Hi Alex,
Thanks for this guide. We could create a pool using this guide. As of now we have set a basic pledge. We need to modify our pool using CNTools. What are the taxes for pool modification that includes changing the pledge, margin etc? Any guides for this?
The tax for pool modification should be ~0,2 ADA; like any other transactions…

Hello Alexd. Interested in your tutorial, I started to follow it. I have got an error executing step 2 :
alain@relay1-node:~/git/cardano-node$ git fetch --tags --all
Fetching origin
alain@relay1-node:~/git/cardano-node$ git checkout 1.25.1
Note: switching to ‘1.25.1’.
You are in ‘detached HEAD’ state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.
If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:
git switch -c
Or undo this operation with:
git switch -
Turn off this advice by setting config variable advice.detachedHead to false
HEAD is now at 9a7331cc Bump version to 1.25.1 and update change logs

Wow…that’s impressive, all the best of luck to anyone brave enough to try this for the first time lol 
Im having the same trouble as @Alain when trying to build node from scratch.
I had made several nodes with no trouble two days ago …yet since then i keep getting the same errors and cant configure a node. (2 nights no sleep)
Could it be because of Marry hard fork?
I belive it’s the same issue as:
Hello Alexd1985,
Step 2 successfully executed thanks to you!
alain@relay1-node:~/git/cardano-node$ cardano-cli --version
cardano-cli 1.25.1 - linux-x86_64 - ghc-8.10

alain@relay1-node:~/git/cardano-node$ cardano-node --version

git rev 9a7331cce5e8bc0ea9c6bfa1c28773f4c5a7000f
Have you by any chance identified my error (s) because I still have two nodes to install and I wouldn’t want to go wrong again ?!
Thanks again for your support.

It happens usually if u already have 1.25.1 … ur node was clean before? Or aleady had 1.25.1

No nodes before… I’m a complete newbie in Cardano.
Best regards. Alain 
Then, next time try without
git pull origin master
Have you looked at my Ansible role? I managed to fix most of these issues on there.
I too am working through the coincashew guide. I’m using an aws t3a.medium machine (2 cores, 4GB RAM)
I get stuck resolving dependencies on the command:
cabal configure -O0 -w ghc-8.10.2
Eventually i get a:
client_loop: send disconnect: Broken pipe
I figured out that it was ssh timing out and used the following guide to extend the ssh keep alive from the server: https://www.simplified.guide/ssh/disable-timeout
Did you ever complete your install? I may try this one… I’m giving it another try now.
Cheers

Hello there,
Following the tuto at Step 4 (connect the node to each other) for 2 relays and 1 BP, I have implemented this topology on the BP :
{
“Producers”:
[
{
“addr”: “relays-new.cardano-mainnet.iohk.io”,
“port”: 3001,
“valency”: 2
},
{
“addr”: “144.xx.xx.21”,
“port”: 6000,
“valency”: 1
},
{
“addr”: “144.xx.xx.34”,
“port”: 6000,
“valency”: 1
}
]
}
The 3 nodes seems to communicate each other. What asks me question is that the BP sends to peers and to the relays, but doesn’t receive any Input, since 2 hours. I don’t see the relays IP (but they are in the “OUT”)… However the BP is accessible by Telnet from the 2 relays (no issue with the firewall) Is it normal ? Can I go on with the tuto ?
Thks for information…
The nodes should be synced ; also did u checked on relays if topologyupdater was modified properly (custom peers line)
Cheers,
Nodes are synced and “custom peers line” OK" (1.1.1.1:6000)
:)) 1.1.1.1:6000 was an example, replace 1.1.1.1 (and port in case u started BP with another port) with your Producer IP for both relays, and restart them
sudo systemctl restart cnode
after this operation you should see them on BP
PS: I added a comment in Procedure to avoid this confusion on future
Cheers,
