git

I keep forgetting the commands to start git, here is an example echo "# cscourses" >> README.md git init git add README.md git commit -m "first commit" git remote add origin https://github.com/DelHart/cscourses.git git push -u origin master

ldap search

This is a useful query to see what the ldap has from the commandline

 ldapsearch -h HOSTIP -D "cn=DAEMONUSER,ou=Process Accounts,dc=blah,dc=ntds" -w DAEMONPASS -b "ou=People,OU=blah,dc=blah,dc=ntds" "(|(memberOf=cn=ntds.blah.managed.blah.blah.blah,ou=Groups,ou=blah,dc=blah,dc=ntds)(memberOf=cn=ntds.blah.blah.blah.lab_access,ou=Groups,ou=blah,dc=blah,dc=ntds))" \* \+

Note: truecrypt sudoer

ALL ALL=(root) NOPASSWD:/usr/bin/truecrypt

Note: boot to console

add "text" in the /etc/default/grub file @ GRUB_CMDLINE_LINUX_DEFAULT="quiet splash". Run update-grub to rebuild the cfg file. Lastly reboot.

Note: multibootusb

Note: Using the program multibootusb to carry multiple live "cds" on one usb stick.

virtual machine prototype

To start I use VBoxManage startvm vmnamehere

I have the base os installed
  installed ssh server
  now working on authentication...
       looking at aptitude log to find packages...
           ldap-auth-client
           ldap-auth-config
           auth-client-config
           libnss-ldap
           libpam-ldap
           nscd
           [INSTALL, DEPENDENCIES] libgssrpc4:amd64
[INSTALL, DEPENDENCIES] libkadm5clnt-mit9:amd64
[INSTALL, DEPENDENCIES] libkadm5srv-mit9:amd64
[INSTALL, DEPENDENCIES] libkdb5-7:amd64
[INSTALL] krb5-config:amd64
[INSTALL] krb5-user:amd64
[INSTALL, DEPENDENCIES] libxcrypt1:amd64
[INSTALL] libpam-krb5:amd64
[INSTALL] libpam-unix2:amd64






skipping the install config, I am going to copy the config files that are working
   ldap.conf
   krb5.conf
   nsswitch.conf

stopped/started nscd and the authentication piece looks ok

now test a few more things, and then the prototype should be ok
  need to set up fstab...

I think I'm mostly done.  Time to start working on www
  shutting down the prototype
  cloning
  changing the ip address to 44 for now
  changing the mac address
  migrating



Moving to command line mode

Installing apache2
now mediawiki
   .. for some reason it wants a running postgresql
   .. now to find the config stuff
  

virtual machines

I'm going to try using virtual machines for most of the boxes, so I'm setting a prototype first.

TODO:
   request bios passwords
   set intel vt for direct io on
   enable remote wake up

1. Set the network device to bridged so I can statically assign ip
2. Upgrade packages
2a. I'm not confident the upgrade was fully effective, so I'm going to start over on the virtual image
3. Setting up the authentication via libpam/libnss

Setting up the file server
This will be a physical only machine
Need to migrate a disk over for additional space
Will set up another machine is capable as taking over, in the mean time though it will run a virtual machine(s) to support other things.

1. updating
2. changing to text boot
3. adding ssh
4. adding btrfs
5. changing /home to btrfs

update:
The file server is setup and operational

opensuse 13.2 / sssd

I've tried before, with some trouble getting the authentication to work correctly. Trying again. Installing a fresh copy of 13.2 on a project room machine Install complete, going into yast to configure network and set up nfs mounting, need to work on wireless connectivity also setting up the wireless password, it is stored in /etc/sysconfig/network/ifcfg-w.... whatever the device is wireless working, networking ok, nfs up, had to delete the usr/local btrfs subvolume... perhaps reconsider mounting /usr/local... now kerberos trying yast under user authentication, it seems to be at least installing the right packages for me yuck..., sssd is not something that is working for me, and there is no clear path to fix it... (I had started this a few days ago, but had left it as a draft...)

mint / nscd

So, I've been trying mint and so far not too bad. The gui is a bit different and my ubuntu/debian is rusty, but it is coming back. One headache I had forgotten about is nscd, it caches data, so when you make changes to the authentication system it helpfully returns the old data. blah. I spent a couple hours re-learning that lesson. On the bright side, it looks like mint will work out. This page was useful http://www.openldap.org/lists/openldap-technical/201403/msg00107.html

hard drives

In Ausable 309 on Friday we swapped drives between 157 and 158 to verify that the one in 158 was bad. It was. Strangely enough, when trying to boot 158 later, it gave an out of memory error in grub. I installed another copy of the OS, and grub was then happy. In Ausable 113, this morning 104 was showing hard drive problems. I fsck'ed it, and it boots now, but it probably needs to be reimaged.

Google drive/java

Working on using the google drive api, unfortunately Perl is not supported, so I'm going with Java.

Working with Java again, after having been away from it a while makes me realize what I don't like about it.  It isn't so much the language, but the culture of Java projects is that the focus is on the code, rather than on building something useful.  There is little optimization for the common cases, and great concern for the corner cases, that it makes programming in it very tedious.

Anyways,

The oauth, is understandable, but an added complication.

One thing that threw me for a while is the different permissions.  In the provided example it defaults to only programs created by the app, which I missed, and caused me to wonder why I couldn't get a directory listing.

I will have more work to do later, but I got all of the files added for now.  I'll see how useful the spreadsheets are before deciding how much more work to put into it.
