kha is just starting out
Default Permission denied on several scripts

Hello,

This morning I logged onto my RT-N66U with latest Merlin firm. (Firmware Version:3.0.0.4.270.24 (Merlin build)) to check crontabs.

I ran:

Code:
cru l
and got:

Code:
[kha@RT-N66U root]$ cru l
/usr/sbin/cru: line 4: nvram: Permission denied
Line 4 is:

Code:
F="$D/`nvram get http_username`"
If i run it it works:

Code:
[kha@RT-N66U root]$ nvram get http_username
kha
It's like the interpreter does not work... Yetserday I installed through ipkg packages bash, bash-completion and core-utils... I am wondering what can cause this issue: when runnign scripts, it's like the interpreter does not have any right to run binaries...

i also tried to run

Code:
ipkg update
but got:

Code:
[kha@RT-N66U root]$ ipkg update
Downloading http://ipkg.nslu2-linux.org/feeds/optware/oleg/cross/stable/Packages.gz
sh: wget: Permission denied

That error message is normal. Asus doesn't have a fully working optware repo, so there's no Packages.gz file.

No idea, you only posted logs of the ipkg update, not of the bash install attempt.

After installing bash, the prompt changed from # to $, indicating a loss of root privilege.

It's a optware-related issue, because a long time ago when I use TomatoUSB I had the same problem, and I solved it by editng some file like /opt/etc/profile, but I don't remember exactly nor how, nether can I google anything out today. Waiting for a solution.

Here is how to reproduce the issue:

1. Make a clean install of optware. Can be done by installing Asus DownloadMaster and then uninstall it.

2. telnet/ssh to router, you will be prompted with a # and no problem.

3. ipkg install bash, then exit the telnet/ssh session.

4. re-telnet/ssh, you'll be prompted with a $, root privilege lost.

5. umount the optware device. re-telnet/ssh, you gain root again, no problem.

6. telnet/ssh after optware device mounted, you lost root.

Appreciate a solution

I got it. Edit /opt/etc/profile
change this line
LD_LIBRARY_PATH=/opt/lib:${LD_LIBRARY_PATH}
to
LD_LIBRARY_PATH=/lib:/opt/lib:${LD_LIBRARY_PATH}

Problem solved. So it's a lib path search order issue.

BTW, the PS1 should end with \$, instead of $, otherwise always shows $.
