The New ceri.memphis.edu

  1. Introduction
    1. The Old
      1. 3 more or less separate computer networks
      2. poorly networked
      3. difficult to maintain
      4. difficult to customize
      5. difficult to standardize
      6. poor disaster recovery
    2. The New
      1. only Solaris but potential to integrate other Operating Systems
      2. file systems are shared consistantly and reliably
      3. this means that you can install software and share/maintain it with everyone.
      4. there is one login, one enviornment
      5. printers are installed consistantly and reliably
      6. things like home directories won't change for some time
      7. the physical location may change but the path to it will not change
      8. single sign on with ssh
      9. services are provided by the network
  2. what allows us to do this
    1. NIS: network information system contains things like:
      1. file shares: /gaia/hostname/diskname
      2. groups: trustedhosts, seisadm, seis-nets
      3. no local user accounts
      4. lpstat -a; queue name
    2. TRUSTS
      1. Policy Based Security Depends on:
        1. the host
        2. the user
        3. the process
      2. trustedhosts=
        1. the os/hardware is supported by computing staff
        2. there is a disater recovery plan for that systems os
        3. root passwd is turned over to computing staff
        4. the number of services on the host is limited
        5. all logins are logged
        6. eeprom is passwd protected
      3. only trusted hosts are allowed to make use of certain network resources: file shares (maybe printers, maybe certain hosts)
    3. Logging
      1. Internal Logging
      2. External Logging
      3. Miscellaneous Logging
  3. how do we use it?
    1. custodians of trusted hosts
      1. file ownership
      2. devices
      3. rebooting
      4. apps
    2. applications:
      1. Network Supported
      2. Custodian Supported
    3. Local vs Network:
      1. When to keep data local
      2. When to run local
    4. Secure Shell
      1. telnet and ftp
      2. rlogin, rsh, and rcp
  4. Support in general
    1. ARS
    2. Prioritization
    3. Applications
    4. Supplies
    5. Help your neighbor
  5. Future developments
    1. DiscServer
      1. Backups
      2. Quotas
    2. Generator
    3. Fiber
    4. NSF
  6. Q and A
    1. Network issues
      1. midtown mail: there is a need to retire midtown as the mail server for ceri and allow the large majority of mail to be handled by network services. how many people are currently using midtown......what plans to you have to make the transition to postoffice.memphis.edu.....what help do you need?
      2. dhcp: we will be moving the large majority of all of our machines to dhcp inside the next year or so. is there anyone who needs to have static ip address? we need to think about what this transition will include.
    2. Support for OSes
      1. PC/Microsoft
      2. Macintosh
      3. Linux
      4. OSX
    3. Your turn
