Plug&play Switch Appearing As One Device
Jun 11, 2008
what network device would suit our needs (and whether there is something like what we need).
The device should meet following criteria:
-it should appear as one device only: a L2 switch is not an option as the device has to announce only one MAC address on the uplink port
-plug&play: a gigabit L3 switch is not an option because we would have to change the default gateway of the already configured servers to the L3 switch's IP
-gigabit ports
Is there any reliable device that could be used for this purpose?

I can only assume that I have a virus or adware on my server but Acunett says that there is nothing. I double checked all of my email sending php scripts and all of them are secure and not sending any spam. However in my mail queue in WHM I see spam emails and my server's IP keeps getting relisted on the blacklist located at:
[url]
AM I THE ONLY PERSON IN THE WORLD WITH THIS PROBLEM? This is getting frustrating I have probably spent over 200 hours trying to get this resolved but it seems like no one knows what to do. This is hurting my business since I have tons of emails stacked in my queue and being blocked by email providers due to that blacklist. I remove my server's IP successfully and the next day it is blacklisted again. If anything how can I check my linux server for viruses?

When i add a new domain to plesk, it puts in the correct Name servers in, but it also adds the computers name into the list and when getting it checked out from intodns.com it flags it saying missing Name Servers.
Into DNS : [URL] ....
I have also attached a screenshot showing what DNS Manager is showing.

We're working with a new Plesk 12 server, I have migrated a bunch of sites from an old server, and all SSL enabled sites and certs have come across correctly, however if I add a new site, and SSL cert, the cert is not selectable at domain level, and is not being served at all.
My process is:
At settings level - create new CSR and enter certificate received from provider.
Then select this cert on the IP address management screen.
This has always worked, and presumably still should. But at domain level, Plesk is only allowing me to select the default cert. And even though I have linked the cert to the IP, it is not being served to browsers.

I have SSL enabled site on IIS.I want to access it from my PocketPC(Win mobile).But when I try access it, I have been prompted to install a certificate.
Unlike when I try to any HTTPS site (Banking sites) I have never been prompted to install any certificate.
Why am I being prompted with security message with "Yes,No,View certificate" options on it every time I try to access my own server(desktop) via my WIN mobile using active sync.
Unlike When I try to access banking site(https) I was never ever prompted a mesage like above.
How to have same functionality for my application also?

I have a Dell LTO-4 tape device, its not an autoloader, just a single drive.
When backing up using NTBackup, the backup to the first tape is sucessful, however, the backup wont fit on one tape, so it prompts me to tell me the media is full.
I insert new media, but NTBackup doesn't notice its there, so i go to Removable storage, click libaries, right click the tape drive, and click inventory.
This makes NTBackup detect the tape, and asks me if i want to use it. I click yes, but then i get an error message come up saying it was unable to mount the media, invalid command, and the following gets logged to the report:
Code:
Cannot locate the specified media or backup device. This backup operation will terminate.
----------------------
Cannot locate the specified media or backup device. This backup operation will terminate.
----------------------
Cannot locate the specified media or backup device. This backup operation will terminate.
----------------------
I have read many microsoft articles that explain tape drives having problem with automated backups because the user inserts a new tape, but ntbackup isn't aware of it. But that seems to be related only to scheduled unattended backups.
In this case its when the first tape is full and it prompts me for the second tape.

Have been having some problems lately with some of my IPs and clients using unauthorised IP addresses which the ISP is hopping on me about it.
I have tried things like
In LINUX
nmblookup
nslookup
In DOS
nbstat
but can't get the MAC of the particular IP I am looking for...

programatic/scriptable way to find out which disk a file is on. For example, if I look at the output of: stat /root/.bashrc I see:
File: `/root/.bashrc'
Size: 1298 Blocks: 16 IO Block: 4096 regular file
Device: fd00h/64768d Inode: 13991942 Links: 1
Access: (0644/-rw-r--r--) Uid: ( 0/ root) Gid: ( 0/ root)
Access: 2008-05-18 09:19:14.000000000 -0400
Modify: 2007-12-18 09:19:54.000000000 -0500
Change: 2007-12-18 09:19:54.000000000 -0500
So I can see this is on device 64768, but how do I get from there to knowing that 64768 is really /dev/sda1, where in this example, I know the file actually is?
Overall, I want to resolve from the filename which device in the output of iostat contains that file - I don't necessarily have to go through stat, but it looks like a promising starting point.

We have a customer requirement to enable Direct Push email on our Outlook Web Access servers to a number of mobile devices the customer will be supplied from Vodafone - running Windows Mobile 5
Therefore we need to create a public HTTPS address to allow access to the OWA/OMA part.
We do NOT (at this stage) want to allow general access to OWA over HTTPS (we have an eGap solution with RSA for this) so we need to be able to lock down access to the OWA server only to specific devices. One way would be to use Firewall Rules at the Outer DMZ and lock down by the IP ranges of the phone but thats prohibitive to other devices and will fail when the phones change IP (i.e. international roaming)
Therefore Im wondering if we can use self signed SSL certs where there is no trusted CA provider (if there was all browsers would simply be prompted to trust the source and then get access). If we use our own self signed certs and have them installed on the client devices would this work? What would be the downsides (i.e. less cryptogrpahy without the CA part?)

I run some tests with an Apache 2.4.10 running on W2k3 Server to see if Videos are playing well. The site is protected with .htacess/.htpasswd for now. I use jwplayer as player. The videos run fine on FF and IE, but as soon as I want to play them on an IOS 8 device (Iphone, Ipad), it doesn't work anymore. The message I get is "File cannot be played". The odd part is - when I remove .htaccess/.htpasswd, it works immediately. IOS devices, or is there something specific to be set to make this work? I logged in to the site with user and password, which always worked flawlessly. I assume it's not an Apache problem, since it runs fine on FF, but maybe someone here is aware of such a bug or something.

I am getting this error on my site. I have googled this error and it is telling me it relates to a /temp/ folder of some form. I am currently on a hosting plan (not a dedicated server). Is there ANY way I can access to fix this problem either from my control panel or by code?

OP: Linux Centos
I just got an additional 500GB hard drive added and mounted it to /home2
There are files that are in /home1 (orginal HD) that will need to be constantly moved over to /home2 via a ftp
But i keep getting this error
550 Rename/move failure: Invalid cross-device link
Does anyone have any ideas? I tried changing permissions but no luck also tried mounting the 2nd hard drive within a directory in /home1. Still gives the error.

So I have a script running on my apache that catalogs pictures and clips. All the actual video files are located on a separate drive which is mounted in to a folder in my site. I've set apache as the owner and have the correct permissions on the mounted folder but I'm getting Forbidden errors accessing files even when on html file in the mounted folder.
I know it's a permissions issue at the disk or mounting level. The way I mount is by using this command:
mount -t ext4 /dev/sdc /var/www/html/media

I currently have a dedicated server, which is hosting several websites. I'm happy with the service I'm getting, but I'm trying to save money. I'm paying $120/month for the dedicated server. Spending half of that each month would be great.
Right now, the websites are either static websites, or are simple database driven websites with not much traffic. My server load averages are pretty close to 0.01
I would think a VPS would be fine for my needs. However, I may have a site I will host in the future that is database driven and uses Ruby on Rails. It would probably have 10-20 users online at any given time, and maybe several hundred subscribers total.
Would a VPS still work in this instance, or should I stick with a dedicated machine?
