Description

This server is the open root server for SIG SysAdmin, where members of the SIG can play around, learn, and work on projects without worrying about messing up a working mission critical server. All files on the server should be backed up elsewhere is important as this server could get wiped at any time or made inoperable without an OS re-installation. Those who want access should join the SIG and request access. An ACM account is needed. The initial setup is minimal so further setup might be needed to make some basic functions work. Additional information about the ACM network or further access to some systems may be needed for some projects, ask an Admin if you need it, integration of one system into or with another is an important skill to learn.

Status/Issues

  • Found to be unavailable for about 2-3 weeks now through SSH ~clee231~
    • However it is still up and “pingable”
    • Can anyone else confirm this problem? Is it just me?
    • [Resolved.. March 6, 2012]
  • clee231 broke the network [April 1, 2012]
    • Reverted changes, but server can no longer connect to ldap server
    • No one can login except root at the moment
    • Researching for fix… Maybe a DNS issue?
      • unable to ping ad.acm.cs
        • able to ping ip for ldap server
        • walter said networking with the VMs do pass on ICMP echo packets, so pinging doesn't work.
      • Temporary Fixed… Added entry to /etc/host [April 2, 2012]
        • nscd cache cleared, but still not working
  • There are definitely some stability issues with this server… ~clee231~
    • Many times, the server is inaccessible through ssh(at least for AD users).
