Known Problems and Limitations

This section includes information on known problem and limitations in TOUR 2.2 and its

components.

Known Problems

There are no known problems in TOUR 2.2.

Limitations

The following limitations exist for HP-UX 11i v1 TOUR 2.2 components.

IPv6 Transport Limitations

The limitations of IPv6 included in HP-UX 11i v1 TOUR 2.2 are as follows:

• Multihomed Host Limitation

In the case where a host has multiple physical network interfaces, and there is no router

on the link advertising preﬁxes, if the interfaces are conﬁgured with only link-local

addresses, the host cannot identify the interface through which it has to send packets. If

packets are sent through an interface that is on a different link than the destination node,

the communication fails. To overcome this limitation, the interfaces must be conﬁgured

with globally unique addresses or alternatively, a router that advertises preﬁxes could be

added to the link.

• Distributed File System Limitation

Currently, NIS+, NIS, and NFS are not supported over IPv6.

• The setparms Utility Limitation

The setparms utility has not been enhanced to support IPv6 conﬁguration.

• The who -R, last -R, finger -R Commands Limitations

The who -R, last -R, and finger -R commands have not been enhanced for IPv6. Thus,

the following cases are observed when using these commands:

— The who -R and last -R commands output displays a truncated IP address when

IPv6 on TOUR 2.2 is installed and the user logs in remotely using an IP address

instead of a hostname.
