I have problem on eth1 for local IP. Eth0 is public IP behind Firewall, and eth1 is local IP for backup and for database. Every time eth1 is on, eth0 cannot be reached by ssh and http, although still can be pinged. Eth1 is also IPMI BMC port, and automatically got IP from DHCP LAN for web-based IPMI access, and the IPMI cannot be turned off. Motherboard is Tyan B7002.
View 2 RepliesIf i have 2 NIC on my server 1 for private and 1 for public
if the public is eth1 than in the config of APF
IFACE_IN="eth1"
IFACE_OUT="eth1"
I should set it to eth1 instead of eth0
is that correct?
thanks
In a linux webserver how can you setup two servers to communicate via eth1 rather than eth0. We wish to use eth1 for internal communication between our public webserver and our database server. So that we do not incurr charges on the public switch.
How can we do this?
One particular server I have out of a few (same data center / network) is acting up network wise. The server load is minimal, so its not that. The NOC confirmed no network issues either, which makes sense since its one server out of about 4 that have this issue. All have the same exact specs, o/s, Cpanel, etc.
root@server [/etc]# mii-tool
eth0: negotiated 100baseTx-FD, link ok

Tracert/ping from dnsstuff.com to the server IP is normal. A couple other servers I lease (100% identical configuration) work just fine.Kernel

I run multiple domains/sites on my linux server. I know there is a php.ini files that comes with the php installation package. But I have heard that there is a way to create a local php.ini file for each domain.
Does anyone knows how to create local php.ini files for each domain. Is there a special setting i need to do to make it run?
in my rc.local i've got it so a program starts up automatically, this works when i restart my machine but the machine has also been crashing randomly (something which i haven't tracked down the source of yet) and when it goes up after this the program isn't started. Could this relate to my crashing problem or would it be something else that isn't configured right?

View 13 Replies View Relatedhave only done static html sites in the past, but am ready to branch out and learn php and mysql. I have watched numerous video tutorials on php,mysql, dreamweaver cs3, and how they all work together.
I have followed all the steps on the tutorials and the website works great on my local testing server, but how in the world do I get it to work live on the internet! This is probably a very stupid question but I am at the point of not caring about looking stupid. I just want to know what Im missing/ doing wrong. The website is hosted with GoDaddy, (and the domain is registered with them as well).Am I supposed to have something set up there or a different server? I have tried using ftp to transfer all files over to the domain but when I visit the domain, the php pages do not work.
wasn't sure if this should go into "technical" or "programming" but I figure someone here will instantly be able to tell me...
(details: I'm on a shared host with cpanel and centos 3)
My hosting service techs refuse to update gnu TAR on the server even though it's several years old at 1.13 and has some know bugs that are annoying for complex calls - (basically the techs use any request like this to try to upsell me to dedicated or VPS which I don't need at my low level)
So I'd like to install a "local" copy of the newer gnu 1.14 or 1.15 TAR (which I *think* is possible?) into my account and have it run instead of the shared copy?
Unfortunately this is beyond my knowledge so thanks for any help in the right direction...
Okay, so here's the issue. I've been searching for a solution for about a week now, and just can't seem to find any information. The company that I work for had me switch their site live so I went through and changed the DNS information and pointed the A records to the new server running an online store. I waited and waited and waited for the propagation to finish so I could keep working on developing the site. I talked to our hosting company and they assured me that they were being pointed to the new server and there was no issue. I changed the DNS on my own computer to point to openDNS and I could see that it did in fact change.
We are now two weeks into the change and we can still not view the site from our network. I am in need of any ideas you can give me! If you ping the site with the default DNS server you receive the old IP Address but if you ping it with the openDNS IP in place, you receive the IP of the new server. I've gone through and run a /flushdns, /release, and /renew. I am working from a mac so advice geared towards this would be helpful however, I do have access to several machines running XP.
Again, the site has propagated across the internet, just not in our office.
I look forward to and appreciate any insight that you can offer with all of your eclectic wisdom.
I am really thinking of upgrade my dedi server, but since its from a IDE disk to a SATA, I can´t move the IDE to the new system.

I have been working on an online shop locally from my machine, using Visual Web Developer and SQL server.
This is working fine, but now its at the stage were i need to show a client. In order to do this i need to upload it to our servers.
What i cant get my head round is the connection to the sql server, do i need to upload this too, or can i somehow point the connection string to the sql server sitting on my local machine...
Is it easier just to upload an sql server? how would i go about this?
I will have two servers (both centos), one is web server, the other one is database server. I would like to set the db server (mysql server) not accessed by the public internet, but web server only through an internal IP, like 10.x.x.x

I have a client who needs a very special configuration. We are trying to find a data center or server provider in Switzerland who can only broadcast there ip in Switzerland only. So any attack or anyone trying to access that ip outside Switzerland will not get even close to it...
View 3 Replies View RelatedI have a script running on my server that has access via port 1031, but I would like to block access to it from the public, and instead allow access only through a php proxy script on my server which will connect to port 1031 via 127.0.0.1 (i.e. 127.0.0.1:1031)
So some may be thinking why? Currently users gain access by heading to mydomain.com:1031 . However I would now like to include adverts along side the script (but can't physically make adjustments to the script as the company that made the script has vanished of earth)
So the only way I can think of doing this, is by having the adverts in an Frame next to the proxy script.
So does opening up access via 127.0.0.1 just for this case, give me security problems?
I have a client that is using proboards.com and they are tired of all the ads / limitations. They want to migrate to their own copy of SMF but they have over 1000 users and tons of posts.

I have a problem with SSH. I can't login from outside the local network.
Software:
Centos 5.2 X86_64 + virtuozzo 4 (fresh install)
Already tried:
checking sshd_conf, everything is right
Checking nameservers and network setting (look fine)
Stopped iptables service
Problem:
Eth0 have IP xxx.xxx.xxx.xxx i can ping this ip over wan
Eth1 have a lan IP 192.168.0.10
Those two ips are listed in sshd_conf.
Ssh worked fine over lan/eth1. From a extern host i can ping the eth0 ip, but not ssh over that IP. (get a timeout)
Also new containers are pingable but ssh doesn’t work. (firewall off) Webinterfaces are working well.
Hope someone have a solution, this is pretty frustration i have search over 2 days for a solution, this must be a simple thing (i hope)
I try to enhance my server security and prevent local hack but it seem useless.

Anyway to prevent it completely?
From last 2 days I am trying to browse a website locally in FC6 but not getting any sign of success, this site is not live yet.

I am trying to assist a customer install a Dolphin CMS but it returns some "open_basedir restriction in effect" on /usr/local/bin/php (it needs the path to the PHP binary).

All the summers the same thing, problems from the locals ISPs affect us because some users can't connect to their websites. If they manually change the dns can do it, but someones don't want to understand it.
I want to ask you if you know any solution, or see any error in my dns configuration.
1. I setup the dns entry on the domain registration service like : ns*.domain.com
2. domain.com it's my main domain only for dns
3. then I setup the servers with ns15.domain.com for the main ip and the secondary ns16.domain.com for example with the next ip .
It's possible to setup more dns to prevent this? or setup dns in another servers? something like geographical dns? or configure servers to resolve from others dns?
I live in Australia and a lot of my websites get their base traffic from the United States; therefore I have a dedicated server in the United States.
In a few months I will be developing a website that is mainly for Australians. I'm wondering if it would be better to seek Australian hosting just for this site or just put it on my dedicated server in the U.S.
Personally I don't really notice the difference in load times between websites hosted in different countries but it may add up in the long run.
The reason I am leaning towards the U.S dedicated server option is that I have full control over the server. (i.e what php modules and extensions are loaded).
I utilized xammp to set up a local hosting enviroment on my desktop. It included Apahe, mysql and php. Apparently php support has not been properly installed on my web server.
How do I do that?

Currently, I'm using Dreamweaver to create a website and I have had no problems of uploading my files to a site through Dreamweaver before. But I will not have access to my computer for about one month every year. However, I have a laptop available during that month.
