I too have the issue. I am using RT-AC87U and Asus Merlin Version- 384.9
I am getting the below error:
Feb 21 19:34:29 dnsmasq-dhcp[783]: failed to write /var/lib/misc/dnsmasq.leases: No space left on device (retry in 60s)
Feb 21 19:35:29 dnsmasq-dhcp[783]: failed to write...
I wish there was some way of Asuswrt-Merlin having adblockers installed in their packs. It would have been very useful. Does any one know if it could be done with the existing Asuswrt-Merlin setup.
Can anybody help me in a detail as to how to connect with SSH to install the astrill script. I am a student of ssh scripts and unable to login using SSH
