Would you rather have your firewall hosted or in house if you've got the skills to manage it?
What are to pros and cons of having a firewall hosted by your ISP in general?
I just upgraded to IE 8 on our Terminal Server, but it asks everyone for search engine, turn on/off suggestions, etc.
Is there a way I can force one default setting for everyone through Group Policy?
I have installed Free XenServer on 2x HP DL360's, one with Quad-core CPU and another one with 2 Dual-core CPUs.
When I tried to join the Resources Pool I got an error
The hosts in this pool are not homogeneous. cpus differ
Citrix Resource Pool Requirements
each CPU is from the same vendor (in particular AMD-V and Intel VT CPUs cannot be mixed)
each CPU is the same model (except for stepping)
each CPU has the same feature flagsIn practice, it is often difficult to obtain multiple servers with the exact same CPUs, and so minor variations are permitted.
How much can CPUs differ? Can I mix quad-core and dual-core machines and force them to join the same Resource Pool or is it only CPU clock speed which can vary?
I have a Cisco switch 3560 with a router for private VPN plugged into it. Unfortunately I don't have any kind of access into this router.
I'm going to set a local SPAN and mirror all traffic to another port where I'll plug my sniffer.
I need to generate graphs that will show me what kind of traffic is going through VPN.
Preferably some Linux freeware application which will provide me graphs (something like Cacti) but I need more specific reports with ports and IP addresses.
Is Ntop what I'm looking for? Will it work the way I want?
Lets say you don't want anyone to be able to log into your windows profile.
I like to save passwords in my web browser.
However, I'm not the only one who has a domain admin account. Someone else can just reset the password in AD and then he/she would be able to log into my machine.
How can I prevent this?
Is there some application which can force an additional login or
some other free solutions?
EDIT: Thanks for your suggestions, I meant additional security in general without focusing too much on web browser passwords. Looks like encrypted home directory will solve my problem.
we have a problem on our Exchange server 2007.
I have currently 300 undelivered emails to various addresses. I'm getting this error message
421 4.4.2 Connection dropped
I checked the size of attachments and the messages aren't too big (20 KB to 6000 KB). From 200 mails to various emails addresses 137 weren't delivered.
We don't have any problems with incoming emails, but 20% of outgoing emails just sit in a queue.
Is this a DNS issue ?
I got a job to migrate 2x BIND DNS servers to new hardware.
Apparently they are using 3U prehistoric servers running Ubuntu server 8.04.
I'll get to install 2x 1U servers with Ubuntu server 9.04.
How can I transfer DNS settings, DNS cache? What folders/configuration files do I need to transfer?
Will I achieve anything if I use Webmin > Backup configuration > BIND DNS server or should I avoid using Webmin?
I've inherited this stupid name convention:
COMPANYNAME-CITY20090724 or COMPANYNAME-CITY-JOHN
It doesn't tell me anything about the location (floor, department). John left the company months ago. Computers from one city moved to another city, but the name hasn't been changed.
How can you rename 100+ computers when you want to create a new naming convention?
How do you find out who is logged on to remote windows machines?
I'm using psloggedon at the moment, but it gives me only one computer at a time.
psloggeon \\172.21.0.5
Is there a better way how to scan a whole subnet ? Preferably some GUI application.
Unknown error 0x8004011B appears after an Outlook Send and Receive operation.

I looked at these with no luck so far.

It has something to do with the Offline Address List, the Global Address List doesn't update.

We use squid 3.0 on Centos5.3 and have currently 20 users (Internet Explorer) using this proxy. The problem is that the access through proxy is slower. Even a simple webpage like google.com(.au) takes 5sec longer than a direct connection without proxy. Looks like there is approximately 2-5 second delay. Disabling cache for google.com(.au) didn't help. Explicitely defining dns_nameservers makes no difference.
Server parameters : Dual-Core AMD Opteron(tm) Processor 2220, 6GB memory, 60gb SCSI hdd
cache_mem 256 MB
cache_dir ufs /usr/local/squid/var/cache 30000 16 256
maximum_object_size_in_memory 256 KB
minimum_object_size 0 KB (0 - 200 KB - not a real difference, the delay is still there)
maximum_object_size 32 MB
How would you change these specifications in squid.conf based on the server specifications. What can cause the delay ? Also for a bigger webpage like yahoo.com.au is there a way to receive a part of the page from cache and then the rest (images last). At the moment there is nothing for 15 sec and then a whole webpage appears.
