I got a bit of a weird problem, I have an OpenVPN Server running on my WNDR3700 router that used DD-WRT.

Server Configuration

push "route 192.168.1.0 255.255.255.0"
server 192.168.1.0 255.255.255.0

dev tun0
proto udp
keepalive 10 120
dh /tmp/openvpn/dh.pem
ca /tmp/openvpn/ca.crt
cert /tmp/openvpn/cert.pem
key /tmp/openvpn/key.pem

As a side note, I've also tried Bridged Mode and it results the same way!

Client Configuration

remote myserver.com 1194
client 
dev tun
proto udp 
resolv-retry infinite 
nobind 
persist-key 
persist-tun 

ca ca.crt
cert client.crt
key client.key
ns-cert-type server

verb 3

I will use comp-lzo and cipher once the tunnel is up.

The problem is that the connection disconnects when I try to remote desktop or surf to a web-site inside the LAN on the VPN-side. But I can SSH and Ping the Server without it disconnecting. But as soon as I try to access a Website ( i.e. 192.168.1.1 the router management interface ) the Ping stops and the connection does not work anymore.

Example

ping 192.168.1.1  -n 1000

Request timed out.

The Time out occurs when I do "heavy" stuff over the VPN. Any suggestions how I fix this? The same setup has worked with another VPN Server Before and I can't see any weird settings.

After following this guide and connecting to the VPN Server, I get the following error:

Sat Mar 06 19:43:08 2010 us=127000 NOTE: failed to obtain options consistency info from peer -- this could occur if the remote peer is running a version of OpenVPN before 1.5-beta8 or if there is a network connectivity problem, and will not necessarily prevent OpenVPN from running (0 bytes received from peer, 0 bytes authenticated data channel traffic) -- you can disable the options consistency check with --disable-occ.

I am using Archlinux and installed openvpn with Pacman.

I want to acheive the following: Connect to the VPN Server, being able to route certain made up hosts through it.

Is this possible?

openvpn --version gives me the following

openvpn --version
OpenVPN 2.1.1 i686-pc-linux-gnu [SSL] [LZO2] [EPOLL] built on Jan 31 2010

Suggestions?

I accidentally overwrote system.dbf in /usr/lib/oracle/xe/oradata/XE/system.dbf

Well I did not actually do it accidentally, however I overwrote it because of other failures in the database.

And when I try running the following:

SQL> shutdown
ORA-01109: database not open


Database dismounted.
ORACLE instance shut down.
SQL> startup
ORACLE instance started.

Total System Global Area  289406976 bytes
Fixed Size                  1258488 bytes
Variable Size              92277768 bytes
Database Buffers          192937984 bytes
Redo Buffers                2932736 bytes
Database mounted.
ORA-01589: must use RESETLOGS or NORESETLOGS option for database open

Now I want to try to Recover the database because starting it in mounted or standard surely doesn't work.

SQL> recover database using backup controlfile;
ORA-00283: recovery session canceled due to errors
ORA-01110: data file 1: '/usr/lib/oracle/xe/oradata/XE/system.dbf'
ORA-01122: database file 1 failed verification check
ORA-01110: data file 1: '/usr/lib/oracle/xe/oradata/XE/system.dbf'
ORA-01206: file is not part of this database - wrong database id

How do I solve this? Is it even possible?

My "real" problem was that I ran the /etc/init.d/oracle-xe configure and it overwrote my old configuration and probably removed passwords and such so my tables were gone, however I found the mytablespace.dbf so I hope that it is possible to recover?

Please shed some light on this.

I have some troubles installing my SSL Certificate into Weblogic 10, here are my configuration steps:

  • Copied the .cert and .key to the server

  • Executed the following:

    []# keytool -import -keystore myKeystore -trustcacerts -alias myKeystore -file myCert.cert -storepass myStorePass -noprompt Certificate was added to keystore

  • Executing the following:

    []# java utils.ImportPrivateKey myKeystore myStorePass myKeystore myStorePass myCert.cert myCert.key Imported private key myCert.key and certificate myCert.cert into keystore myKeystore of type jks under alias myKeystore

  • Running Weblogic

    []# ./startWebLogic.sh -Dweblogic.security.SSL.trustedCAKeyStore -Dweblogic.security.SSL.nojce=true

This gives me the output:

 <Security> <BEA-090171> <Loading the identity certificate and private key stored under the alias myKeystore  from the JKS keystore file /Oracle/Middleware/user_projects/domains/testDomain/myKeystore .>
<Security> <BEA-090169> <Loading trusted certificates from the jks keystore file /root/Oracle/Middleware/jrockit_160_05_R27.6.2-20/jre/lib/security/cacerts.>
<Could not load a jks keystore from the file /Oracle/Middleware/jrockit_160_05_R27.6.2-20/jre/lib/security/cacerts. Exception: java.io.IOException: Keystore was tampered with, or password was incorrect>

Now the Password IS correct, but this doesn't work, why?
