Hello! I am xpenology user. And I am an IT engineer who creates shell scripts as hobbies. Please understand that it is written by a google translate site. because i’m korean who is not fluent in English. I created a tool to change cpu information for Xpenology’s users. Modify the actual cpu name and cores of your pc or server. Howto Run ============================================================= 1. Download attached file on your PC (ch_cpuinfo_en.tar) / (ch_cpuinfo_kr.tar is file for korean) 2. Upload file to your DSM location (by filestation, sftp, webdav etc....) 3. Connect to ssh by admin account. (dsm > control panel > terminal & snmp > terminal > enable ssh check) 4. Switch user to root: sudo su - (input admin password) 5. Change directory to where ch_cpuinfo_en.tar file is located: cd /volume1/temp 6. Decompress file & check file: tar xvf ch_cpuinfo_en.tar ls -lrt (check root’s run auth) 7. Run to Binary file ./ch_cpuinfo 8. When you execute it, proceed according to the description that is output. 9. Check your DSM’s CPU name, CPU cores at “information center” ==================================================== Addtional, Adjust binary to excute file made by shc(http://www.datsi.fi.upm.es/~frosal) The tool does not inclue worms, bad code. If you want to edit the CPU information yourself manually, please refer to the contents below. ——————————————————————————————————————————————————————————————— Location : /usr/syno/synoman/webman/modules/AdminCenter Source : admin_center.js / admin_center.js.gz(above 6.2) Add Before -> if(Ext.isDefined(f.cpu_vendor)&&Ext.isDefined(f.cpu_family)&&Ext.isDefined(f.cpu_series)){ o.push([_T("status","cpu_model_name"),String.format("{0} {1} {2}",f.cpu_vendor,f.cpu_family,f.cpu_series)])} if(Ext.isDefined(f.cpu_cores)){o.push([_T("status","cpu_cores"),f.cpu_cores])} Add contents: f.cpu_vendor="Intel";f.cpu_family="Xeon";f.cpu_series="E3-1230 V2";f.cpu_cores="1"; ——————————————————————————————————————————————————————————————— Finally, All descriptions are based on version 6.2, and the actual executable file supports both 5.x and 6.x. Please contact me by comment or bug report, i’ll respond to you as much as possible within my ability. Test & Made Environment ———————————————————————————————————— Base Server : HP Microserver gen8 + VMware ESXi 6.0 + RDM DSM : 6.2-23739 Update 2 (DS3615xs/DS3617xs) 6.1-15284 Update 2 (DS3615xs) ———————————————————————————————————— Thank you!! Have a nice day!! ============================================= Update new version 2018.08.26 I made the tool by adding and improving the function. Please refer to above for how to use it. I delete the old version attached files, new version uploaded and attached. If you use last version tool, you can use without restore. Additional,  It does not yet apply to "mobile web" and "DS finders". it's working.... and... Polanskiman give editable permission to me. so, i can do first article.. thanks Polanskiman !!! ============================================================================ Update new version (ch_cpuinfo ver 4.0) 2018.09.13 1. Mobile support (just 6.x / not yet 5.x) You can see it when you go into mobile browser or "DS mobile" menu in "DS Finder" 2. Improved CPU information collection command Some dmidecode commands have been found to be missing information and have been improved.(Thanks stefauresi !!! ) 3. Edited some variable names I adjusted some inconsistently coded variables Addtional, Usage is the same as before. and Existing users can apply by "2) Rerun". Unfortunately, DS Finder's own app does not reflect system information. It seems to refer to other information and it seems to have to study more. I checked as much as I could ... There may be errors found. Let me know in that time and I will reflect it If you want to edit the CPU information yourself manually, please refer to the contents below. ——————————————————————————————————————————————————————————————— Location : /usr/syno/synoman/mobile/ui (6.x), /usr/syno/synoman/webman/mapp(not yet 5.x) Source : mobile.js / mobile.js.gz(above 6.2) {name: "model",label: _T("common", "ds_model")}, -> Add Back Add Contents: {name: "cpu_series",renderer: function(value){var cpu_vendor="Intel";var cpu_family="Xeon";var cpu_series="E3-1230 V2";var cpu_cores="1"; return Ext.String.format('{0} {1} {2} ({3}Core)', cpu_vendor, cpu_family, cpu_series, cpu_cores);},label: _T("status", "cpu_model_name")}, ——————————————————————————————————————————————————————————————— Reference images 1) First run 2) Redi 3) Restore 4) Mobile View Download files ch_cpuinfo ver 1.0 - delete -> ch_cpuinfo_en.tar -> ch_cpuinfo_ko.tar ch_cpuinfo ver 3.0 - delete -> ch_cpuinfo_en.tar -> ch_cpuinfo_ko.tar ch_cpuinfo ver 4.0 - update new version -> ch_cpuinfo_en.tar -> ch_cpuinfo_ko.tar

GeoIP Region Blocking using Synology Firewall I noticed internet performance issues today and was checking my router logs, I found excessive logs showing: Jun 18 20:55:48 dropbear[5405]: Child connection from <My Synology IP>:40894 Jun 18 20:55:49 dropbear[5405]: Exit before auth: Exited normally Jun 18 20:55:49 dropbear[5411]: Child connection from <My Synology IP>:40896 Jun 18 20:55:51 dropbear[5411]: Exit before auth: Exited normally I searched and found it was related to numerous invalid login attempts to the synology login page. This lead me to login to the cli of my synology and check logs for failed attempts. When checking the logs I found the most concerning log was /var/log/httpd/apache22-error_log 2018-06-18T19:28:42-06:00 nas [Mon Jun 18 19:28:42 2018] [error] [client 193.106.30.99] File does not exist: /var/services/web/wp-rdf.php 2018-06-18T20:11:16-06:00 nas [Mon Jun 18 20:11:16 2018] [error] [client 27.29.158.10] script not found or unable to stat: /var/services/web/login.cgi 2018-06-18T21:51:26-06:00 nas [Mon Jun 18 21:51:26 2018] [error] [client 172.18.0.2] File does not exist: /var/services/web/apple-touch-icon-precomposed.png 2018-06-18T21:51:26-06:00 nas [Mon Jun 18 21:51:26 2018] [error] [client 172.18.0.2] File does not exist: /var/services/web/apple-touch-icon.png 2018-06-18T21:51:26-06:00 nas [Mon Jun 18 21:51:26 2018] [error] [client 172.18.0.2] File does not exist: /var/services/web/apple-touch-icon-precomposed.png This lead me to consider blocking all geographical regions except my own. Most brute force attempts and vulnerability attacks are outside of my home country, this will reduce the attack surface significantly. My first attempt at implementing the geoip blocking was problematic, I attempted a "deny all" entry after the "allow local network range" and "allow my region" rules, but this ended up blocking all access to the services I had running. I thought I'd share how I implemented it for others wanting to reduce the surface area for attacks. Enable firewall Open Control Panel Select Connectivity -> Security Go to Firewall tab Check Enable firewall Add "Allow" Rules for internal network Select Edit Rules for the default Firewall Profile (Disregard existing rules in screen shot, these will be created in the following steps) Create rule to allow your internal/home network Add "Allow" Rules for your country/countries Create rule to allow specific locations Set network interface to deny if rules are not matched Select the network interface that is default to your synology (mine is LAN 1, you can find your interface under Connectivity -> Network -> Network Interface) ***This was the secret to getting the deny all after the allow rules to work*** Set "if no rules were matched: Deny Access" Click OK and Apply Test reaching your synology on your internal network and from external networks in your region. You can also validate if the firewall is blocking by using a Tor browser to send traffic from a different country to see if your firewall rules are working properly.
