that would NOT let me upgrade to a newer version via SSH giving some erroneous error during the copy of just one of the files. I forget which. Oddly, it worked if you were trying it via telnet and this bug was fixed in the release I was trying to upgrade to.
It was a known bug that TAC told me about… unfortunately they told me after they insisted the file copied properly and to reboot the device despite the reload check failing. Naturally this caused the line card to fail to boot properly. Fortunately I was able
to recover easily enough but it was very annoying. Other routers I used telnet (after turning it on) and the upgrade process went smoothly.<o:p></o:p></span></p>

I've been through the TAC and told it will be fixed in the next patch release for 5.6 and 5.7.<br>
<br>
Zeroing out the key and recreating seems to work sometimes and/or briefly. Telnet is unaffected if you can get to the serial console to enable it :)<br>

<br>
In other news, I just had ssh stop working on 5 MLX routers, all running<br>
5.6d:<br>
<br>
$ ssh myrouter<br>
invalid public DH value (1/1024)<br>
Disconnecting: bad server public DH value<br>
$ <br>
<br>
When will Brocade get their act together on their SSH implementation?<br>
Does this really have to happen on every third firmware release?<br>

It is much easier to suggest solutions when you know nothing about the problem.<br>
