Issues Getting Filesystem into Read/Write

[g9s0x]

Now that I found where the Asterisk configuration files are located (/usr/local/etc/asterisk/ thanks to the kind help of a few board members) I'm having issues trying to modify the configuration files.  I went to /usr/local/etc/asterisk/sip.conf and tried to configure my SIP profiles but the file was read-only.  I tried to issue a #chmod 777 sip.conf but that would not take.  I got the response chmod: sip.conf: Read-only file system.  I then tried to issue a #chmod 777 /usr/local/etc/asterisk/ which took but did not allow me to make changes to sip.conf still.  I noticed that the configuration files here were pointing to the configuration files located in /tmp/tcloop/asterisk-1.8-samples/usr/local/etc/asterisk/ so I went to that directory and tried to change permissions as well but no luck in being able to modify sip.conf still (in both directories: /usr/local/etc/asterisk and /tmp/tcloop/asterisk-1.8-samples/usr/local/etc/asterisk/).

I then checked the filesystems with #cat /proc/mounts and noticed that there are 19 /dev/loopX filesystems starting with /dev/loop0 and ending with /dev/loop18.  All of these are read-only as indicated by ro.  The two related to Asterisk were /dev/loop15 and /dev/loop 16 and printed as follows:

#/dev/loop15 /tmp/tcloop/asterisk-1.8 squashfs ro, relatime 0 0
#/dev/loop16 /tmp/tcloop/asterisk-1.8-samples squashfs ro, relatime 0 0

So I tried to remount these as read/write using the following commands:

#mount -o remount,w /dev/loop15
#mount -o remount,w /dev/loop16

This did not change them from read-only to read/write.  I reissued the commands with verbose options and got the following output:

mount: mount('dev/loop15' , '/tmp/tcloop/asterisk-1.8' , 'squashfs' ,0x00208021, 'w'):0
mount: mount('dev/loop16' , '/tmp/tcloop/asterisk-1.8-samples' , 'squashfs' ,0x00208021, 'w'):0


I'm not very well versed in Linux so I'm stumped at this point, but perhaps it has something to do with the loop devices?  Any help to get these into a writable state will be MUCH appreciated.  Thanks for taking the time to help out a TCL newbie

That is why I told you to tce-load the samples extension with the -c option.
Remove it from onboot and tce-load -ic the samples extension.
Then you can edit them and back them up after editing /opt/.filetool.lst as instructed previously.

These files are loop mounted and in fact read only.  Please note these are samples and not intended for production use. Create your own config files and put them into /usr/local/etc/asterisk. To keep them after boot, add usr/local/etc/asterisk to /opt/.filetool.lst and make a backup before shutting down system. Doing so your config files will be persistent. And do not install samples to avoid conflicts.

Thanks bmarkus for your kind respectful reply...
