[Dovecot] Dovecot + Cygwin the 2nd
Hi,
i still try to get dovecot to run under cygwin. After a post on the cygwin list i am able tu run dovecot. Under Cygwin you have to run dovecot by inetd. Starting the binary "dovecot.exe" does not work.
Well the server is running but answers with a fatal error.
Account: 'localhost', Server: 'localhost', Protokoll: POP3, Serveranswer: 'Fatal: EOF while reading environment from master', Port: 110, Secure (SSL): No, error on server: 0x800CCC90, Fehlernummer: 0x800CCC90
This error is from Outlook, Thunderbird just says there is an error without any error message.
So maybe you can help me to bring my story to a hapy end ;-)
Cheers Ronny
Sorry i forgot:

Can you get greeting text if you simply telnet to server?
Can you get greeting text if you simply telnet to server?
I get the same error:
$ telnet localhost 143 Trying 127.0.0.1... Connected to zoidberg. Escape character is '^]'. Fatal: EOF while reading environment from master Connection closed by foreign host.
$ telnet localhost 110 Trying 127.0.0.1... Connected to zoidberg. Escape character is '^]'. Fatal: EOF while reading environment from master Connection closed by foreign host.
By the way, after trying to login i have to clean the directory /var/run/dovecot. Otherwise i get this error:
$ telnet localhost 110 Trying 127.0.0.1... Connected to zoidberg. Escape character is '^]'. Fatal: write_full(master_fd) failed: Transport endpoint is not connected Connection closed by foreign host.

Cheers Ronny Can't sure about this but maybe this problem because different types of EOF symbols used in Unix and Windows systems. So it trying to read from master but unable to do so, because receive EOF symbol from beginning.

OK, so the problem is Dovecot master process isn't passing environment variables to child processes it creates. Does this change anything: diff -r d81c10f9b8ec src/master/main.c --- a/src/master/main.c Tue Dec 11 21:00:14 2007 +0200 +++ b/src/master/main.c Thu Dec 20 20:15:55 2007 +0200 @@ -69,7 +69,7 @@ void child_process_init_env(void) int facility; /* remove all environment, we don't need them */ - env_clean(); + //env_clean(); /* we'll log through master process */ env_put("LOG_TO_MASTER=1"); @@ -866,7 +866,7 @@ int main(int argc, char *argv[]) home = getenv("HOME"); /* clean up the environment of everything */ - env_clean(); + //env_clean(); /* put back the TZ */ if (env_tz != NULL)

OK, so the problem is Dovecot master process isn't passing environment variables to child processes it creates. Well,
i added some code to env_put() to log all the environment variables passed to it.
void env_put(const char *env) { ...
printf("env_put()\n"); FILE *file; file = fopen("/tmp/dov.env", "a");
fprintf(file, "%s\n", env);
fclose(file);
}
after running "telnet localhost 143" there are these variables:
$ telnet.exe localhost 143 Trying 127.0.0.1... Connected to zoidberg. Escape character is '^]'. FBUG: PROCESS_UID environment not given env_put() env_put() env_put() env_put() env_put() env_put() env_put() Connection closed by foreign host.
Administrator@zoidberg ~/dovecot-1.0.9 $ cat /tmp/dov.env RESTRICT_USER= RESTRICT_CHROOT= RESTRICT_SETUID= RESTRICT_SETGID= RESTRICT_SETEXTRAGROUPS= RESTRICT_GID_FIRST= RESTRICT_GID_LAST=
So PROCESS_UID is never set using env_put() till the point where it is looked for!

The code path to set it is in src/master/login-process.c:
login_processes_init() -> login_processes_start_missing() timeout -> login_group_start_missings() -> create_login_process() -> fork, login_process_init_env().
Aren't those called?
