Sync not starting

[itzmashy]

Trying to sync db

geth --datadir=C:/Eth/db --networkid 2061 --port 30305 --nodiscover --rpc --rpcaddr 127.0.0.1 --rpcport 8505 --ipcpath=C:/Eth/db/geth.ipc --syncmode "light"

been stuck over an hour at:

I've tried multiple times and it's always stuck ... what am i doing?

I've tried multiple times and it's always stuck

Well, several things.

• You're using --networkid 2061, which means incompatible with the rest of all regular nodes, so the only peers you can ever connect with are other peers using that exact network id.
• You've also disabled discovery with --nodiscover, so it won't actively search for any peers.
• You're node also seems to be behind a NAT, so external nodes can't connect to it, only peers on the same internal network

The only way to get something to happen would be to manually configure other nodes with the same network id (and behind the same NAT) and make them connect to your node.

yeah totally fair, i haven't sync'd for two years and all the commands have changed, and i have had a heck of a time trying to figure out how to even launch console haha

what network id should i use, and should i remove no discover?

ty for your help! @holiman

[itzmashy]

@holiman you're a genius :) i changed my command:

geth --datadir=C:/Eth/db --port 30305 --rpc --rpcaddr 127.0.0.1 --rpcport 8505 --ipcpath=C:/Eth/db/geth.ipc --syncmode "light"

and now...

thank you, friend.

@holiman , dumb follow up question if you don't mind (please bear with me, as I mentioned it's been a while), once i'm done syncing, will i be able to run commands in this window? is this the console? or do i need to launch the console in a separate window to actually interact with my wallet? And if so, how do i do that?

thanks again!

[holiman]

If you want to run in the same window, use

geth --datadir=C:/Eth/db --port 30305 --rpc --rpcaddr 127.0.0.1 --rpcport 8505 --ipcpath=C:/Eth/db/geth.ipc --syncmode "light" console

If you want to use a separate one, use

geth attach C:/Eth/db/geth.ipc

If memory serves me right, there might be some windows-quirk with named pipes, IIRC, and you may have to actually use something like

geth attach \\.\pipe\C:/Eth/db/geth.ipc

[itzmashy]

@holiman thanks again for your help!
i haven't been able to successfully attach :( lmk if i should open a new issue but when i run

geth attach C:/Eth/db/geth.ipc
i get Fatal: Unable to attach to remote geth: no known transport for URL scheme "c"

if i do geth attach \.\pipe\C:/Eth/db/geth.ipc

Fatal: Unable to attach to remote geth: parse "\\.\pipe\C:/Eth/db/geth.ipc": first path segment in URL cannot contain colon

my sync is still running in the same window

i tried this in another window: geth --datadir=C:/Eth/db --port 30305 --rpc --rpcaddr 127.0.0.1 --rpcport 8505 --ipcpath=C:/Eth/db/geth.ipc console

got:
