ftp between two HP-UX servers

Adrian Sobers2 — Fri, 01 Oct 2004 10:55:45 GMT

I would like to ftp some files from one server (running HP-UX 11.11) to another server (running HP-UX 11.00).

Here is the situation:

ftp 2 files (IRDS.tar.Z, IRDS2.tar.Z) from this location on new server:

/opt/oracle/data/orabackup

to these locations on old server:

/opt/oracle12/newlogs (IRDS2.tar.Z goes here)
/opt/oracle10/backup (IRDS2.tar.Z goes here)

How do I go about this process? Latest quality and hardware enablement patches installed on both machines.

Adrian,

Automating 'ftp' means hardcoding the passwords somewhere. Like .netrc or in the ftp script itself. The best way is to install openssh (you can get it from software.hp.com for free), setup public/private authentication and use 'sftp|scp' without passphrase mechanism.
If you are copying the files from systemA to systemB as the user 'oracle1 on systemA' and 'oracle2 on systemB', then follow these commands once you installed ssh.

$ssh-keygen -t dsa -N ''
( press enter for all questions)
cd .ssh
Copy id_dsa.pub file onto /tmp dir of. Logon to systemB
cd
mkdir .ssh
mv /tmp/id_dsa.key authorized_keys
chmod -R 700 ~/.ssh
(Logon to systemA)
scp some_file oracle2@systemB:/home/oracle2/some_file

It shouldn't ask for a password.

on new server:

$ ftp oldserver

> bin
> lcd /opt/oracle/data/orabackup
> cd /opt/oracle12/newlogs
> put IRDS2.tar.Z
> cd /opt/oracle10/backup
> put IRDS2.tar.Z
> quit

When I ftp oldserver like:

# ftp 200.200.XXX.X

ftp timed out

happens all the time...

Sounds like ftp services may not be running on remote system.

If the IP was incorrect, you would get:

ftp: connect: No route to host

Hi,

If you are able to ping to the server, then there is a good chance for any of these possibilities.

1. Firewall setup in between that is not allowing ftp access.
2. ftp is not enabled on the ohter host. Check the line 'ftp' in /etc/inetd.conf. It shouldn't be commented out.
3. ftp is disallowed on the other host. Check /var/adm/inetd.sec file for any filters. If you are using tcp_wrappers (you should see ftp line containing tcpd entry in your inetd.conf file.

For reasons 2 and 3, you will get 'connection refused' messages rather than timeout messages. But it doesn't hurt to validate them. For any changes related to 2 and 3, you will need to refresh inetd as (inetd -c)

Hi mate,
Since you are in the process of willing to learn all sorts, why not go for NFS, your RP5430 is a good candidate for a NFS server, the D350 would be the client:
You can use sam for this task:
export /opt/oracle/data/orabackup
configure to allow the other box for root access (you never know)
When done,On the D350, create a new mount point like I dont know /mt_nfs

Then mount the exported filesystem on it
mount :/opt/oracle/data/orabackup /mt_nfs
cd /mt_nfs, can you see your files? just copy them where you wish...

All the best
Victor.
P.S.
Be sure you have each box knowing about the other in /etc/host if you are not using DNS...

Could you please post more details steps Victor? I'm very green remember ;)

On the old server, the only line in my inetd.sec that is uncommented is:

dtspc allow 127.0.0.1 loopback

In the inetd.conf here are the uncommented lines containing "ftp":

ftp stream tcp nowait root /usr/lbin/ftpd ftpd -l

tftp dgram udp wait root /usr/lbin/tftpd tftpd\
/opt/ignite\
/var/opt/ignite

Help? Anyone?

I can actually ftp from oldserver root prompt.

I cannot ftp from newserver root prompt.

:(

I can ftp newserver from newserver so it's not a problem with the ftp I'm assuming.

attached is the output from:

# netstat -r

Hi Adrian,

Can you ping and telnet to the old server from new server?. If so, then the problem is only with ftp. If not, then it's a network problem that you would need to fix.

You would be checking ftpd configuration on 'old server'. Can you be able to ftp to the old server from any other server on the network?. How about ftp from old server to itself?

I can ping from oldserver to newserver.

When I telnet from oldserver to newserver:

root:INLAND3>telnet 200.200.120.3
Trying...
Connected to 200.200.120.3.
Escape character is '^]'.
telnetd: /dev/pts/ta: No such file or directory
.
Local flow control off
Connection closed by foreign host.
root:INLAND3>

So is this network problem then?

Sorry Adrian,
I wasnt feeling well and gone home, I will try my best to assist you but I feel very dizzy...

Lets see how you are configured network wise:
from
box1 -> ping box2
box2 -> ping box1
OK?
Now same but instead of ping-> nslookup
but with a) ip.address then hostnames

What do you have in the file /etc/nsswitch.conf?
Do you have a /etc/resolv.conf file?

Are the boxes declared in /etc/hosts?
What are the permissions on these files?
(read for every one?)

Courage!

Re: ftp between two HP-UX servers

Victor BERRIDGE — Fri, 01 Oct 2004 14:53:44 GMT

One reason if you are correctly configured (files /etc/hosts DNS...) to be able to ping and not telnet is network:
You may have some trouble with you lan interface: the interface in the box or speed/protocol mismatch it happens when it badly negociate with the switch port or if something changed...

Re: ftp between two HP-UX servers

Adrian Sobers2 — Fri, 01 Oct 2004 14:59:18 GMT

I think it is a problem in the /etc/hosts file on new production server.

root:INLAND8>nslookup 200.200.120.8
Using /etc/hosts on: inland8

looking up FILES
Name: inland3.irdbb.com
Address: 200.200.120.8
Aliases: inland3

root:INLAND8>

if case is relevant then inland3 is supposed to be INLAND3 although the IP address shouldn't make a difference no?

Adrian Sobers2 — Fri, 01 Oct 2004 15:03:45 GMT

I think it's problem with hosts file. Thing is it has bin listed as the owner. I can't seem to modify/save changes in the hosts file?
