27.0.50; tramp fails to use ssh on LibreCMC (no base64 encoder available, and not mentioned in tramp manual)
Wed, 08 May 2019 13:25:19 -0300
Hello. I believe I have found a bug in either tramp.texi or
How to reproduce:
 set up a vanilla installation of LibreCMC (or OpenWRT, I've
reproduced this on both) on a wireless router. Suppose it's IP
 ssh into the router as root and create a file,
cat > test
 from another machine, fire up emacs,
 try to use tramp to access the file using ssh:
C-x X-f /ssh:firstname.lastname@example.org:/root/test
(or using the IP address, or host name, of the router, whatever it is)
Emacs will respond with an error, complaining about a "wrong method".
This is because line 3174 of rtamp.el was reached. It is the default
case of a COND expression that has other two cases:
- (or (tramp-local-host-p v)
(tramp-method-out-of-band-p v size))
- (rem-enc ...)
The rem-enc function should use a base64 encoding program on the
router (but LibreCMC and OpenWRT do not have it!).
If, on the router, I install base64:
# opkg install coreutils-base64
then tramp succeeds.
So, I believe this should be mentioned in the manual
(in the info node Configuration -> Remote Programs
there is a list of required programs, but neither uuencode nor
base64 are mentioned)
I'm willing to send a patch to the manual - however:
reading lisp/net/tramp-sh.el I get the impression that tramp
actually *should* be able to encode/decode using busybox/awk,
which *is* available in LibreCMC (or did I get it wrong?).
So, I'm not sure if this is a tramp bug (can't use awk to encode/decode
files in base64 format) or bug in its manual (doesn't mention that
a base64 binary is needed on the remote side).

Thanks for the feedback.

Yep. I'm closing the bug.
Best regards, Michael.
