Lock's questions

I'm having trouble finding where to edit the password of a VPN user that I setup over 5 years ago. I don't know a lot about this stuff and surprised I ever got this working many years ago.

It's a Centos server running OpenVPN - PPTP server whereby the users connect with a simple username and password. The username/password are not the users of the server- I remember they were stored literally in plain text in a file in the form of {username}:{password}.

I can't remember where this file is stored! Any ideas how to find it?

My /etc/openvpn/server.conf file looks like this:

local xx.xx.xx.xx
port 1194
proto udp
dev tun
tun-mtu 1500
tun-mtu-extra 32
mssfix 1450
ca /etc/openvpn/easy-rsa/2.0/keys/ca.crt
cert /etc/openvpn/easy-rsa/2.0/keys/server.crt
key /etc/openvpn/easy-rsa/2.0/keys/server.key
dh /etc/openvpn/easy-rsa/2.0/keys/dh1024.pem
server 10.8.0.0 255.255.255.0
push "route 10.104.17.0 255.255.255.0"
route 192.168.5.0 255.255.255.0
client-config-dir /etc/openvpn/client-configs
ifconfig-pool-persist /etc/openvpn/ipp.txt
keepalive 5 30
comp-lzo
persist-key

We fired up a test SSRS service that hasn't run for a couple of months. It appears that it has decided to send all reports where it has missed the schedule (so any report that didn't send since it was turned on).

We obviously don't want this. What would be a good process for stopping this from happening when starting the SSRS service that hasn't been active for a while? Is there a SQL script around that can remove any future scheduled reports?

I have a problem which I am hoping you experts can really help me find the root cause of. I am getting random page time outs (which manifest as a 500 error) that I cannot find the root cause of.

PHP Version:

IIS Version:

Version 7.5.7600.16385

FastCGI:

C:\Users\lock>%windir%\system32\inetsrv\appcmd list config -section:system.webSe

  <fastCgi>
    <application fullPath="C:\php5\php-cgi.exe" activityTimeout="700">
      <environmentVariables>
      </environmentVariables>
    </application>
  </fastCgi>
</system.webServer>

I have turned on Failed Request Logs and I get the following for random pages:

C:\php5\php-cgi.exe - The FastCGI process exceeded configured activity timeout

Time taken is 700007 msec

Last night, I created 2 files that simply run a very light query on MySQL and ODBC and ran them every minute. Checking this morning, the only file that resulted in a FailedRequest was the ODBC, so I am sure the problem is in connecting to ODBC. I created a new ODBC data source connecting to the same server and driver, but different database, and still get Timeouts, so I don't think it is the database itself. I'm going to try and see if it is the odbc_pconnect or the odbc_exec function that is timing out. I was able to replicate the issue through my own browser (it hung for almost 15 minutes before producing a FailedRequest Log) and at this time, I was able to fire up another browser and run the same page without issue, so I don't think it is anything to do with table locking on the database or what not.

Any help would be greatly appreciated- we really don't know where to go from here!

I have an IIS 7.5 website that I want to allow anyone coming in from the internet to require a password before they can view the site (Basic Authentication), whereas anyone coming from internal network should not need a password.

How would I go about this?

Is it possible to install a 32bit instance of SQL Server and a 64bit instance on the same 64-bit server?

I have ODBC drivers that are 32bit, and need to use these as linked servers in SQL Server, so I need to install the 32bit version.

I have a Hyper-V 2012 server with a 2GB disk.

Currently, there is 50GB free on this disk as the remainder is assigned to a VHDX.

I need to migrate a Windows Server Installation into a new copy of Windows on a new VM. If I create a new VM on the disk that has 50GB left (so a new VHDX with say, 45GB), once I have fully migrated the original VHDX and deleted it, can I expand the size of the VHDX?

Sorry if I explained that badly! Very new to Hyper-V!

Why can't I create a new partition as per below? This is the disk of a physical server running Hyper-V 2012.

Any help appreciated!

I've been requested by RapidSSL to reissue my SSL certificate to 2048 bits. I generated a key, CSR and got the certificate back from RapidSSL.

Now, somehow, I've forgotten what Passphrase I used when generating the Key. Apache is asking for it, telling me "5 tries left". For the moment, I've reverted back to the old certificate.

What are my options here? Can I recreate a new key/CSR and generate a new certificate with RapidSSL? I don't see the option anymore to generate a new certificate. What happens when too many attempts to guess the key are put in?

I have deleted a .avhdx file stupidly due to disk space issues, and lack of knowledge of VM's. Obviously when I try to start to start the virtual machine, it wont start because the file is missing.

Are their any options here to recover or am I royally screwed? How do I run getdataback on a Hyper 2012 install without a GUI?

My old mans 2003 SBS Server is doing weird things.. specifically with Exchange. Inbound emails are trickling through slowly, but outbound emails have stopped working.

Is there a way to track outbound emails to see what is happening with them? We use a smart host which is our ISP.

Thanks

I have an oracle database with 2 users. I have created a table in one of the user accounts, but cannot access the table from the other account ("table or view does not exist"). It doesn't work when I prefix the table name with the username either.

I've also created a public synonym for the new table but am still having the issue.

User A cannot access any objects out of B (even with prefixing), but user B can access objects from user A (has to prefix).

What am I missing?

Thankyou

I am having some troubles with postfix. I am using it currently for SMTP only, and it was working fine. Then it stopped working. The log wasn't showing anything at all so I am unsure if it was a connection issue or not.

The logs are showing this howefver:

Aug 30 16:25:14 westc01-01-01 postfix/anvil[14400]: statistics: max connection rate 1/60s for (submission:203.43.xxx.2xx) at Aug 30 16:21:50
Aug 30 16:25:14 westc01-01-01 postfix/anvil[14400]: statistics: max connection count 1 for (submission:203.43.xxx.2xx) at Aug 30 16:21:50
Aug 30 16:25:14 westc01-01-01 postfix/anvil[14400]: statistics: max cache size 1 at Aug 30 16:21:50

What does this mean? Does this mean that Anvil is limited the amount of email that can be sent through the system? Could this be why email just stopped sending, with it sitting in Outlook? This is a newly configured mail server so i'm sure there are many things wrong at the moment. Any advice appreciated!

I have setup Postfix but am having trouble with the setup.

Whenever I used to send emails to the server, it reject my mails saying 'Relaying Denied', so I changed the following in main.cf:

mynetworks = 0.0.0.0/0
mynetworks_style = subnet

I can now send email and it works, but MX tests say that it is an open relay (obviously unintended).

How can I resolve this? I obviously want anybody to be able to email my domain, but I'm unsure of the configuration.

I know I can change the mynetworks, but then doesn't this restrict who CAN email to the server?

I have setup a new mail server which will eventually replace a current mailserver. Now, without changing the MX records to point to the new server, I will be unable to test this mailserver. Is their a way that I can still test that the mailserver is working? I've created a new domain alias (such as test.domain.com) and that is working fine- just wandering if there is any way through some DNS tricks that can trick an email program into sending the email to a different host (such as my new host) than the current email server?

I am trying to setup iRedMail and am way over my head here. I have installed it, and can send emails internally, but not externally. When I send an email from outside, I get the following return email:

The error that the other server returned was: 550 550 5.7.1    
<[email protected]>... Relaying denied (state 13).

Now I have no idea where to start looking! Any ideas? I have really only just installed iRedMail so I am unsure what else I need to do to get it working. I've pointed my MX records to that server, so that shouldnt be the problem.

Also- if i stop postfix (so nothing is listening on port 25) and send a test email, I get the same reply back. Why would I get the same reply back even if postfix is stopped? I have run tcpdump over 25 and can see the packets coming in/out, so its definitely a configuration issue!

I suppose my question is not really "what is my problem", but more "What configuration needs to be completed on postfix and iRedMail?"

I am having trouble with a newly installed server that we have just migrated to. I am running sendmail and cannot send mail to a specific domain. Mail everywhere else appears to work. Logs say:

DSN: Service unavailable

Weirdly, I get a Message accepted for delivery and then a following entry to say DSN: Service Unavailable.

Why would this be? I do not have it relaying through a smart host. The server that I am sending from does not have a public IP and is purely for sending mail from a PHP application.

Any advice appreciated as Google hasn't been a big help.

I am trying to test whether I can get to a particular port on a remote server (both of which I have access to) through UDP.

Both servers are internet facing. I am using netcat to have a certain port listening.

I then use nmap to check for that port to see if it is open, but it doesn't appear to be.

Iptables is turned off.

Any suggestions why this could be? I am eventually going to setup a VPN tunnel, but because I'm very new to tunnels, I want to make sure I have connectivity on port UDP 1194 before advancing.

How do you know if a site to site VPN tunnel is established in OpenVPN? Apart from pinging the other side, is there a command or something that shows the status of the tunnel?

If I have a RAID array and I switch out the controller to a newer controller, does this destroy the array?

E.g. I have 6 drives as 1 RAID0 array. If I upgrade the controller to a different one, but don't configure anything, should I be able to plug the old controller back in and the array would be unharmed?

Building my first server and have a small question that I'm unsure of! We've purchased an X3650 M3 server, with 2 processors and 8 DIMMS of memory.

Now I am unsure of the memory installation for 2 processors. The server has 2 banks of memory slots, 1 set next to each processor. In the instructions, it has the order in which memory should be installed. The table looks a bit like this:

Microprocessor #     DIMM Slot Install Order
--------------------------------------------------------
        1            3, 6, 9, 2, 5, 8, 2, 4, 7
        2            12, 15, 18, 11, 14, 17, 10, 13, 16

Now, I have 8 DIMMS of memory. Is the table saying "if you have 1 microprocessor, use this the installation order of 3, 6, 9 etc, if you have 2 microprocessors, use the order of "12, 15, 18 etc"...

or is it saying that you separate the memory per processor (so perhaps 4 dimms of memory in each bank).

I hope thats not too confusing to understand!
