deploy_router script not working on Asus Merlin 386.7.2 anymore #8

Closed roshan-riazi closed 2 years ago

roshan-riazi commented 2 years ago

Using both release version and also the latest codes, deploy_router script gets stuck after binary file(s) (v2ray-linux*.zip) have been copied to the router. As far as I can tell, the problem is with "SSH $target bash" commands and "bash <<< ..." syntax. Also (on release version) when I stop that, the next ssh returns "bash: syntax error: unexpected redirection" error (which also seems to be related to "bash <<< ..." syntax).

Tested with: Asus RT-AC86U running Asus merlin 386.7.2, fresh Install with Entware and USB Swap. Predownloaded binary is v2ray-linux-arm64-v8a.zip with v4.45.2 which installs easily on AC86U. Release version code (v4.44.0) and and latest codes from git both have this problem. Note that Release version uses a separete deploy_start.sh but latest codes from git use "https://gitlab.com/zw963/deployment_bash/-/raw/v0.8.3/deploy_start.sh" and this problem is persistent with both of them.

As far as I checked, if I use fresh install (+ Entware and Swap file), "bash --version" on router will not output anything. Also it seems that bash is the default shell ("echo $0" returns "bash") and "which bash" returns "/bin/bash".

Also, as far as I can understand, you don't need to unzip and copy xray binary file on router (you are not using it in your router related codes later).

Another thing that may help is that when I manually install "perl" using Entware (opkg install perl), default shell on router changes to "sh" ("echo $0" returns "sh").

Solved! I installed bash using Entware (opkg install bash) which made "which bash" equal to "/opt/bin/bash". After that, in the deploy_start.sh I replaced two instances of "ssh $target bash ..." with "ssh $target /opt/bin/bash ...". It seems that my router (actually newer merlin firmwares, because I tried it many times from fresh install) had problems with bash reference.
