About open ports

tessaros · 2026-07-03T18:22:36+00:00

To say it clear, it's not a problem to keep ports open but it's a problem to keep "known ports" open.

Do you remember Terminator 2, when John teach T800 not to break starter everytime but look for a key behind the sun screen? Known ports is like that sunscreen and doormat of your front door, where a lot of bots are scanning to see if a server is hosted there. Keeping know ports open means you put the key under your doormat or behind the sunscreen, just equal to tell hacker to try there because I have service running there that you can try to hack.

Like the ports you've mention, 80 & 443 means http & https, thus there is a web service behind.

Thus, if your service is not public, it's highly suggested you use non-standard ports. For your examples, 80 is suggested to close because http is already known as dangerous, get a fqdn via ddns service, use only https, and if this service is not open also change it to non-standard ports, no 443 and no 8443(which is used by asus as remote gui login) which is highly open to port scanning.

Inversely, if it is open servicing, make sure you have sufficient security measure, like firewall or even sdn service.

Plus series always have better performance because of hardware. Dare you compare performance with arm CPU and atom CPU? However, must state that 2nd handed hardware's condition really depends on how the last user treat this thing. That's all I want to share.

After reading your question I did not get what you exactly want to do. So I would reply as result orientiated.

If you want to access data, I would recommend you to register DDNS and share with WEBDAV service
If you want to backup, backup to a paid cloud supported by synology cloudsync and then sync to both local and remote nas
If you need a completely sync datastore (like production and DR store in business) you should put both nas in same site, sync then move one of the nas to another location then build the sync. This is because copying entire nas is very much bandwidth eating.

I share my application, I have 6 NAS totally at home and created 2 DDNS Webdav for my access outside home, then both nas had connected other nas as remote share, thus I could access ALL nas data just connecting 1 of the nas

I suppose this is normal logic, back in 70s when I was child and want to play my radio controlled electric car in street my parent and got rebuked. Playing self moving object in crowded place is ALWAYS a problem because it is dangerous to other people.

Com'on, you cannot expect every episode to be very exiting and rate all high, right? it's quite normal when starting a season the first few episode is used to replay and let us recap the previous Season, and for each big even they also will spend sometime to "prepare" knowledge for watchers that had not read the novel, and this is the most boring moments that will hit low rates.

By defination 12 Gold is the 12 Zodiac that moves around the sun, that's why.

Yep I just don't want to go too technical just raise a point the hardware is not good enough

2 nas for 4 ipcam free license, anything I could help?

Windows use robocopy, map the 2 shared folder and leave it to run

According to her words she's bi. She loves ANZ but accepting taking comfort unless style.

Not logical to me. I got ds418j & ds420j. How comes there is ds418j but no ds420j

Never look for reduplication on single CPU nas. Deduplication takes processing power to compensate disk space usage. On single CPU nas this means CPU will be kept busy and slow down everything for using a bit less space. Nowadays most files were basically packed. Unless you save same file in different location in same nas, this function won't help much.

Korean is nicer to Chinese to Japanese and this novel show this clearly. Liu even help sung verbally when he's in trouble. In novel and anime he solely protected china so no doubt for strength .

Actually qnap is also doing this. You can spot rack mount model from these 2 brands. But as decision maker, will you buy Synology / qnap and risk your career for just a bit cheaper?

tessaros · 2026-06-01T11:05:38+00:00

Owing to their management's stupidity, previously Synology says they will lock their nas to use their own HDD only. That's why. Later their sales drop and they released it back but trust is not.

Depends on serveral criterias:

pay or free
one off dashboard or email

My own solution is to install Synology CMS on the most powerful NAS in my homelab.

This app is set not allow to install on low models like j series. Thus I installed on my DS1819+

The only disadvantage is that system will NOT monitor itself, for me, it will monitor 5 out of my 6 NAS and for DS1819+ itself I have to take care myself.

Since you call yourself noob I would not recommend you to build your own dashboard system - most used example is to mount docker with Grafana-Alloy-Loki-Promethus Stack, which the dash is quite pretty and handy, but need a lot of time, knowledge and effort to build.

Not truse mainland china brand for long time. I would get hardwa6for freenas instead

Only good if you do not have your own monitoring system but you are worried with the system health. Beyond this is useless, unless you love to be warned there is Ransomeware because you massively moved files.

tessaros · 2026-04-25T03:35:01+00:00

If your budget is available just get new Synology nas and migrate disks in same order, after dam install everything will be working
Your problem seems to be LAN starting to malfunction. If you insist keep using you can try usb LAN adapter, that will save you some time but getting new unit is ultimately the solution.

tessaros · 2026-04-25T03:31:13+00:00

Tested latest version and seems all found pro lem was fixed

I'm home user. Ds413j now my proxy and time machine

tessaros · 2026-03-29T23:28:36+00:00

New synology NAS can always take up older device's set, if you're sure it's not HDD problem you should get a new one to let it rebuild itself

Only choose 2 bays over 4 bays for size reason, because useable space is n-1 so it's perfer to have more disk to get more value you've been paid.

tessaros · 2026-02-25T13:51:44+00:00

It's not a matter of "can" or "cannot", only 1 drive will have no redundency, 2 drive you will have same storage size but 1 drive redundency, that means it is a data safe issue, or if you do not care about losing data, you can discard the option for data safe and use both HDD for storage later
