Hello. I have recently installed DD-WRT v3.0-r30631 mega on a Belkin F7D4302 v1 and am now trying to install YAMon.
I have enabled USB access and SSH access which I can logon to no problems and see the files on the USB stick. But it won't let me copy files from the USB to the /opt directory and just says "Read-only file system", how can I enable write access please? I am logged in as root and chmod doesn't do anything either.
Thanks.
PS. Apologies if this post is in the wrong place, this forum is a bit of a monster!

I presume you selected R/W and /opt as the mount point? Samba or FTP? Does the status show its mounted? I recall that you may have to enable CIFS/Samba under Services or Admin. Post a (resized) screenshot of your USB settings. _________________ #NAT/SFE/CTF: limited speed w/ DD#Repeater issues#DD-WRT info: FAQ, Builds, Types, Modes, Changes, Demo#

I'm not sure why it's being scaled down even more but here it is anyway, you can click on it to see it better. However, the issue is that I can't get write access on the router itself, I have no problems accessing the USB stick and the router folders from SSH.

Ok so /mnt works fine; what is the output of `mount`? Try to remount it R/W. Anyone else seen this? I've not used /opt nor yamon. _________________ #NAT/SFE/CTF: limited speed w/ DD#Repeater issues#DD-WRT info: FAQ, Builds, Types, Modes, Changes, Demo#

root@DD-WRT:/# mount
rootfs on / type rootfs (rw)
/dev/root on / type squashfs (ro,relatime)
proc on /proc type proc (rw,relatime)
sysfs on /sys type sysfs (rw,relatime)
debugfs on /sys/kernel/debug type debugfs (rw,relatime)
ramfs on /tmp type ramfs (rw,relatime)
none on /dev type tmpfs (rw,relatime,size=512K)
devpts on /dev/pts type devpts (rw,relatime,mode=600)
devpts on /proc/bus/usb type usbfs (rw,relatime)
/dev/sda on /tmp/mnt/discsda type fuseblk (rw,nosuid,nodev,relatime,user_id=0,group_id=0,allow_other,blksize=4096)
How can I remount the filesystem I'm already in, and have nowhere else to move to? I'll copy in my exact errors too -
root@DD-WRT:/tmp/mnt/discsda# cp install.sh /opt
root@DD-WRT:/tmp/mnt/discsda# ls /opt
lib
root@DD-WRT:/tmp/mnt/discsda# cat install.sh > /opt/install.sh
-sh: can't create /opt/install.sh: Read-only file system
You can save a lot of grief if you simply change the volume name on your usb stick to opt. DD-WRT will auto mount the volume named opt to /opt. _________________ Segment 1 XR700 10Gb LAN, 1Gb WAN ISP BS
