When i try to install unrar for example:
[admin@ASUS_160GB ipkg]$ ipkg install unrar
Package unrar (3.7.8-1) installed in /opt/ is up to date.
sh: rm: Permission denied
Nothing to be done

Please why I always see Permission denied? I am logged as admin and df shows:

Hi,

did this work at any time or is it a permanent error since you installed the router?

Hi wengi,
i finished this tutorial succesfully so it worked before. But now after month of using this happened and Im not aware about anything what I did. Restart doesnt help.

[wengi]

do an e2fsck on /opt.
i guess the file system needs to be checked.

[admin@ASUS_160GB /opt]$ e2fsck /dev/discs/disc0/part2
e2fsck 1.41.2 (02-Oct-2008)
/dev/discs/disc0/part2 is mounted.

WARNING!!! Running e2fsck on a mounted filesystem may cause
SEVERE filesystem damage.

Is it safe to run or better be unmounted? And it is possible to run when /opt is unmounted? (When speaking about unmounting I dont know how to unmount umount /dev/discs/disc0/part2 doesnt working) umount: Couldn't umount /dev/scsi/host0/bus0/target0/lun0/part2: Invalid argument

And which parameters to use with e2fsck ? Is it e2fsck /dev/discs/disc0/part2 ok?

[wengi]

stop all services running on /opt so it is not used any more.
then unmount /opt

Can you help me to find what more is running at /opt?

You should try

umount /opt

if you get a "umount: cannot umount /opt: Device or resource busy" then begin to kill services.

i would guess vsftp and smb.

Hi, I was unsuccesfull again Killed everything what I thing and still cant unmount.
Is it possible to change pre-mount at /usr/local/sbin to not mount disc and restart and check it?

I have pre-mount from you. How i can modify it? Thanks a lot.

[al37919]

the simplest way is just:
flashfs disable && reboot
after that disk will be automounted to something like /tmp/mnt/diskX_Y (check exact name), but none of the services related to disk will be started. Then you
umount /tmp/mnt/diskX_Y
now it should work. Then run e2fsck. When you finished:
flashfs enabled && reboot

flashfs disable && reboot gives me:

[admin@ASUS_160GB root]$ flashfs disable && reboot
/sbin/flashfs: /sbin/flashfs: 20: cat: Permission denied
/sbin/flashfs: /sbin/flashfs: 73: nvram: Permission denied
/sbin/flashfs: /sbin/flashfs: 73: nvram: Permission denied


EDIT: So, i tried this flashfs disable && reboot in few seconds after restart (before router mounted discs) and now i cannot connect with putty to it (gives me connection refused). But I discovered that i can access command line from web interface and finally unomunted it
Then i run e2fsck and it gives me that it needs terminal to interactive. So I tried e2fsck -p and then I flashfs enabled && reboot. But Problem is still the same.

Maybe e2fsck takes a longer time. How long for 1GB? Or how parameters I must use with e2fsck from web interface?
For info I typed to system command: e2fsck -p /dev/discs/disc0/part2
And it gives: /dev/discs/disc0/part2: clean, 8240/125696 files, 30375/251015 blocks (check in 4 mounts)

EDIT2: So I rebooted 4times to force e2fsck to check disc and to be sure run again e2fsck -p /dev/discs/disc0/part2 but after flashfs enabled && reboot again:
ipkg update
sh: wget: Permission denied

It is possible somehow to do e2fsck with putty?

I have an Asus WL500GPV2 and I decided to try Oleg after dd-wrt (eko's NEWD).
My problem is that I installed OLEG 2.0.1.5 firmware (from forums discussions I found that should be a good choice instead Oleg 3.0.2.6).
I started utelnetd from secret page (utelnetd does not start automatically, I found it in /usr/sbin), and I found no dropbear and no flashfs script on either /bin, /sbin, /usr/bin or usr/sbin.
Can someone give me flashfs script and dropbear to install? And some help to install them?
Thank you very much and I hope to help others too, after I will learn this firmware.

[al37919]

But I discovered that i can access command line

ssh will be disabled, as dropbear is started from flashfs

you can either start it from web-command-line by typing:

dropbear 

or access router through telnet (it should be enabled in the web interface, but then it starts automatically)
