| 00:00 | <@Consul> | You have to chown it to root, I think. |
| 00:00 | <@C_tiger> | Ok, I did that. |
| 00:00 | <@Consul> | Then give it user execute privs. |
| 00:00 | <@Consul> | then it's just chmod 0755 |
| 00:00 | <@Consul> | Typically. |
| 00:00 | <@Consul> | YMMV |
| 00:00 | <@C_tiger> | but it still is spitting out permission denied. |
| 00:00 | <@Consul> | Really? |
| 00:00 | <@Consul> | Distro? |
| 00:01 | <@C_tiger> | um... I'm not sure, it's on a file server. |
| 00:01 | <@Consul> | Hrm... |
| 00:01 | <@C_tiger> | I have a script that I want to cronjob to move files over on a regular basis. |
| 00:01 | <@C_tiger> | but I need root permissions to access the file it wants to move. |
| 00:02 | <@Consul> | Does cron run as its own user? |
| 00:02 | <@Consul> | Oh, I see. |
| 00:02 | <@Consul> | Nevermind.. |
| 00:02 | <@Consul> | Is the script also chown-ed to the root group? |
| 00:02 | <@C_tiger> | and I can't seem to elevate the script to have permissions to do that. |
| 00:02 | <@C_tiger> | yep. |
| 00:02 | <@Consul> | chown root:root filename |
| 00:02 | <@C_tiger> | maybe root:root |
| 00:03 | <@Consul> | Man, my sysadmin skills are so out of practice... |
| 00:03 | <@Consul> | But... |
| 00:03 | <@C_tiger> | hmmm... root:root works. |
| 00:03 | <@C_tiger> | Ok, I guess that was it. |
| 00:03 | <@Consul> | Ah, okay. |
| 00:04 | <@Consul> | I don't have to go off on my next flight of fancy. :-) |
| 00:10 | <@ToxicFrog> | I note that that's not quite what you asked for, although if it works now, it probably is what you actually needed. |
| 00:10 | <@C_tiger> | ... |
| 00:10 | <@ToxicFrog> | root:root mode 755 is "owned by root; in group root; root can read, write and execute; users in group root can read and execute; everyone else can read and execute" |
| 00:10 | <@ToxicFrog> | But if, say, bob runs it, it'll run as bob. |
| 00:11 | <@C_tiger> | I did +s also |
| 00:11 | <@ToxicFrog> | If it needs to run with root permissions even when bob runs it, the term you're looking for is setuid, which is...yes. |
| 00:11 | <@C_tiger> | but I couldn't make +s work which is why I came here... because apparently you need root:root and not just root. |
| 00:13 | <@ToxicFrog> | That does strike me as odd |
| 00:15 | <@C_tiger> | nevermind, no, it doesn't run as bob |
| 00:15 | <@C_tiger> | -rwsr-sr-x 1 root root 304 Nov 10 16.:07 cwang.bash |
| 00:16 | <@C_tiger> | what's wrong? |
| 00:16 | <@ToxicFrog> | What happens when you try? |
| 00:16 | <@C_tiger> | it runs but it gets the permission denied message. |
| 00:16 | <@C_tiger> | when it tries to copy. |
| 00:17 | <@C_tiger> | cp: cannot open `[file]' for reading: Permission denied |
| 00:17 | <@ToxicFrog> | But as root, you can read it? |
| 00:17 | <@C_tiger> | yep. |
| 00:17 | <@C_tiger> | sudo ./cwang.bash works just fine |
| 00:17 | <@ToxicFrog> | *flail* |
| 00:17 | | Vornucopia is now known as Vornicus |
| 00:19 | <@C_tiger> | Vornicus? |
| 00:19 | <@C_tiger> | can you save me? |
| 00:19 | < Vornicus> | C_tigericus? |
| 00:19 | < Vornicus> | No. |
| 00:19 | | * C_tiger sobs. |
| 00:19 | < Vornicus> | I don't know how to do setuid. |
| 00:20 | < Vornicus> | C_tiger: Looking at your permissions line, I see s s x |
| 00:20 | < Vornicus> | You have to be in the root group to run it? |
| 00:20 | <@C_tiger> | actually you have to run it as root. |
| 00:20 | <@C_tiger> | I'm in the root group and I can't even run it. |
| 00:20 | <@ToxicFrog> | s is setuid/setgid |
| 00:20 | < Vornicus> | okay. |
| 00:20 | <@ToxicFrog> | Ie, it inherits that effective group or user id when run, regardless of who runs it |
| 00:21 | < Vornicus> | Right, run it /properly/, that is |
| 00:21 | <@C_tiger> | wikipedia says that some file systems ignore setuid for shell scripts. |
| 00:21 | <@ToxicFrog> | At least in theory, a file that's rwsr-sr-x root:root will have an effective uid and gid of root when run even if bob runs it |
| 00:22 | <@Consul> | I would imagine some servers could have security set up in such a way that setuid doesn't work? |
| 00:22 | <@Consul> | Considered a security risk? |
| 00:22 | <@C_tiger> | yeah. |
| 00:22 | <@ToxicFrog> | Usually that's handled by dropping the setuid and setgid bits when the permissions change |
| 00:23 | <@ToxicFrog> | So you can, say, either make your script setuid self, or give it to root, but not make it setuid root |
| 00:23 | <@C_tiger> | Hmmm... ok, so how do I do this? |
| 00:23 | <@C_tiger> | can I put sudo in a bash script and not provide a password? |
| 00:24 | <@ToxicFrog> | Not unless the system is set up to let you sudo without a password |
| 00:24 | <@C_tiger> | which it isn't. |
| 00:24 | <@ToxicFrog> | I don't see how ignoring setuid on shell scripts gives any benefit, though |
| 00:25 | <@C_tiger> | I guess if you accidentally give w permissions to someone, suddenly they have superpowers. |
| 00:25 | <@ToxicFrog> | Right, but the correct answer there is "so don't do that, then" |
| 00:26 | <@ToxicFrog> | Giving users write permission to, say, /etc/passwd, you're boned whether setuid is allowed on shell scripts or not |

| 00:35 | < Vornicus> | or rather, root gets a crontab. |
| 00:35 | <@C_tiger> | so I just sudo - and then crontab right? |
| 00:35 | <@C_tiger> | right. |
| 00:37 | <@C_tiger> | or su - and apparently I can't do that. |

| 19:52 | < Emma> | how are you? |
| 19:55 | <@AnnoDomini> | Good. |
| 19:57 | < Emma> | thats good. school is so boring! im in studyhall. i jsut got done watching Twilight trailers. I CANT WAIT for the movie to come out |
| 19:57 | <@AnnoDomini> | Oh, god. Twilight as in that vampire stuff when they sparkle in daylight? |

| 19:58 | <@AnnoDomini> | Not to sound rude, but from what I've read about it, it's... bad. Very bad. Horribly bad. |
| 19:58 | < Emma> | its a good book |
| 19:58 | <@AnnoDomini> | How old are you? |
| 19:58 | < Emma> | 14 |
| 19:58 | <@AnnoDomini> | Figures. |
| 19:59 | < Emma> | almost everyone in my high school is reading it now |

| 19:59 | < Emma> | no thanks. |
| 20:00 | <@AnnoDomini> | Suit yourself. |
| 20:00 | < Emma> | twilight will kick harry potter's ass once again! (sorry, i act like a little kid when it comes to things i like |
| 20:01 | <@AnnoDomini> | Harry Potter was tolerable. Can't say the same of this thing. |
| 20:02 | < Emma> | i like the movies, i cant stand the books though |
| 20:04 | <@AnnoDomini> | And why is that? |
| 20:04 | < Emma> | im not sure. the harry potter books just bore me |
| 20:04 | < Emma> | i tried reading it this year and i got like the first chapter and stop reading. it was so boring |
| 20:05 | <@AnnoDomini> | Whatever HP books are, they aren't boring. I should know - I tried to read the unabridged version of Pride of Prejudice. |
| 20:05 | <@AnnoDomini> | Now that's boring. |
| 20:05 | <@AnnoDomini> | s/of/and |
| 20:05 | < Emma> | lol |
| 20:06 | <@AnnoDomini> | After fifty pages of nothing fucking happening, I couldn't go on. |
| 20:06 | < Emma> | Midnight Embrace and Full Moon Rising are some more really really good vampire books i like. FMR has a sex scene in each chapter! i cant wait to buy the book! |
| 20:07 | <@AnnoDomini> | You read anything without vampires in it? |
| 20:07 | < Emma> | i read The Outsiders |
| 20:08 | < Emma> | ive read over 2000 books in 10 years. i love reading |
| 20:08 | <@AnnoDomini> | 2000 books? |
| 20:08 | < Emma> | 2,000 |
| 20:08 | < Emma> | yeah |
| 20:08 | <@AnnoDomini> | That'd be 200 books per year. |
| 20:08 | < Emma> | i spend all my free time reading and riding horses |
| 20:08 | <@AnnoDomini> | !roll 365/200 |
| 20:09 | <@AnnoDomini> | That's 1.85 days per book. |
| 20:09 | <@AnnoDomini> | I'm not certain I want to believe that. |

| 20:10 | <@AnnoDomini> | About as much as any 14 year old kid? |
| 20:10 | < Emma> | i skip school occasinaly. and i never have home work so... maybe like a couple mintues more XD |

| 20:16 | <@AnnoDomini> | Good thing there are still kids who read books. Too bad that sometimes, their taste is just so bad. |
| 20:24 | <@C_tiger> | It's the ADD society. |
| 20:24 | <@AnnoDomini> | Advanced Dungeons and Dragons? :P |
| 20:24 | <@C_tiger> | Attention Deficit Disorder. |
| 20:24 | <@AnnoDomini> | I know. :P |
| 20:25 | <@C_tiger> | They can't invest the time to read a book where the main draw comes from character development or sweeping themes. |
| 20:25 | <@AnnoDomini> | Hmm. Explain. |
| 20:26 | <@C_tiger> | I was reading To Kill A Mockingbird at 14. It was tough book to understand but deeply powerful. That said, there's no ACTION. |
| 20:27 | <@AnnoDomini> | I see. |
| 20:27 | <@C_tiger> | Good vs Evil books are easy reading, it's easy to know who to cheer for, there's constant action, people are thrown from cliffs or dodging bullets. |
| 20:29 | | * AnnoDomini nods. |
| 20:30 | <@C_tiger> | These days, the kids don't read the sort of novel which just paints a portrait of a historical period, involve a single deeply conflicted character, even the standard coming-of-age (what's the german word for this again?) story is now rewritten so the actual development happens quickly and then the hero can go slay a few monsters. |
| 20:30 | <@AnnoDomini> | Bildungsroman. |
| 20:32 | <@C_tiger> | Right. |
| 20:32 | <@C_tiger> | I honestly can't see your typical teen voluntarily reading Great Expectations these days. |
| 20:32 | <@AnnoDomini> | One of my favourite books was just that. The Power of One. |
| 20:57 | <@McMartin> | C: I have to admit, many aspects of the craft of novel-writing did not evolve to something I find pleasant to read until the mid-20th century, if then. |
| 20:57 | <@McMartin> | With a few other ones. |
| 20:57 | <@McMartin> | (Hilariously, the fact that, for instance, Bram Stoker's Dracula is all 19th Century and otherwise unreadable gets a pass precisely because it is epistolary) |
| 21:01 | | * TheWatcher readsup, notes that To Kill A Mockingbird might have a good story in it somewhere. If it did, it was utterly annihilated by his GCSE english lit course (ditto Cider with Rosie, and The Scottish Play, Romeo and Juliet, and a few other of the Bard's works) |
| 21:08 | <@AnnoDomini> | Huh? |
| 21:10 | <@McMartin> | Great Gatsby still more or less holds up, even if it is "lol obnoxious rich people wrecking their lives" |
| 21:11 | <@McMartin> | Moby Dick isn't *bad* if you skip the five+ chapters of "and now, a cetology text." |
| 21:11 | <@McMartin> | A lot of the things we often now consider flaws even in fanfic are rampant in early 20th century-and-before writing. |
| 21:12 | <@McMartin> | Hemingway is... interesting, but I personally consider his style kind of a failure |
| 21:12 | <@McMartin> | However, anyone writing screenplays needs to read and study his technique carefully. |
| 21:12 | <@McMartin> | (Most of his books we get no internal monologue; I think this doesn't work on the page, but for film you don't *get* those) |
| 21:14 | <@AnnoDomini> | (It's a necessity in PbP games with PvP enabled. :P) |
