hello guys, it is me again with a new topic

what is better in term of performance and redundancy : software NAS (like freeNAS) or a hardware NAS ??

Hi everybody

I want to set up a voip system (just learning purposes) and i want to use a free IP PBX like Elastix or freePBX or any other asterisk based IP PBX, i have one POTS line, i learned that i can connect my IP PBX to the PSTN and make outside calls via a PSTN gateway (linksys SPA3102), according to what i wanna do, what is the best asterisk based IP PBX that play well with POTS lines ?

Hi everybody

i have a file server windows 2008 R2, i setup a daily scheduled backup on it (but the backup is made locally : backup D:\ to E:)
my concern is : i risk to lose everything if the HD get damaged because the data and backup reside on the same physical HD.
you may ask me why not changing the backup destination to network shared folder ?? i will tell you that if i select network shared folder: i will have only one backup at a time (each day the new backup overwrite the previous one) not like if i select local volume (i can restore at any given time)

my question here is : if i buy a DAS (direct attached Storage) and connect it with my file server, does the Windows Server Backup consider it as local volume so that i can select it as backup destination and allow me to have daily version of backups or it will consider it as network shared folder ??

Hi everybody

what is the latest version of CCNA Exploration, i studied CCNA exploration V4 but till now i didn't pass the exam for certification, is there any difference between old and new version of CCNA, if yes what are the main differences ?? and the link for downloading the course ??

thank you very much

it is a better practice to create OU for computers and OU for users, this separation will help you in dealing with computer and user configuration, then create and link group policy to your OUs, you will get a nice AD structure

i want to take your advise regarding the following setup :
i want to setup hyper-V in a desktop machine with the following characteristic : core 2 Deo 2 GB Ram and 250 GB in HD knowing that i want to host in it only 2 light VM (freePBX and pfsense) and this server will serve only 4 users

is it possible to do so ??

Hi everybody

i have vmware installed on my windows machine (hypervisor type 2) and i have one vm installed on it (configured freePBX) and i want to import/export to hyper-V hypervisor, can you give me some enlightenment regarding how to achieve this ??

Hi all
i have a xenserver hypervisor with 2 nic, i installed 2 guest : pfsense and freePBX,
for pfsense everything is OK, he recognized both nic (LAN and WAN)
the problem with freePBX, i want it to have one nic and it must be connected with the LAN of my pfsense, in other word i want the freePBX to be behind pfsense,
how to achieve this in XenServer ???
thank you for your help

hello everybody

i put myself in trouble when i decided to have an additional DC in my Domain, before this catastrophy i had 2 windows server 2008 R2, one of them is DC and the second one is an application server with multiple SQL server instances and databases,
i decided to promote the application server so that i have a backup DC, after promoting it some of the application installed on it stop working cuz the connection btw the app and database is failed,
i never thought that such transition from stand alone server to DC will cause this trouble, because the SAM account were deleted and i think the databases were configured with these local admin account,
now i demote the server application but the SAM accounts were all deleted, only i have 2 account : administrator and guest, the other account were all deleted.
now i don't know what to do to recover this,
is there any way to restore SAM accounts ???

wow, i run it on my Win 7, it shows me the key

yeah it is great to know the end result of a problem or a project,

I have a question regarding Veeam recovery media, as you know during Veeam installation, Veeam create for us a bootable USB to recover the system in case of disaster, I want to know whether I can use the same bootable USB to boot other machine or it is limited only to one machine (that created it) ?

@scottalanmiller said:

I have a suspicion that you are completely misreading what that quote says. It very clearly says that you should NOT have lots of images, only one (because it is not recommended to have multiple OSes or architectures.) It shows that you were mistaken and should have just one 64bit image and put all of the drivers on it.

lol, sorry again my poor english confuse me, now it is claire for me

Hi everybody

i bought one NAS WD my cloud EX4 12 TB, i have a core cisco switch (1 Gb/s) and when i copy paste from my server (having NIC 1 Gb/s) to my NAS (having 1GB/s) i get a low speed of max 5.5 MB/s

i cannot understand why i get such speed 5.5 MB/s ~ 44 Mb/s while i have 1Gb/s infrastructure ??

thank you guy for any information

ok guys thank you very much, i will install xenserver as i do previously with my computer (i need only to enable VT on CPU)

Hi everybody

i have xenserver Host with 2 NIC, i installed 2 VM on it, i bridged the 2 PIF to one VM , this VM has now 2 VIF, VIF0 bridged with PIF0 and VIF1 bridged with PIF1,
PIF0 is connected to the LAN, PIF1 is connected to a mirroring port on the switch (sniffing all traffic ti record voip calls)

i have already execute the following command :

xe pif-param-set uuid=<uuid_of_pif> other-config:promiscuous="true"
xe pif-param-list uuid=<uuid_of_pif>

xe vif-param-set uuid=<uuid_of_vif> other-config:promiscuous="true"
xe vif-param-list uuid=<uuid_of_vif>

xe vif-unplug uuid=<uuid_of_vif>
xe vif-plug uuid=<uuid_of_vif>

i tried both :
xe-switch-network-backend bridge
xe-switch-network-backend openvswitch

it is so frustrating, i spend hours in this
