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?
I 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.
We have 2 Cisco PIX 515's in a failover configuration (7.1 series IOS). We have available both a serial failover cable and adequate switch capacity to allow using either the serial or LAN-based approach. We have no current plans to locate the firewalls physically apart.
We have plenty of info on how to configure either, but no recommendation on which is the better choice.
SOA Serial
SOA REFRESH
SOA RETRY
SOA EXPIRE
SOA MINIMUM TTL
This are all items of DNS and by default set that :
SOA Serial= 0
PassSOA REFRESH= 10800. That is OK
PassSOA RETRY = 3600. Looks ok
PassSOA EXPIRE = 604800.Looks ok
PassSOA MINIMUM TTL= 10800 is OK (RFC2308 recommends a value of 1-3 hours)
SOA Serial always is set to 0 and this is a wrong setting.
I got my hands on a used 2161DS (unit only, no cables etc), but somehow it doesnt seem to respond on the hyperterminal to any keyboard input.
As its used it doesnt have any support directly from Dell and Dell is unable even to give us a cost estimate as the service tag number is not in their system. Anyway...
When I power up the 2161DS KVM-Over-IP switch all I get in the Hyperterminal is
---
Verifying subsystem flash versions...
<snip>
DELL 2161DS Console Ready...
Press any key to continue
---
From there on its not working. The keyboard and mouse directly connected to it are working. Also all the menus, but we can set the network address, do firmware updates etc, only from the serial port connection (once the serial port is working).
I checked the hyperterminal settings (9600 baud, 8 bit, 1 stop bit, no parity, no flow control).
Is there anything that I might be missing?
Perhaps I have to use something like a crossed serial cable instead of a straight one ?
Character set issues?
Terminal type issues?
We have spent days in front of the machine and on the phone with Dell without really getting anywhere. Its our first 2161DS so I still want to believe that we must be missing something.
I have one domain (just one?) that has a serial of 0 (on my server 5.9.57.170 , latest plesk)
Because of that, dns updates don't happen, dns servers don't respond , and my domain issuer is threatening to revoke the domain as it is not working as it should.

robotns3.second-ns.com. torsten.ruger.gmail.com. 0 10800 3600 604800 10800
You can see the test here [URL] .... when you enter the domain auringostaitaan.fi
In trying to fix this i have switched the dns off,changed the mode, enabled RIPE, but i get what it says [URL] ....
Note: See the sample of SOA serial number generated with the selected format. If the resulting number is less, than the current zone number, the modification may cause temporary malfunction of DNS for this domain. Zone updates may be invisible to Internet users for some time.
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?
there are many online tools to check the health of our servers, domains, smtp services, etc.
this came to my attention a long time ago, but it is now that i actually want to try and fix this stuff.

Say a server has 2 gig-e ports on board, and the OS
is using both. Can I still use IPMI feature? Or do I have
to get an additional ethernet card?
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 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 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 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:

This server has on the IPMI shared port the address 10.0.1.2 ...
When I try to ping the IPMI board from the server itself or from a different server I get an incomplete address in the ARP table;

(Also after pinging it for 1 minute...)
If I use the IPMI utilities I am unable to contact the board and do anything with the server....
I tried several settings of the IPMI board, including DHCP / ARP on and off...
Does anyone have this combination working, and how did you do this?
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 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
I've noticed on some rackmount servers and firewall appliances there are ports labelled console, and look like serial ports. Are these related to connecting to KVM? I am looking for a cheap appliance for some rackmount servers I have (1U half depth would be ideal), to remotely recover the server if it goes down. I figured they'd connect through PS2 connectors, but then I thought that if the console port was related, then going through that might have the option for power cycling or something.
View 7 Replies View RelatedI'm trying to knock a bug out of our new Hardy Heron Xen template. Basically when the old ones boot up /bin/sh is spawned on the console. Now with Hardy init has been replace with /etc/event.d handling.
So I've replace /etc/event.d/ttyS0 and ttyS1 (not sure which one is the console but I think ttyS0)
Code:
# tty0 - shell
# This service maintains a getty on tty1 from the point the system is

I am upgrading my current colo'd server from a 1U dual core xeon with 2x500GB drives to a 2U core 2 quad with 8x750GB drives (raid5).So far I have ran into two issues. One is the rails are too large for the cabinets (problem #1 which I put in another thread). The only other problem is I am having problems with remote console on the new hardware.
It should be setup correctly since I basically rsync'd everything from the old server to the new one. The device is detected:
root@houkouonchi: 03:19 AM :~# dmesg | grep -i tty
Command line: root=/dev/sda2 gpt pci=nomsi console=tty0 console=ttyS0,9600 notsc
Kernel command line: root=/dev/sda2 gpt pci=nomsi console=tty0 console=ttyS0,9600 notsc
console [tty0] enabled
console [ttyS0] enabled
serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
00:05: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
But when I connect to the digi I am not getting any console output. I have tried a different serial -> Ethernet adapter and tried a different patch cable/port on the digi so I am pretty sure those are fine. The motherboard (nforce 650i chipset) didn't have an onboard serial port so I am using a port hooked up to a bracket which has a ribbon cable which connects to the motherboards COM port. I also tested another serial connector which the case has built in and both give me problems.
Maybe the motherboard is just busted?
How can change hypervm console user for a vps?

im trying to remotely install WS2003 EE R2 on a dedicated server I have purchased and have an issue. I'm installing it via KVM IP which is cool
however, after installing the network card drivers, I get a "There is no or limited connectivity" etc... so I cannot access the internet or anything on that box.
what do I do from here? how can I make the card work? It is configured to obtain the IP Address automatically as well as using the default DNS. I do have 2 IP Addresses "assigned" to me/my account but dont believe I need to configure them in WS2003?
Is it better to have a rack in a carrier neutral datacenter and get feeds to the rack from various diverse carriers.
Or
Is it better to have a rack in an ISP datacenter where they provide the connectivity for you?
is anyone else having trouble with burst.net at the moment? from two locations, i'm having problems where anything that will elicit a large response just hangs indefinitely. i can ping my server just fine, i can shell into it... if i do "top" or "dmesg" or anything else that might dump back more than a few lines of response at a time, the ssh session hangs. i can do "ps x" as a regular user, because i only have two processes running. "ps ax" will hang ssh.
none of my websites work, and i can't get on the burst.net website from either location. i tried calling but no matter what sequence i try for (even tried reboots) i can't get ahold of a live person, but then again it is almost midnight.
anyone else experiencing this?
I have tested so many compagny I can't even remember and with all of thoses compagny my customers had lagg pikes or this kind of things.
I am hosting a gameserver service which required a top connectivity , most of my customers are in europe and I looked for the best dedicated provider in europe.
I tested OVH , ngz-server , bestserver.eu and much more but it was the same problem.
If someone know a good dedicated server provider in europe using premium bandwidth with good carier and not only with peerings .
I have looked a bit at serverboost.nl they seems serious but I have no feedback about them.
If you have any provider with a top connectivity it would help me a lot to choose what deserve my customers.
A DDos protection is a must also (not for bigg ddos but littles one ).
What type of cable/settings are needed to access the console port of a ProCurve 2626 J4900A? the recent one I ordered wasnt working with the regular way I access these switches.
I use a null modem (crossover) female-female serial console cable and connect it to my laptop serial port w/9600-8-1-None to access my ProCurve 2900 48G series.
But I tried using a straight/null/rollover(cisco's) and none of them worked. I also tried 9800-8-1-xoff/xon. All of them are giving me weird text when I press [ENTER] numerous times. I can access my 2900 series switches fine, no problem, just these 2626 ones I cant. My laptop can definitely detect the port cause when I disable it, I get a message on my terminal window which says "disconnected". So I am messing up somewhere.
By the way, I actually returned the switch when it came the first time because I thought they gave me a faulty one and I got another one, but it behaves the same way. But the actual switch functionality has no issues as I can assign my servers IPs and be able to access them remotely. I just cant configure the switch itself without the console port.
