edit : tls-auth , server hardening error

Post by bretsie » Fri Jul 20, 2012 7:08 pm

I'm trying to figure out how to exactly change clients certificate life span.
It's stuck at 3650 days and I can't change it.
I have tried to edit the vars file then build-key, it still says 3650 days.

Do I have to run these commands again?

Code: Select all

. /etc/openvpn/easy-rsa/2.0/vars #i know this contains information on the key infrastructure(bit encryption, ca length, key length)
. /etc/openvpn/easy-rsa/2.0/clean-all #im not really sure what this does
. /etc/openvpn/easy-rsa/2.0/build-ca #from what I understand this builds the server/client ca file that is needed to be authed.
Also, what is the best way to manage clients? I do not use the Access Server, is there a log file where all the clients are saved and their certificate durations are at?

One last question. Does the command..

Code: Select all

. /etc/openvpn/easy-rsa/2.0/build-dh
Build the dh1024.pem/dh2048.pem files that are configured in the var file? Or does this command also access the client/server crt's and keys to encrypt them?

Re: Correct Way to Change Client Certificates? And Manage?

hi there,

here we go
I'm trying to figure out how to exactly change clients certificate life span.
It's stuck at 3650 days and I can't change it.
I have tried to edit the vars file then build-key, it still says 3650 days.
if you are allready had created a cert and you want to change its lifespan
i think the answer is no...

if you want to create a new cert with different life span then simply edit
vars file and change the appropriate SET enviromental value then:

source vars file
run build-key script to create the new cert with the selected life span.

openssl creates index.txt containing info about your created certs.
One last question. Does the command..

Code:
. /etc/openvpn/easy-rsa/2.0/build-dh

build-dh builds diffie-helman parameters file dh(keysize).pem file
diffie-helman algorithm is used for key exchange when the symmetric encryption takes place,
No it does not encrypts client/server crt files..

I have ran into another problem, so I will post it here instead of making a new thread.

I am trying to enable "cipher AES-256-CBC" in my 'server.conf' file. I do so and then add the same cipher into my client.conf. But when ever I use some encryption besides the standard Blowfish encryption my clients can connect to the VPN but not browse while on the VPN. No web pages will display.

Also, what commands do I need to un-comment to fully disable logs?

server.conf file and client.conf file's below.

server.conf

Code: Select all



push "redirect-gateway def1"
push "dhcp-option DNS 10.8.0.1"
port 1194
proto udp
dev tun
ca ca.crt
cert server.crt
key server.key  # This file should be kept secret
dh dh1024.pem
server 10.8.0.0 255.255.255.0
ifconfig-pool-persist ipp.txt


keepalive 10 120
cipher AES-256-CBC   # AES
comp-lzo
persist-key
persist-tun
status openvpn-status.log
verb 3
client.conf

Code: Select all


client
dev tun
proto udp
remote XXX.XXX.XXX.XXX 1194 #Removing my server for security reasons.
resolv-retry infinite
nobind
persist-key
persist-tun
ca ca.crt
cert client1.crt
key client1.key
ns-cert-type server
cipher AES-256-CBC
comp-lzo
verb 3
;mute 20

hi there,

(i removed comments from configs)

can you post the logs from server/client when you connect using AES?
can you ping 10.8.0.1 from your clients when using AES?
to disable logging completely use verb 0

Okay I changed the verbosity to 6 on the server.conf for the AES-256-CBC test.

Here is what I got.

When the client pinged 10.8.0.1 all the request were timed out.

openvpn-status.log

Sorry I'm a idiot, here is the correct log.

After switching to a new OpenVPN client version 2.2.

Now I am receiving a TCP error. If possible keep my server ip discrete.

Re: Correct Way to Change Client Certificates? And Manage?

the above message is clear..

something is blocking openvpn server (firewall on server itself/ or on router / Nat on router not enabled)?

please check it and when it connect post client & server logs.

Re: Correct Way to Change Client Certificates? And Manage?

The fix for this was that when I edited my client.conf, it wasn't actually updating in OpenVPN client. It was still reading settings from a old config.

I fixed it by renaming my client.conf and removing the profile, then re-adding it. Weirdly enough it worked, this was also the problem for when I was changing my cipher to AES-256-CBC, it was saving for the default BF-128 cipher. So this little weird thing fixed a lot of problems for me.

But now I am trying to harden my server from attacks or what it be. Reading the documentation it says 'tls-auth' is something highly recommended. So when I went ahead and tried it, I ran into the following problem.

My server has pretty good specs, it shouldn't be too slow for such a thing. From the research I have been trying to do, it seems to have something to do with my TCP configuration, or tls-auth requires it? I checked with my server administration and they say there is no firewalls or anything blocking anything.

hi there,

tls-auth works with both tcp/udp configs..

check your firewalls...

just to add that i have noticed that errors like this (tls negotiation failed etc)
they had also appeared to me in working installations and a simple router restart (here in greece we have adsl)
fix the problem... :?

I don't understand what I would have to do or my VPS host would have to do to fix the "router" problem. When the problem wouldn't be on my end, nor on the VPS settings. I don't know what to exactly try to fix this problem.
