I'm preparing to install RHEL 7 on my server. I read in doc that

The networking teaming daemon, teamd, is not installed by default.
To install teamd, issue the following command as root:
yum install teamd

By default my server is not internet-connected. Internet is available only via certain VLAN over LACP, so I have to configure teaming without internet.

  • Is it correct that by default RHEL 7 doesn't have teamd?
  • If so how can I install teamd without internet?

upd I also noticed that on CentOS LiveCD teamd IS installed by default. So I wonder what documentation means by "teamd, is not installed by default". Do they mean "minimal install" only? If I install "Server with GUI" will I have "teamd"?

upd2 It's more a research question. I don't have working RHEL 7 environment right now to verify. If RHEL 7 has preinstalled teamd then I think the only question I have is why doc says that it is not.

  • The documentation likely is referring to that the RPMs are included with the media but are not installed. That's not an issue since you can mount the CD or the ISO on the system to retrieve the RPMs on the offline server when they're needed. – slm Oct 08 '14 at 20:53
  • thanks, I guess this should work! So I should do something like this http://fritshoogland.wordpress.com/2012/05/26/using-your-dvd-as-a-yum-repository-on-a-rpm-based-linux/ – Oleg Vazhnev Oct 08 '14 at 21:05
  • Yes you can do that or put the ISO on the system when you build it and then mount it when needed: mount -o loop rhel.iso /mnt and then do yum local installs from that the media. – slm Oct 08 '14 at 21:11

I don't think that you need this unless you're planning on teaming multiple network cards together as one.

excerpt - http://fedoraproject.org/wiki/Features/TeamDriver

The purpose of the Team driver is to provide a mechanism to team multiple NICs (ports) into one logical one (teamdev) at L2 layer. The process is called "channel bonding", "Ethernet bonding", "channel teaming", "link aggregation", etc. This is already implemented in the Linux kernel by the bonding driver.

One thing to note is that Team driver project does try to provide the similar functionality as the bonding driver, however architecturally it is quite different from bonding driver. Team driver is modular, userspace driven, very lean and efficient, and it does have some distinct advantages over bonding. The way Team is configured differs dramatically from the way bonding is.

This feature consists of two parts:

  • kernel module (modules). They are already part of Fedora 18 kernel package.
  • userspace library (libteam package) and daemon (teamd package).

Although there is support for Team driver in initscripts, the plan is to integrate Team devices handling into Network Manager as well, probably for Fedora 19.

For downloading online you should be able to make use of the methods I describe in this U&L Q&A titled: How to download a file from repo, and install it later w/o internet connection?.

  • that's right I need to teem 2 network cards (LACP) and to add special VLAN to have Internet access – Oleg Vazhnev Oct 08 '14 at 20:38
  • Ah then you'll need to install this software prior. Hang on I'll get the command to download the s/w. – slm Oct 08 '14 at 20:40
  • i can't even activate RHEL 7 so probably many commands will not work. I'm newbie to RHEL 7. I can't verify now if teamd is preinstalled. I guess it must be preinstalled, because CentOS livecd has it. But why documentation says that it is not preinstalled? – Oleg Vazhnev Oct 08 '14 at 20:44
  • Do a rpm -qa | grep teamd – slm Oct 08 '14 at 20:45
  • unfortunately i can't do anything right now. currently I have Windows only. I can experement on weekend only, because from monday to friday i can not reboot my Windows server. Next weekend I plan to try to setup dualboot RHEL 7 / Windows again. Now I just researching how to make it better, what should I do etc. because I have weekends only. I want to prepare. this weekand my girlfriend has a birthday and next weekand I have to visit my grandfather, so I don't have to much time and I researching now :) – Oleg Vazhnev Oct 08 '14 at 20:49
  • @javapowered - no problem, we'll be here when you're ready to proceed. – slm Oct 08 '14 at 20:52
  • I hope I will be able to verify that on Saturday, but if I will not be able to "tune" Linux for dual-boot Linux/Windows I have to clean everything and reinstall Windows once again. That's why I'm trying to prepare. So trying to understand IF teamd is not there and I don't have Internet - what should I do? Hmmm, alternatively, I can try to install RHEL 7 on some machine at home just to verify if teamd is there... – Oleg Vazhnev Oct 08 '14 at 21:00
  • @javapowered - I'd install it on a Virtualbox VM to confirm. You can scan the RPM directory of the CD/DVD to see if the RPM's there too. – slm Oct 08 '14 at 21:03
