I have 2 computers, main ones' OS is windows 10, 2nd one Ubuntu.

My windows 10 uses WireShark V1.2.4 .

Ubuntu uses V2.6.8 .

When capturing packets between computers I noticed the V1.2.4 is showing UDP and TCP Streams in the packet.

But I am not seeing the UDP or TCP Stream in the V2.6.8.

I can go to "Analyze > Follow >", and follow them.

However, I would like to see that data in the packets just like the V1.2.4 shows it.

Question: How do set packet capture to enable UDP and TCP Streams in V2.6.8?

Version 2.6.8 (Git v2.6.8 packaged as 2.6.8-1~ubuntu18.04.0)

Version 1.2.4 (SVN Rev 30978)< Windows 10.

Are you sharing the same capture, or are you capturing on the 2 different systems and seeing different results?

You should upgrade the version on the Win 10 system. 1.2.4 was EOL'd Jun 30 2011 and there is no support whatsoever for it.

The 1.2.4 is fine for now.

"capturing on the 2 different systems and seeing different results?"< Yes!

Version 2.6.8 is not showing UDP or TCP streams in packets.

Version 1.2.4 shows those steams in packets.

The "Version 2.6.8 (Git v2.6.8 packaged as 2.6.8-1~ubuntu18.04.0)" is the issue.

The packets are missing the UDP & TCP Streams in the capture.

The readable ASCII text is not there in V2.6.8.

Version 2.6.8 is not showing UDP or TCP streams in packets.

What do you mean by "in packets"? Analyze > Follow displays the streams in a separate window. You say "I can go to "Analyze > Follow >", and follow them." - does that mean that the separate window does pop up in 2.6.8?

Are you referring to the ASCII text that appears to the right of the hex dump in the "hex dump" pane?

yes! and the readable ascii text is there. Works in 1.2.4 version too.

https://ibb.co/DD2VMRF ,V1.2.4 Windows 10. ASCII text in packet.

https://ibb.co/bdBN8Tg ,V2.6.8 Ubuntu. No ASCII text in packet.

I hope these pic help understand my question.

That is the same UDP/data in packet in both pics, V1.2.4 win10 shows text in packet, V2.6.8 Ubuntu does not.

I think you have changed the display to show text encoded as EBCDIC.

Right click the text area in the Ubuntu version, and select "...as ASCII".

Thank you! Thank you! Thankyou! Never did ever think to right click that pane! I am disappointed in myself for not finding that! I now have text in packet!
