cant re-image ASA 5500 to specific FTD firmware

jbates5873

Level 1

Hi Everyone, im having an issue where i am unable to download the pkg file for re-imaging my ASA to the unit. I am trying to flash a clean, fresh copy of 6.4.0 FTD firmware to this unit as a POC for upgrading a HA cluster of these units.

Running the commands in ROMMON as per the guide.
ASA→Threat Defense: ASA 5500-X or ISA 3000

(Source: https://www.cisco.com/c/en/us/td/docs/security/firepower/quick_start/reimage/asa-ftd-reimage.html)


It will download the LFBFF via TFTP, but will not download the PKG file. It just fails. I know its not an issue with the endpoint where the files live, as i was able to download the LFBFF file moments before using TFTP. When looking at packet captures, I see that there are only 4 packets, and they are TCP Retransmissions, I have a packet cap saved of it, but am unable to upload to the post. But can do some other method if needed.

 

No matter what i do, i always get error code 110, which i cant find anything on. And it only ever performs the 4 connection attempts to the server. I even tried HTTP and SCP, but still got similar results.

Im hoping for some guidance on where to go from here to get these units to install the 6.4.0 FW. I can confirm that my ROMMON version is also 1.1.8 which the documentation states is the minimum.

Your procedure output appears correct up until the "Upgrade aborted" message. Have you tried to use ftp against the target server from any other system? Seeing 4 TCP SYN packets without any ACK or SYN ACK completing the TCP 3-way handshake usually indicates the server is not accepting the connection (port/service not listening or host firewall enabled). Your successful use of tftp isn't directly comparable since it uses different protocol/ports.

Have you tried with a more recent version of the software? The 6.4.0 version you are using is over 4 years old and the ASA 5508-X supports much newer releases (e.g., 7.0.5: https://software.cisco.com/download/home/286285773/type/286306337/release/7.0.5)

Hi Marvin,

Yes i know that the 6.4 version is quite old, I am staging a POC upgrade for some customers that have some 5500 units in HA currently on 6.4.0. So we want to build up the staging environment as close as possible to current, then do the upgrade to a more recent version.

I can confirm that another system on my network can access the FTP server running on my laptop. And i can confirm that the firewall is open etc.. So it shouldn't be that. This is why i'm stumped as to what the issue is. And not finding anything about the error code 110 also doesn't help a lot.

I have also tried multiple different HTTP and FTP servers for this. The image below is another host on my network connecting to my FTP server

Screenshot 2023-05-18 134746.png

Have you tried providing the ftp username and password in the "system install ftp://..." command.

As shown here: https://www.cisco.com/c/en/us/support/docs/security/asa-firepower-services/118644-configure-firepower-00.html#anc7

Yes, even if i use an anon account with no credentials, it still does not work.

 

I can connect to the FTP server from another host using both auth and non auth.

also, wanted to mention, that doing it via a HTTP method does not work either. And i can confirm that the files are accessible to other hosts on the network.

Given all the steps you've tried, I would begin to suspect you may have a hardware issue with the SSD. 

I would recommend opening a TAC case if you have a support contract.

Turned out that it was a GPO that was re-enabling my windows firewall as soon as i closed the window after disabling it.

 

I have managed to re-image the unit now.
