Hhmmm, PKGBUILD was last updated 2 years ago. Strange .... Anyway lets try it.

pacman -Ql otpw

otpw /usr/
otpw /usr/bin/
otpw /usr/bin/otpw-gen
otpw /usr/lib/
otpw /usr/lib/security/
otpw /usr/lib/security/pam_otpw.so
otpw /usr/share/
otpw /usr/share/licenses/
otpw /usr/share/licenses/otpw/
otpw /usr/share/licenses/otpw/LICENSE

Got this little annoying error

   $ otpw-gen

Generating random seed ...
sh: line 1: netstat: command not found

Not sure if it's caused by this PKGBUILD, of if it's just the software that is too old and apparently not maintained ?, at its homepage, https://www.cl.cam.ac.uk/~mgk25/otpw.html

Latest release: Version 1.5, 2014-08-07

pacman -F netstat

core/net-tools 2.10-1
    usr/bin/netstat
community/munin-node 2.0.69-1
    usr/lib/munin/plugins/netstat

pacman -Fl net-tools

...
net-tools usr/bin/arp
net-tools usr/bin/ifconfig
net-tools usr/bin/ipmaddr
net-tools usr/bin/iptunnel
net-tools usr/bin/mii-tool
net-tools usr/bin/nameif
net-tools usr/bin/netstat

I wanted to try this setup. Apparently the Archwiki page, https://wiki.archlinux.org/title/OTPW seems maintained and updated.

I'm also not going to install net-tools, as it is an old and deprecated set of tools.

Is there any other tool or instructions for this "otpw" setup in Arch ? Anyone has any comments and recentt practical feedback experience on this ?

I'm actually not even interested in the SSH part. Just wanted to test OTP for local logins.

This is on armv7h

Successfully built & used on armv7h, you can add that to the supported architectures
