Idle Solaris PPP 4.0 Daemon Might Exit During Holdoff Period (4647938)

The Solaris Point-to-Point Protocol (PPP) 4.0 daemon (pppd) might unexpectedly exit under the following conditions.

• The pppd daemon is idle.

• The demand and holdoff options to the pppd daemon are enabled.

• A packet arrives during the holdoff period.

If the pppd daemon exits unexpectedly, a message that is similar to the following message is logged in the appropriate system log file.

current date hostname pppd[PID]: [ID 702911 daemon.error] unable
to set IP to pass: Invalid argument
current date hostname pppd[PID]: [ID 702911 daemon.error] unable to
enable IPCP

See the man page pppd(1M) for more information on the demand and holdoff options to the pppd daemon.

Workaround: Choose one of the following workarounds.

• If you do not need the pppd daemon to wait before trying to re-initiate links, do not use the holdoff option with the pppd daemon.

• Set the holdoff option value to 0.

• Run the pppd daemon from a loop script that is similar to the following Bourne shell script.

  #!/bin/sh
          while :; do
                  /usr/bin/pppd cua/b lock idle 60 demand nodetach noauth \
                  38400 10.0.0.1:10.0.0.2 holdoff 20
          done

Configuring Multiple Tunnels Between Two IP Nodes With Filtering Enabled Might Result in Packet Loss (4152864)

If you configure multiple IP tunnels between two IP nodes, and enable ip_strict_dst_multihoming or other IP filters, packet loss might result.

Workaround: Choose one of the following workarounds.

• First configure a single tunnel between the two IP nodes. Add addresses to the tunnel by using the ifconfig command with the addif option.

• Do not enable ip_strict_dst_multihoming on tunnels between two IP nodes.
