I accidentally modified NetworkManager with the command.

nmcli con modify eno1 ipv4.dns-options 'single-request-reopen timeout:2 ndots:0'

I think the modification hasn't been activated since I haven't restarted the device.

I don't know the previous value of the setting.

How can I undo the modification to the previous one?

I set up a couple of maraidb v10.2.10 containers with the official docker image. Master can read/write and slave is read-only with this my.cnf.

[mysqld]
server_id=2
read_only=1
innodb_read_only=1

Replication was working well for a while but it stopped with the following error:

Slave_IO_Running: Yes
Slave_SQL_Running: No
Last_Errno: 1942
Last_Error: Error during COMMIT: failed to update GTID state in mysql.gtid_slave_pos: 1036: Table 'gtid_slave_pos' is read only

I added this line into slave's my.cnf and set it up again from the beginning but still got the same error.

replicate-ignore-table=mysql.gtid_slave_pos

Does this mean that Innodb can't replicate to innodb-read-only server?

I have a .pac file like below.

if (dnsDomainIs(host, ".example.com")) {
    hostip = dnsResolve(host);
    if (isInNet(hostip, "202.0.0.0", "255.255.255.0")) {
        return "DIRECT";
    }
}

Now I'd like to convert this into squid.conf.

A client wants to access to example.com whose IP address would be changed everyday. If the destination IP is in the range 202.0.0.0/24, I need to change the proxy routing(Direct, proxy-A, proxy-B and so on).

I know how to change the proxies with squid.conf but I don't know how to define the access which would access into the IP range from just a domain name. I think squid knows only the destination domain name.

If the client accesses with IP, I can distinguish it. Though if the client accesses with a domain name, I can't.

Does anybody know a squid option for this?
