Okay, this is actually not a request for help getting my DNS-321 working, rather I want to know how something works... I put together a bunch of users and groups in the WebUI, then I went into the shell and looked at passwd and groups and found that the users there did not match what I just entered. The users were not assigned to the groups I had put them in and the default path pointed to /root/ftp rather than /mnt/HD_a2 which I found odd. Why is this. Are their two separate user databases?

One other thing, what does the store-passwd.sh script do, does it just write passwd and group to flash?

Any insight would be helpful, thanks!

store-passwd.sh is a plain text shell script, you can look at it with the 'cat' command

Code:

/ # cat /ffp/sbin/store-passwd.sh
#!/bin/sh

echo "Copying files to mtd1..."
mount -t minix /dev/mtdblock0 /sys/mtd1
cp -f /etc/passwd /sys/mtd1/.
cp -f /etc/group /sys/mtd1/.
cp -f /etc/shadow /sys/mtd1/.
cp -f /etc/samba/smbpasswd /sys/mtd1/.
#cp -f /etc/ftp_tbl /sys/mtd1/.
#cp -f /etc/ftpgroup /sys/mtd1/.
sync
umount /sys/mtd1

echo "Copying files to mtd2..."
mount -t minix /dev/mtdblock1 /sys/mtd2
cp -f /etc/passwd /sys/mtd2/.
cp -f /etc/group /sys/mtd2/.
cp -f /etc/shadow /sys/mtd2/.
cp -f /etc/samba/smbpasswd /sys/mtd2/.
#cp -f /etc/ftp_tbl /sys/mtd2/.
#cp -f /etc/ftpgroup /sys/mtd2/.
sync
umount /sys/mtd2

echo "Done."

Looks like it copies, passwd, group, shadow, smbpasswd, ftp_tbl and ftpgroup
/sys/mtd1 and /sys/mtd2 are two areas of the flash NVRAM

I believe that the user's name in 'passwd' and 'smbpasswd' have to match, but I think
the samba password and the system logon password can be different . I don't
know about the ftp_tbl and ftpgroup (ftp function is disabled on my DNS-323)

Thank you, what about the user store, are there more files than just passwd that covers that?

Please explain further, I'm really not sure what you mean by 'user store'?
