BXadmin:BX Migration stuff
From CCGB
This is to serve as a list of services and responsibilites to be either migrated to ITS or ECoS IT, or decom'd.
This is going to be rather long, and many services listed here will have a long list of requirements.
Services
- AFS
- Statistics:
- 306 user entries in prdb
- 98 groups in prdb
- 669 volumes (not including BK and RO) across 17 fileservers and 42 vice partitions
- ~100TB total vice partition space dedicated to AFS, most in Solaris+ZFS with at least LZJB compression
- ~30TB disk space used, after compression
- PTS users and groups sync'd from LDAP (bxAccount and bxAFSGroup objectClasses, bxAFSGroupId and bxAFSPTSName attr's)
- Stored in afs:
- Websites (31 vhosts, 8 physical servers), config files, log files, SSL certs, webalizer and associated scripts (not currently enabled, needs to go into cfengine)
- rancid, cacti, ganglia-web
- afs-pkg (/afs/bx/pkg and /afs/bx/software)
- WPKG and Munki xml repos and software packages/installers
- local YUM repositories, miscellaneous mirrors (ftp.bx.psu.edu/(software|mirrors)
- Sun Grid Engine with AFS token integration (/afs/bx/service/sge/prod)
- DNS zone files (config files are in cfengine)
- cfengine master repo
- cosign - html files, cgi's, mod_cosign.so
- Private and public FTP via k5start'd vsftpd
- Mailman archive files and list config files
- Rt 3.8.8, built for 64-bit linux and Solaris 10 SPARC (via @sys symlinks)
- Several 10's of TB of research data (/afs/bx/depot/data/)
- 214 user home directories, 5.6TB total, average 26GB in size, biggest is 414GB
- Statistics:
- Mail
- imap.bx.psu.edu: dovecot IMAP, with GSSAPI auth. Works with BX.PSU.EDU and dce.psu.edu
- Squirrelmail and Horde/IMP for web based access
- Mail routing, aliases, mailer config, and per-user mail forwarding stored in LDAP
- Sendmail on Solaris 10 SPARC for incoming MX's, delivery via procmail+Maildir, sendmail process is run under k5start
- Outgoing via password auth sendmail (smtp.bx.psu.edu)
- MX and smtp.bx are filtered via milter over IPv6 to amavisd running on wash and zoe
- Handles bx.psu.edu directly, and contains bio.cse.psu.edu virtual users and corresponding aliases
- amavisd uses both clamd and spamassassin, and does dkim and DomainKey signing/verification
- Mailing lists
- Mailman (lists.psu.edu). Some of it is in AFS, so it gets k5start'd
- lists.bx.psu.edu accepts mail from the MXes
- LDAP
- OpenLDAP
- dc=bx,dc=psu,dc=edu - syncrepl replicated between 3 machines, single-master. HDB backend
- Contains mail, users, groups, Apple OD stuff (cn=apple), RADIUS, DHCP, automount maps, sudoers
- SASL/GSSAPI binds, specifically to allow user-managed groups and mail forwarding edits (mailRoutingAddress) by regular users
- User RFC2307bis groups
- dc=dce,dc=psu,dc=edu - syncrepl, HDB backend. Contains stub entries for cosign+mod_authnz_ldap functionality with dce users
- dc=psu,dc=edu - fake directory, Perl backend. Returns fake entries for FOPS users
- DNS
- Nothing special. BIND 9 on Solaris SPARC. Many many special entries, SRV records, AAAA records, etc.
- cfengine
- git repo lives in AFS
- cfservd is k5start'd
- Controls almost EVERYTHING
- Needs to be split into separate prod and master branches for proper testing
- Configured to manage Solaris (OpenCSW), OSX (macports), Linux (Centos5, SL6, Debian Squeeze)
- Munki
- Installs pkg's, dmg's, etc on OS X. Currently set up to run on 10.5, 10.6, 10.7
- pkginfo files (xml) edited directly in AFS. Should be moved to git with separate master and prod branches for testing
- WPKG
- Installs all the Windows packages. Targeted at 64-bit Win7 as setup right now.
- Runs via BAT script at startup, configured via AD (BX-WPKG-prod and BX-WPKG-master GPO's)
- IPP
- CUPS running on a (rather old) Fedora VM. All printers are on RFC1918 network. Firewall ACLs allow access to 631/tcp from psu wireless subnet.
- No authentication or page counting, but SPNEGO auth could, in theory, be used
- RT
- Version 3.8.8. Protected behind our cosign
- installed using shipwright, with some minor modifications
- SGE
- Scheduling for most of the clusters
- Lives in AFS, with AFS token integration (set_token.sh and get_token.sh)
- Kerberos
- Heimdal 1.3.3. iprop over ipv6.
- One-way trust between BX.PSU.EDU and dce.psu.edu
- 589 principals
- Cosign
- weblogin.bx.psu.edu
- Supported login realms:
- fops.psu.edu(R_U = abc123@fops.psu.edu, R_R=fops.psu.edu)
- dce.psu.edu (R_U = abc123, R_R=dce.psu.edu)
- BX.PSU.EDU (R_U = abc123, R_R = BX.PSU.EDU)
- cosignd and monster run on 3 different machines (river, jayne, simon)
- Supports SPNEGO via background AJAX mojo that redirects to /negotiate if SPNEGO is deemed to be working. /negotiate is then protected with mod_auth_kerb (see cosign.bx.psu.edu-ssl vhost file)
- Several local patches to disable kdc verification, and change some variables around so we compare certain fields in cosign.conf before RE substitution
- NTP
- ntpd from OpenCSW on Solaris 10 SPARC
- MySQL
- mysql on early.bx.psu.edu has DBs for RADIUS accounting, core websites, RT, etc
- mysql on badger.bx.psu.edu has research related databases
- RADIUS
- Supports switch login and enable passwords on the HPs and Dell PowerConnect (the 10gig switch)
- 802.1X on the wired network, supporting both BX.PSU.EDU and dce.psu.edu realms
- Also does MAC-based authentication
- Assigns ports into vlans based on MAC or username
- Everything is stored in LDAP
- Monitoring
- Syslog - syslog-ng
- RANCID - does switch config diff'ing
- arpwatch
- nagios - 327 services, 91 hosts
- cacti - has the weathermap plugin installed. WM config files need to be updated for the current network layour
- gangila
- FTP
- vsftpd
- k5start'd so it has access to afs (svc/ftp group)
- Does anonymous and private logins for moving research data back and forth for collaborators that don't have full BX accounts or AFS at their site
- DHCP
- LDAP-based host, networks, etc
- conserver
- Provides unified console access to Sun, IBM, Dell, HP, and any standards-based IPMI Serial-over-Lan interface
- Wiki
- MediaWiki with ACL, LDAP_Group, and REMOTE_USER extensions (on my github account)
- afs-backup.pl (/afs/bx/service/afs/backup)
- Reads in volmountsDB (generated every 12 hours on all fileservers using the custom volmounts command courtesy Tom Keiser)
- Generates dsm.sys file with appropriate VirtualMountpoint stanzas for each mountpoint in the cell
- Selects which volumes to backup based on volume or path regex
- Selects policy based on volume or path regex
- Dumps current VLDB state
- Optionally dumps ACLS
- Runs dsmc incremental against selected mountpoints
- Should be updated to use the new volscan utility, currently only in openafs master, probably will be included in OpenAFS 2.0 (?)
- Networking
- HAHAHA. see BXadmin:Network
