Hello,
It seems to me that there is some bug in Digital Unix 3.2c when using some
system calls.
I'm currently using WU FTPD and I was surprised not to see some messages in the
daemon.log file.
In fact all the messages are in it just before the following sequence :
if (anonymous || guest) {
/* We MUST do a chdir() after the chroot. Otherwise the old current
* directory will be accessible as "." outside the new root! */
if (anonymous) {
/* the following line is added by me */
syslog(LOG_INFO,"PW->PW_DIR %s", pw->pw_dir);
if (chroot(pw->pw_dir) < 0 || chdir("/") < 0) {
reply(550, "Can't set guest privileges.");
goto bad;
}
/* the following two lines are added by me */
reply(220, "after chroot and chdir.");
syslog(LOG_INFO,"AFTER CHDIR ANONYMOUS %d GUEST %d", anonymous, guest);
So what happens ?
The first syslog works correctly and the PW->PW_DIR message is sent in the
daemon.log file. But, if the "after chroot and chdir." is correctly sent to the
user, the "AFTER CHDIR ANONYMOUS" is absolutely not sent to the daemon.log file.
When the chdir,chroot is not executed, for an identified user, there is
absolutely no problem.
So for me the syslog doesn't work any more after the chroot,chdir.
Bug (or feature) ?
