I have a QNX system that needs to be able to respond
to two separate ip addresses.
I used the ifconfig command to produce an alias.
This seemed to work for a while. Recently the host
that it needs to talk to cannot telnet or ftp to either ip address.
The host is on the other side of a switch. I can
access the system on the other side of the switch
from a Windows 98 box but not from a VMS box or
a QNX box. I can go to another machine that is on
the same side of the switch and from there telnet
to the box.
When I disable the alias, the host can talk to the single
I have no clue how aliases work internally or how the
network configuration may affect or be affected by aliases.
Is there something that I can look at either on my QNX
system or on the host? Can someone explain how aliases
are implemented or point me to something that explains them?
