FTP Issue with Host name

[Former Member]

Hi All,

When i tried to send the file to other FTP server with host name i am getting below error.

Error when getting an FTP connection from connection pool: com.sap.aii.af.lib.util.concurrent.ResourcePoolException: Unable to create new pooled

resource: UnknownHostException: ftp.kms.telnet.vector.com.

But i am able to send the file successfully using IP address.

Can anyone pls suggest if any additional settings needs to be done in file adapter.

Or any other setting needs to be taken care.

Please advise.

Thannks,

Swetha

In your LAN, FTP server is registered with the IP address not with the Hostname, that's the reason you are seeing this error. In my past, I experience the same, however I continued how that was worked.

Hi Swetha,

You need to contact your Basis team or your FTP maintanance team so that they would be able to help you if you are able to connect with your IP and not using Host name

You need to contact Basis/Networking Team, and ask them to add Hostname/IP in Host definitions.

Hi,

If it is working with Ip address and not working with Host name means the host name is not mapped to the IP address . Please inform to your Basis team . They will help you.

Hi All,

Thanks for your quuck response.

I need small clarification. Actually my XI system is in server "sap.tims.hp.com" and trying to send file to thirdparty

ftp server i.e "ftp.kms.telnet.vector.com". So here do i need to ask thirdparty FTP vendor to register DNS name in their host definitions or do we need to register host name in my server i.e "sap.tims.hp.com".

Please confirm and advice how can we register hostname in host definitions i mean where we have to go to register

host name in host definitions.

Thanks,

Swetha

Hello Swetha,

NO. The Hostname definition, need to be putted/registered into your Sap XI Local Network DNS or directly into Sap XI System's Host File

Probably, your XI system sap.tims.hp.com is under a LAN network, under a DNS server. You need to ask to Basis Team to add 3rdParty Hostname definition (ftp.kms.telnet.vector.com) into DNS server.

Other easier solution, is to put 3rd Party Hostname definition (ftp.kms.telnet.vector.com) in Host File of your Sap XI System (sap.tims.hp.com)

Hi Swetha,

You need to lineup/register the ip address of FTP to ftp.kms.telnet.vector.com(FTP host name).

Hi Spantaleoni,

Thanks for your quict response.

I have added in host file as 'IP Hostname' like and tested the scenario but still facing the issue. I have added the IP and host

name in below path.

C:\WINDOWS\system32\drivers\etc.

Do we need to add in above path or any other host file is there in which i need to add.

Please advice.

Thanks,

Swetha

What is the string that you have added?

Note that you need to restart system or "browser" to be affected by this modification.

HI Spantaleoni,

I have added in below way.

125.23.46.78 ftp.kms.telnet.vector.com

I also restarted system.. but same issue.

Do i need to add above entry in XI server?

Thanks,

Swetha

Excuse me... i don't understand clearly.

Where have you inserted this string ??

You need to put the string that you written above in HostFile configuration of your XI Server

Hi Spantaleoni,

I have added in hosts in below path in my system.

C:\WINDOWS\system32\drivers\etc

I think its not correct. Can you please tell me how can go to host file in configuration in XI server.

Pls guide me.

Thanks,

Swetha

>>I have added in hosts in below path in my system.

this is wrong..

why dont u ask ur basis team?? its a few minutes job for them...

[Former Member · Accepted solution]

If your XI system runs on UNIX based system, the hosts file is /etc/hosts. The file can be edited by server administrators.

Adding the host entry to /etc/hosts is not a good practice. If you make changes to the host entry you will have to restart the XI application and on the long run, if you add a new instance on a new server, you will have to remember to put the host entry in that system's host file.

Please get the network team to help you out.

Hi,

Basis people are not aware of adding in host file, for that reason i am asking input here.

My XI ssytem runs on OS level i.e on AS400.

Basis team tried to reach host file by mapping into server, but they are unable to find host file. Do i need to ask OS level expert to add entry in host file.

For my knowledge, can you pleae give me the path of host file at OS level if you have any idea.

Please advise

Thanks,

Swetha

Hi Swetha,

First thing I understood from your previous replies is that you added the host name details in your personal computer and not in XI server system. If so the details need to be added in XI server system.

Second thing is your receiver FTP is third party as you said and there may be some firewall settings blocking your side or also in the FTP side as well. So you have to contact the network and basis team support to resolve this like opening ports etc.

Great, this is the right approach!

Under ETC FOLDER there will be a host file double click on that and enter your host name and against it IP address and it should work

[Former Member · Accepted solution]

The hostname definition, must to be added in Server host definitions or in DNS server host definitions, not in local machine.

Hi All,

Thanks for you valuable inputs, it solved my problem. Ponts rewarded.

You need to map this Hostname into Local Network DNS configuration, or simply map the combination of Hostname-IP into Host configuration of your system.

Example:

10.xx.xx.xx <SampleHostname>
