 Posted: Fri Jun 26, 2020 9:09 am Post subject: How do I (temporarily) specify an IPv4 rsync server? |
 |
|
Does some way exist even to do that? Yes, I know that I can set a specific mirror, but sometimes I find myself connecting to the internet in places where the hardware doesn't support IPv6. I would like to have the capability of specifying IPv4 on the command line (something like "emerge -4 --sync", or even having portage failover to IPv4 when it can't connect to an IPv6 address.
Thank you in advance. |

| `ip -6 route flush scope global` might help, should cause it to fail immediately trying to connect to outside v6 addresses. |

It does fail immediately (even without that command, since I only have an IPv4 address when connecting at certain locations). The command returns this:
| Code: |
# emerge --sync
>>> Syncing repository 'gentoo' into '/usr/portage'...
>>> Starting rsync with rsync://89.238.71.6/gentoo-portage...
>>> Checking server timestamp ...
rsync: safe_read failed to read 1 bytes [Receiver]: Connection reset by peer (104)

>>> Starting retry 1 of 1 with rsync://[2a00:1828:a00d:ffff::6]/gentoo-portage

Actually, the error in data stream message might have something to do with it, but I don't know the cause of that (or how to fix it) either. :) I still think that portage should never try to connect with IPv6 if the client doesn't have an IPv6 address. |

Yes, I know I can do that, but I asked for a temporary solution (without changing mirrors, which I most likely will forget to change back when I reconnect to a network that supports IPv6). I would like to have the ability to specify "use IPv4 just this one time" (yes, I use a mirror that supports both). |

Not sure, but I think | Code: | | FETCHCOMMAND_RSYNC="${FETCHCOMMAND_RSYNC} -4" emerge --sync |
should probably work. |

The idea is a sound one, but I think as written, it will not work. OP likely does not have a shell environment variable named FETCHCOMMAND_RSYNC, so the use of the variable will expand to nothing, and the resulting variable will not be a valid command. Putting the same in make.conf might work, or OP could look up the stock value of FETCHCOMMAND_RSYNC and assign that first.
On further consideration, it might be easier to use PORTAGE_RSYNC_EXTRA_OPTS, which defaults to nothing, but is added to the relevant command. |
