Moving Servers, What Happens To Emails
Jun 5, 2007
I'm going to start moving all my resellers from one dedicated server to another.
I'm going to do it like this:
Suspend their account in whm, but instead of it saying account suspended, it will be changed to something such as "Account Transfer in Progress". This will prevent changes to db's, files etc which could be lost during the transfer.
Once all accounts have been transferred I will change nameserver IP's to new server. They can then use their accounts as normal on new server.
What I want to know is:
What will happen to emails that are sent while the accounts are suspended, will they bounce?
how I could transfer the accounts (150-200) with minimal downtime, I would be interested.

I have web site on one shared hosting. Now I want to move to another provider. However on first one I have around 500MB of emails which I would like to move also, because I only use web mail.
I found some instructions that I can copy Qmail's folders and emails and then restore them, but since this is something that providers will charge me for ($80 just for backup), I'm looking for another solution.
I was thinking that since both servers allow IMAP access, I could simply log in in one and another and then copy emails between folders.
- Would this work?
- When I log in with Microsoft Outlook, I only see "Inbox". I don't see "Sent" or other folders which I also have to copy. How to work around this?

I'm looking at moving the hosting of one of our clients to ourselves. (which would be through eukhost).
I've set up brand new websites before, but not existing ones.
If I leave the domain at where ever it is currently registered, I guess I can login to their Cpanel and adjust the DNS to our own servers. Is that best?
But my main question is, what happens with the email?
There might be say 50 email addresses running from this domain.
I don't want anyone to have to go editing settings in their outlook... Is it just the MX record you edit in the Cpanel of the domain, and voila, it all works off the new hosting?
I'm learning more about web hosting, but don't really know anything on the email hosting front!

Im about to move servers as my old one was running so slow, but im worried about losing important emails in the change over. I remember reading something ages ago that said if you change a specific setting on the old server 24 hours before switching then when you switch the DNS will route to the new server quicker.
way, AVOID Stiletto Media web hosting. There support is useless and they have regular downtime, like 8-24 hours a WEEK. The servers are also incredibly slow. Dreamweaver constantly times out when trying to connect!)

I want to move around 20Gb of files from dreamhost hosting account with custom control panel to a cpanel VPS in another datacenter.
Is there anyway of transferring all the files to new host without downloading and uploading to the new host. Coz i have normal DSL and 20 GB downloading and uploading can take years.
There are some forum files CHMOD to specific values if you can transfer them without resetting them in new host also cool.
Can anyone give help? both servers have SSH and FTP
I get to know you can rar them and Wget it from the VPS.
But thats file by file.
Is there a way to move complete directory with wget command?

Long story short, my web host is unreliable and after a down period of 3 days - I want to move my website to a new dedicated server.
Old Server - Fedora Core 6 with Plesk 8.1 (64 bit)
New Server - Cent OS 5 with Plesk 8.0 (Still to confirm version)
My problem is how to transfer all data from one server to the other? The most important item to backup are the emails, and the rest I can do manually. Ideally I would want to backup the entire server in a one, and upload it to the new one but I doubt that will be possible.

how to go about switching mail servers.
mail.domain.com is used as the MX record and is where users point their mail clients for POP/IMAP access. I'm obviously going to be relocating the record to a new IP.
My questions are:
In the interim period, can I have exim 'redirect' POP/IMAP connections to the new IP (for users), and can I have exim relay/forward (not sure on the term in this case) mail received from old DNS caches to the new mailserver IP?

Does anyone have any suggestions on how you would physically move servers from one datacenter to another with minimal downtime?
The IP address is going to change, so the server will go off and then come back online with a new ip.
Just how much downtime is acceptable before customers get annoyed?
When is the best time to do it?
Move them yourself or courier or any other ways?

I am moving a couple clients over to my server tonight, but I wanted to make sure I took steps that they don't miss any e-mail that might be sent. It is my understanding that say the switch happens tonight at midnight. Any e-mails they did not download from the old server will be stuck on there correct? Because they would come in the next morning and hit outlook and download just from the new server?
Is there a set protocol for doing this move with minimal client hic-ups?

I currently have 2 DNS Servers with CPanel-DNSOnly Installed, used with CPanel's DNS Clustering options to store dns entries from CPanel web servers.
I am looking to buy a Windows server(probably with plesk), which i think will not support current CPanel DNSOnly Servers ?
What i need to do is
1. Migrate CPanelDNSOnly(which uses BIND) to TinyDNS on both servers
2. with a simple web-based management of dns entries(to give control to my clients, like DomainDNS.com)
3. and auto updating of DNS Entires from other CPanel and Windows servers, without conflicting same domain records from different servers (which i think can be solved by updating entires by Latest Modified date/time).
I am not an expert, and not really sure if i will be able to setup everything myself. here i need your help, guidence, and links to tutorials and help... From where should I start? What and How should I do? Should I consider hiring a System admin? any sugestions or reference for such admins?

I have a question regarding status pages. Whilst setting up a new website, upgrading forum scripts etc what is the best way to redirect users?
I would like myself and one other person to have access to run the tasks, however I would like to redirect visitors to the website to a standby page whilst we are doing this.
What is the best method? .htaccess? IP based?

We recently moved all our hosting accounts from our servers to new servers with a new host. In the process of this move, after moving all the domains and setting the nameserver ips to the new ips, none of the sites are pulling up. I changed the ip for all nameservers to the ones provided to me by the new host but we cannot figure out why the sites are not pulling up, he says everything on his end is fine? Talking about 100+ clients who have been down for over a day now after changing the nameservers and cannot figure out whats going on. All we did was set the ips on my current nameservers to the new ips below.
Now they are claiming they can bring the sites up, but none of the clients I have talked to can bring them up. Also I cannot bring up any domains or ping them from my home or work.
Example domains that are not working that were moved:
bluetongueskinks.net
pokemongamesnow.com
The 204.16.247.150/~username works fine.
See 204.16.247.150/~pokemon
The accounts transferred over fine in WHM. We were using a dns redirect in WHM on the old server before changing nameservers to make sure it pulled them all up fine.
ips for the nameservers 204.16.247.150 and 204.16.244.150.

I have noticed that a customer's emails are banned by certain RBL/antispam filters even though they are sent using SMTP-Authentication through a non-banned SMTP server.
It seems that its ISP IP is blacklisted..... Is this normal?

I have 2 different servers one with Plesk 11.5. and one new just installed Plesk 12.0, the 12.0 will not send emails out but i get them back to the inbox of the outgoing server. is there a fix for this as i have tried both postfix and qmail to send out emails all with the same result.
It seems that something has changed from version 11.5 to 12.
The plesk configuration is installed on Debian 7.7 OS

My Plesk panel (11.5.30) hosts a number of domains that all use Google Apps for Business to host their emails. No emails are hosted on the panel, and the mail server is turned off. So is the DNS server.
Using the mail() php function to send automatic confirmation emails from a website hosted on the panel, they arrive at any address NOT hosted locally, however they fail to arrive at any address whose website is locally hosted.
My initial research suggested that Plesk was routing locally, hence the problem, however the mailserver has been turned off the for domain/webspace.

I have a lot of questions here so if you can't answer them all I understand. even pointing me somewhere where I could get the answers would be appreciated; hardware sites focusing on server hardware, forums focusing on such, etc.
we plan to have three different types of servers:
- db server (self explanatory. mysql. for forums, mysql driven sites.)
- file server (lots of files around ~2-10MB, consistant 70mbps right now, but we want more room for upgrades. needs a LOT of storage room.)
- web server (lots of php files, but also static things like plain html, images, etc. also includes all misc services for the setup-- dns, etc.)
could I be given a rundown for which hardware each of the three should have? I don't need specifics, even just knowing that more ram is important here while cpu doesn't matter as much, or that the fastest disks available are a must, etc would all be valuable info for me. despite that, I certainly wouldn't mind specific hypothetical hardware configs.
for the database server I'm assuming the more ram the better. not entirely sure about the cpu? also not positive on disks...
for the fileserver, how much ram would be practical or useful? disk io will be an issue I'm because plenty of people will be pulling files at once so the disk needs to read from multiple places. scsi (and even raptors) are not an option as we need 750GB+ of space on a reasonable budget. more ram will take some load of of the disks, but how much is neccessary / reasonable?
for the web server I'm assuming cpu first, then ram, but it'll likely need less ram than the db server?
I'm more lost on the disks than anything. scsi on the fileserver is not an option under any circumstances due to $/GB. for the db & web server I'm willing to pay for scsi if the performance increase really does warrant the extra money, but I'd like to be convinced before shelling it out. if you have benchmarks geared at server hardware when it comes to disks I'd really appreciate it.
also, what's the best way to network these together when colocated? each one with a dual gigabit ethernet port and then the communications go to and from the router?

Since Jan 07, one of our servers has been sending thousands of emails to ne.jp hosts.
Eg from logs:

We're absolutely unable to track or find out who is sending it or how to stop this.
So I'm wondering if it is possible to prevent sendmail from sending to:
lsean.ezweb.ne.jp, OR
docomo.ne.jp, OR
softbank.ne.jp

How would I solve this problem as it's making our server load skyhigh 24/7.
Additional info about system:

I was wondering if it is possible to cluster 2 web servers and 2 mysql servers with only one server working as load balancer.
I am planning to use LVS (ldirectord and heartbeat).
Let's say I have 3 IPs allocated to the load balancing server.
111.222.111.222 (Main IP)
111.222.111.223 (Web Load Balancing IP)
111.222.111.224 (MySQL Load Balancing IP)
If a connection is made to .223 it would pass the request to one of the web nodes.
If a connection is made to .224 it would pass the request to one of the MySQL nodes.
Is it possible to do this?
If not, can I run, for example, nginx on 223 IP address to provide forward proxy? (Then it would not be able to HA but the main point is to load balance so)
Also, what would be the best way to keep the data same on both web servers? This is a web cluster for a very high traffic forum with a lot of uploads every hour so it has to do real time synchronization. I heard that DRDB is only one way and not two way so I'm not going to be able to use this.

I am just colocating servers and managing them myself, and renting services off of them. In the future I would like to start offering dedicated servers as well. I am wondering if many companies do this, or if its more of a general practice to just setup as a reseller? The worst part that comes to mind is thinking of how to do billing for the bandwidth per month. With my setup I would only be offering flat bandwidth packages (like 2TB a month) but even so, I cant think of anyway to automate it so WHMCS knows if they went over, if so, how much, etc.

I've been on shared hosting for nigh on 3 years now. My site suddenly started growing rapidly recently and my shared host now has requested that I move onto a VPS or Dedicated as soon as possible (I would stay with them, but they don't have VPS options sadly)
My site is an image host, a dynamic image host too.
About 80% of my visits are from the US so I have decided, even though I am UK, that I need a US VPS.
I need it to be cheap, like $30 (To start with, while I gain funds) and generally reliable.
Would anyone know where such VPSs are? I would like 300MB or more RAM and about 5-10GB of disk space. My main issue right now is quality of customer service, I don't want to end up with a company that either has poor customer service or puts extreme restrictions on activity.
