[Firebird-test] Unable to complete connection to "localhost"

[kelv <ke...@ya...>]

    Hi,
       I have installed FirebirdSS-1.5.1.4481-0.i686 on a red hat 8. When I
gbak -r a gbk file(backup from v1 firebird running on red hat 7.2).
Following error occur:
Unable to complete network connection to "localhost"...
error in reading data..
broken pipe.

I have checked that firebird server is started and "gds_db tcp/3050" was
included in the /etc/services.

Would u please advice how to I fix this problem. Thank a lot!
