Adding Internal IP's To Servers
Dec 12, 2007
I'm in the mid of working out some issues I have with linked servers. I was wondering what the best method is to add internal IP's to my servers?
This is what I did:
/etc/sysconfig/network-scripts/ifcfg-eth0:10
In there, I placed:
DEVICE=eth0:10
IPADDR=192.168.1.100
NETMASK=255.255.255.0
ONBOOT=yes
Saved, and then:
/sbin/service network restart
====
Have I done this correctly? If not, what's the correct way of adding the internal IP addresses? My servers are linked together via an Ethernet cable.

How do I go about adding new whois servers in my linux box so that the "whois" command can work for those domains? I notice I can't get any .me information now.

We offer colocation & dedicated servers as well as shared & reseller hosting services.
Our colocation customers and dedicated server customers are definitely on their own VLANs for obvious reasons.
Up until now, we have been using separate VLANS and ip allocations for each of the servers in our shared & reseller server fleet. I'm starting to question this policy for many reasons:
1) We directly manage all of the servers and it is very rare that any servers are compromised to the point where they can steal an IP address.
2) We are wasting IP addresses - network, broadcast and gateway addresses are required for each vlan. Additionally, if a server needs 1 more IP address, we need to add a whole new block.
If all of the servers are under our direct management, does it make sense for us to use any vlans at all? It seems that it only serves to complicate things, waste ips and add management overhead.

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?

about adding IP addresses to cPanel.
I've added 8 IP's to my WHM, and I am slightly confused...
I moved one domain to the new IP address and it worked fine after 15 minutes. I then moved another to a new IP address and it did not work after waiting over 30 minutes. The only difference between the two accounts is one account has 2 domains attached to it and one has about 15 domains attached to it.
If I just were to leave it sitting and wait would it switch to the new IP?
I would have no problem with waiting except for the fact that it resolves to the "cPanel/WHM is now installed" screen, rather then the website.

We all know that our localhost can be accessed at 127.0.0.1 or your the IP assigned by your NIC which starts from 192.168.1.2 (or 192.168.0.2 in some cases depending on the router you use).
My question is that, how do I map the other IPs 192.168.1.3, 192.168.1.4, 192.168.1.5 etc. etc. and have them point to my localhost?

My server in the datacenter has to migrate to new IPs. Is it feasible to add new ip and gateway and have that operating on eth0 -- doing it remotely?
The dc said I can have both IPs concurrently working for the next 10 days or so.
But, I'm still unsure if I can safely set the new ip and gateway on the server remotely.
Any help would be appreciated. Of course, I have logged a ticket to see if they will set my new primary ip from the console and all the virtual interfaces ...
But, would like to know for my own information if this process is doable remotely.

I currently have a private server in my office which has cPanel and APF installed. The server only allows one static IP to access SSH, at the moment I'm away and don’t have a static IP on my current ISP connection so cannot access SSH.
Is there a way to add say 123.456.000.000 which would allow all IP's in the 123.456 block?

Heres the setup:
BoxA has 123.123.123.123 as its main IP
Request another IP allocation from provider, they grant it, how do I add 124.124.124.124 to the box (preferrably without a reboot required) so it is pingable/loadable etc?

I installed mssql support to my cpanel server as you mentioned on cpanel forums. When i request some data it gets charecters in error and writes them to mysql server.
I've installed this on previous server and didnt have this kind of problem.
I set same configs with old server (mysql.php,etc.) but it's not working.
[ http://forums.cpanel.net/showthread....ighlight=mssql ]
cPanel Ticket Message;
we are still having same problem on mssql, there are difference with 2 dedicated but we did not solved it yet. for example, you can see on first screenshot, there is some character errors while it getting datas on mssql server and we think that, it will cause problem and not showing totals but we did not have any problem on old server without characters problems

I installed Fedora Core 4 from the DVD included with the "Run Your Own Web Server" book. Everything went great.
Now I need to add IMAP to PHP. This has proved very difficult, as it seems that the sources are not provided. I downloaded the latest Apache and PHP and tried to build with the same configuration used to build the ones that came with the book. (Apache went fine - the module inclusions are done through the configuration files. PHP is not going well at all - I grabbed the ./configure options from a phpinfo() call, and it just barfed all over the place.)
Simple question: is there an easy way to get the IMAP into PHP without going through the recompilation?
Simple answer: Install the PHP-IMAP RPM. I sure made this a lot harder than it need to be.

how i can add a dedicated server service to my website. Im looking for something that will possibly give me something with bandwidth graphs and monitoring. And an easy way for our customers to tell us to reboot possibly. I currently use WHMCS so maybe you guys might know of something that will work with whmcs?

I have a domain name that I registered with 123-reg.co.uk, and have pointed the domain to my name servers of my host, but when I look at the dnsstuff report it comes up as not having any "Glue" for the name servers. 123-reg gives control to me to edit the domain name options (A, CNAME etc). Can anyone help me in resolving this. the url is mobcontracts.co.uk

Trying to install the GD graphics library to a linux box.
Downloaded the file gd-2.0.34.tar.gz from [url]
Ran gunzip and tar thus expanding the files to a temp directory - as root.
The instructions say to run ./configure
I ran "sh ./configure" and I get the following:
Quote:
checking build system type... i686-pc-linux-gnu
checking host system type... i686-pc-linux-gnu
checking target system type... i686-pc-linux-gnu
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking if we are building a Cygwin target... no
checking for gcc... gcc
checking for C compiler default output file name... a.out
checking whether the C compiler works... configure: error: cannot run C compiled programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details.
why the configuration fails?

I have setup a new cpanel/whm server. The main IP address works fine and I added the additional IP addresses the datacenter gave me.
That was yesterday, today I logged on and when I go to IP Functions >> Show or Delete Current IP Addresses all the addresses I added yesterday are showing up in red text and I cant ping any of them, not even if I ping them from the server itself. Seems that when I rebooted the server after the initial cpanel setup something has caused this.
Trouble is my name servers are sitting on 2 of the malfunctioning ip addresses so they aren’t working at all.
I have tried removing them ad re-adding them and they still show red.

Since they had opened it up to everybody, I am adding Google Adsense for domains to one of my spare domain names. I am unable to edit my A and CNAME records myself, so always just email my host to do it. The setup guide is here and my host is having problems.
Google wants you to setup 4 different A records, but my host claims they can only do one on a shared linux server running BIND DNS.
Is this just a limitation of using shared hosting or are we missing something obvious? Why can I not just add one of the A records and miss out the other three?

I run a Perl/CGI script from a Web page to download some files located in a Linux server. When I click from a Windows XP on the link of the file to download via this Web page (IE), a dialog box will be displayed to ask me to "Open" or "Save" the file (.txt, .doc, .xls,...) but for some extensions like ".dat" or ".asc", the dialog box ask me to save it only and I have not an "Open" button.
I tried to configure Apache to add these extensions as text/plain by adding these lines in http.conf:
AddType text/plain .asc .txt .dat
How can I add these extensions (.dat, .asc and other extensions) to Apache configuration to be able to open it with Textpad or Notepad?
I hope that the users will be able to open it with Notepad or TextPad without saving it. I know that we can add this type directly in the stations XP but I have a lot of users and I cannot manage that. I hope to perform it from the server. I think something is wrong or missing in my AddType, AddHandler or LoadModule?

if typically you were to add an additional (third) hard drive (SATA) to a server, would it add any additional string on the CPU?
Assume that there is no extra disk usage - meaning that static image and html files off disk two are simply moved to disk 3.
