Thanks for your kind words. I'm glad my work gets noticed and is appreciated!

Permissions problem with mod_sftp

Will Cosgrove — 2012-05-25T19:42:02

Hi Guys,
We've run into a curious problem with libssh2 (1.4.1) with users using proFTPD (1.3.4) and mod_sftp.  What is happening is when we open a remote handle for *reading* like so:

remoteHandle = libssh2_sftp_open(session, file, LIBSSH2_FXF_READ, 0);

The server wipes out the file permissions.  I.e., sets them to 000.  According to the docs, if the file exists on disk it should ignore the mode bits.  But it seems not to be the case.

We've tracked it back to the server config setting IgnoreSFTPUploadPerms, if this is set to yes, everything is fine.  This seems like an pretty obvious server-side issue; *however* it works correctly using openssh's sftp client.  

Before I continue tracking this down, do you guys have any ideas what the differences would be between openssh's sftp implementation and libssh2 which would be causing this?

Thanks,
Will

n.p.; thanks!

Also I would like to say a *big thanks* that you always drive forward 
the projects and make constantly releases as release manager so we can 
bring fixes and new features quickly to the users; not only with libssh2 
but also curl and c-ares!
(I dislike that with other projects a year passes by without any release)

Gün.

Care to suggest a patch?


I'm sure that's just a mistake that it slipped in...

Re: ANNOUNCE: libssh2 version 1.4.1

Vincent Torri — 2012-05-25T06:53:50

indeed. I though you were managing yourself this  file (some projects
do that). Normally, config.sub/guess and similar installed files are
correctly copied when you create the configure script (running
buildconf). Btw, I would use autoreconf -f -i in buildconf.

Btw, i'm not sure at all that you should keep config.rpath in the git
repo. Normally, it's one of the installed files

Normally, that procedure does not forcibly update config.sub.

Re: ANNOUNCE: libssh2 version 1.4.1

Vincent Torri — 2012-05-25T06:41:11

strange. How do you create the tarball ? Normally, if you run 'make
distcheck', you verify the build and create the archive. That's a
quite safe way to release a project using the autotools

Argh. Sorry. I've fixed it now locally so next release _should_ be fine.

Re: example ssh2: failed to connect

Daniel Stenberg — 2012-05-24T16:00:31


connect() is called even before libssh2 is used. You probably entered the 
wrong IP address or use the wrong port number?

Jamie Lahowetz — 2012-05-24T15:46:57

I have tried running the example ssh2. When I do I get a failed to connect
error which is triggered by the connect() method. How can I fix this? thank
you.

Paulo Caetano — 2012-05-23T07:24:27

Hallo.

I've noticed an error in the code I've sent, In line 221, where I've
added a check for the socket creation.

Where I had this:
if (socket == -1)
perror("Create socket");

I should have this:
if (sock == -1)
perror("Create socket");

I attached a corrected version.

Thanks.
