| mason | So, I see Nehalem and Nehalem-IBRS cooked into qemu-2.11+dfsg/target/i386/cpu.c. | 02:13 |
|---|---|---|
| mason | I wonder if my host is too old to have CPUID_7_0_EDX_SPEC_CTRL or something. I'm not 100% sure how that works as yet. | 02:16 |
| mason | I don't know. I migrate the thing over, and Nehalem-IBRS no longer shows up in the list of possible models, but it does show up as the active CPU model. Weird. | 02:20 |
| mason | Oh well. | 02:20 |
| cpaelzer | mason: those are libvirt specific types | 09:25 |
| cpaelzer | mason: for qemu that is some-base-cpu+feature-bits | 09:26 |
| cpaelzer | libvirt does host probing for capabilities, so maybe due to that it differs | 09:26 |
| cpaelzer | well your question was so many hours ago, did you find anything already? | 09:26 |
| mason | Ooh, here's an opportunity to use the memo-bot! | 13:53 |

| kinghat | why am i now getting "kinghat is not in the sudoers file. This incident will be reported." on my server? | 22:47 |
| kinghat | was there a recent update that changed something? never seen this before except for on fedora. | 22:47 |
| ikonia | kinghat: you have changed either the sudoers file, or you're users group membership | 22:56 |
| kinghat | hmm | 23:01 |
| kinghat | i think i added the user to the group `web-content` for apache, would that have done it? | 23:03 |
| kinghat | i thought the user could be apart of multiple groups? | 23:03 |
| ikonia | kinghat: I suspect you've added the user to the group and at the same time removed it from the admin / wheel group | 23:04 |
| ikonia | yes, a user can be a member of many groups | 23:04 |
| ikonia | type "id" against your user | 23:04 |
| kinghat | uid=1000(kinghat) gid=1000(kinghat) groups=1000(kinghat),1001(web-content) | 23:04 |
| kinghat | ya i was just going looking for the commands to get a table of users and groups on the system. | 23:04 |
| kinghat | ikonia: so you are saying i need to get root, then add my user to `sudo` user group? | 23:09 |
| ikonia | what groups is your user in ? | 23:09 |
| kinghat | because i cant add my account via sudo atm because its not part of sudo. | 23:09 |
| kinghat | i posted it above i thought. | 23:10 |
| ikonia | oh yes | 23:10 |
| ikonia | so boot into single user mode and add your user to the sudo group | 23:10 |
| kinghat | single user mode = root? | 23:10 |
| ikonia | what ? | 23:11 |
| kinghat | what is single user mode? | 23:11 |
| ikonia | it boots the user into just that - single user mode, rather than the multi-user mode and permissions system you currently have | 23:11 |
| ikonia | or you can just become root if you've set a root password and know it | 23:12 |
| kinghat | i feel like ive logged into root using the same password as the initial account before w/o having set an actual root password. | 23:13 |
| ikonia | then su - | 23:14 |
| kinghat | ya i just did that and it says su: Authentication failure. | 23:14 |
| ikonia | then you don't know the password | 23:14 |
| kinghat | if anything i made it the same as the initial account. actually i figured thats what the installer did by default. | 23:15 |
| ikonia | nope | 23:17 |
| ikonia | it does what you tell it to do | 23:17 |
| kinghat | so i have to give root a password before i can use root? | 23:18 |
| ikonia | yes | 23:18 |
| ikonia | (the correct model is to not set a root password and have a sane sudo setup) | 23:18 |
| kinghat | sure but how do i get my only user back to sudo then? | 23:19 |
| ikonia | boot into single user mode | 23:20 |
| kinghat | can that be done via ssh? | 23:20 |
| ikonia | possibly, but it normally requires console access as single user mode is not on the network | 23:20 |
| kinghat | why would adding this user to another group take it out of another group? | 23:22 |
| ikonia | depends how you added it | 23:22 |
| kinghat | sudo adduser username groupname | 23:22 |
| ikonia | kinghat: that's creating a new user | 23:22 |
| ikonia | that's not adding a user to a group | 23:22 |
| kinghat | sorry it was this: `usermod -G web-content alice` | 23:23 |
| kinghat | but `kinghat` over alice. | 23:23 |
| kinghat | and i also added apache to that group. | 23:24 |
| ikonia | so that's just told the system to put the user kinghat in the group web-content only | 23:24 |
| ikonia | that's not adding a user to a group, that's setting a user to that single group | 23:24 |
| kinghat | well that explains it | 23:24 |
| ikonia | I suggest you read the man page of commands if you don't know how to use them | 23:24 |
| kinghat | https://wiki.apache.org/httpd/FileSystemPermissions | 23:25 |
| ikonia | ? | 23:25 |
| ikonia | what has that got to do with anything ? | 23:25 |
| kinghat | i feel like there should be a warning or something. are you sure you want to remove this user from all groups? especially the sudo group. | 23:25 |
| ikonia | no | 23:25 |
| ikonia | you should read the man page of commands you don't know about, more so if executing them with root access | 23:26 |
| ikonia | the man page is really clear on the syntax | 23:26 |
| kinghat | well now i have to figure out how to get single user w/o console access. | 23:26 |
| kinghat | what about giving root a password then doing what i need and then removing the password from root? | 23:27 |
| ikonia | I suspect that will be exceptionally hard | 23:27 |
| ikonia | how do you plan to set a root password without having root access ? | 23:27 |
| kinghat | you mean w/o being apart of the sudo group? ya i was just realizing that. | 23:27 |
| kinghat | fak | 23:28 |
| ikonia | please control the languge | 23:28 |
| kinghat | so basically i cant really do anything w/o having physical access? | 23:29 |
| ikonia | you'll find it exceptionally hard | 23:29 |
| ikonia | and high risk | 23:29 |
| kinghat | apparently im high risk. | 23:30 |
| ikonia | what ? | 23:30 |
| kinghat | im the risk. | 23:31 |
| ikonia | clearly | 23:31 |
| OerHeks | no direct access makes it just a little complicated | 23:31 |
| kinghat | you have to edit grub? | 23:35 |
| ikonia | that is one of the high risk ways, however if you did it right and it boots into single user mode, how will you interact with it ? | 23:36 |
| kinghat | no im asking thats how you get into single user mode? | 23:38 |
| ikonia | right, there are a few options, but what's the plan if you did get it into single userm ode | 23:39 |
| kinghat | you said add my user to `sudo`? | 23:39 |
| ikonia | how will you do that remote | 23:39 |
| kinghat | i dont have physical access atm but i will have to get physical access apparently so. | 23:41 |
| ikonia | so I'd deal with that when you get access as the access you get / how you get it will guide you the best way to get access to the root user | 23:42 |
| kinghat | i mean i have to go there to get physical keyboard/monitor console access. its going to happen once i figure out how its done before i go. | 23:44 |
| kinghat | aka im going as soon as i figure out how to get single user mode. | 23:45 |
| kinghat | so adding a user to another group and not ONLY this group is: `sudo usermod -a -G sudo username`? | 23:52 |
