Fixed by adding symbolic links to libssl and libcrypto

I was having this issue also with ejabberd 2.1.6 -- fresh install using binary installer on an Amazon Linux micro-instance I set up for testing.
Seems like ejabberd 2.1.6 wants to link to SSL v 0.9.8 and what comes installed on Amazon Linux is 1.0.0.a.

My problem was annoying because ejabberd would start up OK, but it would not allow any connections - and it didn't crash on startup as previous versions appear to have been doing.

When running in interactive mode (ejabberdctl live) I saw an error about being unable to load the driver tls_drv.so, but otherwise started up fine. However, I could not connect from Adium or any client I tried. When I tried to connect, there was an error in the log about parsing the XML for TLS (encryption), so I went back to the original start up error and tried to see if the libssl version was the issue.

To see the dependencies I used ldd:

ldd /opt/ejabberd-2.1.6/lib/ejabberd-2.1.6/priv/linux-x86/lib/tls_drv.so
        linux-gate.so.1 =>  (0x006c7000)
	libssl.so.0.9.8 => not found
	libcrypto.so.0.9.8 => not found
	libc.so.6 => /lib/i686/nosegneg/libc.so.6 (0x00110000)
	/lib/ld-linux.so.2 (0x0062f000)

So we can see that it can't find "libssl.so.0.9.8" or libcrypto.so.0.9.8

On my machine libssl and libcrypto are located in /usr/lib

So what I did was create symbolic links from those missing filenames to the version of the libraries that I do have

sudo ln -s libssl.so.1.0.0a libssl.so.0.9.8
sudo ln -s libcrypto.so libcrypto.so.0.9.8

So now ldd gives

host lib]$ ldd tls_drv.so 
       ./tls_drv.so: /usr/lib/libcrypto.so.0.9.8: no version information available (required by ./tls_drv.so)
       ./tls_drv.so: /usr/lib/libssl.so.0.9.8: no version information available (required by ./tls_drv.so)
	linux-gate.so.1 =>  (0x00dbc000)
	libssl.so.0.9.8 => /usr/lib/libssl.so.0.9.8 (0x00c89000)
	libcrypto.so.0.9.8 => /usr/lib/libcrypto.so.0.9.8 (0x00110000)
	libc.so.6 => /lib/i686/nosegneg/libc.so.6 (0x00409000)
	libgssapi_krb5.so.2 => /lib/libgssapi_krb5.so.2 (0x00399000)
	libkrb5.so.3 => /lib/libkrb5.so.3 (0x0027d000)
	libcom_err.so.2 => /lib/libcom_err.so.2 (0x00b10000)
	libk5crypto.so.3 => /lib/libk5crypto.so.3 (0x00edf000)
	libresolv.so.2 => /lib/libresolv.so.2 (0x0033b000)
	libdl.so.2 => /lib/libdl.so.2 (0x00354000)
	libz.so.1 => /lib/libz.so.1 (0x00359000)
	/lib/ld-linux.so.2 (0x0062f000)
	libkrb5support.so.0 => /lib/libkrb5support.so.0 (0x00f95000)
	libkeyutils.so.1 => /lib/libkeyutils.so.1 (0x00c43000)
	libpthread.so.0 => /lib/i686/nosegneg/libpthread.so.0 (0x005c8000)
	libselinux.so.1 => /lib/libselinux.so.1 (0x0036c000)

Which is all good (mostly, except the version number warning, but it doesn't seem to matter.)

Then, when I restart the server, all is good and I can connect.

Can someone help out with this please. It would be great if the original poster would post his solution in detail.
I'm also having the same error (open_error,-10) and the .so files are where they should be.

Me, too

Hi,

i am having the same problem, too.
It would be nice if anyone, could provide help for this.
Where do i have to place the symlinks?

Thanks in advance.

Same problem

Hi, I'm having the same problem. I do see sha_drv.so in the ejabber lib directory.

How did you make this correction exactly?

I'm running Centos 5.2 with OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008.

Thanks for any tips.

Thanks to Jonas and deryni on the XMPP chat for your help,

the build was pointing to an older version of SSL libraries and so I've bodged this with two symlinks and it is working just fine now.
