I use Eraser. http://eraser.heidi.ie/

It will run an a user-defined schedule and simply writes random garbage or all 0's to the unused space of the drive. I like this software cause you can set it and forget it.

If it's a startup message at logon, then Gerbil has the correct answer. This is a very typical thing for companies to do, equiviliant to the MOTD for Linux hosts or networking equipment.

I second that. I always use a VirtualBox virtual machine to look at new OS installs instead of loading to physical HW or messing with partitions.

First, if you are 'new' to linux, do you really think your company wants you to learn linux on its production website and database? No, I don't think so.

RAID is important for most physical servers, 3 disk RAID 5 is pretty standard but raid1,6,10 are also viable options depending on what the server will be doing and how the database will be used. Way to many details to go into on a single post.

For client side mail storage, you must use a PST. Especially if your echange server uses a 30 day retention for online messages....

mike_2000, I've seen many of these, it's usually an add on that loads by simulating a CD. End user runs the 'CD' and can create an encrypted vault ont he USB, just like truecrypt.... Anyone interested in encryption on Windows would probably be using truecrypt anyway.

Make both IPs static and assign the default gateway to be from the primary 192.168.x.x subnet.

Sound like you want to inventory your hosts on a network. There are lots of 3rd party tools that can do this via installable agent. You can also write a logon script if these are all windows machines to pull netbios name and some basic machine info and write that out to a file you can use.

You should probably just restore it from your server's backup and call it a day.

That's what you are doing. Defining the subnets to encrypt on each device. If you setup Cisco Ipsec before, then you should be able to identify these items.

Since it's MS hosted, then multicast is out. Do you get this behaviour with any other large downloads? Hows your ISP health? If you are constantly getting large file download issues from just this one site, that should be easy enough to diagnose if you can get a hold of the right person in support at that hosting company.

The collisions have nothing to do with the cables.

The VPNs from each store currently have 1 ACL to define the 'interesting traffic' along with a nonat for the same traffic. This sends the traffic down to the HQ. You will need to add a new ACE to the crypto_map and the NONAT for all the other stores subnets so that traffic gets swept up also.

I would say to use HQ as a hub between stores, otherwise you are managing 12 tunnels per 12 stores = 144 new IPSEC tunnels.

MAke the new nonat encompas 10.148.0.0 255.255.0.0 and the Crypto_map should have the same. Now any traffic destined for a remote store will match the tunnel's ACL and get encrypted over the tunnel.

From the HQ, you need to add nonats and crypto's to match the new entries from each location. (Remember that the cryptos must match exactly for the tunnels to build properly). You also need to add nonat's from each store subnet to each other store subnet. It will be a big list but it is needed.

Start with inside the network. Are you running split dns? Any issues with round-robining to the sharepoint server(s)? Is it a stand alone server or a cluster? Are files stored in the SP DB or are the files linked from a user page?

For streaming, Are you multicasting internally. ARe your internal switches set to handle mutlticasting properly (if it is being used).

configuring router again is risk prone

And why is that? Configure routing once on the router an you are done.... No static routes on PCs, new devices will route correctly.... PC moved to new subnets won't run the risk of not routing traffic correctly....

This is the way I do it:
http://www.pendrivelinux.com/universal-usb-installer-easy-as-1-2-3/

The application has a pulldown for many popular distros including backtrack.

Setup a Router with DD-WRT. Use any of the 3rd party, OpenVPN providers. You can configure DD-wrt to always use a Remote VPN. The only thing your IT would see are outbound packets to the VPN provider and nothing else.

give default gateway as the router of internet and add intranet router as secondary default gateway

You can't do that. You can only have 1 default gateway.

Even if you add a 2nd gateway, the metric will determine which gets the traffic.
Even if both metrics are the same, then the binding order determines which gets the traffic.

You need to add static routes. How you do this is depent upon the OS you are running.

On a hub (not a switch) when 2 pcs send out traffic it is replicated to every port on the hub. When 2 PCs send out traffic at the same time, the hub detects a collision and each PC will re-transmit the packet after a random length of time.

My 2 cents:

You can't have more than 1 gateway. You should opt to use the gateway that will be used for the 'catch-all', this is usually the one that leads to the public internet. On that gateway, you should add in static routes for other internal subnets and the ip's used to access those subnets (the other gateways).

This is much much easier than adding static routes to every PC.

Not alot of info there....

If you can telnet to the modem's COM Port and type ATDT and get a dialtone, then the hardware is istalled correctly. It then becomes a question of settings for the connection.

No question.

I have a small python script to telnet into a device and issue a reboot.

This works fine for me:

#!/usr/bin/python

import getpass
import sys
import telnetlib

HOST = "host ip goes here"
user = "user goes here"
password = "password goes here"

tn = telnetlib.Telnet(HOST)

tn.read_until("login: ")

tn.write(user + "\n")
tn.read_until("Password: ")
tn.write(password + "\n")
tn.read_until("~ $")
tn.write("reboot\n")
tn.write("exit\n")

tn.read_all()

That command would stop the networking functions. AFter a reboot, networking would start up again automatically unless there was a problem with your configs.

May I assume you edited the /etc/networking/interfaces file and made changes before you stopped networking? If so, you should check there 1st.

what does 'ifconfig' show?

I have two CNAME records added to my AD server.

The Textbook lync setup requires the SIP helper records in DNS.

Look here... this article has the example and the links on how to set it up properly.
https://help.nextuc.com/entries/21807198-How-to-verify-your-DNS-Settings

Can the trouble machine ping and resolve the items as indicated?
Can you manually enter the connection information into the trouble machine's client and have it connect?
Can the trouble machine telnet to the lync server on port 5061 without issue?
Does the trouble machine work from any other location ?

Contacting server and signing in

Are both laptops using the same DNS? Usually, Link servers are identified by the DNS Helper records for SIP. Lync Servers are 'found' on the network with these special DNS records. Usually, sip.mycompany.com will resolve to a lync server to service your client.

Do you have a firewall running on the 2nd machine by any chance that could be blocking ports?

Firefox would use whatever DNS is set on the system.

To test DNS, use this from command line:

NSLOOKUP
www.yahoo.com

Do you get an IP in response. If you do then it's ok. IF you get a timeout or error, then you need to check the DNS entries on your machine or on the DHCP server (the router most likely).

Check each browser and see of you have a proxy set that shouldn't be there, or if you need a proxy address that is missing. This you need to determine since I don't know your network.

From a command line, can you telnet to a web server...

TELNET WWW.YAHOO.COM 80

If you get a timeout, there's a problem with outbound port 80, if you don't, then there is no network issue and it's some browser or other local software/malware issue.

Can we see the config on the NFS source server? Did you allow the correct IP/IP Range to connect?

This is either a homework question, or you are in way over your head if you are asking questions like that.

Can you post the .conf files for each side of the IPSEC tunnel. I don't need to see the .secrets file.

Try restarting ipsec and tail the auth log as it starts with
/etc/init.d/ipsec restart && tail -f /var/log/auth.log

This should show you a seccesful connection or provide some clue as to what's happening.

Agree with JorgeM. The MS DHCP service is pretty solid. I've never had any issues with it once configured.

Start from the public internet and work your way into your network. IF this is just a hardware layout, then show the routers, firewalls, LBs, switches, etc... and the interconnects between each.

Look at some examples on google images for ideas

Not really. More likely that the software can identify the phone you are rooting and has the proper process for that phone in it's code.

Even Samsung has different procedures for its phones. GS2, GS3, and GS4 all have different rooting procedures.

Don't use password auth, use keys instead.

This article explains it all.

http://www.thegeekstuff.com/2011/07/rsync-over-ssh-without-password/

Each device is different. There is no 1 solution that works for all phones makes/models.

If you are really curious, dive into the XDA forums... http://forum.xda-developers.com/

Sweet !!

drindran, you realize that this is a 4 year old thread right?

Does the laptop with the issue work on any other Wifi AP? It could be hardware you know.

Along with that, do you know what filesystem is on the disk? Was it created with Windows, on a MAC, Linux?

Here you go
http://bit.ly/12xKXyq

What version are you running and what does your config file have in it?

Do you mean, how to you run virtualization on a machine that is, itself, virtual? If that's your question, then the answer is that you just run it.

For fun, I one time ran a VMWare Esxi server. Created a Virtual Xen host inside VMWare. Then I created a Windows Server running Hypervisor inside Xen. Then I ran Win7 inside the hypervisor. Then I ran a ubuntu server running in Virtual box on the win 7 machine.... I had too much time on my hands that day.

To recover Passwords in Yahoo you need:
1) The secret question answer
2) You must have setup a secondary, backup email address. You can send a password reset request there.

Without those items, you are out of luck and the email is a loss.

Are you using RHEL as the HOST os (the one running on physical hardware) or as the Guest os (the one running virtual)?

What software are you using for virtualization?

What do you want to know exactly, your question is not understood.

Curious. You could also look at XP local HOSTS file and see if there is anything 'funny' in there. You could also try manually adding a name with IP and see if you can ping that added name from command line.

What web server are you using and on what system? Apache? NGINX?

First, make sure you have view extensions enable as IIM said above.

Does any MP3 open in media player with a double click? IF not, then your file association has changed. Easiest way to fix is to use Windows File explorer (not internet explorer), right click on the mp3, choose 'open with', select 'Choose default program'. Now find and pick the media player for your MP3 files.

Well done Jorge.

Is this homework?

Also, if you are using ubuntu 12 or better, dns entries are made in \etc\network\interfaces now.
i.e.
'dns-nameservers 4.2.2.1 4.2.2.2'
