I have a question maybe someone can help with. Is it possible to set the IP address on a IPMI card before a system ships? That way when the customer gets it, it already has the IP address set to whatever was agreed on and they can log right in using that IP address?
The card is a supermicro Supermicro AOC-SIMLC
We've been investigating software and appliances that would allow us a central, web based login to manage access and users to all the servers with IPMI cards. Does anyone use anything other than appliances from avocent or raritan?
View 2 Replies View RelatedI am having alot of difficulty trying to setup supermicro IPMI.
I am using motherboard PDSMI+.
Ok, so this is what I did:
1. I flash the IPMI card with the cd-rom that is included. I set the correct IP and MAC address.
2. I then install OpenIPMI-tools
I was able to successfully issue the command locally:
ipmitool sensor
but, when I try to connect remotely I always get a connection failed. I tried everything I know, which is nothing and got no progress.
I set the ipaddres and gateway by using this commands:
ipmitool -I open lan set 1 ipaddr [IPADDR]
ipmitool -I open lan set 1 defgw ipaddr [GW IPADDR]
ipmitool -I open lan set 1 netmask [NETMASK]
ipmitool -I open lan set 1 access on
I'm tired of our current method for doing this. Is there a program out there that can do IP management aross multiple subnets and many thousands of IP's?? I cant seem to find any that either dont cost an arm and a leg, or is just software. All the ones I find tend to be appliances, which isnt what I want.
View 2 Replies View RelatedNot sure on industry standard here, but I am now curious about this issue.
I placed an order with a company, paid for a setup, first month etc. On receiving the order, I was given the wrong product. Which was fixed for me within a few days. I was happy to even pay for this which the host declined.
Fast forward a week or so. Still in the first month, and issues are still not resolved.
I've now removed credit card information from the billing system (yes I know, shouldn't do it) with good reason. I expected to have to pay another month, and that was fine.
Anyway, month ends and I am charged on a credit card that was removed from the billing system. When confronted about it, I was told standard practice. I think this is highly unethical to hold details after they had been removed.
Is this indeed standard practice in this industry? Do a majority of other hosts do the same thing?
Now again, I am only to happy to pay another month, just not from a credit that was removed, which is why it was removed. I would've sent a check, or done a deposit. I do understand that fraud, etc is very high in this industry. I have a host or two not give me service because of the email address I used during sign up, but when changed, I received service.
i have several servers here but only basic knowledge about raid
My understanding of raid is like this
I have a server with 4 disk on it and if i put it in raid 1 and want to install an OS i can only see 2 of the disks right? (thats how it works on my ibm server)
But with my other servers if i put them in raid 1 and want to install OS i can still see all 4 disks thats not right is it?
anyone that can recommend a pci raid card for 4 sata2 disks?
What are the benefits of IPMI with KVM Over LAN? Is it more of a benefit for the datacenter? Or does it have benefits for someone that has collocated there server a far distance away?
View 14 Replies View RelatedThis may appear to be a stupid question, but I just wonder if the Supermicro IPMI cards work only with Supermicro hardware (or if it works also with other hardware, but without warrantly)?
In case does it exist some hardware independant, or something similar?
The issue we have is that server1 (web) has the load very high, compared to server2 (mysql). Sever2 stays at 0.5 during peak time.
I must mention that we have very heavy traffic hits only for 30min/day, then things calm down.
I simple diagram would be:
[USERS] <= NIC1 => [SERVER1 WEB] <= NIC2 => [SERVER2 MYSQL]
So I think we can install a load balancer and upgrade the NIC cards, in order to solve this problem.
What I thought is this:
In server1 (web) install 2 NICs, one facing the users and one facing the server2 (mysql).
Currently we have a 100MB NIC card into each server.
The 95th is way to high at peak time, over 500MB so I was thinking on installing a 1GB NIC facing the server2 (mysql).
My question is:
What is the best way to install a second NIC into an existing configuration?
Do I need a Cisco 2970 switch?
Example:
[USERS] <= NIC1 | NIC3 => [SERVER1 WEB] <= NIC2 => [SERVER2 MYSQL]
to setup a Windows server that can support the failure of the switch that comes before it in the network diagram. The idea would be that if the 15A circuit the switch was on failed, or the switch just died, the server would still be online.
I already have two switches in spanning tree just before the server. Is there a way to assign a single IP to the server on both its network cards and connect each card to a different (spanning tree'd) switch?
I am setting up an internal network for management only. So, assign an IP for the second NIC, and activate it, but it seems not working. I have tried this
#ifconfig eth1 192.168.2.14 netmask 255.255.255.0 broadcast 192.168.2.255
#ifconfig eth1 up
checking dmesg, it shows the NIC is up
# dmesg
ADDRCONF(NETDEV_UP): eth1: link is not ready
tg3: eth1: Link is up at 100 Mbps, full duplex.
tg3: eth1: Flow control is off for TX and off for RX.

Will the Dell-made PERC 4 DC (or SC) RAID cards work in Sub v20z servers?
The Sun v20z specs :
[url]
From what I gather, it should in theory work, as they are both PCI-X and Ultra320 SCSI ... right?
If they won't work, can anyone recommend any raid cards that will?
With Ubuntu getting more and more popular, anyone knows what are the raid cards that support Ubuntu?

I'm in the market for a new server for colocation, and to save myself some of the headaches I've had with my current one, I'd like it to have a good remote management system, specifically one that operates independently of the operating system, or ideally one that can be accessed even if the machine is powered off. What exactly should I be looking for? I've read a lot about IPMI and Intel vPro and AMT, and I'm not quite clear on how they all fit together.
At the very least, I need something that will let me power-cycle the machine and remotely access its serial console. All the hardware environment monitoring things in IPMI sound useful, but not essential for my purposes. Anyway, it sounds like vPro is part of many (or all?) current Core 2 processors, or am I mistaken? I'm looking mainly at machines with Core 2 Duo or Quad, so can I expect they'd have that built-in, or would I need to specifically request it or look for some particular chipset or CPU?
I am going to purchase SuperMicro server with IPMI card which I can do remote control...but should I add KVM swtich for extra backup?
If so, what kind should I get for 1-3 servers? IP based? Any recommendation?
I have linux dedicated server and like to setup dual NIC cards for extra redundancy.. in case one NIC card fails.
I have no idea how I can set this up..how can I do this? I understand at least I need swtich.. and?
I have a bunch of servers with IPMI cards with KVMoIP capability and I know how to configure IPs and everything using IPMICFG.EXE while the system boots.
Now, I am facing a dilemma as to how to create the IP space.
When I create a user I specify the user has no access to change the network (IP) info.
But say the user has windows server, are they able to change the IP from there using IPMICFG.EXE?
This will determine how I create my VLANs.
If the client with USER access is able to change the IP settings using IPMICFG.exe then I have to create a /30 VLAN for each KVMoIP. I dont want to do this cause 3 IPs are wasted.
If the user will not be able to execute IPMICFG.EXE then I can just create one big VLAN and assign one IP per IPMI card with the gateway being the same for the entire big VLAN.
I have here 3 servers of Tyan with M3291 IPMI boards installed. I hooked it up as per instructions of Tyan, but am unable to get it to work.
I have tried contacting Tyan about this, but after a few messages they stopped responding to my questions. I think they are convinced it is working with me....
The setup is;
- Ubuntu 6.1 x86_64
- System BIOS is the original version
- IPMI card is flashed with the correct firmware
- The network port which is shared with the IPMI card has a different IP address then the IPMI card.
Settings IPMI card:

If I use the IPMI utilities I am unable to contact the board and do anything with the server....

Does anyone have this combination working, and how did you do this?
I was wondering if there's any web hosts that offer 3D graphics cards in their hosted dedicated servers? they don't have to be that great of 3D graphics cards just better graphics than the normal video cards that they usually put in them?
View 14 Replies View RelatedI have a SuperMicro server with AOC-SIM1U.
I was able to login from IPMI View just fine, and everything works as expected except
"Text Console ". I was able to hit the start button and get the black screen on IPMI View, but that was just about it.
Only a cursor blinking without texts.
Is there something else that I should do in order to get text console working? I've tried all baud rates.
When you can't access your server via SSH or Remote Desktop, what do you use to fix the problem without filing a ticket?
IPMI?
Serial console?
KVM over IP?
Dial up connection?
Backup network connection?
Get up and walk to the server? :-)
If you had a choice between them, what did you pick and why?
Does your dedicated server provider give it to you for free, or do you have to pay extra for it?
Any experiences with Supermicro IPMI Card - (AOC-IPMI20-E)? I need basic Power managment like APC reboot ports.
Since its very likely that we will get some Supermicro servers, I thought why not add the IPMI card.
My customer has an external facing Apache server that is acting as a reverse proxy to two internal applications. They have:
- external addresses for each app which resolve to different ip addresses, so app1.their_domain.com and app2.their_domain.com resolve to 77.3.170.10 and 77.3.170.11 respectively.
- the Apache server has two network interfaces with ip addresses 192.168.10.10 and 192.168.10.11
- the external ip addresses resolve to the above internal addresses
- the firewall between the Apache server and the internal app servers is configured to allow traffic from 192.168.10.10 to reach app_server1, and traffic from 192.168.10.11 to reach app_server2, both using port 7777.
I have configured a virtual host in httpd.conf for each ip, i.e.
Code:
<VirtualHost 192.168.10.10:80>
...
ProxyPass /app http://app_server1:7777/app
ProxyPassReverse /app http://app_server1:7777/app
RewriteRule ^/$ /app/app1 [R,L]
...
<VirtualHost>
and
Code:
<VirtualHost 192.168.10.11:80>
...
ProxyPass /app http://app_server2:7777/app
ProxyPassReverse /app http://app_server2:7777/app
RewriteRule ^/$ /app/app2 [R,L]
...
<VirtualHost>
This works fine in that the external address are being routed to the correct application, however the firewall is blocking requests to the second app as it appears the requests are coming from the Apache servers 'primary' ip address 192.168.10.10 instead of 192.168.10.11.
Is it possible to send requests using the ip address from the relevant VirtualHost?

I am using virtuozzo firewall to secure access.
I enter 58.27.175.211/255.255.255.0 for Source Address and Netmask for port 22.
But still I can connect using 58.181.103.217 or 58.27.151.120.
Second is it possible to enter two different ip address in source address?
I just bought a new ip address and want to setup this new ip as my server's main ip, making the 'existing main ip' as the secondary ip.
Which means, this new ip will be the server's default ip address for all services, including when connecting to other server.
I'm using CentOs 4.5 and swsoft's panels: HSPcomplete & Virtuozzo Power Panel, and Webmin.
I want to redirect a website to a particular URL so that the address bar shows the same URL and not the destination URL. I know it is possible via URL masking, however, I want it in such a way that whenever somebody clicks on any link in the website, the address bar should still show the original URL. To put it in simple words, Suppose I want to redirect [url] to [url]. Now if there is a link named contact/index.htm and somebody clicks on it the address bar should display [url]and not redirect to [url]
How can it be possible using URL Rewrite method in .htaccess file?
The problem usually goes like this:
- I can't access the webserver
- I'll try to restart httpd, and I'll get
Starting httpd: (98)Address already in use: make_sock: could not bind to address [::]:443
To fix this, I run
[root@www1 ~]# lsof -i tcp:443
COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME
perl 11307 apache 4u IPv6 476943447 TCP *:https (LISTEN)
There is always leftover process that is causing the restart to fail. Once i force kill the process, I am able to restart httpd properly.
Now it is ok if this just occurs once in a while, but this problem keeps repeating itself almost everyday at 4am server time (cron time?). What can I do to permanently fix this?
I recently got my hands on a few unmanaged VPS to play around with and learn how to work on them (eventually plan on going dedicated, so this is a preparation for that). I know the basics of working on Linux via command line, but beyond that I'm clueless. Does anyone know of any good guides for setting up and managing a LAMP environment on a VPS?
I'm mostly interested in CentOS and Debian.
I can find guides specifically for 1 or 2 things, but so far the only useful (complete) guide I've found is the one here. I'm not sure if that's still up to date on todays standards as it was written 2 years ago?
Things I'm looking for:
- Installing and setting up a LAMP environment
- Jailing SSH
- User/Group management
- Firewall setup / security hardening (I've read the thread in VPS tutorials as well as the one in Technical and Security Tutorials about securing your hosting company)
2 more questions...
1) Wondering what would be better... webmin or ispconfig? From what I understand webmin is more OS oriented and allows easy configuration of various parts of the OS while ispconfig is more hosting oriented? I take it running both at the same time is not recommended/needed?
2) Still not entirely sure what OS to choose. In my VPS atm I have the following available (along with the likes of Ubuntu, Gentoo and SuSE but I think the list bellow is what I should use). Would love if someone could list some advantages/disadvantages of each.
- centos-5-i386-afull
- centos-5-i386-hostinabox571
- debian-3.1-i386-minimal
- debian-4.0-i386-minimal
Appreciate any input.
Thanks for reading.
any VPS with management provided?
