A server is a computer program or a machine that waits for requests from other machines or software (clients) and responds to them. This architecture is called the client–server model. The clients may run on the same computer or may connect to the server over a network. The purpose of a server is to share data or hardware and software resources among clients. Typical computing servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers.

After 30+ hours of research and trying different solutions I have found many solutions to each piece of this puzzle but can't quite get them to work together or figure out the best approach so I'm hoping you guys can help.

The goal: Use public IP from a remote server(Ubuntu) as a browser proxy. The kicker is that the server should pass all traffic through to a local machine which has a 4g modem internet connection to use its internet connection. We need to be able to assign fixed IP addresses/IP port combinations to these local modem/s to be used as undetectable browser proxies to make it appear that the browser client is logged in using the mobile internet connection.

I have seen multiple solutions to each part of this including the use of ssh tunnels, dynamic port forwarding/socks, remote port forwarding, squid proxy server/other proxy server software, iptables configs etc..

I have found this solution that I can get traffic to travel from anywhere to my local machine:

//1st terminal establishes connection/tunnel ssh -nN -R 8888:localhost:8889 -i "connection.pem" ubuntu@e-xx-xx-xx-xx.remote-server.com

//2nd terminal listens on port 8889 netcat -l -p 8889 //this command works and prints abc on the local machine echo "abc" | nc -v xx.xx.xx.xx(remote server ip) 8888

I have also successfully installed a squid proxy server in a docker container and used the following command to open socks connection with reverse forwarded port.

Please have a look at the image attached:

here is how my flow is
 1. Database server
 2. Application server and application server can establish connection with database server) (here the crystal report will run fine)
 3. Local system (and client will establish connection with the application server) (here the report is not working)
Image01as i'm not able to connect to database server directly, how i will open crystal report from client system.

I want to find a way to get sound on my VPS at Vultr VPS I found a VSC aka Virtual Sound Card It was a little tricky to get working for some reason it would not install? It just did nothing after double clicking the EXE! I came up with the idea to convert it to MSI. I used emco Software MSI Package Builder and it installed the EXE for me. I figured I would install the MSI but emco installed it for me! So now I have a VSC now I want to connect it to my C-Media PCI Sound Card in my home desktop. I am going to use The NAS Project aka The Network Audio System and Port-Endpoint the C-Media PCI Sound Card and VSC together with VAC from Eugene Muzychenko Software aka Virtual Audio Cables. Then my VPS will have sound coming from my home computer speakers but they will be playing what the VPS is hearing while I am on the console. Is there anybody who can step me through this procedure I am not really talented at networks and there is a lot of protocol that I dont know. Plus really nobody does this kind of thing.

I recently got an older server. 6gb RAM, 1x2tb RAID array. 4 core CPU. Literally an old file server.

I upgraded their server and took this one.

It originally came with Server 2008, but I was unable to recover the key (they wiped the drives and it didn't have a sticker on it.

I was wondering of a linux OS with a web-based GUI. I have used Webmin in the past, and I like it, but it doesn't seem to be updated very often.

I want to know if there are any similar to you Webmin that you like to use. I don't really want to hang out in my office staring at a screen and I ain't great with terminal commands (through SSH). I like the module options like in Webmin. I have also tried Cockpit project, but it doesn't have much on it. And ClearOS is not that easy to use when setting up samba share. Amahi, I have the same issues.

What are your recommendations??

okay also the operating system of the rescue disk is Debian and that of Linux server is CentOS 5..I am very new to this so please forgive my
haphazard formulation of the problem.We were supposed to check and then recover the datasystem of a supposedly corrupted linux
server using the fsck command. Now here the problem comes we first ran the fsck commands and the answer was that those commands cannot
be run as the disks were in use. So we started unmounting the disks one by one till there was none left and then we again ran
fsck commands this time..But the command failed to do anything. Various attempts to remount the different drives also failed.
So our questions are three fold

1) How do we get all the drives back in original configuration
2) How do we properly run fsck commands to check and rebuild the corrupted drives
3) if the system logged out of rescue mode and is restarted in normal mode at this moment will we lose all the data that is stored in that server




first time running fsck, df, fdisk commands

rescue:~# fsck -A
fsck from util-linux 2.25.2

I have an old version of Business Objects Crystal Report Server Software that we are trying to reinstate for Project Management.  My owners don't want to spend the money for the latest/greatest in similar software.

I have everything running except for the CMC.  As soon as I start it, it falls on its' face and goes right back to a stopped state.  When I go to check the connection for the CMC I get the following pop up:  CMC Generated Error
The event logs list the following, similar, error:  Eventvwr Error
The environment is a virtual Windows Server 2012 R2 with a SQL Server 2016.

I have deleted and added the DSN numerous times with different drivers to no avail. (In the 32 Bit ODBC)

It should be noted that when I set up the DSN, and the connection in the CMC, it successfully connects to the database.  The error only happens when I go back to the connections tab in the CMC.  

The only possible issue I thought about was that this is a 64 bit virtual and the software is 32.  However, I have never had an issue with this in the past on physical servers. (64 vs the CS 32 software)

Is there a way to see what the CMC is submitting for the connection string?

Does anyone use Essentials anymore and if so why? What are the benefits for a small company of 10 or less people.

I've been using Server 2016 Standard more often for small businesses with 1VM as the PDC and the 2nd as Exchange. Have a client already on Office 365 thinking Essentials is the way to go. A concern is they may need an additional server, am I correct Essentials doesn't come with any VM's options and we would have to purchase another server?

Client also likes the remote access they had prior in SBS, this is an add on, correct?

Finally, am I correct and the 25 user CAL's are included in Essentials?

Recently, our W2012R2 RDS server has started giving users problems logging in. The message is:
The number of connections to this computer is limited and all connections are in use right now. Try connecting later or contact your system administrator.

I'm having a hard time finding any helpful information on how to resolve this issue other than on desktop versions of Windows.

In a bid to get around this issue, I've opened more ports (HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp 339x), and this has given some temporary reprieve.

It seems to me that the issue is pervasive. By that I mean that the message does not disappear even if existing users log off from their RDS sessions.

This RDS server has been working fine for years, and now, suddenly, this happens.

SCO Unix 5.05 Network Issue

So let me start by saying Im not familiar with Uniex. I had to reset the router here at my work yesterday and redo the network. This in turn lost the ip address settings in the router and now our Unix server is not connecting with the router or sending emails in visifax. I tried changing the static ip that was set up from 192.168.1.254 to 192.168.1.144 as the new router issues 192.168.1.100 through 192.168.1.149 ip address. I used netconfig for this and it took the change but to no avail. Now im dead in the water. I dont know what to check or what to change to allow for it to make a proper connection to our router. The pc's here can connect to the server through the serial direct connections and also access the router fine through the network. Any help or advice would be APPRECIATED!!!

my concept
I have a homebrew "server" setup I am trying to condense into a few. I have been replacing hard disks for SSDs and now I have a lot of HDDs laying around, I do software RAID 1 with them in PCs and run Ubuntu server, but I have an idea on how I want to set it up cleanly, however, I do not know what to do, where to search for tutorials.

I attached what I want to do in a picture, if anyone could point me in the right direction, that'd be great.

Again, this is for home use, I just want to learn about servers in general and the software.

Apparently, the image didn't upload, so here goes a second try

Hello All,

I have integrated Kamailio 4.4 with asterisk 13 LTS and I think its been properly integrated. It also shows me the registered users but when i call from 101 to 102 it gives me the below error

[May  7 12:43:14] NOTICE[19838][C-00000000]: chan_sip.c:25545 handle_request_invite: Call from '101' (192.168.56.103:5060) to extension '102' rejected because extension not found in context 'public'.

I have followed the below for installation and configuration.

http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb

The user database is fetching from remote host in which kamailio has been installed. Users are showing in asterisk node as well

asterisk*CLI> sip show users
Username                   Secret           Accountcode      Def.Context      ACL  Forcerport
101                                                          public           No   No
102                                                          public           No   No

So how can i debug this or is there any clue that what might be wrong. Please find below  the extension.conf details as well.

exten => _1XX,1,Dial(SIP/${EXTEN})
exten => _1XX,n,Voicemail(${EXTEN},u)
exten => _1XX,n,Hangup
exten => _1XX,101,Voicemail(${EXTEN},b)
exten => _1XX,102,Hangup

Thanks and looking forward for some clues from this community

Microsoft Dynamics AX slow
People at our company use Remote Desktop to access their Dynamics AX clients.
The AX Clients connects to Dynamics Application Object Severs (AOS), which in turn talk to the AX Database server. Very normal setup.

Problem:
A user will open (for example)
'Company/Sales and marketing/Common/Sales orders/All sales orders'  
or  
'Company/Service/Common/Service call/All service calls'  
(each have several thousand records)
It could take a minute or more for the record page to open.
However, if the user uses a client directly on the AOS server. (RD to the AOS, use the client on the AOS)  The page opens in >5 seconds.

Sounds like the RDS machines are the problem. RD Servers are running great. CPUs are good, Memory good, disks good, network traffic good. What else???
Problem can be repeated with just one user on the system. (normally have 200 users connected)

I am trying to create a virtual domain in wampserver, when i try to create one in the "Add a virtualHost" panel i get the message "c:/users/edkna/desktop/allsites/site1 does not exist or is not a directory", even though there is a directory there.
I tried creating a directory in multiple places on my computer (which i have full admin rights to) I am carefull to correctly copy and past the path to the directory and paste it into the "complete absolute path of the virtualhost" field but I get this error message every time. (see the attached screen capture errorMessage.JPG)

Also another issue that is probably related to the above issue, when I tried to add a second directory in  C:\wamp\www  for a another Wordpress site, I get the following error messages:
( ! ) Warning: Unknown: failed to open stream: No such file or directory in Unknown on line 0
( ! ) Fatal error: Unknown: Failed opening required 'C:/wamp/www/site2/index.php' (include_path='.;C:\php\pear') in Unknown on line 0 (see the attached screen capture anothrErrorMessage.JPG)

Can you tell me how to fix this problem?

Hi Dave,
 you said it could be a permissions issue.  Properties/Security show I have full control.  This is also my personal computer which I have all privileges to. are you referring to some other permissions that I am not thinking of? I was able to create virtual domains six months ago, so I don't know of any thing that is different on my computer now.

I need to setup a new server for a veterinary hospital wth 10 users on Windows 10 workstations. They currently use a workgroup with a workstation running server 2018 for shared data and printers. I want to setup an AD domain because managing user permissions and workstation setup and configuration is getting too time consuming in the workgroup environment. Their database size and shared file storage needs are very low so we don't need enterprise level power. I just want the minimal server hardware and os necessary for AD management, some remote access, group policy changes and to standardize workstation UI and software configuration, plus physical space for server hardware is very limited. Extra capacity for future growth is not necessary because they are at the maximum physical size that is possible for their location.

Thank you

Cloud based application having issues with ldaps bind to our Domain Controller in DMZ.
The application vendor is seeing the follwoing log entries on their side:
           [7:Public User][1024:application notice][R] (:) - Unable to bind to the LDAP server.

Based on this they have taken a wireshark capture and seen the following sequence of packets:-
Source -> destination (DC)   TCP    49662->636 [ACK] Seq=805 Ack=12910
Source -> destination (DC)   TLSv1  Application data
Source -> destination (DC)   TLSv1  Encrypted Alert
Source -> destination (DC)   TCP    49662->636 [FIN, ACK] Seq=927 Ack=12910
destination (DC) -> Source   TCP    636->49662 [ACK] Seq=12910 Ack=928
destination (DC) -> Source   TCP    636->49662 [RST,ACK] Seq=12910 Ack=928

They are saying that the reason packet analyser highlights the [RST, ACT] packets in red is because after the connection closure by Cloud Application server (source) [FIN, ACK] , server is expecting a final [FIN, ACK] from Domain Controller  (destination) but [RST, ACK] arrives instead. And thus they believe that it could be a issue with the Domain Controller.

Is this claim correct?
What can we do to troubleshoot this further?

I have been trying to setup a Hyper-V proof of concept system for quite some time. I am using a free Microsoft eBook titled "Deploying Hyper-V with Software Defined Storage & Networking" by Mitch Tulloch. There are probably other ways to do this, maybe better ways but this is the way I chose to do it. I have attached the eBook to this question for reference.

I am having an issue with configuring network virtualization. The steps used have you adding a couple of Gateway VMs through downloadable service templates from Microsoft. You deploy then configure these gateway VMs, create a configure a VM network and then deploy a couple of VMs on the compute host group to prove connectivity. Except the connectivity is not there. Neither VM can "see" outside its subnet as if the gateway is not doing its job.

I think the issue lies in the part where I am supposed to "configure your physical switch infrastructure to be able to route traffic into and out of this VM network and the respective virtual subnets" I am really not sure what this means.

I know this is really high-level but please ask any questions for the detail that matters to you.

Hi

I've been tasked to setup a Powerchute network shutdown for our vmware environment.

Does anybody have experiences setting up PowerChute network shutdown for vmware esxi hosts in HA cluster environment WITHOUT attaching to vcenter?
Is it possible?

We have three esxi hosts in HA configured and these are managed vcenter which is located on different LAN.
According to official documentaion, for HA environment, connecting to vcenter is recommended, but for our case, vcenter manages hundreds other esxi hosts in other countries, so I'm nervous to connect to vcenter.
http://www.apc.com/salestools/PMAR-9DNLQK/PMAR-9DNLQK_R3_EN.pdf

We just need basic function that power chute provides such as proper shutdown of VMs in order.

Can someone advise how I should setup?

Thank you for your any help
