i have shell scripts in my redhat server written by previous administrator, which downloads some files from external FTP servers.
lftp -c 'open -e "repeat 10 source getfiles.script" host1' > out_get.out 2>&1 lftp -c 'open -e "repeat 10 source getfiles.script" host2' > out_get.out 2>&1
As i been informed, those scripts were working before, after some changes done in external FTP servers(host1/host2) now its stopped working.
Here in lftp commands username and password for host1 and host2 are not specified, how can it be possible to connect to external FTP servers without any credentials ?
On the host names, how to check the real IP of "host2" ? its not registered in hosts file and when i ping host1 it says unknown host. But ping host2 - displays domain name and real ip but 100% package lost.
Some thoughts: 1. host1 not registred in DNS servers 2. host2 registred in DNS servers but ping gets 100 package lost becouse firewall blocks the connection. Any other ideas ?
I have 2 DNS servers registered in resolv.conf:
nameserver X.X.X.2 nameserver X.X.X.3
# # /etc/nsswitch.conf # # An example Name Service Switch config file. This file should be # sorted with the most-used services at the beginning. # # The entry '[NOTFOUND=return]' means that the search for an # entry should stop if the search in the previous entry turned # up nothing.

Thanks a lot.
