Server :: No Server Is Fully Synced With Remote NTP Server
May 13, 2011
I have been working on NTP to find out resolution of my issues unable to find. let me briefly explain here. I have three servers and no server is fully synced with remote NTP server.I don't know why it sync time alternatively with remote NTP server and LOCAL whereas there is not issue in connectivity/reachability of NTP server and NTP clients. Also server 1 reporting kernel time sync disabled 0001.
I get the following error while starting apache httpd
Code: httpd: Could not determine the server's fully qualified domain name, using <Server's-ip-address> for ServerName I googled it and have come across the following solutions, all of them involve changing the ServerName setting in httpd.conf:ServerName localhost ServerName www.example.com:80 ServerName <ip-address-of-server> ServerName <hostname-of-machine/FQDN>
I am setting up httpd to be accessed from over a LAN, so i don't have a .com domain name. I am thinking of going with the first option, it seems to be working...

My desktop is running 'buntu 9.10 and I have recently aquired a couple of half decent servers running Windows server 2003. I have a few windows app's that I use regularly for work that I have had limited success in running with wine or in vm's. I stumbled upon a how to to call apps in a vm to run seamlessly on the host desktop and did some playing and have succeeded in calling app's on my servers from my 'buntu desktop, the command I have set in my launcher for one of them (DIALux)
My question is, can I change the default application/file association in 'buntu with a custom command so I can double click on a file and have it open in one of these remote app's??If I can, what is the correct custom command to be using as using the above doesn't work at all, it just tries to open the file with rdesktop not the remote app.
I've got an uber simple test mail script in php on my awesome new dev machine running Ubuntu:
PHP Code:
Unfortunately, something is preventing mail delivery. I can't tell from this error log whether it's the remote machine rejecting me or whether it's my machine rejecting the self-signed cert on the remote machine:

I'm wondering what I could change in my postfix configuration to remedy this problem.
I tried setting smtp_tls_security_level = may = may but this did not change anything.
The issue is that my CentOS workstation is in a vlan from where the Intranet's DNS servers are unreachable. For browsing the web there is an ISA proxy server, which I presume resolves DNS for my firefox. However, wget, host, ping and aria2c fail to get any sort of DNS resolution since they're being run from command line.I have exported HTTP_PROXY value, which provides me internet access on console, but,only when I connect using IP address. It fails on name resolution.
My question is:May I redirect the DNS queries to my home PC which would be running a DNS server on a non standard port?I was thinking of putting nameserver 127.0.0.1 in /etc/resolv.conf and then put iptables rule to redirect 127.0.0.1:53 UDP to a.public.ip.address:3535 UDP..I don't know if I am shooting blanks or what, I am not very much aware of this kind of setup.My main need is to provide DNS resolution to console apps.I want to utilize my company's idle bandwidth for bulk downloads, so, using proxy, SSH tunneling through my Home PC is out of question.
I am not seeing what i am doing wrong here, but here goes:
From my server I need to run a command for backup on 25 remote servers (through a script). Now I have pushed the public keys for remote ssh connectivity on all of them and it works ( I can push files using rsync without the need to enter passwords on the remote servers), howver, I need to run the following command:
ssh odsadmin@10.139.111.1 'cp -a /var/www/life /var/www/life-v4'
when I run this command, I keep getting asked to enter the password, I even tried putting sudo in front of the cp, but still get the request to enter the password.
I am unable to use ncftp command I have defined all variables used. i have to copy the data to another server FTPS. When i am executing this command it is throwing error
ncftp -u : option unknown
I am copying total script what i am executing in my server. Please some one tell me is there any pistake in using the ncftp command , or tell me some other commands to copy data to remote server
I would like to connect to a separate mysql server, yet I can't find any documentation on how to do this.How would one achieve this? I am running qmail on centos4.
I have just installed CentOS 5. I have set mysql database to access from remote machines. But now the problem is it is not connecting from the local machine now.
I am implementing an automated backup scheme so I created a shell script which first creates SQL dumps for all MySQL databases, then retrieves all websites from the /var/www directory of a remote server. The latter is working as I am using rsync to get the remote files.However, the MySQL dumps being retrieved are the ones from the local server which is not what I want. I want to get the SQL dumps from the remote server as well.I have a tunnel between the local and remote server which I can connect to without using any password (I added the public key to the authorized_hosts), so I tried to add the following code to the script:
ssh user@192.168.x.xxx
I then attempted to retrieve the SQL dumps and exited from the remote server. However this does not work as I still have to enter exit manually in the terminal for the SQL dumps to be retrieved from the remote host. I don't know why this is happening. This is what the script is trying to do:
//connect to remote server ssh user@192.168.x.xxx //retrieve SQL dumps
[code]...
Is there a way to connect to the remote host AND run the script's code on THAT remote host?
I support a small business which runs a headless Ubuntu Server (10.04 32bit) as a file server which is accessed by Windows machines.Although the company has it's own back-up procedure they have decided to back-up some (none sensitive) files online. The have chosen FileFactory (http://www.filefactory.com/) as the host for this. FileFactory allows files to be uploaded to their server by FTP however I do not know how to set this up on the server.
The idea, if it is possible, is to connect to FileFactory through FTP and then synchronise the data using an Rsync command.I normally access the server through Webmin and it has vsFTP installed. I can access the company's server by FTP from inside and outside of the network so I know that vsFTP is working for incomming connections however I cannot work out how to configure it to connect to the FileFactory server.
Im using CentOs on a remote server. I've recently installed phpmyadmin but cant access from [URL] I checked the files and found only 3 folders in /var/lib/phpmyadmin -config / save / upload - all of them empty. Whenever I try intstall phpmyadmin again it just says its already installed and up to day.
I want to remote-desktop into a windows box that happens be hooked up to a linux server.The linux server uses a static IP. I've already enabled remote-desktop on the windows machine, but am wondering what I need to do server-side to make the server's ip forward to the windows machine. I know this can be done with iptables but I'm not sure how to work it.
Allright, I made a simple script that tarballs my SQL databases weekly and saves them to a backup harddrive.If possible, I would like to have the backups uploaded to a remote server for storage. But, I must have the script delete the previous upload for size contraints.I can only use rsync, scp or sftp. Haven't used any of them really before... Here's my basic tarball-backup script:
Code: #/bin/sh # Dates the new tarballs of current builds. DATE=`date +%m_%d_%Y`

i am learning about the ability to utilize the rsyslog ability to be a server for the logging info from other machines. i have did it successfully, and i get logs from other machines through the network, but i don't know where i can set the server for my desire act on these logs that come from the network. i essence the question is: why the server put some logs at /var/log/messages, and others not ?
right i wouldn't ask without searching first but i didn't find a full guide on how to setup an irc server including hosting it on a irc.*.com sub-domain and including things like chanserv
I have installed a linux server in my office to run 16 machines. Its main use will be a internal mail server but will be also running websites.
I have installed Ubuntu 9.10 server x64 and have got apache running.
I am looking for the simplest more robust solution for smtp, pop3 and imap. I have only ever used qmail before and found it a pain to configure and its getting old so I though I should probably try something new. I have not much experience with running pop3 or imap on linux so would love a suggestion on that.
I'm trying to fully automate a Minecraft server, and I decided to use Ubuntu 11.04 on this computer. The computer I'm using for it is an old computer (it's the old family PC, it's about 5 years old (and running amazingly now that I've formatted the hard drive (compared to how it used to run))) so it won't run the Unix environment (or something like that) and runs the Gnome environment instead.
Anyways; the server auto-starts when my computer turns on (my computer also automatically turns on). Now all I need to do is have my computer auto-shutdown at 12:00AM as well as enter the command "stop" into the running terminal. I plan to later add more commands (such as automatically welcoming people to the server when they connect, but that's not important right now and I'll likely be able to figure out if I can get this working).
This is the command I'm using to shutdown the computer:
sudo shutdown -P 24:00
However, it doesn't work. First of all, I need to enter my password, so I need some way to have the shell file enter my password for me whenever the terminal asks for it. Second of all, it just plan doesn't work, even if I enter my password (like, the countdown doesn't appear). As for entering commands into the terminal, the only way I can think of is:echo "stop" But the problem is that doesn't work because it wont enter into the running terminal (and I don't know how to do that).
