Hello,

We are using Transus provider to send messages to our clients.

Reception is fine, no issues.
For sending here is the error we have :

Here is our current partner configuration :

 <receiver name="Partner"/>
        <attribute name="as2_mdn_options" value="signed-receipt-protocol=optional, pkcs7-signature; signed-receipt-micalg=optional, SHA1"/>
        <attribute name="receiverIDs" value="OUR_ID"/>
        <attribute name="subject" value="File $attributes.filename$ sent from $sender.name$ to $receiver.name$"/>
        <attribute name="remove_cms_algorithm_protection_attrib" value="false"/>
        <attribute name="prevent_canonicalization_for_mic" value="false"/>
        <attribute name="sign" value="SHA1"/>
        <attribute name="senderIDs" value="Company"/>
        <attribute name="resend_max_retries" value="3"/>
        <attribute name="as2_receipt_option" value="http://xxx.transus.com:xxxx"/>
        <attribute name="content_transfer_encoding" value="binary"/>
        <attribute name="protocol" value="as2"/>
        <attribute name="encrypt" value="3DES"/>
        <attribute name="as2_url" value="http://xxx.transus.com:xxxx"/>
        <attribute name="rename_digest_to_old_name" value="false"/>
        <attribute name="name" value="Lulubuy-to-Bol"/>
        <pollerConfig enabled="true"/>
    </partnership>

Maybe are we missing something here ?
Transus seems to be a very old EDI provider. What would be the best configuration ?

I am not clear how you are using OpenAS2.
You say you are using Transus and the error screenshot you show is not an OpenAS2 screen so It is impossible to help you without a lot more clairty.
Your best starting point is the troubleshooting section in the OpenAS2HowTo.pdf that comes with the OpenAS2 package.

Try to set remove_cms_algorithm_protection_attrib to true on the partnership level.

<attribute name="remove_cms_algorithm_protection_attrib" value="true"/>

No it didn't worked...

I might be wrong since it was a long time ago I connected with a N-Software based Trading Partner. N-Software is not an actual AS2/EDI software but a set of libraries left for the user to implement and configure their own solution. After some network sniffing and log combing we detected that the particular implementation of the partner didn't support chunked-transfer. To disable Chunk-Transfer in OpenAS2 just read the "14.5. Content Length Versus Chunked" section in the manual. TLDR; You can try setting: or in the partnership configuration. Regards, J

You're right @igwtech, we needed to add <attribute name="no_chunked_max_size" value="LARGE_NUMBER_IN_BYTES"/> I put the value 104857600.

Now, reception/sending works perfectly.

Thanks a lot!
