Can't manage to install on M1 Mac

[fratrik]

I followed the brew instructions and got the following

sga-guard <hostname>

doesn't produce any output

Not sure what this one is, but they produce segmentation faults

> sga-guard-bin <hostname>
[1]    62556 segmentation fault  sga-guard-bin <hostname>
> sga-ssh <hostname>
[1]    62609 segmentation fault  sga-ssh <hostname>

I tried downloading go so I could install from source, but could not figure that out.

> go get github.com/StanfordSNR/guardian-agent/...
go: go.mod file not found in current directory or any parent directory.
    'go get' is no longer supported outside a module.
    To build and install a command, use 'go install' with a version,
    like 'go install example.com/cmd@latest'
    For more information, see https://golang.org/doc/go-get-install-deprecation
    or run 'go help get' or 'go help install'.

I am also having this problem

This is on Linux (Arch) as well. I am not familiar with go, updated build instructions are needed.

I got a little further by banging rocks (and doing this: go mod init sga ; go mod tidy ; go mod vendor ; go build)

So, a standard library was forked for some reason. I'm not really sure why, and there's no tests. It would be challenging to update this to modern go that supports arm. I'm more interested in the underlying library to talk to mosh. It would be interesting to break that out into its own library for importing. As a gui though, it would be better suited to a gui friendly language.

Doesn't work using homebrew either for intel Macs. Looking closer it looks like the team just hasn't kept up with the OS releases in general. Is this a dead project? Looking at check ins, it looks like no movement for 3+ years.

[lunasophia]

Sadly, yes, this does appear to be a dead project. The Stanford students working on it have graduated, and the professor leading the project seems to have moved on to other projects as well. Quite a shame, as a mosh developer in mobile-shell/mosh#120 emphatically pointed people here as the One True Solution.

[keithw]

The professor and the Mosh developer are the same person. :-) I think if somebody is willing to take this over, we're interested to hand this over and work with you. I spoke with the original developers (and somebody interested in taking this over) back on Oct. 5 and we were going to work on a transition plan, but I fear intervening events in the Middle East may have taken priority for them. :-(

I don't use mac, but I use the Nix sga-guardian package for different architectures on Linux and there's one for aarch64-darwin.

If you don't use nix as a package manager, you could try extracting the binaries.

https://github.com/StanfordSNR/guardian-agent/issues/33#issuecomment-1122643170 works for me™

Sadly it doesn't work with Go 1.22 since they removed GO111MODULE=off support for go get but everything I tried below it works.
