Correct your IPv6 settings and try again. Solution for IPv6Ī common cause is because of wrong IPv6 settings. When I try to ping another box I get a 'Connect: Network is unreachable' message. I am trying to add a route for assign a network interface to the traffic to/from a specific net, but allways to get the same system message : network is unreacheable. I am only able to communicate with the local network (only the local IPs are accessible). Or just wait and mail will start to send. I am running RH7.3 on a compaq presario box. If that fails start a broadcast listener as daemon. I had not configured networking while installing linux, would this cause a problem. Notes: - the net mask reported by IFCONFIG and routing table are different - could this be the problem, how can I fix it. You cant dictate a multihop path through a network from your host you can only tell it the next hop to use, and the. traceroute: sendto: Network is unreachable 1 traceroute: wrote 40 chars, ret -1. If not, change network to use DHCP and try to get an IP. When you use static routing, you need to provide the next hop to the destination, and 1.1.1.35 cant be the next hop from your host, since your host is not on the same network as 1.1.1.35.
If you want to use IPv4 instead, then you should edit the Postfix configuration file: vi /etc/postfix/main.cfĪnd change inet_protocols = all to inet_protocols = ipv4 and restart or reload Postfix: /etc/init.d/postfix reload My suggestions (requiring some work on the Pi that is started upon boot): - Check if network of current config is up. When trying to send email to a gmail account through postfix you can see an error like this in the postfix logs /var/log/maillog : Oct 13 17:49:54 solver postfix/smtp: connect to gmail-smtp-in.l.:25: Network is unreachable Solution for IPv4
