[solved] starting eggdrop not within its directory

2007-04-09T10:06:39-04:00

Code:

/*  cdandexec.c  change dir and execute  usage: cdandexec dir cmd [arg]  Version 1.0    (c) 2007 Björn Schreiber */#include #include int main(int argc, char *argv[]) {    // check argv  if (argc < 3) {   printf("usage: %s dir cmd [arg]\n", argv[0]);   return EXIT_FAILURE;  }  // chdir  if (chdir(argv[1]) != 0) {    perror("error changing dir");    return EXIT_FAILURE;  }  // execute  if (execv(argv[2], &argv[2]) != 0) {    perror("error executing cmd");    return EXIT_FAILURE;  } else    return EXIT_SUCCESS;}

This is the little tool I use to start eggdrop in a chroot environment. Perhaps somebody find it useful, so I post it here.

I'm not a C/C++ programmer, so comments are welcome .

you could also edit src/eggdrop.h before compile:

Yes, this was allready mentioned by nml375, but I want to avoid changing the source. And it doesn't solve the problems with other scripts using relative paths.

you could also edit src/eggdrop.h before compile:
#define LANGDIR "./language" /* language file directory */

change "./language" to the full path

Both solutions work. I can start chrootuid with a manipulated EGG_LANGDIR environment and I can put a "cd /usr/local/eggdrop" at the beginning of eggdrop.conf.

The first solution could be a problem for other scripts if they use relative paths without a way to set them - I have to test chanstats and moxxquiz. The second one has the problem that the first messages from eggdrop a shorten to "MSG XYZ", but that doesn't bother me mutch.

If I found some time at the weekend I will write the little start tool.

Sure, you could always use the "cd" command to change current directory.

I'm not too familiar with chrootuid. I don't suppose your eggdrop inherits the environment from where chrootuid were run?

I will test both, this evening. And I will post the results here.
Thx so far.

Ie. doing something like this:

Code:

EGG_LANGDIR=/usr/local/eggdrop/language chrootuid /chroot/eggdrop/ eggdrop /usr/local/eggdrop/eggdrop /usr/local/eggdrop/eggdrop.conf

There are a few other tricks that could be tried aswell, depending on how you start your eggie...

I use something like this:

Code:

    chrootuid /chroot/eggdrop/ eggdrop /usr/local/eggdrop/eggdrop /usr/local/eggdrop/eggdrop.conf

(eggdrop was installed in /chroot/eggdrop/usr/local/eggdrop)

If I can use a special TCL cmd in the conf file to modify the environment, perhaps I can change the current directory using another TCL cmd?

Well, you could access the environment variables from within tcl using the special tcl array-variable "env": ie. setting env(EGG_LANGDIR) to a new value. I'm not sure however if eggdrop has'nt already tried to load languagefiles when the main config-file is read.

As I recall, the only way of relocating language-files is either to edit the source (LANGDIR macro in src/eggdrop.h), or use the environment variable EGG_LANGDIR

Thx for your answer. I allready have done a search BEFORE I post my question - but perhaps I missed the right key words.

I don't want to change the directory structure (f.e. creating links direct unter /chroot/dir/) and I can't execute a shell script.

Is it right that there is no chance for me to use EGG_LANGDIR because of the restricted user account without a home directory and without a shell, too?

Seems to me the only solution is to fix the source or write a little tool which change the current directory and starts eggdrop.

In a chroot environment, your chrooted dir is / so your absolute path should be /modules/ and so on. Another possibility would be ~/modules/ (~ is shorthand for /your/home/dir/ )

Edit: I might've misunderstood the question, after thinking about it for a minute, you should be able to resolve the problem with symlinks (ln -s /path/to/languagefiles/ /chrooted/dir/language)

Search the forums as this problem has been discussed previously.

Hi *.*.

I try to run eggdrop in a chroot environment with a restricted user account without a shell, therefore I can't execute a shell script to change the current directory.

I try to change all relative paths to absolute paths, f.e.

modules/

to

/usr/local/eggdrop/modules/

which seems to work, but I can't find any variable for the language directory and eggdrop nag about missing language files.

Is there a chance to change the language files directory? Or perhaps I can change the current directory with a tcl statement at the begining of the conf file?

thx,
hotrs
