...CentOS 6.7 servers, with SuperMicro X8DTE-F motherboards, these have 2 each Intel 82574L ethernet ports. The eth0 ports are plugged in with 10' runs of brand new cat 5e cable to a Cisco Nexxus 9000 switch (provided by the data center). These servers keep coming up at 100baseT rather than gigE. I've swapped ports and cables with a different server, that server gets gigE but these supermicro's are stuck at 100baseT regardless of the port or cableused. 'ethtool eth0' says its gigE, but 'mii-tool -v eth0' says its 100baseT and doesn't even list gigE as an o...

Hi there, When Lustre is configured in an environment where there are multiple paths to the same destination of the same length (i.e. two paths, each one hop away), which path(s) will be used for sending and receiving data? I have my cluster configured with two OSTs with two GigE NICs in each. I am seeing identical performance metrics when I use LACP to aggregate, and when I use two separate network addresses to connect them (ditto on the client side). So what I''m wondering is if I''ve hit the peak performance of my disk array, or if Lustre is just using o...

I have a beefy machine (Intel dual-quad core, 16GB memory 2 x GigE) I have loaded RHEL5.1-xen on the hardware and have created two logical systems: 4 cpus, 7.5 GB memory 1 x Gige Following RHEL guidelines, I have it set up so that eth0->xenbr0 and eth1->xenbr1 Each of the two RHEL5.1 guests uses one of the interfaces and this is verified at the switch by s...

...n/ifconfig /sbin/ipmaddr /sbin/iptunnel /sbin/mii-diag /sbin/mii-tool /sbin/nameif /sbin/plipconfig /sbin/route /sbin/slattach ok, so the mii-* stuff is deprecated (as is route, ifconfig, netstat, and arp? sigh). apparently the network administrator went ahead and forced the switch port to use gigE, so its no longer in the 'broken' state of autonegotiating 100baseT. -- john r pierce, recycling bits in santa cruz

I have a samba server with 2 ethernet ports, one of which is a gigabit port. When connecting from a windows client that has a crossover to the gigabit port, and a crossover to the 100Meg port: If I connect via \\gige.ethernet.address\foo , and copying a large file, windows reports outbound traffic on the gige port and return traffic on the 100Meg port. Thus, it seems the samba server sees the client->server traffic via gige but is responding via the slower interface. Not what I want. Any clues? Thanks, A...

BUT... the switch ports kept going offline on us. Note I have no admin access to the switch, its managed by IT so I have to go through channels to get anything. I asked what error codes were causing...

Folks, I realize this is off topic, and if anyone can suggest a better source for the question, I'd be glad to go there. Novell SUSE's support is unresponsive, however. My problem is this: I'm running 9.3 Pro on an Intel server board that has two NIC chips built in (a 10/100 and a GigE). I've since added a Netgear GigE NIC. However, every time I reboot, the NICs assigned to eth0, 1, and 2 all change at random, as do the IP addresses assigned. This happens whether I do anything at all or try to set things up through YaST. I'm trying to set up two subnets off this...

Hi all, I've recently upgraded a system from CentOS 4.4 to CentOS5, and now when the system boots, the r8169 ethernet card doesn't come up. After the boot sequence, if I type "ifup eth1 | ifup eth1.10 | ifup eth1.203" then the adapter starts up ok. It seems to be something with the boot sequence it loads the ethernet adapters a different way around (ie 4.4 eth0 is now

GigE wasn''t giving me the performance I had hoped for so I spring for some 10Gbe cards. So what am I doing wrong. My setup is a Dell 2950 without a raid controller, just a SAS6 card. The setup is as such : mirror rpool (boot) SAS 10K raidz SSD 467 GB on 3 Samsung 256 MLC SSD (220MB/s ea...

Hi folks :-) situation: debian stable (samba version 2:3.2.5-4lenny9) from clients by ftp the transfer of huge file is about 10/11Mb/s (with an ethernet 10/100) by samba came 5/6Mb/s is it correct? In smb.conf I don't have any "strange"options: thanks Pol domain master = yes preferred master = yes os level = 65 workgroup = WORKGROUP netbios name = name Server String = name

Hi, I'm a happy Samba user. I've been working sucessfully in Linux for the past 6 months. I've built a Linux Server with very fast storage and I'm connecting it to many Windows XP "video editing workstations" via Gigabit Ethernet (all NICs using Jumbo Frames, by the way). Now I want to see if I can increase my data flow in and out of the Server so that more

I'm running a server recently installed with centos 4.2. It's running the kernel in the subject line, on an PIII 866Mhz with 512mb ram. The system is running basically two processes: 1) ssh to remote system, receiving a stream of bytes piped into 2) gzip the stream, write to disk file The system is slow, relatively (866Mhz cpu) and the network is fast (gigabit) so the limiting factor

Folks, I'm trying to add a network interface card to my SUSE 9.3 box, and I'm not having much luck with a US Robotics version. What manufacturer do any of you use in your machines--either 10/100MB or GigE NIC?
