Hi All, I want port the openssh on an embedded system based on powerPC. Is there any document that can guide me to start?

A necessary first step would be getting OpenSSL working on your platform. -d
You'll need to ensure you have zlib and openssl at least. Depending on the PowerPC OS your using you may need additional helper functions (IE openbsd-compat/). Otherwise there is not much more for documentation to help with porting. Feel free to post issues for the platform in question and we may be able to provide assistants on an issue by issue base. Or work to get the hardware into one or two of the developer's hands in the OpenSSH project for them to work on the port. - Ben On Tue, 16 Nov 2004, mike zheng wrote:> Hi All, > > I want port the openssh on an embedded system based on > powerPC.

Mike,
You may have an easier time getting Dropbear to work.

As mentioned, this becomes much harder if you don't have a POSIX
layer. Some commercial solutions you may want to look into:

Hope this helps!

A couple of years ago, I ported OpenSSH to Nucleus. While Nucleus is not exactly the same as vxWorks, the obstacles you'll need to overcome will probably be very similar. Mainly, you'll need a POSIX layer for vxWorks, which a few people have already mentioned. Maybe someone has already done this for vxWorks. This would be worth looking into. If not, you could port your own (from OpenBSD for example), though I don't how easy this would be for vxWorks. We did it for Nucleus, and it wasn't really all that bad. I'd also recommend cutting out any OpenSSH functionality that you don't absolutely need in your end product. This will reduce the amount of work you'll need to do to port your own POSIX layer, if that's what you decide to do. For example, if you don't need port forwarding, then remove it. Same thing with PAM, Kerberos, etc. You can significanly reduce the amount of work required if you carefully note your requirements and then start removing modules that you know you won't need. -- Dan -----Original Message----- From: openssh-unix-dev-bounces+dmouldin=enterasys.com at mindrot.org [mailto:openssh-unix-dev-bounces+dmouldin=enterasys.com at mindrot.org] On Behalf Of mike zheng Sent: Tuesday, November 16, 2004 5:28 PM To: openssh-unix-dev at mindrot.org Subject: openssh porting Hi All, I want port the openssh on an embedded system based on powerPC.

Hi All, Does anyone did the porting of OpenSSH to VxWorks? Please let me know if you already done it. Then I may quit my job. :-) Thanks, Mike __________________________________ Do you Yahoo!? Meet the all-new My Yahoo! - Try it today! http://my.yahoo.com
