Hello,
I've just created a new instance of postgres. It's running an a Sun
server running Solaris 10. I configured it with ssl using port 5433.
The server starts and runs. I can connect to it from the local host
and list the databases, connect to them etc. I can't connect to the
database instance from a remote host. I get a message as follows:
walterc@cat:~$ psql -h db -U walterc -d walterc -p 5433
psql: could not connect to server: Connection refused
Is the server running on host "db" and accepting
TCP/IP connections on port 5433?
I know the server is running, so according to the message, it must not
be accepting TCP/IP connections on port 5433. I configured pg_port =
5433 and "with openssl" when I initially configured the server. Are
there other things that need to be done to get openssl started on the
database server? How can I diagnose this problem?
Carol

Have you set listen_addresses in postgresql.conf?
You likely want:
listen_addresses = '*'

What does listen_addresses say in postgresql.conf for this instance?

If listen_addresses is set properly, another thing to check is whether
there is a firewall blocking connections to 5433 at the kernel or
network level.

The files server.key, server.crt, root.crt, and root.crl are only examined
during server start; so you must restart the server for changes in them
to take effect.
http://www.postgresql.org/docs/8.3/interactive/ssl-tcp.html
It's been awhile since I played with this, but there's something about an
environment var, PGSSLMODE.
You can use openssl to verify the server/root ca correctness like
this:
openssl verify -CAfile ./root.crt testcert.pem
assuming openssl in the mix.

Thanks to all of you. Many of my problems have been fixed. My
"listening_addresses" was not set correctly. After I fixed that
problem, I started getting an SSL error. I'm now getting this error
as follows:
walterc@fac-staff:~$ psql -U walterc -d walterc -h db -p 5433
psql: SSL SYSCALL error: EOF detected
I've poked around a lot in my system. OpenSSL is telling me that ssl
is not properly configured. I don't know if the error is accurate of
it's describing differences between its configuration and Postgres'.
Since ssl on my database box has never been used, there's a very good
chance it's not configured properly. I've decided the best tact would
be to get a new version of OpenSSL. The most current version on the
Sun Freeware site, is 0.9.8i.
Are there any issues with compatibility that I should know about.
I'm running Solaris 10 and version 8.3.4 of postgres.
Thanks,
Carol

can you verify the server crt against the CA?

I don't have a root.crt file. According to the postgres 8.3.5
documentation, the postgres should run without it. I'm not sure what
root.crt should contain at this point, and how it should be formatted.
"If the root.crt file is not present, client certificates will not
be requested or checked. In this mode, SSL provides encrypted
communication but not authentication."

oh, I think you need to use some more flags. Take a look at
this howto: http://www.madboa.com/geek/openssl/

right, my file root.ca was self generated using openssl (I'm the CA). It is
analogous to the CA chain you might buy from Thawte or some other trusted
authority. It is the file that I used to sign my server crt file, testcrt.pem.
`
Yeah, you don't need it unless you want to auth a login with pg, but we
are not there yet. You need to verify that openssl is not fubar first, right?

root.crt is just my self signed root authority cert. It is just a file
I created/named with openssl for testing. You place whatever file is
the public side of the chain (you got it from the signing authority)
somewhere and tell the command where to look with the -CAfile flag.
The file testcert.pem was signed by that auth and so is paired with
root.crt.

I do understand that. I just wasn't sure that was causing all my
errors. Also, in the second part of my message there are lines
relating to the encryption. I'm not sure what needs to be in my
postgresql.conf file to handle this. I'm using the MD5 method.

sorry, I didn't read that far and I didn't keep the post, so if I put
something stupid here, well, there it is.
The last time I played with this was 8.2.something, so 8.3.x may
not worky the same way:
I used the following in pg_hba.conf:
hostssl all all CIDR-address md5
with my specific notation for the CIDR.
http://www.postgresql.org/docs/8.3/interactive/auth-pg-hba-conf.html
looks like you can use host and it will allow either ssl or not, so
chose hostssl if you want to keep the clear text guys out.

It's just a file and you tell openssl where it is, where you put it
once it is created. You request this file from your CA (certificate
authority) who will provide you with the root.crt, the public side of
the chain. You can generate your own with openssl. Here's a great
demo: http://www.madboa.com/geek/openssl/#cert

Well, back from the flu. =P
How do I tell postgres where to look for ssl. I've got both the new
and the original versions of openssl. I don't want to remove the
original one because it's loaded on the global zone and I don't know
what other dependencies it might have. Do I have to back everything
out and run ./configure again? I don't see a parm in postgresql.conf.
Thanks,
Carol

this parameter was not available in 8.2.x when I tested so what
I say here has little basis.
1. no equal sign?
2. isn't this a list of values to choose from so should it be:
ssl_ciphers='ALL' ???
3. the doc does not say what happens if the the guy is commented
out: http://www.postgresql.org/docs/8.3/interactive/runtime-config-connection.html#GUC-SSL-CIPHERS
I wonder what the default is?
4. the doc: http://www.postgresql.org/docs/8.3/interactive/ssl-tcp.html
says: "a list of ciphers can be specified" which makes it sound
optional, but again, I'm without clue.
> Do you have any ideas for me to try to solve this problem?
Well, I think when I did it with 8.2 it was by trial and error in
a test environment. I just kept changing stuff and kept a
matrix of where I had been. There is a finite number of things
to change. It might be good to make a list of possible
variable/values. I've not done that, but it might be good
for us to try to construct a howto.

Yes, it does need an equal sign. That was a type-o that I just didn't
see. Fixed and re-ran. Still doesn't work.

Yes, This says "All but ADH and low." I changed this line to just be
ssl_ciphers = 'ALL' . Stopped, started, and re-ran and it still
doesn't connect. The messages in the log file say "cipher or hash
unavailable". Since the files of the ciphers are definitely on the
system, this suggests that either postgres doesn't know where to find
them or the permission on them are wrong.

The default is
#ssl_ciphers = 'ALL:!ADH:!LOW:!EXP:!MD5:@STRENGTH' # allowed SSL
ciphers

It needs a cipher or a hash. I don't know what it might use as a
hash. I found the cipher files. Unfortunately, I have two sets
because I have two versions of OpenSSL running. This might be part
of my problem, but I don't want to take a chance on messing up what's
already running. I don't know how to tell postgres which set of
cipher files to use. It's in the OpenSSL path, but not the complete
path.

I don't understand this syntax, is it described somewhere to your
knowledge. The doc say to see the openssl docs, so I went
fishing there. Maybe one of these will work:

maybe that means the ALL I guessed is wrong, but idunno, the documentation
doesn't say what that string means.

it should, seems like that would have been handled in your compile pointing to
the libs.

I don't know what this means, these are not listed in the openssl docs
that is pointed to. Guess we could go read the pg source and figure
out what they do with this config line, maybe. We need a clue here...

I thinking that is covered in the compile and you are not using the config
line to pgs liking, but that's just a guess.
Sorry, I can't try this stuff myself, buried in Oracle cruft right now.
