Have a 2008 windows domain and am looking to add a storage server to house graphic files that need to be shared between MAC's and PC's (Windows 7 pro). Not sure what OS to install on the new server? Windows/Ubuntu/Samba (the new server is a Dell box so IOS is not an option.) Is there a better option?

Thank you

Unable to boot new Fedora linux or Windows with new installation, after Fedora 27 was installed:

I have 2 one Terabyte each hard drives in my system:
Hard Drive 1:     /dev/sda1  has Windows 7 on it
                          /dev/sda3 has Fedora 27 installed

Hard Drive 2:    /dev/sdb1   is a 2TB NTFS Storage partition with no operating system on it.

See photos of partitions showing  from GParted partition manager:
sda device (Hard Drive 1)sdb device (Hard Drive 2)
I was trying to fix the problem with 'Boot Repair Disk' from
http://www.majorgeeks.com/files/details/boot_repair_disk_64_bit.html

This is what it is telling me, and I don't know what this means:
Enable Grub Repository Message
Would I need to do it from Fedora 27 running from a boot DVD?

How would I do it from the command line there?

What else can I do to make my system bootable?

Thanks for your help.

build a samba wins server on and old pc using Linux distro with a sambal gui
and make it the master browser

So, I researched the idea a bit and, it appears that if one were to introduce such a server, it could be connected to the network and take over name service.

Could it be turned off to return to the original "normal"?  That would seem to suggest a very low-risk approach in dealing with LAN single-subnet name service that would be reversible.

Could such a server be set up on a virtual machine?
I have thoughts of setting up a virtual machine on an existing Windows workstation for this purpose.
Seems like this would be the least intrusive approach to a critical system that's in production.

Your thoughts and suggestions would be appreciated.

Hi all,

I am having a serious problem hosting websites based on Redhat or Centos on Hyper-V.  While on physical server that is not the case even when the CPU and memory is much less than what is been allocated for on Hyper-V.

30 - 50 user's try to access a page to upload document or login, the server gets hanged completely.  sometime we have to force restart because we cannot even login to reboot the server.  but that is not the case with physical server even when the memory and CPU is half of what is been used on Hyper-V.

One of the issues I am facing on Hyper-V is the memory releases, which keeps increasing and never get release unless I use a run /bin/sync; /bin/echo 3 > /proc/sys/vm/drop_caches on crontab to release the memory or force restart the server.

I am getting to a point to move all my web onto physical machine due to that problem.  can you please help me resolve that problem.  Is the fix from the Windows, Linux or Apache?

I am trying to install multiple mediawiki farm sharing same resources (4 in total), exactly like Wikisource.org, on Amazon Web Services EC2. This installation will consist of the main wiki in English (wikiexample.org), two languages sub domains (lang1.wikiexample.org, lang2.wikiexample.org) and a commons hosting their media files (commons.wikiexample.org).

The wikis will have the extensions of Wikisource like ProofreadPage, PDF handler, Djvu extension and the Translate extension.

It should be possible to maintain and upgrade the entire wikis centrally and not one at a time.

Can anyone please put me through how to go about this?

Thank you.

I have a Linux server and I would like a PHP script to monitor a list of websites to check if they are active. For example I would like to check for any websites returning a 500 internal server error. Upon detecting this error I would like an email and SMS notification sent.

I understand the script needs to be called either by a CRON job or internal scheduler on a regular basis such as every 5 minutes.

I wish to reiterate that the websites being monitored are hosted externally on a Windows server but a Linux server will be used to do the monitoring.

I have a Linux server that is constantly maxing out CPU usage on my daily SolarWinds monitoring report. I checked the box out and it is part of our network team. They call it a "Radius/Tacacs and NAC. Networking asked me if I could just simply add my CPUs, so I checked out the configuration and it is configured with 6 virtual sockets all single core.
I doubt it is as simple as just adding CPUs. If I had set up this server I would have probably done 2 slots/2 core per slot, but that is only because that is how I have seen other virtual Linux boxes configured in the past. Can someone give me some suggestions and how I can prevent CPU from maxing out on this device? I know this is kind of vague but any trouble shooting suggestions would be welcome. Also does adding CPUs affect licensing?

we have a few servers in the cloud (AWS) ...i find that the one or the other server has rebooted  ...many a time am not able to
find / gather what has caused a server reboot from the logs ...except for the fact that the server rebooted at a particular time.

I would like to configure my server in such a way that ...it would log the cause of  reboot ...next time it reboots.

would appreciate pointer's , hints or a detail procedure on how to achieve this. (i.e. the configuration to be done on server should help in achieving the RCA ...root cause analysis to be  determined  fairly  from the logs without missing any information.) ...viz. all the steps to be done so that vital information is not lost and is captured to find the facts.

also to clarify i don't notice any  core files captured on the systems.

as on date all the systems are production systems and they are not configured to capture a crash ( coredump )  or debugging info i believe ....kindly let  me know is it mandatory to enable capturing the crash / core  ...if so steps to do it as well

Dear Experts,
I have an Exchange 2013 server and I am experiencing connectivity issues using Telnet on port 110. The problem started with the expiration of the SSL Certification. It was renewed in time and all other exchange services continued without an issue.

So far this is what tests have been performed:

- PopProxy (this was inactive at the point of investigation but has been started)
- Pop3 service (has been restarted)
- CU18 has been installed
- Logging has been enabled and this is the recurring message, POP320180111-1.txt:

Hi I have just installed a FOG server on an ubuntu machine. We have Fujitsu Esprimo D556 machines and I can't get it to connect to the server. In the BIOS I have enabled the Network Stack which gives me the PXE IPv4 support. When I try to boot to this it says downloading NBP file then I get a Secure Boot Violation - Invalid signature detected. Check Secure Boot Policy in Setup.

I have tried turning off the Secure Boot Policy and this removes the option to boot to the IPv4 PXE

Can anyone help with this please?

Hello,

First of all below is the infrastructure detail:
1. We have Tectia SSH installed on one of the Windows Server.
2. From Application (On Linux server)  interface Domain user logs in to Windows server via SSH and executes A per script which is located on Netapp filer (CIFS share). Here user logs in using key based authentication rather than with AD credentials.

During execution of the perl script user gets message "Access Denied".

We did below test:
1. When same user logs in to Windows host (via RDS) and executes the script on filer, it gets executed.
2.. From putty when user logs in with AD credentials, perl script gets executed.
3. Now when logged in with same domain user, but this time with key based authentication from putty, he gets access denied message, when tried executing same perl script.

Clueless, why this is happening. Could you please help :-(

Best Regards,
Gurucharan Nayak H

Hi,

I have tried basically all options I found on the net to enable copy/paste from Win 10 host to Ubuntu 16.04 guest.

1. Copy Paste and Drag and drop are enabled in VMWARE Workstation
2. Installed open vm and vmware tools and confirmed service is running. Tried also open vm desktop to no avail.
3. Rebooted multiple times.
4. Closed and opened Vmware workstation player.

What else is left to try?

If i were after a laptop, my question would be answerable in one word: 'Thinkpad'

But what i'm looking for my client is a small netbook with say a 10 inch screen that is light and as powerful as possible that can be picked up cheaply as a used item. I used to be pretty happy with Sony Vaio netbooks with Atom processors, even ones with 1GB of RAM. But i don't think even double that is realistic these days, web pages being as bloated as they are. This would be for general use, with a Debian Linux ( probably Mate) desktop. I'd probably be using ebay.co.uk but am willing to look at new options as well as used. Any good recommendations?
