Hi,
Can someone help me with compiling passh for openwrt? (I never ever compiled something :-) )
And need passh for my micro wrt router (GL-AR750S)
Iam on OpenWrt 18.06.1, r7258-5eb055306f and installed "make" but it can't find "cc command".

Which is the best method for newbies to compile?

Maybe it's pssible that you can create a "compiled release" here??

best regards

sshpass is quite happy with pipes, as mentioned in README.md.

I tried compiling passh on AIX 7.2.0.0 with gcc-8.3.0 on ppc64le

It fails with the following:

Stop.

/usr/include/sys/ioctl.h:357:#define    TIOCSWINSZ      _IOW('t', 103, struct winsize)  /* set window size */

sshpass-1.06 does compile when I add #undefine malloc to config.h.

As mentioned in README.md, sshpass is broken, and I experience it on AIX. sshpass only works intermittently. I'm hoping to give passh a try, but both sexpect and passh does not compile unfortunately, and is not available on AIX Toolbox for Linux Applications. passh does work and compile perfectly on a x86_64 Linux instance.

Thank you

hi,
is it possibile to hide the password prompt just like sshpass does?
this is kind of an issue mostly when redirecting command output...
example:

$ passh -p password user@host pwd > out
$ cat out
user@host's password:
/home/user
$
$ sshpass -p password user@host pwd > out
$ cat out
/home/user

Like grep -E.

Not sure if REG_EXTENDED is always defined on all systems. Can use #ifdef.

Problem definition: Maybe it waits (N+1)'s password prompt, but if no password prompt (or less than (N+1)), then it cause successful ssh program start and infinite waiting block.

How to reproduce: Just try to start, e.g. when there is already public keys, or other variant when no password prompt.

I read the readme , but can't find any mention for the argument of port :)

Hi, I had problems with sshpass in freebsd, so I thought i'd give passh a try.

I need to rsync data from a nas to a freebsd machine. Use of ssh keys is disabled, as a lot of other stuff as well. (Avoid Seagate if you're buying a nas.)

However, I get an error when trying to compile.

$ make
cc -O2 -pipe  passh.c  -o passh
passh.c:805:49: warning: implicit conversion from 'int' to 'char' changes value from 255 to -1 [-Wconstant-conversion]

*** Error code 1

Accidentally discovered it with:

$ passh -p file:~/.ssh/pass.bastion ssh host.domain.tld

But it seems passh doesn't expand ~. So on the full path it worked, but once provided a non-existing path to the file it crashed.

Hi @clarkwang! ☀️
I am attempting to use passh to input the password for an RSA key on Travis-CI.
The passh.c compiles successfully, but when I try to use passh in an ssh command,
it still asks me for the password! 😞
please see: https://travis-ci.org/nelsonic/hello-world-node-http-server/builds/384184242#L458

The password for the SSH key is loaded as an environment variable SSH_ASKPASS
but for some reason it is not being "piped" into the ssh command.

What am I doing wrong?

Any help much appreciated. (thanks!)

I am trying to package passh to NixOS but the fact that there is no license is a bit scary, and makes it hard for this to be merged.

Could you please choose a license?

Thank you!

Hey!

When connecting with ssh and a key, you can start typing stuff while authenticating and this will be provided to the next process listening to stdin. When using passh, what is received on stdin seems to be transmitted to the remote end even when not interactive yet. Would it be possible to avoid this?

Just saying thanks!

I also would like to share that I can use this for more than just inputting the password. For exemple, for unison, I could use this to both enter the password and answer yes to the question Proceed with propagating updates with the unison bidirecional sync tool:

1. passh -P 'Proceed with propagating updates' -p y passh -P '[Pp]assword: \{0,1\}$' -p password unison ...

unison has the builtin option called -batch to answer yest to this question Proceed with propagating updates, but I had to manually answer yes because the -batch option also implies to ignore conflict and fail silently. But I would not like for it to fail silently, but ask for my input. Then, putting passh to answer y to the input question Proceed with propagating updates fixed my problem because when there is a conflict, y is not a valid answer (but f, <, etc).

Hello,

Passh is very usefull, with it I can easly "have a tty in a webshell". 😉

I want to use it to write "passh scripts", so I published a little project to help to write this "passh scripts" :

Thanks for passh 👍

Hi!

Just wanted to let you know that passh is now available as a package on FreeBSD: https://www.freshports.org/security/passh

Currently, we are just using the date of the last commit as a version number. I'll gladly switch to a real version if you decide to create a tag one day.

Cheers!
