I am having network issues, local servers in the /24 are unable to connect to VPS's.
If I make the /etc/sysconfig/network-scripts/ifcfg-eth0 too especific by adding a netmask then Nodes with assigned IPs on a different /28 will stop working/ping.
Right now it works, but it doesn't allow local servers to connect to VPS's (a problem) as one of those nodes is a VPS backup center.
my servers and they have a minimal list of settings in the ifcfg file. I am using centOS so it is ifcfg-eth0 and ifcfg-eth1.
Anyway, here's one of them from a REL3 server.
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=static
IPADDR=xxx.xxx.xxx.xxx
NETMASK=255.255.255.240
GATEWAY=xxx.xxx.xxx.xxx
And the one I just saw when I did a fresh install of CentOS 4.4.
DEVICE=eth0
BOOTPROTO=static
BROADCAST=xxx.xxx.xxx.xxx
HWADDR=xx:xx:xx:xx:xx:xx
IPADDR=xxx.xxx.xxx.xxx
NETMASK=255.255.255.240
NETWORK=xxx.xxx.xxx.xxx
ONBOOT=yes
TYPE=Ethernet
So since I'm trying to learn what I'm doing here, what lines are actually needed and why does one setup have extra settings?
If 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
I'm not sure if the trafic showed by munin graphics is normal or not because it seems it jumps to 2mbps in the morning and after few hours drops down to .5mbps
I don't host any storage websites, which should have lots of uploads, just normal websites, maybe a total of 10000 unique visitors/day on all accounts (I estimate this as I don't know how to find out exactly the number of visitors on all websites hosted on this server - 182 accounts)
My question is how can I see what exactly is making that trafic, maybe using a netstat command to see what processes are using the bandwidth.
How can change "eth0" speed to 100mbps and full duplex?

There is a problem after that. 2 of the server actually was OFFLINE by 12 midnight sharp yesterday night. This is the second time (second day) it happens.
I went into the datacenter and
#ping yahoo.com
*Host not found*
#service csf stop
#ping yahoo.com
*Responding*
So how is this related to eth0 making my server offline by itself? Was it Iptable problem or Csf problem? or Kernel problem?
I rebooted my server and now munin is not showing any eth0 traffic. All other graphs are fine. I can see there is a ton of apache accesses so there is definitely eth0 traffic. Munin logs report no errors. I restarted munin and munin-node. I even did 'yum remove munin munin-node' and reinstalled again but it still doesn't work for eth0.

Does anyone here know where Fast VPS Nodes Providers are?
View 9 Replies View RelatedToday I was just going through some pricing and quotes trying to decide if multiple average priced servers ($150/mo - $400/mo) vs Powerhouse servers ($1,500/mo - $2,500/mo).
The powerhouse servers look mathematically to pay off better in the end but I am thinking that they may bottleneck easier.
We are interested to know how many VPS providers.. ( not resellers ) have hardware firewalls in front of their VPS hardware nodes?
If so, Do you find this impacts customer vps's?
What kind of hardware firewall do you use?
If not, how do you protect your hardware nodes from attack?
After some research I seem to find most providers do not in fact have any hardware firewalls in front of their VPS hardware nodes. Mostly they say it causes too many problems and tickets due to port blocking, etc... and customers complain about being restricted..

View 3 Replies View RelatedShould excess bandwidth charges apply for traffic that occurs between 2 nodes on a lan?
We have 2 self service dedicated servers. One of them runs our production environment and the other is used for development and backups. We have a cron job which copies backup data from the production server to the development box. A few months ago a bug in our backup script resulted a $700 excess bandwidth charge from the hosting provider.
An analysis of the network stats showed this to be $350 for outbound traffic from the production server and $350 for inbound traffic to the development box. Internet traffic for the period in question was negligible. I disputed the charge but was unable to obtain a refund. I'm trying to decide whether to switch providers as a result.
Based on the information listed above what do you think most hosting providers would have done:
1. Exactly the same. The terms of service make the customer liable for all excess bandwidth.
2. Offered a $350 refund to avoid billing twice for the same traffic.
3. Refunded the full amount because the excess traffic did not touch the public wan.
I'm testing PPA and have now a questions. How can restrict a subscription to a service node? I have try that over the subscriptions and custom atribute's. That work for the most thinks (Apache/Postfix) but not for MySQL, all customers can by a create to choose the database server (all database servers). How can i customer don't allow to choose the database server?
For a example (web1, mail1 only -> db1) (web2, mail2 only -> db2)
And for the DNS settings to create automaticly a DNS for the database service? (as a sample: db.domain.de -> database service node)....
I can't seem to find if there is a way to specify what hostname is used for a service on a service node. For instance, if one creates a service node named web01, and makes it a DNS service node, is web01 what will be used when creating NS records in zone files, or is there a way to change that?
The ppademo.com site is offline (and was unlicensed again last week).
after learning that server aliases are not available for PPA, we are needing to rename our service nodes. We have looked through the documentation, and did see the ppa.hostname command for the management node but there does not seem to be an equivalent for service nodes.
View 3 Replies View RelatedI'm attempting to run PPA on Azure but I only have one IP to work with, the public IP address. It's not possible to communicate between servers using the internal IP addresses as they are not necessarily on the same sub net. How can I get PPA and service nodes running on a single IP address per machine?
An example of the error I get when setting up a service node is

how do you set the hosting type for the subdomain?! I don't see this in the docs.
I am working on a new install of PPA, and after installation on the management node Im trying to add the other nodes. Ive tried to add a Apache, Postfix, DNS & DB node, and they all have the same issue. The installation task fails with the following error:
Destination host 'node.domain.com' (#3), IP '192.168.1.*' : The operation can not be completed because the following component is missing or is not running: pleskd (sc_name '', sc_id #45)
(domain and IP are removed here, correct in the original error. The IP is a backchannel IP, and the public IP was properly set in the management node).
I've verified that pleskd was installed and is running on each node:
Code:
24710 ? S 0:00 /usr/local/pem/sbin/pleskd --props-file /usr/local/pem/etc/pleskd.props --send-signal
24712 ? S 0:00 /usr/local/pem/sbin/pleskd --props-file /usr/local/pem/etc/pleskd.props --send-signal
24714 ? S 0:00 /usr/local/pem/sbin/pleskd --props-file /usr/local/pem/etc/pleskd.props --send-signal
...
I've verified that my management node can connect to the nodes in question via 8532:
Code:
]# telnet 192.168.1.* 8352
Trying 192.168.1.*..
Connected to 192.168.1.*.
Escape character is '^]'.
^]
telnet> quit
Connection closed.
So there shouldn't be any firewall or other networking issues.
What else can I try to get this running?
Is there a KB (I couldn't find one) - to implement rate limiting for receiving mail on our service nodes?
Just had another customer account compromised (not a very weak password either) - and that meant > 250,000 emails - a LOT of cleanup.
Not only do we need rate limiting, but we also need notification of potential abuses.
any experiences to report about purchasing used / refurb gear from either Network Liquidators (nweq.com) or Network Hardware (networkhardware.com)?
View 12 Replies View RelatedOkay, I have been trying to get a VPN network setup here between our DC and our office for weeks now and have not been sucessful.
Here is our goals:
-use 10.x.x.x/255.0.0.0 as a local backend network at our DC
-be able to assign a 10.x.x.x address at the office to all workstations and be able to access any of the local machines at the DC
-we have a asterisk server that we use and want to run that on the same network, asterisk box at the DC, phones at the office
We are wanting to impliment this for allot of security procedures and for ease.
But I also want to be able to have this like at my house so I can still be on the VPN. I want to have my house, office and DC always connected and then setup remote ability too to dial in via VPN.
What would be the best way to accomplish.
I have already tried having a few Linksys RV082 and WRV54G but the remote and local networks must be different networks, so this will not work here.
Does anybody know how can I determine which of the IPs within the network are used or not. I know that this can be archived by pinging each of the ips but there are 256 (192.168.1.0 - 192.168.1.255). I am using CentOS 5.

I have some VPS with Knownhost and i use it for hosting purposes.
First, I'm not from USA.
Here in my country we have several ISP but one of them ( i guess the biggest one ) is having problems with their link that connects to another countries ( including USA ).
Many of my customers that uses this ISP complains about their site being down and also slow download speeds ( 10kb/s when they usually download at 200kb/s ). When they run a traceroute i see that the problem is related to the ISP.
I have already contacted the ISP but they doesn't seen to "care" about their clients and i guess they won't solve this in a near future.
My question is if there is a way to solve this problem on my own?
I was thinking about getting a link with another ISP ( the one that really works ) with static IP and route this to Knownhost VPS. I know that this isn't a cheap solution but is it possible?
To make it simple, I am having some bays with dedicated servers. We offer 2 possibilities for bandwidth traffic: per Giga, or per MBit/s but I am having some problems. We currently use the router of our ISP better than buying a cheap low quality router.
- How can I know how much bandwidth does use on customer and how to limit if I have no access to the router ?
- How can I limit my customer from using free IP on the same block than he is ? We do configure server with IP and the same subnet, gateway and broadcast, so one customer could use free IP just so, and I would not even be able to know who is doing.
How do you limit and count this for your servers?
