I currently have a server with CentOS 4x and cPanel with approximatley 100 active sites on.
I would like to change the hostname on this box, is this possible without causing any disruption to services on this machine?
Would I be correct in thinking its as simple as modifying /etc/hosts(Or doing it in cPanel) and then reactivating the cPanel License?
I am with a server, I alter the hostname for the command:
root@servidor [~]# hostname newhostname.domain.com
But when I give the command below, it continues the same hostname.
root@servidor [~]# host IP_SERVER
186.18.232.72.in-addr.arpa domain name pointer actualhostname.domain.com
I already altered WHM and /etc/hosts, but anything.
I have one VPS with CentOs and WHm .
No I want to change the hostname for he VPS. So in how many server's configuration files I have to make the changes?
I have a few vps on different providers and I was shoring up my hostnames to make them more cohesive for the different servers.
I placed a request with a well-known, premium vps provider this morning at 9am EDT and am still awaiting them to complete the host name change. They came back immediately and said an admin would have to handle and then noting for hours. At approx 2p EDT, I asked for an update and I received a response at nearly 4pm EDT saying they were still waiting for their admin to get back.
Keep in mind this is a fully-managed, not cheap, vps with a very good rep here on wht.
Am I expecting too much?
I'd change it myself, but I'm unable to do so with virtuozzo.
Now with Plesk 12 (and I suppose all previous versions) we can't change the SMTP banner to something other than the hostname.But If server host different IPs with different domains,only the primary IP do not have problems for email delivability all other domains are marked spam.This is a critical issue for email deliverability. Very critical issue that should be solved asap.the only solution that we found with our systemists is to remove Plesk, but sure it's not what I would like to do.

here the "problems" start, as of course I don't have the nginx option the question is, where to place the rewrite-rules best?

That's it? I can't use the active sync features ...
I'm wondering whether it is possible to perform a full server migration to a new Plesk server with the same hostname or will Plesk give an error about the hostname being the same?
The new server would not be accessible by hostname (only via IP) until DNS and glue records were changed after the migration.
I know how to do this by analysing the headers, but we have a customers who doesn't believe what we are telling them.
Is there some kind of 3rd party service or script that we can point them to? So they can send an email to the service (or paste headers, or whatever) and it tells them who is the sending mail server hostname/ip?
(The problem is that this customer doesn't understand that all email sent from the server uses the same SMTP server hostname/ip. They are convinced that if they connect to "mail.their domain.com" then this is what is reported as the sending mail server/IP.)
5 hours back I got fails of services mails and then I restart VPS but after few minuts services status up but sites not working.
I contact with support and they told me "Service Named is down on your server".
Any how they update Cpanel, during updation I got email that with subject
Quote:
[ipcheck] Problems with dns setup on server.servername.com
The hostname (server.servername.com) resolves to . It should resolve to xx.xx.xxx.xxx.
Support added entries for me, but sites still not up. They again updating CPANEL. Seems they unable to solve problem.
I have an existing server running cpanel that I would like to change the hostname on. What I am curious about, is the effects on the rest of the server if I go and change it. From what I can tell, the current host name is being used all over the place, and I don't know if cpanel updates everything on it's own, or if I would need to manually update everything after I change the name.
View 2 Replies View Relatedour company is ordering a new dedicated server and we are a little unsure what we should choose as far as the full hostname and nameservers of this one server.
This server will have a couple different websites on it, but really, there is only one BIG website on it... let's call it abcd.com.
While most would pick a hostname of host.abcd.com for instance, if at all possible, we would like the domain name part of the hostname to be something different than abcd.com. We own a domain name that doesn't point to anything yet (unuseddomain.com) and we were wondering if we could use that domain in our hostname.. host.unuseddomain.com.
And instead of using abcd.com as the domain name for our own nameservers (ie. ns1.abcd.com, ns2.abcd.com), we would like to again, use the unused domain name we own (unuseddomain.com) for the nameservers domain name: ns1.unuseddomain.com, ns2.unuseddomain.com.
So...
Will this work? Is this perfectly acceptable?
And lastly...
Since the one website we really care about on this server (the one we got the server for in the first place) is abcd.com, is using the unuseddomain.com for the hostname and nameservers (as above) a bad choice in anyway regarding email deliverability? I understand that mail ISP's (hotmail, yahoo, etc.) do all kinds of checks on hostnames (PTR), etc... and we want to make sure that we aren't hurting ourselves in anyway by using an "empty" domain name that we own as our hostname's and nameserver's domain name.
For instance, if we send mail from the abcd.com account, it will use mail.abcd.com (1.1.1.1) as it's outgoing mail server... Hotmail will see this... do a reverse-dns lookup on 1.1.1.1 and see host.unuseddomain.com. See what I'm saying? It all will work, but will it toss up red flags?
I enter one of my IPs or the hostname belonging to this IP, followed by the Plesk port, and I get redirected to the "main" hostname of the server, which was set in Plesk. But at this moment that hostname is used by another server (my old server) and so I'm redirected to the other server and cannot access Plesk on the new server.
I don't know why Plesk reacts like this, because it did not on the old server. Here the problem more detailed:
I'm just configuring my new server with Plesk 11. My old server uses Plesk 10. On my old server / in Plesk 10 I have the following scenario:
- I have several IPs (10)
- Each IP is used for a different domain
- Each IP has it's domain as the reverse entry (configured outside of the server/Plesk)
- Each IP is set to "Dedicated" in Plesk
- I set Plesk to listen only on one of these IPs (and different port)
- Several domains are created in Plesk, but not a domain for my Plesk IP
- The server's name is one of the domains (required for mails not being recognized as spam)
- The hostname of the Plesk IP is one assigned by my provider (something like x-x-x-x.xyzservers.com)
- Entering the IP of Plesk redirects to the "Plesk hostname"
=> Plesk can be accessed by using x-x-x-x.xyzservers.com:myport
And under Plesk 11 (here comes the problem):
- Still several IPs (but less: 4)
- One IP should be used for Plesk, one for domain X, one for domain Y and the last one for the other domains
- Reverse entries are x-x-x-x.xyzservers.com for Plesk IP, domain X/Y for two other IPs and the main domain for the last IP
- Plesk IP and the two single domain IPs are configured as dedicated, the last one as shared
- At this point I did not configure any domains in Plesk
- Server's name is the same as my old server (the main domain)
=> Entering any IP with the Plesk port redirects to the servers hostname, e.g. my main domain, which is still on the old server.
=> Result: I cannot access Plesk!
Of course I could just change the hostname of the server via SSH (just have to find out how to do this), but why does Plesk react in another way now? Or is the problem that I cannot change Plesk to listen on only one IP?
I have a server that I use to host my primary domain, and I have a cople Plesk servers, now I updated the hostnames of all the servers like
Code: s1.de.myserverplace.de
Now when the plesk server sends a mail it goes in spam always,
In the SPF records of the primary domain sits this
Code:
myserverplace.de. IN TXT "v=spf1 a mx a:myserverplace.de a:s1.de.myserverplace.de ip4:148.251.100.157 ip4:144.76.163.46 ip6:2a01:4f8:201:81b8::60 ?all"
But when I actually send the mail in the headers of the received mail I get this.
Code:
Received: from s1.de.myserverplace.de (s1.de.myserverplace.de. [144.76.163.46])

for <mymailtestacount@gmail.com>
(version=TLSv1.2 cipher=ECDHE-RSA-AES128-GCM-SHA256 bits=128/128);
[Code] ....
How would I set this up so this doesn't happen?

This problem has also occured on another one of my websites on the same server that makes use of mysql. Am I doing something wrong here? I dont think its the script because it ran for years on another server just fine.
although mod_rewrite is active but htaccess i not read why?
and how can i know mod_rewrite is active or not?
(Plesk 7.x)
I am using Windows Server 2003 SP2 Standard Edition. I have installed Active directory and created users and their home folders. Everything works fine except a problem.
When a user from the domain uses the UNC to connect to the server, it shows the shared folder. The user can view and change all other users files, home directory etc. The user can browse all the folders.
I need it to be setup so that the user can only view his own home folder and files and not others. Also when using UNC to browse the server, I want an administrator authentication even if the user is from the same domain.
Here are my current permissions.
NTFS Root folder permission
=================================
Administrators - Full Control
CREATOR OWNER - Special Permission
System - Full Control
Domain Users - Read & Execute, List Contents, Read, Special Permissions.

unfortunately my server crashes a lot recently. What happens is that some application creates a MySQL connection which hangs and then MySQL gets overloaded and takes the whole server down.
My question:
1. How do I configure MySQL to time out even on active connections ? I.e. after 30 seconds kill the process no matter if it is still active or not. Is that possible ?
2. How do I exclude the root user from that?
I've been with Bluehost for over three years. I've really not had any big problems with them. But I've learned that people usually don't have problems with hosts unless they actually have a website that has good traffic.
Well, as my main site has grown, I think I'm outgrowing my host.
I have a forum (SMF) with over 1500 members and close to 80K posts. It's got a good core of very active members. Doing well. The main part of the site is on WP platform.
Friday, I try to bring up the forum and POOF! It's not there. Just a blank screen. No error, no nothing. Call support and they have no clue, but the support guy comments out a line in one of my SMF files and the site comes back up. Don't ask me how he knew to comment out that line or anything.
Things go fine for a few days, then yesterday P.M. I start getting "exceeding CPU" errors and then a 500 error. Keep in mind, I've done nothing to my site in these days to cause any of this or any changes to even make me suspect anything.
Called support two times last night and finally was told to submit a ticket to their scripting department. I could see the PHP errors in my CP and I knew it was something wrong on their end, but no one could figure it out. Well, I haven't heard from support but my site's back up today.
I'm just thinking it may be time to consider switching. Not sure I really want to deal with that, but I'm having more errors and glitches with them in the last year.
I know HostGator gets mostly great reviews. Will my experience there be any different though?
I know lots of people here ask for web host suggestions. I could really use some guidance, not just in companies, but the things I need to keep in mind about my site in particular that would help me choose one.
