Hi,

Another department within my company has configured a Linux Server in a DMZ location. They currently have a bespoke application which is hosted using apache.

They have reported that they are unable to send any email messages to an Exchange 2010 server  when entering any email addresses and clicking send on the frontend of the application. The IP Address of the Linux server has been added to the SMTP open relay on the Exchange 2010 server. From the Linux server I'm able to telnet to the Exchange server using IP Address and port 25. I've also able to send a number of test email messages using Postfix.

I don't know how this bespoke application is constructed or what language it's written in. All I know is that the application has the "Alias" SMTPMAIL" hardcoded into the code. The SMTPMAIL DNS record is an A or CNAME for our Exchange 2010 Server. The Linux server also has the details "IP Address SMTPMAIL SMTPMAIL.internal" entered into the /etc/hosts file. Postfix was configured to use the IP Address of the Exchange 2010 as a relay server https://www.rootusers.com/configure-postfix-to-forward-mail-to-a-central-relay-server/

Am I missing anything else this is working on the UAT Linux Server in the DMZ. This server has the same configuration other than it uses sendmail. We switched to postfix after we are getting unable to resolve dns error messages when trying to send test email messages using sendmail. What am I missing we have checked the logs on the Linux …

So my phone stopped working the other day, it just kept booting up to the apple logo and then rebooting. now I have it in recovery mode (itunes logo appears) and it won't do anything with itunes. I keep getting random errors (originally it was 2001, but the more I mess with it, it get 21, 4015, 2025, really random errors) I feel that this has to do with me being a beta tester and it derped since my phone is the last supported one. So I have a question: since it is completely gone: is there anyway, in other expertise, to downgrade it to an iOS 9 and redo it from there? OR I have alway fantasized putting linux on an iPhone. I've looked up youtube tutorials, and it's all VMWare, or Teamviewer, or VNC. I want to completely wipe it and put a Linux Flavour on it. what ya'll think?

I am asking questions about hostupon shared linux hosting


You're overcomplicating things. Exporting the DB and reimporting it is simply making a copy of the DB and you end up exactly where you started.

You do not need to export or reimport the DB. The DB is already there and ready to go. Just install the scripts, point them to the DB.

The pointing is done by editing the DB settings in the script configuration file. If you do not know the DB user password, you can reset it and use the new one.




how can I
edit db settings in script configuration file

I have database (but forgot password). I can see database because I have access to cpanel and can use phpMyAdmin

how do I reset password??
is this wordpress password or database password?

I am pretty familiar with scripting on LINUX.  However I am not familiar with every command LINUX has.

I need to be able to query the Windows AD and retrieve the following information:
Username, Full Name, UID, Last Change, Minimum password age, maximum password age, warning in days before password expires, is the account disabled, account expiration.

Can this even be done?

Thanks,
John

This is using the Veeam agent for Linux for my CentOS and Redhat machines. I downloaded this agent - veeam-release-el6-1.0-1.x86_64.rpm from Veeam website. The setup is completed successfully on both machines. Initially, a dkms was failed with fail depencies. However, after the new dkms (ver 2.3.x) was downloaded and installed, setup completed without problem for both machines.

After that, I configured the scheduled job. My redhat machine can complete the job successfully. But not CentOS (v6.4), the backup straightway stopped with the error message as attached. Does this has to be related to the file system? What is the main reason why the backup failed in my CentOS system?

Thanks in advance.

Hello

I have tried a number of times to reduce the size of my EBS volume. I keep running into problems.

I am using Centos 7.3.1611 and Plesk (set up through Amazon marketplace)

I have managed to copy all the files over from the old server to the new using the instructions here (https://superuser.com/questions/1123799/how-to-decrease-size-the-ebs-root-volume-of-the-rhel-instance-in-aws) - as well as similar other guides.

The only difference is because I am using xfs instead of ext4 I was unable to do the e2label

When I attach the new volume to the instance as /dev/sda1 it does not load. I cannot connect to it using SSH and websites do not load.

I am at a loss now. I have tried so many times. I made a mistake making my initial EBS volume size way too big and it is costing me quite a bit of money every day.

I am unsure if the problem is because I am formatting my drive is XFS. This was the format of the original drive when I first set up the instance. I have not been able to find a guide that details how to shrink an EBS volume that is formatted in XFS, they are all for ext4.


If any one could provide some assistance that would be much appreciated.

I am porting a legacy f77 FORTRAN application from Tru64 UNIX to LINUX 64 bit OS and compiling with an f90 Intel compiler.   When running the application on the Linux platform, there is no FORTRAN CARRIAGE CONTROL in the output files, so the files are not readable in notepad.   We have a VB program that parses the plot data from the output and exports to excel for plotting.   The VB also complains of "Input past end of file." So I believe the output is missing the EOF for the file as well as the CC objects.

Do I need to suck it up and recode the VB and start opening the file with notepad++ to view?  Or is there a compiling option I can use to embed the CC into the output?  Is there anything else I may have overlooked?

This worked before with the UNIX Tru64 DEC-Alpha platform.

Hi,

I have a two node cluster of RHEL 6.2 with a quorum disk, and resources are IP Address, GFS2 file system (child to IP Address) and http service (child to GFS2).
Following is what i have noticed.

When one node(second) goes down, service group runs normally.
When the first node reboots (second node is still shutdown), the service group does not start. clustat command dose not show the service group. Manual mounting of GFS2 filesystem also freezes.

But when i made the second node up, the service group started normally.

Is it a normal behavior?

Note: I made second node down temporarily to maintain temperature and power consumption.

Thanks

What you need to know to help me with this issue, I am running a Centos Linux Server with Plesk 12.5 Control Panel. I recently installed the Notepad Site Builder Module in my Panel to allow my users to create their own sites for their own domain. After i installed the module every thing seem to work fine, up to the point when i try to publish the site to a domain on my system. The following occurs:

Sitepad module running in Plesk 12.5 :Error Message after publishing attempt

ERROR:  Some FTP errors occured : fsockopen fails No route to host (113)

Try a different website builder and received the following error  below
Website Builders module in Plesk 12.5 :Error Message after publishing attempt

FTP passive mode error
ERROR: FTP passive mode should be enabled on your server for website publication to work.


I am running firewalld as the system firewall and a Router using port forwarding for my open ports. I am not clearly sure what i need to do to resolve this issue for my users. Please help.

Thanks Andre’

After a recent series of upgrades, my Debian linux system is now showing unwanted colors and bold styling.  Previously all terminal output was standard text.  An example is shown below.  (While it is not obvious in this screen capture, parts of the cc error messages are in bold.)

Debian linux Putty session
The terminal emulator being used is Putty.  While I could change all Putty's attributes to disable bold and colors, I'd rather solve this at the linux end.
