Mutahir's questions

I have a broadcom bcm5709c quad port nic (gigabit netxtreme II); I download the broadcom utility from there site, I can setup teaming and all, but I can't seem to find the setting to enable jumbo frames at all ?

Can you please assist or provide some pointers as to where I would enable this setting ?

OS is Windows 2008R2 Enterprise Edition 2 x Quad Port Broadcom BCM5709C NICs.

Thanks and will look forward to your suggestion

EDIT :

Here is the screen shot, I have broadcom control suite application 4.0 and I can't seem to find the MTU / JUMBO setting in here, it shows me the MTU = 1500 in information tab but no edit option.

Do you think i should download the drivers from broadcom and install to see if that helps ?

I need to create a folder structure via command line, structure is as follows :

username > folder1 > folder2 > folder3 (and there are subdirectories within these folders as well)

This is a windows host, I have done "dir /ad > dir.txt (It outputs the parent folder)

Also, which command on dos would I use to create folder from text file ?

I have used xcopy /T /E (it fails at a certain point as the files are being read from these folders majority of the time), I have around 1500 folders and then sub-folders within these folders.

I have a Dell 2950 with MD3000, MD1000 ; Suddenly the I have lost all drives on both of the enclosures and all drives on the MD3000/1000 are blinking, but only ONE Light on each disk, not 2 Lights.

I have tried dell doc and can't seem to find this light status code so far, will be grateful if someone could assist as to what may be the cause or have I lost all data ?

This is a lab environment and the data on it is mainly file shares for our in-house staff.

we can afford to loose data but there are some folders which we would like to recover if possible.

If for example : (a) The SAS Card is dead, can we just replace the sas card and we would get our data back or are we done :-)

Important Update

``I have just checked the Raid Logs - it says "Media Scrub Scan Completed" and right after that it says Event Type 2023 : Virtual Disk Deleted

No one has deleted the virtual disk, I have tried changing SAS Cards, MD3000 Raid Controllers, SAS cables but MDSM always shows Physical Drives and shows No Disk Groups or Virtual Disks.

Any thoughts ? Will be grateful

a) Can I export all users irrespective of there group memberships to a CSV File, for e.g. users.csv ?

b) Can I also export all OUs to a CSV, so I can later re-import them into a New DC on a New Domain ?

c) Can I export all Groups to a CSV, so I can re-import them into the New DC / New Domain ?

Basically, we have a lot of users, groups, OUs, we are just testing to see if we had to manually re-create all users, groups, ous, via CSV files ?

is this possible ? Will be grateful if someone could provide a script / command to get there.

Thank you all for your suggestions, I think I may have not explained my Question better. Basically, I am not doing or wish to do this for Backup purposes.

I just want to see how this works, for e.g. : If I manually create a CSV file with a list of say 20 or 30 users, what would that csv file should be like ? I mean attributes or fields so that it can be imported into AD with one command or script?

So, I thought if one would export first they would know which attributes would be necessary to create accounts into AD.

Now, the question is :-) :

a) How to create that CSV File, what fields are required?
b) Can we set a Default password too for those new accounts?
c) Can we also specify which OU to create that users in or I can move them later?

I hope I have asked clearly this time, it's not meant to be a backup of any kind, just a way to create multiple users or move multiple users around with ease.

Thanks again for your input.

I have a cisco router with 4 ethernet interfaces, scenario is as follows :

2 x Dedicated Leased Lines (2MB and 4MB) 1 x Business Class DSL 10MB

4 3COM L2, Switches, connected to a Core Switch (3COM - Layer-2)

Core Switch Connected to 1 Ethernet Interface on our Cisco Router

I am now tasked to configure load-balancing so that our LAN Users can utilize all 3 WAN connections

Googling turned out that I would have to use BGP amongst / with service provider (not possible)

Question is :

a) If I cannot use BGP, do I have to use Policy Based Routing (PBR) or is there any other solution considering the above scenario and cisco router 3700 Series ?

b) Also, How would I enable QOS / Traffic Policing in this scenario? Would that apply per interface or globally - any configuration example would be really helpful ?

c) PBR is not load-balancing ? Right ? (My understanding, is that it simply routes a set of IP Address from one interface and others from another interface as configured ?

Will be grateful for your suggestions and help on this

Thanks and regards

We have AD on 2008R2 implemented and working fine. We have ONE Forest and 3 child domains city1.domain.lan, city2.domain.lan, city3.domain.lan with rootdc.domain.lan being the forest master. Forest functional level is Windows 2003.

I have recently inheritted this setup and my initial findings reveal that the child domains are not resolving DNS name lookups for external requests, rather the previous sys-admin was distributing DC IPADDRESS, 8.8.8.8 and 4.2.2.2 as DNS servers.

There are no forwarders configured on the DC DNS MMC, moreover the DC cannot browse the internet due to security reasons, they have a VPN tunnel connected to root site for replication but all other traffic is disabled on that circuit - so no internet connectivity for the DC itself - hence no external DNS lookups.

As they have around 500 - 700 Users and considering everyone is getting 8.8.8.8 and 4.2.2.2 for external dns lookups, I am thinking that would be a lot of requests going out there Internet Link for DNS (53).

Q1 - Do you think I should implement a windows based DC joined to the child domain for external look ups or the above setup seems ok?
Q2 - What do I look for to verify whether the DC is replicating fine (repadmin ?)
Q3 - I checked Sites and Services but I am not very good in AD and have to learn - so would be grateful if you could let me know what to look for ?
Q4 - I used AD topology diagrammer and it says Intersite Replication disabled ? Is this harmful ?

I will post more details about the AD topology and if one could let me know what to provide as info - I will do my best to get the question updated ASAP

Your help would be grately appreciated
Thanks !!

I have a Windows 2008R2 DC (Just setup), we already had around 25 Windows 7 professional / ultimate clients, which we are now going to join to our new domain / dc. Users were already using the machines and were Local Administrators on that machine.

I want to deploy a USER via GPO which can either get created on every LOCAL windows 7 box and have Local admin rights or a Domain user which has LOCAL admin rights on every single PC on the domain (Windows XP, 7).

Will be grateful if someone could assist on this - I did tried my self creating a user but it won't get created, I used the Computer Settings group in GPO Edit to create the user.

Thanks for reading - will look forward to your guidance Rihatum

We have decided to test and then deploy a Forefront TMG server on our network of 50 - 75 users (Windows 7, XP Clients, Windows Server 2008R2 Servers and a few Linux Boxes)

Our Network Topology is :

4 Floors (4 Lan Switches) > Connected to a Core Switch in our Server Room > Core Switch Connected to our Cisco Router on FA 0/1 > Cisco Router FA 0/0 Connected to our ISP (WAN).

At this moment our DHCP is running on our cisco router and it is also the default gateway for our LAN : Default Gateway : 192.168.1.1

My Question is :

TMG Server has 2 NICs (One is Connected to our LAN Switch - TMG NIC IP : 192.168.1.200)

During Forefront TMG Installation, I added the range 192.168.1.1 - 192.168.1.254 on Adapter Selection during installation,

Once the install completes, how shall I redirect my clients, so that all network and internet traffic goes via TMG NIC 192.168.1.200

What IP Shall I assign to the 2nd NIC on the TMG Server ?

Where shall that 2nd NIC be connected ?

Shall I place TMG Server with DUAL NICS between our Core LAN Switch and Router or Behind the Core Switch ?

Will be grateful for your assistance on this, we would use this for content filtering and web blocking and other features.

Thanks for reading !

Thank you for your reply : I have more then 3 questions now :-)

Q.1 : If I have 3 ISP Connections and 4NICS on our TMG Server, Can I connect all of them and have TMG Load-Balance / Failover them ?

Q.2 : Can TMG Dial a PPPOE Connection ? say All 3 ISPs require us to dial a pppoe - is it possible to configure that for each nic ?

Q.3 : We also have a Cisco router acting as our WAN Router at the moment, only plugged into 1 ISP, When I configure TMG to loadbalance all 3 WANs, shall I just remove cisco out of the topology or how would I connect TMG and Cisco? A bit confused here - will be grateful if you could assist on this - if this is possible.

Q.4 : If I had ONLY 1 (ONE) Nic on our TMG Server, would it connect to our LAN Switch and then we would specify its address on our W7 / XP Clients so it acts as a caching server / web filter ?

Q.5 : How do we route all internal internet traffic so that it only goes through our TMG server - if we were to use this for caching and web filtering only ?

Once again thanks for your reply - I am just testing this at the moment, I have setup an AD 2008R2 Box, TMG is joined to the domain and has 4 Network Cards installed and configured. TMG is currently plugged into our LAN Switch

I have a department of 20 users or so, which basically work in shifts but access the same desktop and settings, I am thinking to join these computers (15 computers) to AD and create only ONE account for e.g. ContactCentre, so that they can authenticate against AD and have the same settings.

Question is, can a AD account login simultaneously from different machines or would it be a problem ? Any other suggestion in this scenario would be very helpful.

I am somewhat comfortable with Linux / opensolaris command line options but not very good.

I am trying to build a Storage based on ZFS, the specs are:

• Dell 670 Machine with 4 Hard Drives (SATA and IDE)
• I have downloaded and created Open Indiana USB and can boot live and install
• I have also seen napp-it (http://www.napp-it.org/index_en.html) and have installed it on Oracle Solaris Express (Personal Home PC)

I am a bit confused and have a few questions:

1. Boot / Install Disk is separate, and I have extra 4 attached internal Drives, when I do the installation how do I form a Pool including all 4 drives?
2. If I go the napp-it way (which seemed easier to me) and form a pool of all 4 drives via web gui, how can I share it to my Windows machines over the network, I have two iMac (Apple OSX) as well.
3. Is there a document I can read about ZFS and how to handle / maintain it?
4. Any other recommendations you think will help?

I am really tempted to install zfs NAS on openindiana and will be grateful if some expert can provide a step by step either command line or napp-it web gui - including setting up sharing with windows, osx clients.

Now, it is my first time with Linux and a SAMBA File server. I am using the TurnKey Linux File Server Appliance.

I have installed it native on my new fileserver machine (an OLD Dell 670 Workstation 2GB RAM and 2TB x 4 SATA) I can access webshell, webmin, extplorer - all good, but :

My Scenario is, that I want to have the following Groups of users, namely (HR, EXEC, IT, Marketing, Sales, Production) ... I will then create users individually and add them to there respective groups.

for a test, i created a HR group and add our HR person to it, they can see the share listed when they connect from a windows machine but they can't create anything inside it.

I clicked on the option "synchronize UNIX user and samba user" and synchronize UNIX group and samba group as well.

Also, I have active directory, what is the real benefit of binding my file server to our Active Directory and how reliable is that ?

I will have a few more questions which I will post once I have tried and failed,

will be grateful for your assistance on the above Kind Regards

I am planning on installing openfiler (first time) on a Intel Core2Duo 4GB Ram with 2 x 2TB Sata Disks.

Do I need to install openfiler on a separate disk and then use 2 x 2TB as Data drives, or can I install Openfiler on the Primary (1st Disk) and still use the remaining space for my data.

This is for 50 users maximum on a gigabit network, the machine would have a single gigabit nic.

Or

Shall I try to setup Opensolaris (oraclesolaris express or indiana) as a NAS box using ZFS ?

Will be greatful for your insight and suggestions ! Kind Regards

I have the command below in a windows batch file, whenever I run the above batch (ipconfig.bat) to get the ip of my linux vm, it outputs the ip fine but doesn't ends the batch file, I have to press control + c and then press "y" to end the batch file. Even after adding @exit it doesn't exits.

VBoxManage --nologo guestcontrol execute "nixvm" "/root/scripts/ipconfig.sh" --username root --password mypassword --verbose --wait-for stdout @exit

Any suggestions ?

The Bash Script (which gets executed by a windows batch file)

#!/bin/bash
echo "IP Address of "LinuxVM"
ifconfig eth0 | egrep '(inet addr|RX bytes|TX bytes)'
sleep 1s
#echo "MySQL Service Status"
service mysql status
chkconfig mysql --list
sleep 1s
#echo "Displaying MySQL DBs"
mysqlshow -uroot -pmypassword

Windows Batch File

VBoxManage --nologo guestcontrol execute "LinuxVM" "/root/scripts/ipconfig.sh" --username root --password password --verbose --wait-for stdout

I have a bash script which downloads a sql.gz file, extracts it and then import it, however before importing, I drop the existing DB, then import the new DB onto the server.

All is well and the script does what it is supposed to, only one thing :
I have this statement in my bash script :
mysqladmin -uroot -ppassword drop dbname
which then waits for user input to press y or n to continue.

Is there a way I can input Y so it always says yes and automatically completes the script. I am new (v.new) to bash scripts.

Thanks Kind Regards

Exported Virtual Box VM (CentOS 5.5 with Guest Additions Installed) - Success
Imported CentOS VM Successfully on another Windows Machine via Windows Batch

Problem :
VM After Import retains the same Mac Address and gets the same IP as it was exported from, is there a way one can either change / flush the IP & MAC while exporting or after Importing ?

a VBoxManage command may be? Which I can put in a batch file after import ?

Will be grateful for your assistance on this Kind Regards

Oracle VirtualBox on Windows

Hi All,

Is there a way to start a vm headless (vboxheadless -s ) but one can close that command window or if I add that as a startup item will that make it run silent ?

I have successfully exported a appliance (linux vm), when I will do the batch import will it retain the settings I had configured originally or will one would have to assign bridged adapter, amount of ram, etc ?

will be grateful for your suggestions ! Kind Regards

EDIT : Iain, if one wants to script the GuestAdditions install on first boot in a CentOS VM, shall I just put the commands ./VBOXLinux-x86-additions.run to the bash script and it will run at startup, any thoughts on this would be really helpful.

Kind Regards

VirtualBox on Windows

I am planning to deploy virtual box on around 10 computers (Vista / 7), I have setup a centos vm and exported it as an appliance with the ovf and vmdk files in the same folder.

Question Regarding VM Deployments :

Assuming VBOX is installed on the desired Machines already (latest version) Exported Appliance is on a network share Can I windows batch import it into vbox from the network share - what will be the vbox command/s in windows batch I would have to use to get this done?

any suggestions or if someone has done the same any best practice or things to look out for?

Kind Regards

Exchange 2007 on Windows 2008 Server Circular logging enabled

Exchange aware Backup Application (Symantec BESR 2010), on test restores, when I do eseutil /mh on the mailbox database, its in a dirty shutdown state.

I am thinking that it is because of circular logging, as I did a test backup on another exchange box which has no circular logging enabled and the logs were truncated by the backup app, on a test restore the db was in a clean shutdown state.

am i right in thinking that I should disable "circular logging" (logs will be truncated by BESR 2010 -it has the option) ?

Now, can I disable this in production hours ? is it just a matter of unchecking the box and the change effects straightaway ?

Thanks & Regards

I have a Exchange 2007 SP1 server running on Windows 2008

6 HD Drives in a RAID-1 OS, DB, Logs on separate RAID-1 Disks

Size of the Mailbox Database is 183GB and increasing

We only have First Storage Group and Second Storage Group

There is no more space on the server to install new Physical Disks and create a Storage Group

Q - Can I resize the RAID-1 Partition where the DB is ?

Q - Any other suggestions as to how I can decrease the Mailbox DB Size ?

Will be grateful for your suggestions on this.

I have to install wordpress (One Blog, one domain, for e.g. mycompany.com/blog) on two servers sharing one database on a different server, these two servers are behind a loadbalancer and the db would be on another server. We are planning this way due to high traffic.

I have done standalone wordpress installations on a single server, on windows 2003, 2008 with IIS6, 7 etc

I am just researching as to how would I implement this.

What would be the steps to achieve this and upon searching I saw some posts regarding the wp-content/uploads directory to be synced at regular intervals ?

your help much appreciated Thanks for reading

What we did :

a) We have two web servers connected to a san cluster b) created a blog directory on the san c) Mapped that blog directory as a virtual directory on both webservers d) Installed wordpress on any one of them (as the domain and IIS virtual directories is the same for both servers - for e.g. www.abc.com) e) Database for this blog is located on two MySQL Boxes

as Wordpress is sitting on the san, so no conflicts with uploads or anything like that, Blog url is www.abc.com/blog and that's how it is configured on both.

Hope that helps someone !
