[07:14] <netritious> Hi, I'm currently in the middle of an apt-get upgrade and being prompted to select a disk to install grub to since the disk that grub was originally installed to is unavailable. I would like to stop the upgrade and insert the disk that has grub installed and used to boot the system, then restart the upgrade process. I'm assuming CTRL+Z, insert and mount disk, restart apt-get? Is there a safer way?
[07:21] <patdk-lap> your method wouldn't work
[07:22] <patdk-lap> ctrl-z is send to background, not quit
[07:47] <netritious> patdk-lap: I just killed the dpkg process/sub-processes (not with CTRL+C -- you are right, that didn't work), inserted and mounted disk, and ran sudo dpkg --configure -a ... came back with no errors.
[07:48] <netritious> How do I verify the version of grub installed on the device?
[07:55] <netritious> I found it... grub-install -v . Apologies for the rookie questions. It's very early morning here and I'm usually asleep by now. Happy Holidays!
[12:41] <krababbel> Hi, I want to create an LDAP server for central user management and a separate NFS server for serving home directories. I usually see tutorial about having the NFS server on the same machine as the LDAP server. In my case, should I simply setup the NFS server as an LDAP client (for auth), or are there some other issues to know about_
[12:42] <bekks> krababbel: If you want authentication for NFS, you have to use NFSv4, and technically it doesnt matter where the NFS server is running then.
[12:43] <krababbel> bekks: Does this mean, I'd need Kerberos as well please?
[12:44] <bekks> krababbel: Yes.
[12:44] <krababbel> bekks: I see, thank you very much.
[12:49] <LeMike> hello. is it possible to have only access to the ssh root via a certain network while all other user can login as they like?
[12:53] <RoyK> LeMike: see Match in the sshd_config manual
[12:54] <RoyK> LeMike: found some info here http://blog.dhampir.no/content/ssh-how-to-permit-root-login-only-from-local-network-ip
[12:54] <LeMike> thanks RoyK ! :)
[12:54] <TJ-> LeMike: See sshd_config's "AllowUsers" and "DenyUsers", specifically the form "AllowUsers root@remote-hostname-or-IP"
[12:57] <TJ-> LeMike: You can also use "AllowHosts" if you want a global restriction
[12:59] <LeMike> I want only one network to allow logging in as root. I guess AllowUsers might do.
[13:00] <LeMike> thanks :)
[19:35] <hadifarnoud> when I use ssh tunnel, I get errors like this after a while. channel 27: open failed: administratively prohibited: open failed
[19:35] <hadifarnoud> I used root account btw
[19:36] <holstein> !root
[19:42] <TheLordOfTime> hadifarn_: don't try and tunnel over the root acount
[19:43] <TheLordOfTime> that will usually run into problems.
[19:43] <hadifarn_> TheLordOfTime: I was trying to see if errors go away
[19:43] <TheLordOfTime> as holstein said:
[19:43] <TheLordOfTime> !root
[19:43] <hadifarn_> I get same errors regardless TheLordOfTime
[19:43] <holstein> i was thinking maybe its not really ubuntu.. maybe its a spin by a provider
[19:43] <TheLordOfTime> could be
[19:44] <hadifarn_> well, I have two providers. Linode and Rackspace. both are the same.
[19:44] <hadifarn_> this is my ssh command : ssh -C -D 8080 user@domain.com
[19:46] <hadifarn_> I don't understand what that error even means. channel 27: open failed: administratively prohibited: open failed
[19:46] <holstein> hadifarn_: i would try as a normal user with no or less flags
[19:46] <hadifarn_> holstein: you mean no -C then?
[19:47] <holstein> hadifarn_: dropping -C should be easy enough
[19:47] <hadifarn_> will give it a shot.
[19:47] <holstein> hadifarn_: did you enable a root account?
[19:47] <hadifarn_> holstein: yeah.
[19:47] <hadifarn_> even tried with root accont holstein
[19:48] <holstein> hadifarn_: i havent used a root account like that.. only as normal user from stock machines that i have installed to
[19:49] <esde> I'd like to setup SSD Caching with a 60GB SSD and 1TB HDD, then install Ubuntu Server 12.04. I found this guide http://askubuntu.com/questions/252140/how-do-i-install-and-use-flashcache-bcache-to-cache-hdd-to-ssd/314464#314464 to set up bcache, but I do not understand the caveat at the end of the user's steps
[19:49] <esde> *flashcache
[19:50] <holstein> esde: the installation of grub is what is mentioned there
[19:50] <holstein> manually dealing with that should be easy compared to the rest of it
[19:51] <esde> ok, so dont worry until it's setup, then work on resolving that issue?
[19:52] <holstein> esde: thats the way i read it.. but, i might personally prefer trying to covert a system that i have backed up or dont care if it gets messed up
[19:52] <esde> thank you
