Network broken after upgrade

F

firetree

Hi all,

I ran the upgrade to 13.2-RELEASE-p11 AMD64 and (not immediately but shortly thereafter) I'm left with a semi-useable system:
1. cannot access internet, ping freebsd.org returns "Unknown host" and freebsd-update cannot find servers;
2. I can ping my router fine;
3. Apache24 runs fine, can access webpages and filesystem via login via browser from remote;
4. Putty won't connect but Windows SSH connects after a minute or so;
5. can access FTP server but takes a minute or so to connect;
6. Windows cannot find Samba shares.

er, confused.

zfs list shows new NAMEs:
zroot/ROOT/13.2-RELEASE-p10_2024-03-28_084651 8K 333G 366G /

I'd like to upgrade to 14.1 but cannot access servers, I have a USB stick with 14.1 install.
I have no idea what to do, I assume that I can use the 14.1 USB to upgrade but how to do this?
Is the situation indicative of some deeper (hardware?) problem maybe?

Any help much appreciated.
 
based on

1. cannot access internet, ping freebsd.org returns "Unknown host" and freebsd-update cannot find servers;
2. I can ping my router fine;

I'd say check your /etc/resolv.conf to make sure you have at least one valid DNS server configured in there.
And then if you have a valid gateway configured

netstat -rn4
 
Yes, can you ping the name server you have in /etc/resolv.conf?
Give us the output of ifconfig and also the content of /etc/rc.conf.
 
Firstly,

many thanks for the swift replies.
All appears to be well now, thanks again for the suggestions, I changed my nameservers to Google's from my ISP's, BT, primary and secondary nameservers.
They don't respond to ping. The issue first happened two weeks ago (have been on different continent than my server)... I must have "missed an email" :- )

old resolv.conf:
nameserver 62.6.40.178
nameserver 62.6.40.162
