You can add additional ingress rules. (port 22 is already whitelisted)
egress is allow-all by default
Yes there is, click through from your instance properties to "Subnet", then to "Public subnet ...........", then to "Default Security List".
Also most ICMP is blocked by default so the instances don't ping, you have to allow ICMP there if you want them to (for monitoring and such).
thx @rm_ Did you find where to set the ptr? closest I can get is "DNS Domain Name: DNS isn’t enabled for this VCN" but I'm not even sure that's the right option to set the FQDN for the public IP
No. Doesn't seem to be any way to set it.
$ sudo virt-what
kvm
so we can reclaim some free space with
and It looks like there's no swap space set as a default.
EDIT: as rm_ wrote, it already defaults to -m 0 so that's not a good idea!
No, it appears to have been set as "-m 0" by default already on mine, and by applying "-m 1" you will actually reduce the available space.
isn't "-m 0" a little too dangerous?
I'm still exploring this cloud service, so I'm just sharing my findings. And you're right that setting "-m 1" the free space decreases, and on a newly created server
To create a persistent 1GB swapfile in the Ubuntu 1804 LTS (there's no Debian template in Oracle Cloud)
swappiness is already set at 60
Has anybody managed to get a working apache or nginx server on this thing (with Ubuntu 1804)?
I've tried both servers, disabled iptables completely (ufw disable), added rules (ingress tcp 80) to Network Security Lists, put Apache/Nginx to listen to local or my assigned 10.xxx IPs or to "*" or to "0.0.0.0".
I can modify Security Lists in order to allow pings and to enable/disable/limit SSH connections but I cannot make it listen and answer to stupid, plain http.
Jesus! I think I am going nuts over this! What obvious shit am I missing?
Maybe you somehow didn't disable them fully? Port 80 also didn't work for me by default, but works after
iptables -I INPUT -p tcp --dport 80 -j ACCEPT
.As for their panel firewall, I just created such rule, both on Ingress and Egress:
on an empty server
sudo iptables -L gives
and in https://docs.cloud.oracle.com/iaas/Content/Compute/References/images.htm
so I guess we need to use iptables to add INPUT rules for services (default to allow only ssh) without deleting other rules
@rm_ @marrco : Thank you, it worked.
Out of host capacity.
Free user can overuse resource?
I don't like suprise invoice.
cannot register while using my credit card...
just dont. the reason free things are no longer free because of abuse.
So, i can't use paid services without upgrade account to paid account?
overuse != abuse.
I think he meant chance of being charged unwillingly for exceeding limits
@JerryHou you can ask their chat
overuse is a polite term for abuse. I'm a creep, i cant be polite.
Depends on where you live, i think they have problem with Southeast Asia people. Maybe its only me, correct me if im wrong. I even used my two debit cards and one credit card. All are declined.
Misuse is a closer term for abuse. Overuse is just excessive use (which can be OK, or OK when paid).
I like use for only legal things.
I worry about unexpected costs.
Example: I start a VM, i got $100 invoice end of month.
AWS typically looks like this.
Open that window and ask their chat (no need to register). Then come back with an answer
Duh.
Chat overloaded currently
Oracle? The company that basically dropped Sparc and all but killed Solaris and that is hardcore commercial?
Sure, what can go wrong becoming a product of theirs...
Paying for what is used should never be "unexpected". Often 'overuse' just means abusing resources you get. Like coin mining on a shared server or running intensive task ot the expense of your node neighbors. I use regular AWS services for years and never had 'unexpected' invoices, all my monthly invoices exactly reflect my use.
Don't start a VM if you don't like paying for what you (over)use.
If you have a doubt that your "use" can be considered 'overusing resources' why don't you buy a dedi so that you can rape your rented hardware 24/7?
Specifications on the Free tier are not really clear.
If I understood it correctly: one can create 2 free VPS's (albeit in the same satacenter) within the always free tier ?
There is an overall limitation of a monthly 10 TB data in/out ? What if one would exceed this limit ?
This much is pretty clear. But I don't think the same-DC limitation is intended, just a side effect of how their limits are currently designed. Did anyone ask them about it, or everyone just staying within one DC only for the free instance? Seems like such a waste since they got so many diverse locations.
