, it'd be nice to not have to worry about it breaking or getting put on an RBL me-using-linux.gif

Since they ditched the free tier, Gmail is infrastructure for people with actual revenue streams. Which I assume your situation isn't since you're doing the janitoring as an after-beer activity. But if the 5-10 users are all you, Gmail for Work could be yours for the low low price of $50/year. VAGENDA OF MANOCIDE fucked around with this message at 22:53 on Jul 25, 2015 |

The "buy" vs. "make" decision is difficult. For personal projects I tend to go for "make" because its cheaper, and I wind up learning something new. On the other hand, I spend more time doing stuff to support the activity I'm interested in rather than the activity itself. I go to change a light bulb but wind up fixing the car. Anyways, I appreciate the help and the advice.

I don't like to make assumptions, and some users just need to send, not read, making "accessing their mail" a null argument.

Spamassassin works passably for me at work, but the thing that really cut the vast majority of spam we got was postgrey. Just remember to set the retry time to something short so you don't have to wait 5 minutes to reset a password or something.

Unless you want to have to fight to manage your system and get forced to use crappy UIs that barely work lest your config files get reset (and sometimes have it happen anyway for shits and giggles), all backed up by outdated documentation, avoid cPanel. Even if it weren't terrible, it's overkill for the specified needs.
