How would I go about using sendmail with my server's secondary IP address?
It would seem that sendmail automatically sends with the primary
I'm wondering if anyone else has experience with this, or if it's something easy that I'm overlooking.
I am on a VPS service (CentOS Linux) and I want my php mail function emails to send from a specified address. I've already manipulated the headers, so the emails do appear to come from the specified addres, but on mobile devices it comes up as nobody@server1.mydomain.com format. I would like this to read something like no-reply@mydomain.com
know which configuration files can change this default address?
Is there any cheap / stable VPS vendor in UK likes cheapvps.co.uk? I just need a minimum VPS (128MB RAM?) for secondary DNS.
View 4 Replies View RelatedI signed up with cheapvps.co.uk a month ago, and I'm very happy with them . Now I'm looking for a very small VPS to host a secondary DNS server, and maybe a backup MX server.
It's just for personal use.
I think 5GB disk space would be enough, and I would like not to spend more than $10 USD/month. Do you know any VPS that suits my needs?
My customer has an external facing Apache server that is acting as a reverse proxy to two internal applications. They have:
- external addresses for each app which resolve to different ip addresses, so app1.their_domain.com and app2.their_domain.com resolve to 77.3.170.10 and 77.3.170.11 respectively.
- the Apache server has two network interfaces with ip addresses 192.168.10.10 and 192.168.10.11
- the external ip addresses resolve to the above internal addresses
- the firewall between the Apache server and the internal app servers is configured to allow traffic from 192.168.10.10 to reach app_server1, and traffic from 192.168.10.11 to reach app_server2, both using port 7777.
I have configured a virtual host in httpd.conf for each ip, i.e.
Code:
<VirtualHost 192.168.10.10:80>
...
ProxyPass /app http://app_server1:7777/app
ProxyPassReverse /app http://app_server1:7777/app
RewriteRule ^/$ /app/app1 [R,L]
...
<VirtualHost>
and
Code:
<VirtualHost 192.168.10.11:80>
...
ProxyPass /app http://app_server2:7777/app
ProxyPassReverse /app http://app_server2:7777/app
RewriteRule ^/$ /app/app2 [R,L]
...
<VirtualHost>
This works fine in that the external address are being routed to the correct application, however the firewall is blocking requests to the second app as it appears the requests are coming from the Apache servers 'primary' ip address 192.168.10.10 instead of 192.168.10.11.
Is it possible to send requests using the ip address from the relevant VirtualHost?

We need a secondary DNS for our cPanel server, as we want to have separate nameservers. What is the cheapest vps anyone knows that is hosted outside of Bluesquare House (UK). Global location isn't important.

I have 2 VPS's one running cPanel/WHM with about 15 low traffic sites on it. The other is a very slow spec VPS, hopefully just for DNS services.
I only have 1 domain server running currently, this is on the same server as the all the websites, what I want is a secondary DNS mirroring that of the DNS on my cPanel VPS, automaitically....
I was thinking of writting a little script to scp all the .db files in /var/named/ to my secondary server, then login to the secondary server and restart BIND?
What happens if your primary nameserver goes down? Meaning that it goes completely off the net, not even denying dns requests but completely ignoring them.
I'd guess that resolvers would query the secondary NS after a specified timeout, but what is that timeout set to? Does it differ from ISP to ISP? How much of a slowdown are we looking at for end users?
would it be possible to have my main box running apache, a second box for dns/other and an offsite secondary dns such as DNS1.PUBLIC-DNS.NET?
Is it possible to authenticate the primary and offsite secondary nameserver so the zone is transferred to the secondary? Would i need to pay for a special service, or do free ones exist? Are there any security implications with zone files being transferred out over the public internet, would a vpn need to be configured or can the process be encrypted via the transfer procedure?
Finally, how would this affect the way the entire virtual hosting works? I know when the nameserver on the host machine serves resolves a name request for a computer trying to browse the site in question, but when the actual http request goes to the web server does it incldue the domain it is looking at also?
I just ran into something about Secondary DNS services.
What exactly is that?
Is that where if my primary name server goes down, a secondary name server kicks in and resolves all my donmains to another server somewhere?
I've been thinking about getting setup with some kind of fail safe setup in case my primary name server goes down.
Would Secondary DNS services take care of that?
If so, anybody know where I can find a reliable, affordable secondary DNS service?
I am using virtuozzo firewall to secure access.
I enter 58.27.175.211/255.255.255.0 for Source Address and Netmask for port 22.
But still I can connect using 58.181.103.217 or 58.27.151.120.
Second is it possible to enter two different ip address in source address?
I got 4 IP from server.lu
A friend install windows 2008 on top of the vmware.
Then I noticed that the connection is not very right.
So I go to network connection in the hope of changing the DNS.
I just right click the connection and found out that I lost my connection to the server.
Restarting the server allow me to ssh and ping the main IP but none of the secondary IPs work.
The problem is that my hd is failed. Hoster setup new server, also installed the secondary drive but not mounted. So need advice how can i get my data off it?
View 3 Replies View RelatedI have the following three servers, which I'll call A, B, and C:
Server A - Web hosting server that uses cPanel on CentOS.
Server B - Free subdomain service (similar to afraid.org but on a much smaller scale), using PowerDNS with a MySQL database backend, on Debian.
Server C - Backup DNS server for the cPanel web hosting server, using the free cPanel "DNS Only" on CentOS.
Originally I had just A and B set up (they're two separate VPSes on the one dedicated server, I own the dedi and some friends and I have VPSes on it). Now I've got a VPS at a different data centre, and am using that for C.
To have a secondary DNS server for server B, I believe I can use MySQL replication to replicate the PowerDNS database to another server, then have a PowerDNS install on that server. My question is, is it possible to have server C as a backup DNS server for both server A (cPanel server) and server B (PowerDNS server)? ie. is there a way to check both PowerDNS and the cPanel BIND9 for domains (have them on different ports, and make one query the other if the lookup fails, perhaps)? Or perhaps use both the MySQL backend and the bind backend simultaneously in PowerDNS, and replace bind with PowerDNS (although I guess cPanel wouldn't like this)?
i have just bought a dedicated server with 2 ips.
i already put type master in named.conf along with a zone file having 2 nameservers pointing to A records
ns1 IN A 1.3.5.7
ns2 IN A 2.4.6.8
how do i setup ns2 (secondary nameserver)? how do i know it is running?
I have two nameservers, each running physically on a different server on different networks. Now I've noticed that whenever the primary NS goes down, clients requesting authoritative NS record lookups refuse to connect to the secondary NS, which I know is certainly up and running. The secondary NS has its own zone files and when you specifically request that server to resolve NS requests, it does the work. But generic NS lookups without specifying the server appears to fail when the primary server is down.
Does anyone know what might be happening here? I know that the domain registrar has both nameservers recorded for the domains I'm trying to resolve, but what is the point of a secondary NS, when it isn't contacted when the primary nameserver is down?
My sites all respond very slow (VPS) at the initial loading, that's why I try to check all dns settings.
My current resolv.conf
nameserver 64.235.32.203
that is the ns of my hosting provider.
Would I have an advantage if I add another and if so can I simply add my own nameservers?
I am developing a site for a new company that will run under a medical engineering firm. I'm currently the only employee and am setting up websites and graphics for the company, but working out of the same office as everyone else. We currently have a VPS through iPower to host our site on, and everything is dandy. However we only own one IP address on the VPS, and I want to be in charge of my secondary nameserver, as I will also eventually use it as a secondary MX server. I have never done this before so I have a few questions about it. My previous experience has all been graphic design and web design, not much on the hosting side of things.
1.Is it possible to run a server on a XP desktop just using Apache or similar software (and a dynamic DNS service)?
2. Would it be possible to run this through the company LAN and router to make it accessible via the web without any serious tinkering on their network? (it has to stay up, and I have no idea what kind of routers or firewalls they are using currently). Basically given the standard setup how hard is it to open up the ports on the router(s)? I've done this only on a home router before, so I assume it can't be much different.
3. How do you go about doing it?
I've recently got a server with DA panel and a secondary SCSI 15K to put on mysql which I believe should improve the preformance.

We currently have gps devices which report x,y coords. The devices currently report to a fully qualified name: servername.mydomain.com. And only one fully qualified name.
We would like to have redudancy, so if the main server goes down, then the secondary takes over. I assume this is accomblished via DNS.
So out first task is to create name servers at our domain registar and have them register them, for example:
ns1.mydomain.com -> FIRSTSERVERIP
ns2.mydomain.com -> SECONDSERVERIP
Then on the both servers we setup DNS to accept the a record of servename.mydomain.com points to? This is where I get confused. Does the firstserver DNS say point to itself, and the second DNS server point to itself?
in setting up Primary & secondary MS DNS server for MS WIn 2003 server,
View 5 Replies View RelatedI have 2 servers 1 US and 1 UK.
What I wanna do is synchronize both of them using rsync. Once they've got synchronized, the UK will be the primary server and US will be secondary, in case the UK goes down.
my questions are
1. Is it possible that when the UK goes down, the A records for domain.com automatically switches to the US server so it can take over while UK is down.
ie. UK ip 112.113.114.1
US ip 222.111.444.5
domain.com A records = UK ip when up... but when UK is down, A records automatically changes to US ip.
2. And when the UK server goes up again, whatever changes made to US server will be pushed to UK. May it be files, accounts or e-mails.
I.E.
UK and US are synchronized every 30mins. UK and US both have e-mails 1-10.
Just before the sync time, UK server received an e-mail 11-15 then goes down. So the US Server will take over but do not have 11-15 mails, since it was received before sync time. During the UK downtime, US server received e-mails 16-20.
When the UK server goes up, will it be possible to sync both servers that both of them will have the e-mails 1-20?
I hope you get my point...
If these are not feasible, what can you advice as an alternative solution. All I want is to avoid downtimes, especially with mails as the business relies on this.
I have tried the cPanel tool to mount, format, etc. My drive however, it has made my server crash after reboots.
I have to enter single user and remove the lines added to fstab so it will boot.
I tried using the tool again and it failed yet again, can I do it manually, and if so how.
I will have to redo the entire partition, so how do I erase everything first?
