14492Re: Unslung 6.8 default web admin password
- Aug 6, 2006Hi Mike (and everyone),
I'm having exactly the same problem, so this may be a generic danger
when doing an in-place 5.5 to 6.8 upgrade. I followed the procedures
from the wiki and the readme.
If I could, I would copy the contents of the public/ directory off to
another drive and start over, but I can't access that share. It
doesn't appear to be an authentication error. I get some kind of
resource can't be found error.
I tried reseting the user password for admin, but got an invalid
username/password error (just as Bamber reported). I was using
admin/uNSLUng, after doing an unsling setting the password explicitly
I did numerous iterations of copying passwd files with known passwords
over ones with apparently unknown passwords, and the same with
.htpasswd files, but nothing works.
At one point I got a weird listing from "ls -l":
---x-wx--T 1 root root 20 Aug 6 08:50
I don't know what the "T" means or why the file doesn't have the usual
644 permission flags. I erased the file and replaced it with a valid
.htpasswd file -- still no luck.
Mike, you state:
- your hard disk's "conf" partition should be mounted on
- nothing should be mounted on /share/hdd/conf, and
- the directory /share/hdd/conf should contain a set of symbolic links
pointing to files on /share/flash/conf, and
- each of those symbolic links should be valid (i.e. point to a file
that exists), and
- /etc/passwd should be a symbolic link to /share/hdd/passwd.
I don't see that. I see:
/dev/mtdblock4 on / type jffs2 (rw)
/proc on /proc type proc (rw)
usbdevfs on /proc/bus/usb type usbdevfs (rw)
/dev/mtdblock4 on /dev.state type jffs2 (rw)
ramfs on /dev type ramfs (rw)
/dev/mtdblock4 on /var.state type jffs2 (rw)
ramfs on /var type ramfs (rw)
none on /tmp type ramfs (rw)
/dev/sda1 on /share/flash/data type ext3 (rw)
/dev/sda2 on /share/flash/conf type ext3 (rw,sync)
# ls -al /share/hdd/conf
drwxrwxr-x 1 root root 0 Dec 31 1969 .
drwxrwxr-x 1 admin everyone 0 Dec 31 1969 ..
Maybe this is the source of the problem. I also notice that the weird
"T" flag .htpasswd file has appeared again.
# find / -name .htpasswd
find: /proc/9/fd: No such file or directory
# ls -al /home/httpd/html/Management
drwxrwxr-x 1 root root 0 Dec 31 1969 .
drwxrwxr-x 1 root root 0 Dec 31 1969 ..
---x-wx--T 1 root root 20 Aug 6 10:14 .htpasswd
-rw-r--r-- 1 root root 1370 Dec 31 1969 Button_20P.JPG
At this point, I just want to get my public/ share files out again, so
I can wipe the slate clean and start over. Any thoughts?

that putting it together at this point in time is just too difficult
-- think of Unslung as somewhat "windows-esque": unlike a completely
open Linux system that theoretically could be pieced back together
because all the components are known, Unslung has a large component
that is proprietary to Linksys -- and we have no way of knowing (short
of reverse engineering based on observed behaviour) what sorts of
stuff it needs where on which partition.

only it would be "linksysfsck") and repair it...)
