bootlocal.sh permission denied
« on: August 19, 2019, 06:49:22 PM »
I want to add to bootlocal.sh but when I open in editor and try to save, I get permission denied.

I know NOTHING about linux or tiny core or micro-core.  An employee installed micro-core on a bunch of ancient laptops for me because I didn't want to just chuck 'em.  You know?  But he's no longer with us.

So now, where I work, has a hidden wifi ssid, so I googled and found a bootlocal.sh code ... but I'm not sure if "editor" is even what to use.

I've seen screenshots where apparently you can right-click desktop, go to "TOOLS" and select "ADD to BOOTLOCAL" but I don't get that with these laptops.

I googled and found some codes that were supposed to be for permissions:
sudo chown root:staff /opt/bootlocal.sh
sudo chown tc:staff /opt/bootlocal.sh
sudo chown 775 /opt/bootlocal.sh

but was not sure where or how to use them.  I tried the terminal, but to no effect.

Now, I'm not 100% useless.  I've been using computer for over 35 years, since before windows.  I mean, I had a sinclair computer that I played with as a kid ... so I remember old dos commands, etc.

But still, I'm out of my element here.  Can anybody give a clueless newb some advice?
Thanks!

Hi kirin-rex
Code: [Select]
sudo chown root:staff /opt/bootlocal.sh
sudo chmod 775 /opt/bootlocal.sh
Editor is what I use when editing files.

Right-click desktop, go to  SystemTools->ControlPanel.  Click the  Backup/Restore  button. The  Backup Maintenance  app will open.

Thank you for your answer!

For these codes, how do I use them?  Do I add them to bootlocal.sh with editor?  Do I use terminal?  I tried terminal, but it didn't fix the permissions on bootlocal as far as I can tell.

I also looked at backup/restore, and opened the backup maintenance tool, but didn't see options to add something to bootlocal, but am not terribly worried since you mentioned that editor can make those changes.

Hi kirin-rex
You enter these commands from a terminal:
Code: [Select]
sudo chown root:staff /opt/bootlocal.sh
sudo chmod 775 /opt/bootlocal.sh

You can check it's correct with the  ls  command:
Code: [Select]
tc@box:~$ ls -l /opt/bootlocal.sh
-rwxrwxr-x 1 root staff 132 Feb 28  2012 /opt/bootlocal.sh
tc@box:~$

Thank you very much.  I was able to successfully edit the bootlocal.sh.

However, I'm still having trouble connecting to a hidden wifi.  When I click the wifi icon, of course my workplace wifi doesn't show up.

I looked at this thread:
http://forum.tinycorelinux.net/index.php?topic=19453.0

Thank's nitram.
 Your solution may work, but I was not able to open the SSID for evaluation. But finally I've found this solution.
The way is to use the manual config, wifi.sh can't be used at all. The issue was that wpa need to scan ssid's and test them.
I'm using the channel 11 and it takes roughly 12 seconds.
This is my tutorial:

First need to be created the config file, for example /tmp/wifi.cfg.

Code: (bash) [Select]
network={
scan_ssid=1
ssid="yourwifiname"
psk="yourwifipassword"
}

The most important is the scan_ssid=1 parameter which executes the network scan and enables the connection to the hidden networks. This function is not supported by wifi.sh script. The psk may be used in encrypted format generated via wpa_passphrase.

Than need to be created some script for wpa execution and ip querry. This script may be added to bootlocal.sh for automated execution at boot.

Code: (bash) [Select]
ifconfig wlan0 up
wpa_supplicant -iwlan0 -c/tmp/wifi.cfg -Dwext -B
udhcpc -i wlan0 -t 10

The first line may not be necessary at all cases, but some my dongles need it.
The -t 10 parameter is important to safely obtain the ip, because the wpa need pretty long time to scan all the channels as mentioned above. This gives 10 queries with 3 seconds delay, totally 30 second.

This works well and i'ts simple.
I found though that putting the newly created wifi.cfg in /tmp/ was a bad idea since that gets cleaned out on reboot, so I put it in /home/.

However, I still don't have it working.  However, I really don't know what I'm doing.  I'm just not knowledgeable enough to know if this is the right thing to do.

Hi kirin-rex
The first question is did you install  wpa_supplicant.tcz ?

No, I haven't, but I know I saw a reference to that recently, but unfortunately, today I was working on deadlines and didn't have time to research it, but the little bit I read indicated I have a lot more research to do.

1.  May I assume this is something I need to download?  If so, I'm pretty sure I know how to do that.

Yes. Without that extension (and its dependencies) none of that will work. If you have a wired network connection available for
that machine, you can click on the  Apps  icon to install it.

That's because that answer was just plain wrong and the clown that gave it should have his keyboard taken away. ;D

Thank you for taking time to help me learn this.  I really appreciate it.

I used a wired connection to install wpa_supplicant.tcz ... and in case you're wondering why I don't use a wired connection all the time, it's because I'm going to be running multiple computers and wifi is easier than wiring them all.

Unfortunately, after rebooting, I still don't have wifi.  As a side note:  before my workplace installed our new lan system, with new ssid and password and hidden ssid, I could connect the wifi from the same pc using the wifi icon, and the wifi.db had the information saved.

So here's what I've got so far:
1.  Installed wpa=supplicant.tcz

2.  added the following code to bootlocal.sh and saved
Code: [Select]
if config wlan0 up
wpa_supplicant -iwlan0 -c/home/wifi.cfg -Dwext -B
udhcpc -i wlan0 -t 10
I'm wondering if wlan0 (zero) is correct ... I have only whatever wifi capabilities came with the laptop.  It's not a wifi chip.  Would that be zero, then?

3.  created a document in editor called wifi.cfg and saved it in the /home/ folder, and later to /home/tc/ as well.  In it is the following script
Code: [Select]
network={
scan_ssid=1
ssid="wifiname"
psk="password"
}
and substituted my actual wifiname and password.  I put the wifiname and password in quotations.  Is that what I'm supposed to do, or do I leave them quotation marks off?  I've tried both ways, and neither worked so far.

4.  I used the code you game me earlier
Code: [Select]
sudo chown root:staff /opt/bootlocal.sh
sudo chmod 775 /opt/bootlocal.sh
Which allowed me to finally save the changes to bootlocal.sh

5.  I tried manually modifying wifi.db with the new name and pw.  I'm wondering now if I should delete wifi.db.  Could it be conflicting somewhere?

Because rebooting and trying to run firefox still didn't get me connected ...
6.  I tried running the code I posted earlier:
Code: [Select]
wpa_supplicant iwlan0 -c/home/wifi.cfg -Dwext -Bdirectly into terminal.

This gave me the following message:
Quote
successfully initialized wpa=supplicant
ioct1[SIOCSIWPMKSA] Operation Not Permitted
ioct1[WIOCSIWMODE] Operation not Permitted
ioct1[SIOCSIWAP] Operation Not Permitted

ioct1[SIOCSIWESSID] Operation Not Permitted
could not set interface wlan0 flags (DOWN): Operation Not Permitted

Seems I have a general problem with permissions ...

It's possible you may need to run that as root.

Does that mean add sudo at the beginning?

If so, I tried that.  No errors this time, but no internet.  I'll have to try again when I'm less busy.  I read something about wicd ... I downloaded it, clicked on it, nothing happened.  Probably doing to uninstall it ...

When I have time, I'll come back and see if I can make progress.

Thank you so much for your help.

Hi kirin-rex
Are you sure  wifi.cfg   is in  /home  and not in  /home/tc ?
