Networking updates

• Unfortunately the way Legato does name resolution it will fail to resolve the backup server names and the short name of your computer.
• Updating Windows hosts files
  • Start Menu -> Programs -> Assessories -> Right Click on MS DOS Command Prompt -> Run as administrator -> OK
  • cd \Windows\Systems32\drivers\etc\hosts
  • You will need to know the hostname of your machine - for example we will use scspcxyz.cs.uwaterloo.ca below
  • nslookup scspcxyz.cs.uwaterloo.ca - write down the ipaddress - we will use 129.97.168.123
  • notepad hosts
    • Append these two lines
      • 129.97.167.100 backup.cs
      • 129.97.167.100 backup-0.cs
    • Append your host IP address and short hostname without any domain specs.
      • 129.97.168.123 scspcxyz

Windows 7 Legato Configuration

  • Open Start Menu -> Programs -> Networker User

Ubuntu and Debian Users

Ubuntu Release Specific Notes

• Ubuntu 10.10 now has a recover command that can undelete files and conflicts with the Legato install

    • dpkg -i (name of debian package)
  • edit /etc/init.d/networker and append "-s backup.cs.uwaterloo.ca" to lines ending with /usr/sbin/nsrexecd
    • They will look like: "$NSR_ENVEXEC" -u "$NSRRC" -s "$NETWORKERRC" /usr/sbin/nsrexecd -s backup.cs.uwaterloo.ca

DEB Package method

• We are still using the RPM method because they include MAN pages

RPM method using alien to convert to DEB package

• http://packages.ubuntu.com/lucid-backports/amd64/libstdc++5/download

Redhat users install notes

• IST download page: http://ist.uwaterloo.ca/download/networker/current/index.html
• Direct links - chose based on your architecture. Use the arch command if unsure:
  • 32bit:
    • wget http://ist.uwaterloo.ca/download/networker/current/nw_linux_i686.tar
    • tar xf nw_linux_i686.tar
  • 64bit:
    • wget http://ist.uwaterloo.ca/download/networker/current/nw_linux_x86_64.tar * tar xf nw_linux_x86_64.tar*

  • cp networker /etc/init.d/networker
  • chmod 755 /etc/init.d/networker
• The /nsr gets created when you start the service!
  • service networker start

SUSE 10 users install notes

• zypper install openmotif (you need this)
• Follow the Redhat user install notes
• Note: I think it is safe to ignore the error grep: /etc/syslog.conf: No such file or directory

TCP wrapper settings

If you use TCP wrapper security add the following configuration

/etc/hosts.allow

• ALL: backup.cs.uwaterloo.ca

Firewall issues

• IF you use a firewall add backup.cs and backup.math to your rule set

Ubuntu Shorewall rule (allow TCP7937-9936 from backup.cs)

MAC Ports

• OSX, TCP ports 7937-7939 and 10001-10100 should be sufficient.

Redhat Firewall

• Update firewall by editing /etc/sysconfig/iptables place these lines before COMMIT

   
        -A RH-Firewall-1-INPUT -m state --state NEW,ESTABLISHED,RELATED -p tcp -s 129.97.82.10/32 -j ACCEPT 
        -A RH-Firewall-1-INPUT -m state --state NEW,ESTABLISHED,RELATED -p tcp -s 129.97.152.100/32 -j ACCEPT 
   

• Using GUI Tool For the firewall, use the GUI tool * "system-configure-securitylevel" [desktop--system--security level](run it from the commandline if you must).
  • • It writes the file /etc/sysconfig/system-config-securitylevel, which you can modify under the covers if necessary.
    • The GUI syntax is a comma-delimited list of port:protocol pairs, eg 22:tcp for SSH
    • The syntax in the file is one rule per line, of the form "--port=nnn:prot", eg "--port=22:tcp" opens SSH.
• Note that for the GUI you will have to know the system's root password, or run the command from the commandline via sudo.

Mac OS X client installation

• download nw_macosx.pkg on your desktop.
• Rightclick nw_macosx.pkg -> Open
  • Use all defaults
• Open Terminal
  • Finder -> Terminal
• Become root
  • sudo bash
• echo backup.cs.uwaterloo.ca >/nsr/res/servers
• echo backup-0.cs.uwaterloo.ca >>/nsr/res/servers
• /bin/launchctl stop com.emc.NetWorker
• Update Firewall to permit access
  • /usr/bin/nsrports -S 7937-7941
• /bin/launchctl start com.emc.NetWorker
