First I tried Foremost and Scalpel

root@vm-ubuntu64srv:/logs# dpkg -s sysklogd |grep Version
Version: 1.5-1ubuntu1

Added the -r option to /etc/init.d/sysklogd (SYSLOGD="-r -u syslog"). This didn't work and I found out that there are another file (thanks to Jon for pointing that out!) /etc/default/syslogd that probably overrides the settings from the /etc/init.d/sysklogd. I don't know why, but it worked when I put the -r there as well.

IRRI Internet vey slow for 3 days- Solved !

We don't know the reason or the cause of slowness of our Internet . It may be a virus Conflicter or some thing new. We have 3 ISP ( PLDT Igate, Unet and Internet2 Preginet)
( 10mbps, 2 mbps and 155 mbps). We isolate the problem using the command "PING www.yahoo.com -t" inside and outside the firewall netscreen.
We turn off one by one our Network infrastructure except our main Cisco router 7200. still problem persist. Again our team isolate the problem by connecting a new Gigabit switch , a core router and a laptop. pinging www.yahoo.com still get some RTO but inside the Router its clean and no RTO. We issue the command " SH int summary" and get some anonymous IQD packet loss and other packet loss. So we decided to restart our Core CIsco router 7200 by this command " RELOAD" and we cross our finger and monitor the ping in our Laptop . It take a while to TURN on automatically the core Router. I think 2 times it self turn off and some POS and GIgEth interface to lights ON.
After a while the Router is totally On or idle. We check again the command "Sh int summary" and notice no packet loss its clean all interface is Zero 0 0 0 .
and our ping monitor in laptop are now Ok no RTO .

Now our commodity internet is quite faster now. I recvd an average 226ms in pinging www.yahoo.con in my desktop machine.

Our Network are still under observation ...


OOOppss.. wait .. our Internet2 Route are not properly Routed.. we need to check our BGP configuration.????

Installing Aventail Connect Tunnel Agent into Linux

1. Create a folder in the target client computer where you would place the downloaded Aventail Connect Tunnel Agent for Linux.


2. Go to the folder. Download and untar the attached tar file using the following command.
   
   I found the file required here http://wireless.depaul.edu/downloads/AventailConnect-Linux.tar. We may want to stick this on one of our own sites...
   

tar -xf AventailConnect-Linux.tar



You should see the following files extracted:


AventailConnect-Linux-8.80.146.tar.bz2

install.sh

version


3. Install the agent with the following command:

sudo /bin/bash install.sh



You should see the following message in your screen:



Installing Aventail Connect 8.8.0.146...
Looking for tun driver... tun is present and correct.
Unpacking archive AventailConnect-Linux-8.80.146.tar.bz2...
Setting up permissions...
Using certificates in /etc/ssl/certs
Done installing Aventail Connect.

Use 'startct' to start Aventail Connect
Use 'startctui' to run the Aventail Connect graphical interface (requires java)
Use 'stopct' to stop Aventail Connect

I had to run 'sudo /bin/bash startct' to start the connection. Works like a charm


4. You should now be able to connect to the IRRIAD network using Aventail.

My Outlook 2007 finally connects to Exchange 2003 with RPC over HTTPS proxy on Vista.

There is this application called "Windows Easy Transfer" that comes along
with Vista. Its in "All Programs" | "Accessories" | "System Tools" menu.
Among other things, it claims to be able to transfer email settings too. You
might want to give it a try.


Please try the following steps on the Vista client:

1. Click Start, click Run, type regedit in the Open box, and then click OK.
2. Locate and then click the following subkey:
   HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\RPC
3. On the Edit menu, point to New, and then click DWORD Value.
4. Type DefConnectOpts, and then press ENTER.
5. Right-click DefConnectOpts, and then click Modify.
6. In the Value data box, type 0, and then click OK.
7. Exit Registry Editor.
8. Please restart the client machine, re-configure the Outlook profile, and try again log on via RPC over HTTP

Again, my Vista setups did not have the RPC key on the computer. So, I created the key, created the value and rebooted the computer. Deleted the old outlook profile, created a new one and tested. This time it worked.
