Hi *, I'm running into a problem configuring bonding on an HP DL 360 G4p, running 4.3 + tg3 driver version 3.43f. I'm connecting eth0 and eth1 to a Cisco 2948 (CatOS 8.1(3)) and receiving flapping notices. The ethernet address is that of the primary interface. I have tried several different modes, including balance-rr (0), active-backup (1), and balance-alb (6). All have the

I have a few RHEL7 boxes, all of them are members in MS Win domain using SSSD. All of these linuxes run Samba for file sharing with the same config. Usually it works nice, but from time to time users cannot map Samba folders, with the following message in the log: [2017/03/07 14:58:27.050493, 0] ../source3/auth/auth_domain.c:121(connect_to_domain_password_server)

Greetings: I know it's been mentioned before that the tg3 driver in CentOS 3.4 is buggy. I had to revert to 3.4 today from 4 (fresh install) and now I have no link and thus no network. I'm wondering if this is caused by this bug and what the work-around is. Thanks. Brendon Colby

What's the procedure for filing bug reports related to kernel panics on CentOS/RHEL? I've just had the following kernel panic on one of the new mailstores (argh!). Would this have to be reproduceable to warrant a bug report?

Hello, I suggest you start reading here: https://fedorahosted.org/sssd/wiki/Configuring_sssd_with_ad_server and if you want to use winbind and not sssd. read : https://wiki.samba.org/index.php/Setting_up_Samba_as_a_Domain_Member Now i dont use sssd and there is an other mailing list for sssd, ( sssd is not related to samba (yet) but my guesses are.. - your keytab is expiring and not

We have a cluster (212 nodes) that are on a gig-e network useing jumbo frames (mtu 6000) To reload a node we have to plug it into a regular 1500 mtu that is running off a differnt port on the head node to install. Is there a way to tell in the 'append' line of /pxelinux.cfg/default to have the bcm5700 module run wiht jumbo frames. this is our append right now append load_ramdisk=1

Hi Brock, I'm trying set full duplex on a server that is being pxeboot/provisioned via autoyast. We want to ensure the duplex is full DURING the autoyast provisioning itself. I've played the syslinux configs to specify the bcm5600 driver, but was having trouble with setting the network options. I've tryed appending them as well, but nothing on the internet seems to indicate that

I use bonding under CENTOS4.5 x32_62. I have these weird messages when I'm restarting network. Do you have any ideas how to fix this? (there is similar bug for centos5 http://bugs.centos.org/view.php?id=2404, but the author says that it worked for him in centos4...)

Been having this problem, and posted about it before. Thinking it was a memory issue, I've replaced all memory on the server. However, the problem has continued. Server is a Proliant DL380 (8GB RAM, 2 Xeon CPU), running CentOS 3.6, all patches up-to-date. Kernel is 2.4.21-40.ELsmp (problem seems to have first manifested on kernel 2.4.21-37.0.1.ELsmp). Disk is CCISS hardware RAID-5,

I apologize for posting on this question again, but unfortunately, I don't have and can't get access to MASS for at least three weeks. I have found some code on the web however which implements the prediction error algorithm in cv.glm. http://www.bioconductor.org/workshops/NGFN03/modelsel-exercise.pdf Now I've tried to adapt it to my purposes, but since I'm not deeply familiar

We are in the process of migrating XFS filesystems from one storage array to another. Both are arrays are mounted locally on the same CentOS 4.4 system (x86_64). We are running kernel 2.6.9-42.0.2.ELsmp along with kernel-module-xfs-2.6.9-42.0.2.ELsmp-0.1-3. The issue we are having is that while the copy is running (using rsync) the system will log these message periodically: kernel: XFS:
