 Posted: Mon Dec 30, 2019 1:46 am Post subject: Networking issues with ssh and rsync |
 |
|
It was necessary to replace my 10+ year old Gentoo Server "MasterTux" because the hardware was failing. So I decided to do a fresh install rather than just syncing the old system to new drives. Networking was setup using Gentoo's Home Router Guide several years ago. I reused the configs from the old server where everything worked very well. The Server is using dhcpcd and dnsmasq.
All clients on the LAN have internet access, dnsmasq is assigning the correct IP's to the correct devices and IP printing is working. However no clients on the LAN can sync to the Servers "portage repo" and No client can ssh to the Server using it's hostname. So I have seriously missed something but don't know where.
Syncing errors from the clients: | Code: |
@ERROR: chroot failed
rsync error: error starting client-server protocol (code 5) at main.c(1657) [Receiver=3.1.3]
!!! Exhausted addresses for 192.168.0.1 |
Clients: /etc/portage/repos.conf/gentoo.conf
| Code: |
[DEFAULT]
main-repo = gentoo
[gentoo]
location = /var/db/repos/gentoo
sync-type = rsync
#sync-uri = rsync://MasterTux/gentoo-portage <---Using this gives "!!! Exhausted all addresses for Mastertux"
sync-uri = rsync://192.168.0.1/gentoo-portage <---Using this gives above error
auto-sync = yes |
Servers: /etc/rsyncd.conf | Code: |
# Minimal configuration file for rsync daemon
# See rsync(1) and rsyncd.conf(5) man pages for help
# This line is required by the /etc/init.d/rsyncd script
pid file = /run/rsyncd.pid
use chroot = yes
read only = yes
address= 192.168.0.1
# Simple example for enabling your own local rsync server
[gentoo-portage]
path = /usr/portage
comment = Gentoo Portage tree
exclude = /distfiles /packages |
Can only SSH to "MasterTux" using: | Code: |
ssh someuser@192.168.0.1 |
Attempting to use: | Code: |
ssh someuser@MasterTux |
only results in logging into the client I am attempting to log in from?

Your path is wrong. It should point to /var/db/repos/gentoo
Also, "address" is not needed.
Here is mine :
| Code: |
pid file = /run/rsyncd.pid
use chroot = yes
read only = yes
max connections = 5
uid = nobody
gid = nobody
# Optional: restrict access to some Gentoo boxes
hosts allow = 192.168.10.0/24
hosts deny = *
motd file = /etc/rsync/rsyncd.motd
[gentoo-portage]
path=/var/db/repos/gentoo
comment=Gentoo Repository
exclude=distfiles/ packages/ |
Concerning hostname, i'm not sure, maybe paste /etc/hosts here ? (setup aliases)
My /etc/hosts
| Code: |
# IPv4 and IPv6 localhost aliases
127.0.0.1 destroyer.lan destroyer localhost
::1 destroyer.lan destroyer localhost

You are right about that. I had just caught it before I had a change to check back hear. Syncing is working again... 
As for ssh I did add the server to the hosts file, something I have never had to do in the past. However it did solve my ssh issue. | Code: |
127.0.0.1 SuperTux.homeland.net SuperTux localhost
::1 localhost
192.168.0.1 MasterTux.homeland.net MasterTux |
I still don't understand why this would be necessary. I thought dnsmasq's dns would solve the issue.
