We have a requirement to configure multiple email gateways, for mail accounts configured on linux server. the application will trigger mails (bulk mails) and we would like to configure multiple email gateway to be used.
we decided to do it this way.
In dns we would create MX records like
yourdomain.com. 3600 IN MX 20 realmailserver1.yourdomain.com.
yourdomain.com. 3600 IN MX 20 realmailserver2.yourdomain.com.
where realmailserver1.yourdomain.com. and realmailserver2.yourdomain.com. will be our email gateway.
and internally on our linux server (from which mail is sent) if i specify multiple smart hosts like
I have setup CentOS 5.2 with Nagios to monitor my network and have that configuration almost done. I have also setup Sendmail to forward all mail (really only Nagios notifications) out to my Exchange server using define('SMART_HOST', 'exchange.domain') in the sendmail configuration file and it seems to be working correctly.is there a way to configure Sendmail to forward all mail out through my Exchange server as it is now but send mail out to the internet itself if the exchange server is unavailable, somewhat like a failover configuration.
I have 16 linux servers that use /etc/hosts files to see and talk with each other. I'm adding servers to this pool of servers. It is required to do host resolution via the /etc/hosts files. DNS or NIS are not alternatives. Aside from manually editing each of the 16+ /etc/hosts files every time I add a server or editing one /etc/hosts file on one server then scp'ing it to all the other servers, is there anyway to edit the /etc/hosts on one server and "push" it onto the other servers that need the new /etc/hosts file?
Everywhere I've looked on the Net, there hasn't been any suggestion except for the options I mention here.
I have set up a SSL site for my default Apache server. But I want to set up multiple SSL sites for multiple IP based as well as Name based Virtual hosts. Is there a way where in I can include definitions for SSL certificates and keys within the Virtual Host directive in the httpd.conf, so that I can specify separate key and cert file for every Virtual Host.
I'm trying to pass multiple dpmains thru one ubuntu server to various hosts on my local network.
[url] should be sent to the /var/www folder on the local host.
[url] should be forwarded to an IIS box on my local network (owa.nunya.local)
[url] should be sent to another ubunto box on my local network (smtp.biznet.net)
I have tried placing VirtualHost entries in /etc/apache2/sites-available/default and [url]and [url] both work but [url] gets forwarded to the c:inetpub folder on the IIS box.
is there any HOWTO for configuring Webmin Postfix server with multiple postfix virtual hosts? Seems to be a tough challenge to set it up without any easy manual..
I've looked high and low but I haven't been able to find any example of what I'm currently experiencing with my hard disks.First off, I'm running CentOS as a Samba file server, on a Soltek SL-K8TPro-939 and AMD 64 3200+ (all the rage of five years ago). Here's my disk setup
Ok, so I get a notification in my system mail yesterday: The following warning/error was logged by the smartd daemon:
Device: /dev/sda, unable to open device
For details see host's SYSLOG (default: /var/log/messages).You can also use the smartctl utility for further investigation.No additional email messages about this problem will be sent.
i have a commercial ISP connection with 5 IP addresses available and i want the following configuration note when i say domain group i am refering to a group of top level domains (not subdomains) owned by the same entity (company) with their A records pointed at the same public IP for a single server
How do I configure samba such that AD authentication still works when a DC is down? Do I need multiple kdc, admin_server, and kpasswd_server entries in krb5.conf?
As a part of migration I am proposing different scenarios to my organization. One which is asked to prepare is to configure multiple mail servers to handle incoming and outgoing mails. Say I have -[URL], I need to have accept mails from [URL] and send mail from [URL].
I want to create a script to insert the fstab and hostname in a textfile of multiple servers on the network without a password. The servers are situated in a text file. So i want to read the text file line by line and write the output into another textfile.
I just downloaded the DenyHosts2.6python2.5.rpm for deny.hosts from sourceforge and would like to set it up. I normally use fish://, smb:// and ftp:// on the boxes on my lan. I already have files called hosts.allow and hosts.deny in the /etc folder. Will the rpm configure hosts.deny when first run?
I am trying to configure Apache to handle virtual hosts. For this I un-commented the line in httpd.conf that say
Include /etc/httpd/extra/httpd-vhosts.conf Then I included the following in httpd-vhosts.conf: <VirtualHost *:80> <Directory /var/www/git.localhost/gitorious/public> Options FollowSymLinks AllowOverride None Order allow, deny Allow from All .....
What is the best way to go about setting up multiple virtual hosts on the same box, one using http and one using https/ssl? I'd like to serve them from the same ip address if possible; I know it's possible in apache 1.3.
I am somewhat familiar with SGE (Sun Grid Engine, now Oracle Grid Engine) commands but am having a problem when running parallel jobs.
Present Machine configuration: machine I - 12 cpus machine II - 12 cpus machine III - 12 cpus .... so on ... One_machine - 16 cpus
(I have all machine of 12 cpus and 1 machine having 16 cpus)
I want to schedule jobs on these machine such that if I ask for 12 cpus - my jobs should execute on any of the machines which has all 12 free cpus (eg machine I or machine II) in this case.
Eg. suppose I ask for 24 cpus
Option I : 12@machine1 12@machine2 ----- I need this
Options II : 10@machin1 10@machine2 4@machine3 ---- I don't need such a distribution
Hence, Option I is ideal here. Also, when running 12 jobs on machine1 (say) - even if all 12 cpus are not being used at some instance of time, none of the 12 cpus should be freed. In short, until my run finishes, all blocked cpus should remain blocked.
If you may understand, the purpose here is to run some performance tests.
I am trying to configure dhcpd to provide two different pools of IPs- one for dynamically named hosts specific to MAC addresses, and another for everyone else.So, a machine with X MAC address connects, gets an IP from e pool, and the server updates DNS with the address under a specific hostname.For the other pool, it just assigns the IP, no DNS updates.The "class" function doesn't appear to allow anything but pattern matching, and I can't find anything that specifies what "allow" and "deny" options therere for the pool command.Here's my config so far - will this do what I want?
I have a server that host's several sites, recently I had to create a new server because the old one isn't good enough for me. Ive installed apache2 on the new server and moved all the files from one server to the other. I'm making tests in my local lan so I've edited my computer's hosts file to point to the name of each site to the local ip of the new server:
I'm having problems configuring my virtual hosts file properly The site [URL]... opens on http and https The site 10.0.1.3/myapp/ works I am trying to redirect all traffic from [URL].... to [URL].... while maintaining access to [URL]....
I have some problem in apache2 configuration. I have two websites on same IP on LAN.i.e. 192.168.1.5
[Code]...
What should I check in a few blogs I checked they said to mention in [URL]...But in this case what should I put I have two different websites or what other thing I have missed? I do not have access to DNS so that on LAN I can point site1.abc.com and abc.com to same IP 192.168.1.5 which to me seems could resolve the issue.
Two exchange servers internally. One is setup for example.com (192.168.1.10) and the other is setup for example2.com (192.168.1.20) Both are behind a single public IP.
I want to use postfix to sit in front of the two exchange servers. Postfix will accept mail for both domains and relay to the appropriate server. I have postfix installed with only defaults at this point.
I'm trying to setup sendmail to use my gamil account as a mail relay but with no success. I followed these guides: [URL]and many others.my machine is a centos 5.5 vm running under opensuse host. ( I hope that its not just a virtualbox problem..)
I ended up with this setup: /etc/mail/auth/client-info: AuthInfo:smtp.gmail.com �U:root� �I:xxxxxx� �P:xxxxxx� "M:PLAIN LOGIN" AuthInfo:smtp.gmail.com:587 �U:root� �I:xxxxxx� �P:xxxxxx� "M:PLAIN LOGIN"
Can I use apcupsd to monitor my smart-ups 2200 without it being connected to a server? I have set the TCP info on the APC and can telnet into it, but I'm kinda confused by what I've been reading in the apcupsd documentation.
If someone can tell me about there experience doing this and best practice that would be awesome.
I have a CentOS 5 box that is a web server. When it generates emails, all emails should go out through our Exchange mail server.I believe our Exchange server requires NTLM authentication:
Trying to install RHEL5-AS 64bit onto HP DL320 G6, with RAID being a mirrored array on the Smart Array B110i SATA controller. The RAID is configured in the BIOS and seems fine.
When I install RedHat, I have to use 'linux dd' to use the HP provided driver (http://h20000.www2.hp.com/bizsupport...5&mode=4&idx=0) and that works fine during the installer, the GUI during the install sees the RAID just fine, it sees one volume, calling it the HP Volume. However, when the system boots after the install, the RAID is gone, and it's now seeing two drives, /sda and /sdb:
I'm trying to use ssh-keyscan to get some known_host file population going on, but I have a ton of hosts I want to scan, all with multiple aliases in /etc/hosts. Is there a way to use my current /etc/hosts file to do an ssh-keyscan instead of making a special list of hosts that (from what I've read) ssh-keyscan needs?
Well, as many proxy applications, GNOME Network Proxy Preferences only allow to ignore hosts. What I want to do is exactly the opposite. I only want to use the proxy for few sites. Is it possible to define only the allowed hosts in any way?
PS: I know FoxyProxy add-on for Firefox does this, but 1)I don't use Firefox and 2)I want the proxy settings system wide not only for browser.
I need to set up a named server for a class room with 10 imaginary hosts the sub domain managed by this name server is s123456.eca.edu.au where 123456 is to be replaced by your student id. The named server will forward unresolved queries to the dns server.
