Hi all
This thread has gotten pretty long over the last 2 years. I read 20ish pages of the 25 and received my new SSA3021 yesterday and profiled a couple of bandpass filters to get familiar with options and functionality/use.
I thought I was ready to mod and familiar with many OS's, so I set out to perform the mod and now telnet connections are refused. Thought I would try telnet/ssl, ssh1 and ssh2 thinking they may have locked down telnet and running an ssh daemon, but no luck.
My device is :
Model SSA3021X
SW1 1.2.9.2.a
SW2 20180708-1
SW3 000000E1
HW 0C.03.00
EMI, AMK and Refl are temporarily enabled for 44 hours remaining and TG permanently enabled
I intended to perform the following:
Part 1 - Backup files
1. Insert USB stick
2. Go in System => System info
3. Establish a telnet session with root/ding1234
4. cp -R /usr/bin/siglent/usr/backup /usr/bin/siglent/usr/mass_storage/U-disk0/SA-backup
5. cp -R /usr/bin/siglent/firmdata0 /usr/bin/siglent/usr/mass_storage/U-disk0/SA-firmdata0
8. sync
9. logout
Part 2 - Perform hack
1. Establish a telnet session with root/ding1234
2. mv /usr/bin/siglent/firmdata0/NSP_sn_bandwidth.xml /usr/bin/siglent/firmdata0/NSP_sn_bandwidthx.xml
3. mv /usr/bin/siglent/usr/mass_storage/U-disk0/SA-backup/NSP_sn_bandwidth.xml /usr/bin/siglent/usr/mass_storage/U-disk0/SA-backup/NSP_sn_bandwidthx.xml
4. sync
5. logout
6. Soft power cycle (power off and power on with button "power")
7. Go in System => Pwr On/Preset => Reset & Clear => Enter
8. Soft power cycle (power off and power on with button "power")
But I mistaking performed the following instead:
Part 1 - Backup files
1. Insert USB stick
2. Go in System => System info
3. Establish a telnet session with root/ding1234
4. cp -R /usr/bin/siglent/usr/backup /usr/bin/siglent/usr/mass_storage/U-disk0/SA-backup
5. cp -R /usr/bin/siglent/firmdata0 /usr/bin/siglent/usr/mass_storage/U-disk0/SA-firmdata0
8. sync
9. Soft power cycle (power off and power on with button "power") <--
10. Go in System => Pwr On/Preset => Reset & Clear => Enter <--
11. Soft power cycle (power off and power on with button "power") <--
12. logout
Part 2 - Perform hack
1. Establish a telnet session with root/ding1234 <-- Now refusing connections
Please advise if there is anyway I can undo the damage as I'm not able to telnet in anymore. I wonder if performing a factory reset would resolve issue or trash my license and halt all operations.
SSA is still fully functioning, I’m just unable to telnet in and rename the bandwidth files to perform the mod.
Thank you
