Right, as they said, make sure the router is completely factory reset. Use the 30-30-30 rule. With power on, hold in reset for 30 seconds, dont let go, now pull power still holding in the reset for another 30, now power it up, still holding reset for another 30.

Now set your laptop to dhcp and plug in via cable to the router. Logon to its gui using default id/pw and start your config.

As a 20 year Network admin, you should know all about running cable. That being said, I always outsource layer 1 stuff to a 3rd party. They will usually do it faster, and it will cost less than your valuable time.

Network admin's main job is to keep the network up and usable for the end users. And if that means having to run the odd cable once in a while, you do it.

Lots of external and internal variables affect wireless speeds.

First one that comes to mind are differences in wifi adapters. Are all machines using same model hardware? Are all using same driver version with exactly the same configs?

External factors include distance from AP, objects in between ap and laptop (walls, furniture, etc), external 'noise' sources (microwaves, other APs).

Which Car gives you the best visibility?

That type of question has only 1 answer.... "It depends."

Many things come into play when determining wifi range. Antenna config, wifi band, power, structural interference, external wifi 'noise', channel contention.

Wifi N offers more bandwidth but lower range and doesn't not handle structural intererence well at all. G has better range, but you are limited to max 54 Mbps. Most consumer based routers offer G and N with varying levels of config and each will give you different results based on environment.

Enterprise grade Wifi solutions are a totally different animal.

HAve you spoken with their support? CHeck with them to see if this has been tested and is supported.

Couple of ideas off the top of my head.

Usually RPC (remote procedure call) could be used to remote execute code on another host. Obviously that won't work here.

Maybe using something like the PSExec http://technet.microsoft.com/en-us/sysinternals/bb897553 in a WINE instance on the linux host might work. But I've never tried it.

Why not run IIS on the windows host and use the same code on that win server instead to call the file? Use a forward on the Linux host over to the win host for that 'link'.

On the linux host, when the link is clicked, have it write out a temp file on the windows host. The windows host could run a scheduled task every minute to check for the existance of a temp file and run jobs based on it's existance/contents.

OK - I'll throw in my 2 cents, though it's been a while since I did any render farm builds.

In older versions of 3d studio, there were specific patches you could apply for specific processesors to take advantage of the increased power of those procs. Without the specific patches, the renders would run in some kind of slower 'compatibility' mode. Now this is going back 7-10 years. So I'm not sure if those issues still exist with the latest versions.

HAve you contacted tech support for your software product and inquired about additional packages to run to take advantage of your hardware?

Usually, you open the IIS MMC. Click on the server, in the IIS section click on MIME TYPES, Click on the ADD... button located to the right in the ACTION pane.

What extension are you trying to add that isn't already present?

If you have physical access to the windows host, then you need a tool like the one included in the hiren cd for a windows admin password change. It's pretty painless. Boot the CD, run the tool, select your windows install location, select the id you want to reset.

Without physical access, you can't do anything.

If your users have admin rights to install items to their workstations, there's nothing you can do to stop one with some skill from bypassing your websense.

The key here is to remove admin rights from the WS so that they canouldn't install tor, or any other vpn/proxy/tunneling solution in the 1st place.

Hold down the ALT key while booting. Keep it down until you get a choice of icons on the screen. You would see 2 drives, 1 for mac, 1 for windows, and a CD rom if you have one loaded.

Usually, the com ports show up as /dev/ttyS0 ir /dev/ttyS1. ttySN where N is 0 through 3 for the normal COM1-4 you are used to seeing.

For a dongle, you need to find the USB port which would probably be set to /dev/tty/USB0 or something similiar. Then you can speak 'Serial' right to that device.

Try using "DMESG | grep usb" after plugging in the usb.

My first guess would be permissions on the files.

Well, it should be fairly easy to script a "WGET <URL #1>" in any linux host and have the run at a specific time. Include 1 file with multiple WGETs and each one should run after the other....

Is that what you had in mind?

Need to get a better understanding of what isn't working? Can you access the router? Does it boot? Does it get an external IP from the network DHCP?

My guess is this: Since linksys default to an internal LAN of 192.168.1.0/24, you probably have the same internal and external LAN. Maybe the linksys doesn't like it.

Disconnect from the network. Connect your PC to the inside lan of the linksys. Your PC should get an IP from the linksys on 192.168.1.0. Conenct to the linksys at http://192.168.1.1 Change the internal LAN subnet to something else... like 192.168.15.0 just so it's different than the office lan. Save and restart. Connect it all back up. Connect to the router on 192.168.15.1 (or whatever you chose) and verify it still has 192.168.1.23 statically assigned on the outside. You should be able to connect though it now.

No ip address via DHCP, no DNs servers created, no gateway set, ....

There's lots of things to check. Start with the basics.

Do you have an IP?
Can you ping your gateway via IP?
Can you ping beyond your gateway to 4.2.2.2?
Can you ping a server by FQDN? Do you get resolution?

Google latitide will report on other's locations. Use it to keep tabs on your kids for example.

2 off the top of my head

Yep - I see no question there.

Looks like it may be a faulty HD. The installer is seeing something it doesn't like. Do you have another to test with?

Somthing like 15 years ago, The old Compaq's (pre-hp) would utilize a section of the hard drive for their BIOS. You would need to use their disks to properly format the installed HD with the startup software that enables the PC to boot. Replace the HD, you need to use the disk to 'prepare' the hd to load the PC properly. That was always Stupid as crap IMHO, but there it is.

IF you don't have the original disks to prepare the HD, then if you need to replace the HD you are out of luck.

In this case, if you removed or messed with the Compaq partition, then the machine may be fubar'd. IIRC, you would get something like a CD/Floppy icon displayed on screen indicating that the system could not find the startup resources.... or something like that.

Antivirus programs are usually 'Active'. This means that the program starts with the OS, is always running in the background, constantly checking files, webpages, downloads, etc.... it is always running. If you have 2 of these running at the same time, they start to step on each other every time they both want to check the file you just opened.

Antialware (i.e. malware bytes) is usually passive. You load up the antimalware run your scan, then you are out. Some, like spybot, can manipulate certain files (i.e. hosts file) to help protect you, but again you are in, run it, then you are out. Some malware apps do have a feature to always run in the background, but it's not a requirement like AV.

Firewalls enable/disable certain traffic. You only need 1 firewall. If you have 2 you double the complexity, but get no additional return.

Is it a single jack for the headset or 1 jack for mic and i jack for speakers? If it's a single jack, then I agree with Stuugie, sounds like a defective headset. If it's dual jacks, just switch plugs.

IF your Machine starts in Safe mode, then we can assume the Hard drive and all the data is ok for now.

Since you know how to start the machine in safe mode using F8, try using the "Last Known Good Configuration" selection from that same menu.

If that gets you no where, then from within Safe Mode use the msconfig utility. START - RUN - 'msconfig' - Enter. MSconfig is a util that lets you turn on/off various startup items.

MSCONFIG will have 5 tabs at the top. Click Services and select Disable ALL, then click Startup and select Disable ALL, then reboot.

If this works, go back into msconfig, and reenable all the startup items, reboot again. Did this work? If yes, then you know it was nothing in this list. Disable all again, go back to the Services Tab and re-enable all services then reboot. If the laptop fails to boot, you know it was something in that list.

BTW, anytime the laptop fails to boot, just go back into safe mode to re-run msconfig.

Once you identify which tab contains the item causing your failure, then begins the long process of trail and error as you turn on some services, reboot, and see if it fails. Turn on a few more, reboot, see if it fails, and so on. once you identify the culprit, you can disable the item, uninstall the app to which it belongs, or take appropriate action.

Good luck.

We need much more info. What does the screen show while booting? Where does it stop? Can you post some screenshots?

Contact Dell tech support. Even if your PC is out of warranty, they will still talk to you and try to help. You just won't get any free, replacement parts.

In MacOS or Linux use
wc -l <filename>

In windows, I don't know of a command line tool. I just use notepad++ to check the file.

A google search will give you various scripts to do the same from cli.

Some things to check:

Are you on wireless? Do you know if you are on wireless G or N? PC/Macs will give you the speeds of the wifi connection in the status info.

Wifi speeds are in Megabits per second, bit Megabytes. So a 24 megabit per second conenction is a 3 megabyte connection per second.

Are you worried about internet speeds? 1st check your ISP service. What speed should you be getting from them. Next, use an online speed tool like http://www.speedtest.net/ to verify you are actually getting your speeds.

Are you running any apps that access the internet constantly. uTorrent? Did akamai sneak their stupid peer to peer tool on your system? These all take bandwidth.

Any luck with those pics? Hard to tell whats going on from just the description.

Couple of items here for clarification.

Email services can be run on a server. That's established. The Server that services certain domains (i.e. someone@company.com) 'could' be in your network, it 'could' be hosted by a 3rd party company, it 'could' be a cloud style email (i.e. gmail, yahoo mail, etc...).

A server can support more than 1 domain. 1 host can handle mail for company1.com and company2.com at the same time.

All emails will be stored on the server that services a particular domain. These stored emails will be there until you view and/or retrieve them using a mail app or a web page.

A client can be setup to pull mail from a mail server and then delete the mail form the server (because you now have it on your machine). However, it can also be set to leave aa copy on the server.

Web based emails are almost always left on the server until you delete them. Gmail and yahoo are examples.

Even if you delete mail from the servers, any good admin will have backups of the hosts and potentially, backups of your emails.

Sleep mode is a very low power mode where the laptop will maintain memory and sessions using as little power as possible. Network connections are usually lost in sleep mode but can be maintained with proper settings.

If power is lost, your laptop's battery will maintain the sleep state until it runs out of juice.

Hibernation mode is where a pc will write a special file to the HD that contains all the info from memory and running sessions. The PC can power down. When the PC starts again, it will check for the hibernation file and if it exists, will load the contents and should get you back to the same state. Network connections can not be maintatined in this mode (for obvious reasons).

Have you tried
net user <user> "this is the password"

I don't know if that will work but worth a shot. ALthough you may end up with a password being "this

Keep hitting F8 as the computer stars up. You should get to the start menu with safe mode as an option.

You might have dns hard coded to some value so that the dhcp'd info doesnt get applied.

Maybe you have some proxy setting applied that could be interfering.

It's not RHEL, but my page has instructions for DNS here: http://www.slsmk.com/?p=21

TeamViewer and VNC get my votes. Teamviewer is my new fav because of the native support for VPN and connections through NAT. VNC requires that you get yourself connected to the remote machine via route or VPN.

If it is a perimeter block, then use a SHH tunnel through your home.

This depends on alot.

Most DB apps will come with some sort of management. I.e. MS Sql comes with its SQL mgmt studio.

What DB are you using?
What OS is the host using?
What are you trying to 'manage'? Backups?

Do you have an existing lan? Are you trying to get 2 machines to speak to each other? Trying to get a shared internet connection? Mayber trying to share a printer?

We'll need more info.
- what equipment do you have ?
- what are you trying to accomplish (see my questions above)?
- Is there anything already installed?

Don't forget Cisco also has their proprietary VOIP solutions with CUCM, Messaging, and management.

You don't need to PAY for Antivirus. Plenty of free options out there. Avast, AVG, etc... I would not recommend anyone run a windows pc without it. The time it takes to clean up an infection costs lots more than the slight inconvience of the AV running.

Use AV in combination with a Hosts FIle blocker i.e. Spybot. And use PeerBlock to be extra careful. Scedule a maware bytes scan once a month and you should stay clean.

Building anything with 1 esxi host will not save you downtime as the patching for esxi requires frequent reboots. Be prepared to have downtime anyway.

Usually, perimeter firewalls are an appliance. You can of course build a dedicated host for this, but usually the appliances are just as good and can be cheaper depending on your needs.

Any tower server with multiple 5 1/4 inch slots can probably use a forward facing hot swap drive tray. Essentially, any SATA is hot swap. I've seen a nice piece of hardware that sets the drives forward facing in a cage granting access to 4 drives at once without shutting down the host.

Don't do RAID in an external enclosure for your Guest OS drives. It would be good for general storage, but too slow for multiple machines running on it.

External SAN with jumbo frames enabled is a good option for ESXi and I use it with great success running 80 servers off an equallogic array across dedicted gig links with 9k jumbo frames enabled.

Yes, what you get looks like a 'series' circuit where internet is delivered by modem, modem goes to router 1, router 1 goes to router 2.

In this case, I don't see the need for multiple routers. All you need is a router that suports a dmz connection of does port forwarding in order to support at home web servers. DD-wrt does this well, but most consumers routers do this anyway.

I would not use a home network for any serious web work. You can easily get a hosted service for $10 a month. IF you know what you are doing, even VPS service can be had for $5 a month.

Microsoft has a tool just for this. "Windows 7 USB/DVD download tool". IT lets you create a bootable USB from an ISO file. I've used it many times.

That makes no sense. Whoever said that is 100% wrong.

A Switch is a layer 2 device. A router is a layer 3 device. Getting a router connection means that all lower layers are working properly.

MACs and PCs can speak the same SMB or Bonjour protocols if that's what you mean....

VPNs are ALWAYS slower than your normal connection. Instead of sending traffic directly to a web server, your traffic must be encrypted/encapsulated (this causes packet data overhead), sent to the VPN server, the server must decrypt, them make the actual request to the host, then get the return traffic, encrypt it again, send it back to you, then your machine must decrypt it. That is a lot of extra travel time for a data packet, plus add in the time for encryption/decryption, plus the server you use is not dedicated so its resources are shared amoungst many others doing the same thing, then also figure in the VPN provide has a set amount of bandwidth as well.

VPN is a tool, not an end all solution.

Tor is another tool that provides a different type of anonymity. Slightly different than a traditional VPN.

Basically, yes, IP protocol stack is essentially the same. All these devices can communicate to each other.

IT's when you get into the apps that rely on that stack that you start to have issues.

Right now, I have MACs, PCs, Ubuntu, my Android phone (over wifi) all speaking to each other using ICMP and more importantly, SMB for file sharing.

IMHO, there are plenty of $5 per month VPN services out there. You can use the VPN service to encrypt your traffic between your computer to the vpn server so no one can read it (i.e. the isp). The vpn server will relay your web request so that it looks like the vpn server is the one making the request. The info is returned to you over the vpn tunnel.

Make sure you pick a VPN vendor that does not keep logs.

I use these all the time.

From your Computer, can you access the nas via IP? START - RUN - \192.168.1.10 <- whatever its ip happens to be.

If you can hit is this way, then the nas may nto respond to broadcast discovery and you would need to add a hosts/lmhosts file entry to resolve the name to ip.

Ditto that. You may want to try copying the tar file into your home folder and unpacking it there to see if it works. If it does, then it is probably the lack of write permissions in that mounted file system.

Agreed that this is very subjective.

Python is my choice whenever I'm looking for something more than simple backups or file manipulation. HTMLperson5 is correct in that you want to stick with python 2.7.

BEst thing about python are the libraries of add-ins. Whatever problem you are looking to solve, chances are someone has already shared a solution that you can include in your solution.
