Hello everyone. This is what I'd like to do: In my iPhone app, I'd like to call the Dropbear client code in order to create an SSH tunnel to another machine. I do not want an independent ssh command-line client.
I will be running the client code from an iPhone thread. I do not want X11 forwarding or SSH compression. Easier said than done. I guess. Quick info about myself: I am a serious developer who knows a few things about iPhone, Objective-C, C programming and UNIX. Been with UNIX since '84. Yes, I'm, old(er). So, I don't need hand holding here, just a few pointers to get me going. Naturally, I will post my results as I tend to do, see my blog at: http://www.xm5design.com/ Ok. So my initial code inspection turned out the following: in "cli-main.c" there is a way to start the code without a "main()" which would clash with the "main()" in any iPhone app. This is good! However, the defines: "DBMULTI_dbclient" and "DROPBEAR_MULTI" are not exactly clear on their meaning. There is a "cli_dropbear_exit" function that seems to be the central exit gate for the client code. If true, this is fantastic since I don't want to Dropbear code to "exit()". I want a nice "return()" which will shutdown the dropbear thread gracefully (or re-start). Problem: I can't really use the Makefile genned by configure since I will execute the code from Xcode. Any hints? I tried a simple test on my OSX machine like this: ./configure --disable-zlib --disable-syslog --disable-lastlog and then: make PROGRAMS="dbclient" >make.log 2>&1 and I got a working client binary. I was able to ssh to another machine, etc, etc.. However when I do: "otool -L dbclient" (otool is like like ldd) I only see "/usr/lib/libSystem.B.dylib" no other lib. Does that mean I don't need the libraries in "libtomcrypt" and "libtommath" for a simple client code? Please accept my thanks ahead of time for this. Any help is appreciated. -George H.
