I am trying to setup a blade server that has a QLOGIC 4062 mezzanine card to handle the iscsi traffic coming from an HP MSA 2312i SAN. I cannot seem to figure out how to get the HBA to talk to the SAN. Just to ensure the SAN was setup OK, I used the onboard netextreme NIC w/iSCSI to connect to the SAN with iscsiadm. This all works no problem. BUT, I bought the mezzanine cards to take this load of my NICs.
I know that the OS sees the two ports on the mezzanine card as dmesg shows them. This is my first time configuring a separate HBA on a blade system, so I'm kinda lost what to do with them. I have entries in the modprobe.conf file for eth2 and eth3 aliased to qla4xxx. What I am not sure about is the config for each eth2/3 device. If I ifconfig my device to the specific ip and subnet/netmask my SAN is on, I can get any response from the SAN.
Also I would have expected iscsiadm -m iface to pick up on the qlogic devices, but they don't show up in the ifaces directory. I tried to manually create an iface file for each, and it seems to be ok with that, but when I try to discover targets, I get communication errors. (I am compiling a file with all the outputs from various commands and errors, and will put them here once I have them).
What I don't understand is the process of setting up an HBA. I am quite able to setup iscsi over the regular NICs, been doing that for a while, but these HBAs have me stumped.
I also installed the qlogic qla4xxx driver and SANSurfer, but SANsurfer didn't see the HBAs. I think this was due to the age of the sansurfer software...other people have reported this as well.
We had a problem with the NIC 10Gig Qlogic NICs and had to swap them with Emulex 10Gig NIC cards. The swap has been done. There are several severs (about 100)for which we need to check if the hands-on still left the q logic card in them. So, I wrote a script using dmesg and grepped for "qlogic" or " NC522SFp" and my script checked for all the servers and returned no presence of "qlogic". But few of them have q logic still in them. So, is there any other way through which we can exactly tell whether q logic card is still present or not? I used:
and found nothing in the o/p. But when I checked using ifconfig -a, then I see the q logic mac ids for eth4 & eth5, which means the Q logic is still present.But not sure whether ifconfig is the real way to find out the presence of these cards.
We have a SuSE/SLES 9 server that boots from a fibre channel card, using volumes from a NetApp filer.
We previously had the server booting from the LUNs on the filer, but after some tinkering around with the fibre channel BIOS, we have the situation where the LUNS seem to be mounted, the OS boots, starts to initialise everything but then stalls, saying:
We have tried loads of combinations of settings in the BIOS and fibre channel BIOS without any success or any idea what may have caused the error.
I'm trying to find out when QME2572 (Qlogic) card became support by the kernel. We have a RHEL 5.1 system that is moving to new hardware, however the kernel at this release doesn't support the new hardware, due to the Qlogic card change. I tired the Redhat KB and Bugzilla. Is there a Kernel change list etc I can search. Never really played around with the kernel too much so I'm just after some pointers for looking up this information. Offically its not supported until Redhat 5.3, I'm trying trying to research kernel info so I can tell the customer they have to upgrade.
A group I'm working with recently got new netbooks with Ubuntu Netbook Edition 10.04 and some AT&T LaptopConnect (3G) cards. When I hook them into the usb port, the cards light begins blinking, but nothing shows up to indicate ubuntu has recognized the new card, nor am I able to connect to the internet. My searches for help have indicated no one else has had any difficulty with this and that the card usually pops up and installs some drivers automatically or something.
I'm not sure at the moment the model of the 3G card other than very new, but I can check on that in a bit. The netbooks are HP Mini 210s.
Recently I hibernated my computer, then when starting up again managed to boot into Windows instead. When I rebooted back into Ubuntu 10.04 my network card had stopped connecting to the internet.'s not a problem with my connection -- I'm posting this form Windows just fine. Using the network tools tool I can see that the card is inactive.I can use ifconfog to reactivate it, but it still won't connect.Attached is as many commands as I could find that provide information about the card
So I bought a used Dell Precision 390 Workstation and installed Ubuntu 9.04 on it. Everything seems to work fine, except for the built-in network card. Well, the graphics don't really work right, either, but I rather expected that, and I'll get to it later.
Anyway, when I boot Ubuntu and try to get on the internet, it says I'm not connected. When I open Network Tools, in the "Devices" tab, I get three Network device options: Loopback Interface, Ethernet Interface (eth0), and Unknown Interface (pan0). When I click on the ethernet device option, it shows me the hardware address of the interface, that it has multicast enabled, and that it is "Active", but I get no IP address.
Is there something really stupid that I'm missing? Do I need to do something special the first time I hook up an ethernet cable? I don't seem to remember having to do that on other Ubuntu boxes.
I have recently installed Ubuntu 10.04, and today the wireless connection has started to become spotty. The networks menu shows no wireless entries when they were there the day before. Again I have the Atheros AR5001 wireless card, my network is WPA2 and is 802.11g
I have a CentOS server that I can connect to over my local network. The computer I'm currently on is on that same network and can access the internet. My server can not connect to the internet. The network card is obviously connecting to the network since I can access the server locally with SSH or HTTP. While in the terminal for the server, I type wget google.com and the server can not find the specified host, so this leaves me to believe it can not access the internet.
I want to use centos as a developer server on my desktop before deploying my stuff to the internet.
I have a netgear DG834G router. It's IP address on my local network is 192.168.0.1 and connected to the adsl line. The router is set up to act as an dhcp server too. On the router I have reserved ip address for the nics per their mac addresses.
My server is on a dual boot desktop. The other boot is XP and works fine, picks up dhcp.
I don't know how to connect Centos to the router.
I have tried to play with the network manager but to no avail.
I can ping localhost, interface eth0 is there, but i can't ping to the router.
I have set the manager system/administration/network to get dhcp automatically.
I can't activate the eth0 although the hardware device says it is OK.
I am a newcommer to Centos. I should connect to internet via a pptp vpn connection. I created the connection in "network connections". In other distrows I could connect to created pptp vpn connection simply by clicking on network-manager-applet and selecting the connection, but there is no network-manager-applet in Centos. Is there any way to connect to the vpn connection I created or I should go to do it by manually editing config files?
it is possible to have the following network configuration: a central location called A with an ISP and two more locations (let's call them B and C) with diferent ISPs and to have a vpn connection between A and B and A and C? More exactly I have a central location with a CentOS 5.3 running as a gateway and I want to know if it's possible to have a computer from the location B and C connected to A through a VPN connection. I don't want computer from B to see the computer from C, is not necessary. What kind of equipment do I have to put in places? Routers? Managed switches? As a start I think that it have to work with a router in location B and one in location C and in location A I think that a managed switch that can manage vpns it will be ok.
I recently downloaded and installed CentOS 5.3 DVD media.The media check passed. I proceed to install the operating system sucessfully. After installation, all my hardware is recognized, when compared to CentOS 5.2. Anyway, when I attempt to connect to my wireless network that uses either WEP/WPA/WPA2-- I get an error message that I cannot recall (it basically only came up when I entered the key) However, I can connect to my wireless network when it is unencrypted and no open/shared key is needed.I would like to be able to connect to my wireless network when
FYI: I am using a RealTek RTL8185 Wireless Driver.Also, I use CentOS as a workstation.
When running Firefox, page loading is very slow (e.g. taking nearly a minute for a ..... video to start; even gmail is slow). This is in contrast with my performance when using, e.g. linuxdcpp (file sharing), where I get speeds over 300kbps. Here is some relevant information:
I've installed from the CD the Centos version 5.5. When I try to connect to Internet I can't because I received some errors. I've the Intel Corporation 82801CAM (ICH3) PRO/100 VE (LOM) Ethernet Controller also a wireless slot (I've the wireless card DWL-G650+) When I turn on the pc and I go to "Ethernet Device", I see set: peth0 (Intel Corporation 82801CAM (ICH3) PRO/100 VE (LOM) ETHERNET CONTROLLER) and also set "Bind to MAC address": fe:ff:ff:ff:ff:ff I've set manually the IP address (I'm under router). Status is "Active" but can't go on the Net. When I change to "eth0 (Intel EtherExpress/100 driver)...sometimes become "Active" an other times said that the MAC address is different or to check the cable because can't find the IP. What can I do?
I am using asus p5ld2-x/1333 motherboard,I installed the centos ,Centos saw other drivers but didn't see ethernet card.I am not connection the internet.
I just upgraded from Ubuntu 9.04 64-bit, to CentOS 5.5 64-bit and my RT-73 USB network card doesn't seem to want to function. It always worked fine in Ubuntu by default (plug and play). Is there some setting I need to make to get this working?Even BT-3 (which is quite old) recognizes the RT-73.
I'm having a bizarre problem with FTP transfers from my CentOS 5.3 boxes, All of my CentOS boxes appear to be limited at ~10kb/s when connecting to any FTP server outside of our network. We have no network infrastructure which would cause this, however when I use a windows based machine it is able to connect fine.
I took my laptop running Vista, and rebooted it onto a CentOS 5.3 LiveCD, and same issue.
I have checked our iptables, cleared the rules, removed the kernel modules, checked CBQ/TC it looks like nothing is limiting this. Also, other protocols work fine. Both the windows and linux boxes used passive transfers for it.
Is there anything other than iptables/CBQ which would be on a out of the box install of CentOS I should check? Is there any kernel settings for NAT connections which may cause this?
I installed CentOS 5.3 on my Shuttle SS-31T with SiS 190 network adapter. While booting the message "Bringing up eth 0 [ OK ]" appears. After booting it isn't possible to surf to an internet location (p.a. www.google.com). It's also impossible to ping other machines in the network. After typing ifconfig everything seems to be ok.
ipv6 is turned off IP : 192.168.0.3 Subnet : 255.255.255.0 Gateway : 192.168.0.1
I have a Centos 5 server on my LAN for testing the websites that i develop.It worked perfectly until this morning , after cold start -up, it seems that my network card is not enabled . Everything works normal:gui and terminal but no internet access. I'll run some commands on my Linux box and write the results , by hand , to this forum .

I just installed Ubuntu 9.10 and its great. However when I connect to the internet at home it shows that the connection has been established but I still cant connect to the internet. My flatmates are all able to connect. However, I am able to connect from work both wirelessly and through an ethernet cable.
i did configure as it was advised on [URL]... but it didn't work. for eg I added eth0:1 and eth0:2 on /etc/sysconfig/network-scripts/ when i do ifconfig i can see only eth0:1, i cannot see eth0:2, eventhough i configured as it was on the tutorial
i have installed centos 5.1 but it won't recognize 2nd nic card (eth1). i was unable to install the driver supplied by the cd. i am using intellinet gigabite pci network card. the network card recognize by centos 5.3 but i need to use centos 5.1. i also tried another intel gigabite adopter but it also won't recognize by centos 5.1.
I have a ESXi 4.1 build 433742 server with a CentOS 5.4 virtual machine.I installed VMware Tools.I added a vmxnet3 network card on virtual machine for 10GbpsBut my problem, the card doesn't UP ! the resultat of my commands :
[root@centos1 ~]# ifconfig lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0
I am looking for a gigabit network card for my centos 5.4 server. I am looking for something known to work well with linux. I have been on the bestbuy site and I found a DLink (DGE-530T) card with support for linux from the vendor but after reading feedback from users with that card I am not so sure it is linux friendly. I am now thinking of buying online.
I have a problem to configure my wifi card, a dwa-110 from D-Link, it is not recognized when I launch System / network device control (only ethernet connections appear), and it is the same thing in Administration / network / network configuration. But if I launch administration / hardware / system devices, the last line is "Ralink 802.11 bg WLAN"... When I try to add in the window "network configuration" (from above) some new stuff, I specifying the kind of hardware (wireless) and when I have to enter the name of the card I don't see my card. On other OSes, I used ndiswrapper, but I wasn't able to install it on CentOS (dependencies required and it's hard with only a USB key to install the stuff...) How to see if the card is recognized, if I have to use ndiswrapper and so on. I have an internal PCI network card also, maybe it is this card which is recognized.
