Any #Plan9 gurus on the fedi?

I've managed to break my profile causing me to be unable to connect to my account. It disconnects me upon running the profile script. drawterm -c is not an option because it executes the profile disconnecting me before even running the command. drawterm -G's a no-go as well.

Is there a way I can mount my remote home directory into my local (Debian 12) filesystem so that I can fix the profile without running rcpu?

you can pass a command to drawterm -G to run rc -i without the -l so it wont load your profile.

@moody Can I pass this command without the -c flag?

-c is how you pass the command, there is not another way to do it. Why can't you use -c?

@moody
From the man page:

The command to run can be passed with -c cmd ..., otherwise an interactive shell is started. The user's profile is run before the command with $service set to cpu to allow further customization of the environment (see rc(1) for more information).

Problem is that the profile is executed before the command is run, so it boots me before even running the command. This is why I was trying to see if I could remote mount the filesystem to get around this.

Then you can use tlsclient https://git.sr.ht/~moody/tlsclient. I am a bit surprised that drawterm loads the profile before the command.

~moody/tlsclient - tlsclient(1) and rcpu(1) for *nix - sourcehut git

Content warning: scary compiler error

@moody When I try to compile, I get the following. I have the libssl-dev package installed, FWIW.

You need at least openssl1.1 this seems like you only have 1.0 which has not been supported for 3 years and counting.

@m00dy if you can bring up a plan9 instance in qemu (or other vm) you can import your fs (see 9fs).

@moody That's surprising. Stuff in Debian's repositories is often out of date, but not usually that out of date.

Yeah, something does seem a bit fishy, sorry that it doesn't work out for you. I'll get a debian VM going in a bit and figure out whats up. In terms of booting a 9front VM, you should be able to use the live CD for connecting, you don't need to do a full install first. For what that's worth.

@moody Such is the nature of compiling C code. I really wish it had some sort of automatic dependency management, but what can you expect from a language that old?

When the bootcamp is over, I actually want to get into writing software for Plan9, because despite being very C-centric, it seems a nice system to develop for.

Edit: autocorrupt

I figured out the issue, it was somehow related to the ordering of passing the -l flags to cc (ugh!), if you pull the latest code from sr.ht it should build fine on debian stable now. You will need both libssl-dev and pkg-config. I've added debian to the CI builds for this now so this shouldn't slip by again without me noticing. Thanks for the bug report.

Plan 9 C thankfully has none of this insanity, as you've noticed.

@moody So I ran:
./tlsclient -u jlamothe -h 9p.sdf.org -a 9p.sdf.org -p 17019 rm /usr/jlamothe/lib/profile
...but my profile still seems to exist. It's giving me the same error about line 7 when I connect using drawterm.

You need -R to make tlslcient act like rcpu, by default it works closer to tlsclient on 9front. If you choose to just remove the file don't forget to re-run /sys/lib/newuser to generate a new default.
