| 21:06 | < abudhabi> | Anyone know how to use symlinks with lighttpd? |
| 21:07 | < abudhabi> | I'm trying to have a symlink in /var/www pointing to elsewhere (in my home directory). Trying to access it in the browser yields 403. |
| 21:11 | <&[R]> | Does the user lighthttpd runs as have access to your homedirectory (and the subdirectory)? |
| 21:13 | <&[R]> | You might be better off giving your user write access to a directory in /var/www/ and symlink from your home directory to the one in /var/www/ |
| 21:14 | | Kindamoody|afk is now known as Kindamoody |
| 21:18 | < abudhabi> | How do I check if it does have access? |
| 21:19 | <&[R]> | [rstamer@disc0 ~]$ sudo su - nobody |
| 21:19 | <&[R]> | -sh-5.1$ DIR=~rstamer/public_html; while test "$DIR" != /; do ls "$DIR" &>/dev/null && echo "G: $DIR" || echo "B: $DIR"; DIR="$(dirname $DIR)"; done |
| 21:19 | <&[R]> | B: /home/rstamer/public_html |
| 21:19 | <&[R]> | B: /home/rstamer |
| 21:19 | <&[R]> | G: /home |
| 21:20 | < abudhabi> | I want the stuff to actually be in the folder where it is, and not in /var/www, because it's in part of my syncthing setup. If I move it out of there, it won't be synced. |
| 21:20 | <&[R]> | Assuming `nobody` is the httpd user |
| 21:20 | <&[R]> | It's more likely `http`, `httpd`, or `www` |
| 21:22 | < abudhabi> | Hmmm. www-data? |
| 21:23 | < abudhabi> | Yes. |
| 21:23 | <&[R]> | It lists "G" for all the directories? |
| 21:23 | <&[R]> | Can you `cat` the file? |
| 21:24 | < abudhabi> | `sudo su - www-data` spits out 'This account is currently not available.' |
| 21:25 | <&[R]> | sudo -u nobody /bin/bash -l |
| 21:25 | <&[R]> | Try that instead |
| 21:27 | < abudhabi> | Hmm. It's telling me that '/.bash_profile: Permission denied' but succeeds in giving me a different prompt now, anyway. |
| 21:28 | < abudhabi> | I'm guessing this confirms lack of access. |
| 21:28 | <&[R]> | Nope |
| 21:28 | <&[R]> | That's unrelated |
| 21:31 | < abudhabi> | B: dirname: missing operand Try 'dirname --help' for more information. |
| 21:31 | < abudhabi> | I'm not sure I am running the command properly. Not sure where it even begins! |
| 21:33 | <&[R]> | Sorry, set the DIR= variable at the very start |
| 21:33 | <&[R]> | All it's doing is trying to ls $DIR, then it's parent, then it's parent, then it's parent etc until you reach / |
| 21:33 | < abudhabi> | OK, got it. |
| 21:33 | < abudhabi> | Got a lot of Bs and one G. |
| 21:33 | <&[R]> | B: means it can't list that directory, so that directory needs its permissions adjusted so www-data can read it |
| 21:34 | <&[R]> | G: means it /can/ list that directory |
| 21:34 | <&[R]> | You want to work with the last B: first, then check again |
| 21:35 | <&[R]> | Also you can setup a bind-mount instead of a symlink |
| 21:35 | <&[R]> | You'll want to put it in /etc/fstab so it survives reboots |
| 21:38 | < abudhabi> | Hmm. Would adding www-data to my normal user's group help? |
| 21:38 | <&[R]> | It could |
| 21:38 | <&[R]> | It also means that anyone that can run code as www-data can access the same parts of your home directory |
| 21:40 | < abudhabi> | What other alternatives do I have? chown the relevant subdirectory to www-data? |
| 21:40 | <&[R]> | bind-mount |
| 21:41 | < abudhabi> | OK, how does that work? |
| 21:41 | <&[R]> | Assuming /var/www/ad is a symlink to /home/ad/public_html -> `rm /var/www/ad` (remove the symlink) `mount -o bind /home/ad/public_html /var/www/ad` |
| 21:42 | <&[R]> | Then you need an fstab entry to make it permenant: /var/www/ad /home/ad/public_html none bind 0 0 |
| 21:44 | <&[R]> | Err, I missed a step where you make /var/www/ad as a directory |
| 21:44 | <&[R]> | You need to do that before you try and mount to it |
| 21:45 | | Netsplit Traal.Nightstar.Net <-> Krikkit.Nightstar.Net quits: Degi, @Reiv, @VirusJTG, @PinkFreud |
| 21:48 | < abudhabi> | It's still 403. |
| 21:48 | <&[R]> | Can you `ls /var/www/ad` as www-data? |
| 21:49 | < abudhabi> | Yes. |
| 21:50 | <&[R]> | Okay, can you cat the file you're trying to read? |
| 21:50 | <&[R]> | Again, as www-data |
| 21:51 | < abudhabi> | Yes. |
| 21:51 | <&[R]> | Is the server configuration pointing to /var/www/ad? |
| 21:51 | <&[R]> | Does ps list the lighttpd process as running as the www-data user? |
| 21:53 | < abudhabi> | server.document-root = "/var/www/html" |
| 21:54 | < abudhabi> | I can do run php files that are properly there. |
| 21:55 | < abudhabi> | I have /var/www/html/test.php and /var/www/html/test/test.php - and those two work. /var/www/html/doku/test.php does not. |
| 21:55 | <&[R]> | You can cat that one? |
| 21:55 | < abudhabi> | Ah, I cannot! |
| 21:56 | <&[R]> | There you go :) |
| 21:57 | <&[R]> | Might just be a perm issue on /var/www/html/doku |
| 21:58 | < abudhabi> | OK, gave it +rx and it works now. I suppose I'll have to give outgroup permissions to everything in there. |
| 21:58 | < abudhabi> | Anyway, thank you. |
| 21:59 | <&[R]> | No biggie |
| 21:59 | <&[R]> | I should write a blog and actually document this process |
| 21:59 | <&[R]> | Then I can just link people and explain things fully |
| 22:04 | < abudhabi> | Yes. |
| 22:05 | <&McMartin> | Yes |
| 22:05 | <&McMartin> | tech blogs are the greatest even when they're super sporadic |

| 22:17 | <&[R]> | abudhabi: did you have any lingering questions about the process I showed you? |
| 22:25 | < abudhabi> | No. |
| 22:25 | < abudhabi> | Managed to get things running afterwards. |
