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?
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 Replies View RelatedIf 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
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
SIOCGMIIPHY on 'eth1' failed: Resource temporarily unavailable
Tracert/ping from dnsstuff.com to the server IP is normal. A couple other servers I lease (100% identical configuration) work just fine.Kernel

Half C Class on the Server
I am setting up a single sign on system using a ubuntu server with apache tomcat and CAS. My question is a bit more general though.
Clients will log on to a system by giving my web server their username/password and my web server has to authenticate and authorize them. Now to do this I want my web server to send some sort of request to another web server with the username/password and let the other web server check its database and send an ok/not ok signal back to my web server.
How would you do this? My first thought was using certificates to make the communication secure and then use http request and responses but I am not sure if this is actually possible.
I found a couple which i am thinking about at the moment, but what motivated me to make this thread is my current experience with geekstorage.
While the service was friendly and the transfer from my previous host was flawless, i am having a communications problem here that might lead to a disaster. And i explain myself:
When i made the transfer, i asked for a demo account, even for some days so i could test a real account on a real server and not just the links most hosts showcase that might actually be hosted on much better hardware and faster servers.
There was no option for that, but there was the option of me canceling my account at any time during a 60 day period with no questions asked. For varied reasons which do not really have something to do with geekstorage specifically but my own taste of the services, i want to move to a new host. However, even after 2 tickets & 1 pm at the geekstorage forum, i still have to hear back from staff and i am getting nervous because i am closing in on the 60 day mark and i am afraid that someone might be able to take advantage of that. I am not saying that a typical person would, especially since the tickets were before the 60th day, but i have seen a lot so i am getting nervous nonetheless.
This is the last place i would be willing to make this matter public, as i understand it might make some people think badly of geekstorage. This was not my intention at all and geekstorage can really be a great host for you, if it covers your needs well.
But not replying to customers when they request something you shout you provide, while on the other hand, replying lightning fast when ordering or moving is infuriating at least.
I would happily go on and not post this, but either way, i am forced to do so, since i do not know of any other place i can talk with like-minded people on such matters. Sometimes, reviews can be good or bad, this one is bad but not about the services, rather than the way they communicate. Accepting that a product/service is not for you is a good thing and it does not mean you cant suggest a service YOU don't like to someone else that might do. But such ways are bad anyway you look at it and do not warrant any suggestions.
And keep this in mind. Even if someone from geekstorage replies to this thread, what will their excuse be for not replying FIRST at my tickets (and any other tickets for that matter), but at a friendly forum?
People expect to have the same kind of service as they get on day one. If you are only motivated to bring customers in, then you wont keep them for long, that's for sure. I was expecting the same kind of service i got on the first days, which i didn't.

How to close any communication between the server and some hosts/domains?
So there won't be any in/out connection between the server and those domains?
can APF firewall or mod_security do this?
I attached a service node to PPA using public key by following [URL] ....
But when I check tasks, Configure PA agent on node 'ip-10-0-0-24' fails with message: SSH communication error: SSH auth via password failed
I correctly configured ssh by pub keys. I can SSH into service node with ip 10.0.0.2 from PPA management node without any issue.

I'm running CentOS with Paralells Plesk bundled Paralellls Premium Antivirus (Dr Web). After the latest yum updates DrWeb continously seems to crash and be restarted by the Parallells watchdog. By default there were no logs for DrWeb, but when I enable logging to a file it gets spammed continously with the following error:
Cannot create pipe for communication with scanning childs (Too many open files)and the Drweb process runs at 99% CPU for long periods. This totally fills the disk with logs and I've now disabled logging again and Drweb is back to continously being restarted by the watchdog.
I have a server that has multiple IPs, one of which I'm using for a VM that is bridged.
The issue is, internally, that IP is trying to point to itself rather then the bridged nic (which is technically a whole other server plugged into the same switch, logically).
I think I know why, I just don't know how to fix it. This is the config file for the ranges:
Quote:
# Intel Corporation 82546EB Gigabit Ethernet Controller (Copper)
DEVICE=eth1
BOOTPROTO=static
DHCPCLASS=
HWADDR=....
ONBOOT=yes
IPADDR_START=....243
IPADDR_END=....254
CLONENUM_START=0
GATEWAY=....241
NETMASK=255.255.255.240
NO_ALIASROUTING=yes
(edited a few things out just in case)
Basically, there's a start and an end, is there a way to exclude an IP?
When trying to access my webpage (www.avillafan.com) i get this message:

It shows that there are big problems with ultimahosts. I am observing more of such issues recently amongst many companies. Is this something to do with the current economic situation?
I am getting 500 Internal server error.What may be the reason ?
The site was running fine till yesterday.
I run a proxy. First, I was on shared hosting. Worked for 2 months. then, bam! 500 internal server error.
I moved to a smaller VPS with 128 MB RAM. Worked for 30 min, then 500 internal server error again...
So now I moved to a larger VPS with 512 MB RAM, 1 GB burstable. Worked for 2 days, and now the 500's is back...
Rebooting the VPS usually fixes it, but I can not be sure I can continue rebooting it, as I expect it getting worse later.
It usually starts with lighttpd goes insane. One minute it's using 30 mb RAM, ok that's good. Then suddenly it uses 300 mb. then 500 mb. Then the 500 internal server error occur.
So any ideas of how I should configure this so it would work in a better way?
This is filled in the error log:
2009-06-02 13:21:16: (mod_indexfile.c.182) file not found ... or so: Too many open files / -> /home/admin/datashelf.net/
I just assume my files in the server of my website has some virus.
so i just delete all the files and upload it again.
But after i upload it website doesnt open.
Why?It shows the message 500 Internal server error.
How can I fix an internal server error?

View 5 Replies View RelatedI have two separate C-class IPs in my vlan and use one single gigabit switch for the uplink and internal/external traffic.
Since last month, I noticed that internal traffic is included in my bandwidth usage. Somehow, traffic from server A to server B is billed! The strange thing is that the traceroute is showing that traffic is not going through the routers, its one single hop.
So I am really wondering how this is possible. Could it be that the provider has changed some vlan settings to let me pay massive overage fees?
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.
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 useing lighttpd for my website,my site Only picture.
but if access peak , There are often 500 Internal Server Error,
I have six dedicated servers on a VPR. I use one of these as the Database server and the other five connects to that server to read the Database.
When I setup my scripts for the first time I used the external IP to connect to the DB server. Everything worked perfect for these weeks:
mysql_connect('174.xxx.xxx.xx', 'user', 'pass');
Since three days ago I finally received the internal IPs of my servers and now I use the internal IP of the DB server:
mysql_connect('10.0.0.1:3306', 'user', 'pass');
When I did this last change this my database started to collapse. Queries stuck on a bottleneck every 10 minutes. Here's an example:
40468 simon 10.0.0.7:47002 pkindigo_db Query 115 Locked update `captured` set hp_left = '79', status = 'normal', att1pp = '25', att2pp = '30', att3p
40523 simon 10.0.0.2:58080 pkindigo_db Query 115 Locked update `captured` set experience = '5120', level = '16', hp_left = '58', hp = '58', status =
... (tons of locked queries before) ...
As you may see table is locked since 115 seconds for a simple update... after some hours this ends on a "#1135 - Can't create a new thread (errno 13); if you are not out of available memory, you can consult the manual for a possible OS-dependent bug" and even some of my tables finally crashing.
I think that my Database stuck because of a DNS lookup delay. When I had this problem before using the external IPs, I added skip-name-resolve and the problem was fixed. But now with the internal IPs it seems that's not enough.
my friend is getting frequently 500 - Internal Error on his sites when ever he starts to get good amount of traffic at a moment, and by the time it resets to normal more than half the traffic is lost, he is using wordpress blog, some other applications not of any traffic, an IPB forum, and some other image hosting script
in total he has 3 databases used, he's not running to outage of RAM, he is using max.
70% of RAM at the pt. when this occurs, checked once long way back..
he usually gets lots of traffic to blog and image host as he posts some real good stuff..
