Fatal: Unable to attach to remote geth: connection refused

[casm3]

Hi, guys, how are you doing? I'm trying to run an ethereum experiment but I am having some issues related to geth attaching

I have two machines, one as client and the other one as the node that i am trying to apply the benchmark,
both of them runs ubuntu server 20.04 LTS, and connect to each other using SSH. My geth.ipc is created, meaning that the blockchain is started

Thanks

you may try by sudo before the geth
or check the code mining above in start-mining.sh it has not run properly by the update of command line in geth, then it can connect back again in geth attaching

under is my .sh code has been fixed
#!/bin/bash
cd dirname ${BASH_SOURCE-$0}
. env.sh

nohup geth --datadir $ETH_DATA --nodiscover --ws --authrpc.addr 0.0.0.0 --authrpc.port "${RPCPORT}" --http.corsdomain "*" --rpc.gascap 0 --maxpeers 32 --networkid 15 --unlock 0 --allow-insecure-unlock --password <(echo -n "${PWD}") --mine --miner.threads 2 > $ETH_DATA/../eth_log 2>&1 &

sleep 1

for com in cat $ETH_HOME/addPeer.txt; do
geth --exec $com attach ipc:/$ETH_DATA/geth.ipc
done
