Agilent E7495 linux root account

[Urs42]

I found out i'ts running linux on an ARM CPU, i can't have any Linux Box without root access, so i did some password cracking:

User: guest
Pass: noname

User: root
Pass: wh1skers

You can log in to it with telnet, it has many serial ports, i suspect that most of them are used to communicate with the Spectrum Analyzer Part. The Powerup Config of the Device is stored in /flash/egServer/registry/Powerup/ if you want to change some default settings. There is an ftp client on the device, if you run a ftp server on your computer, you can use it to copy files from and to the device. Binaries from debian woody will work on the Device.

[jwm_]

That is great, time to email them and ask for the source code. Depending on their mood, we may get the source to drivers for their hardware in it.

[Wuerstchenhund]

Nice find! Yes, the E7495 is a nice device, and great for hacking or expanding its capabilities, probably more so than most other VSAs in that price class.

You should be able to get the source code for the OSS stuff from Keysight but I believe the hardware drivers are closed source binaries.

But hey, there's a lot that could potentially be done with that thing. Maybe someone can fix the sometimes temperamental screen capture function, or even modify it so that it works with USB drives as well.

[Urs42]

There is no USB Storage Support in the kernel running on the device, and the module is also missing :-(

The kernel Version that is running on the device is available on the internet, the .config from the kernel would help with building a matching module, i'm not sure if it's possible to build it without the .config.

They are Obligated to give us the source, because of the GPL...

I think that the mounting and unounting of the cf card is done with shell scripts, it should be possible to switch the scripts to USB.

The licensing of options is done with the flexlm license manager, i have no idea how secure this thing is. There are many Options that don't need additional hardware. I think it might be possible to copy licenses from one device to another.

[jwm_]

If it does just communicate with its devices over serial links, it would be easy to interpose a driver to capture and sniff the data. also possible for usb, but a bit trickier if we can't load a kernel module.

can you post its full boot logs, lspci and lsusb?

I was thinking of picking up one of those for use as a general spectrum analyzer, how hampered will i be that it was designed for a specific purpose? Will i always be fighting the UI that keeps on wanting me to repair base stations?

Btw, you can download a firmware upgrade from Keysight and reverse engineer as you like.

Strangely, this device runs some embedded sort of java! xkcd: http://xkcd.com/801/

They took advantage of that, so the PC software they offer simply is the same one that runs on the device, with the difference that it doesn't connect to localhost.

You're wondering why this thing takes so long to boot? This may be part of the answer:

Code: [Select]

# There's some defect in the GUI that results in
# intermittent hangs on startup (very rare, but some
# boxes can hit it regularly). This delay is a workaround
# to avoid them. When the root cause is found and fixed
# this delay can be removed.
sleep 16

I was thinking of picking up one of those for use as a general spectrum analyzer, how hampered will i be that it was designed for a specific purpose?

Not hampered at all. It's a normal Vector SA which covers from 500kHz to 2.5GHz (E7495A)/2.7GHz (E7495B) all the way from zero span to full span.

Also no need to "fight" the menu. You can ignore the BTS specific software and selectr "Spectrum Analyzer" directly in the main menu.

I'm working on a review of my E7495B, with some luck I might finish it this weekend.

[Urs42]

The GUI Part of the Software is java, there is also a server part that is not written in Java. Some parts of the Software are missing in the Firmware update.

The serial port /dev/ttyS/ttySA0 is used for a serial console, and elgato is using ttyS0, ttyS2 and ttyS3. I think ttySA0 and ttySA1 are available on the back of the device.

The java part of the software is using /dev/rpg which is a simlink to /dev/sio15 i'm not sure what this is.

It would be interessting to add some non GSM/UMTS signals to the signal generator,  the data files for the generator are stored in /flash/egServer/Dragonfly/Measurements/Data/ and i have no idea about the format.

It would be interessting to add some non GSM/UMTS signals to the signal generator,  the data files for the generator are stored in /flash/egServer/Dragonfly/Measurements/Data/ and i have no idea about the format.

I guess these are waveform binaries for the built-in Arbitrary Waveform Generator.

If we find out the format then we could create our own and push it to the E7495. Maybe even a function could be added to the Java GUI to enable copying waveforms from/to the CF card and PCMCIA card.

Thinking about it, it would make the E7495 into a really flexible tool.

Hello to all,
 
It is nice to know that someone else is digging out around E7495B software....
Own one unit just couple of months, working just fine, except remote SW on PC with new windows version XP and later.
Therefore I made debug of JAVA code in attempt to write own SW... for PC operated under Linux (Ubuntu 12 and later)
and new Windows versions.

I am interested to join efforts to bring this nice instrument to full use

Here my hardware configuration ->

[9aplus]

Here just for educational evaluation
decompiled Java egclient app...
https://www.dropbox.com/s/waxxkz9c44h7dy2/egclient.src.zip?dl=0

[Urs42]

The remote software consists of two parts egclient.jar and  RemoteGui.jar. egclient.jar is also the GUI that you see on the device itself. RemoteGui.jar is a wrapper around egclient.jar it provides some additional buttons, for example the ESC/Lcl Button that is needed to switch between the local and remote mode. egclient.jar runs just fine on a Debian 7 System, didn't test any Windows version because i don't have one. The problem with running egclient alone, is that you can't press the ESC/Lcl button, so the remote control dons't work :-(

Code: [Select]

java -Dserver=10.10.0.101 -DlocalAddress=micro -classpath "egclient.jar:xerces.jar:JimiProClasses.zip:RemoteGui.jar" elgato.gui.MainWindow
I do have the same options installed.

[9aplus]

Must try than on my Ubuntu 12.04 LTS but so far no luck with j2re-1_4_2-linux-i586.bin from Oracle site....

Here my hardware configuration ->

Nice. I'd love to have options 240 and 245, as well as 230 and 235. My unit only came with CDMA+EV-DO unfortunately.

[9aplus]

Right,
but on the other hand I was not so lucky with SW keys ->

[Urs42]

I'm using the openjdk-6 Package from Debian.

I think you can copy the license file from one device to another if you change the hostid on the target device. But i'm not sure...

[PA0PBZ]

The E7495 firmware looks very much the same as for the N1996 CSA SA, I can even use the remote client on my CSA. The license manager on the CSA is easy to patch so that it accepts any license code, maybe it is the same for the E7495. The license daemon on the CSA is called TORO, but I could not see something simular in the ps output posted above.

[Urs42]

The licensing is done by the elgato process. I think they are using flexlm. Here is the license file from my device, i did remove the HOSTID and SIGN Values.

Code: [Select]

$ cat elgato.lic
FEATURE 200 agilent 1.000 permanent uncounted \
HOSTID=ID_STRING=XXXXX SIGN=YYYYYYYYY
FEATURE 220 agilent 1.000 permanent uncounted \
HOSTID=ID_STRING=XXXXX SIGN=YYYYYYYYY
FEATURE 240 agilent 1.000 permanent uncounted \
HOSTID=ID_STRING=XXXXX SIGN=YYYYYYYYY
FEATURE 245 agilent 1.000 permanent uncounted \
HOSTID=ID_STRING=XXXXX SIGN=YYYYYYYYY
FEATURE 205 agilent 1.000 permanent uncounted HOSTID=ID_STRING=XXXXX \
SIGN=YYYYYYYYY

[PA0PBZ]

I think they are using flexlm.

Yes, that is FlexLM, same as N1996A and E4406A.

[theatrus]

Looks nearly identical to the N1996A.

The good news is the binaries have most of their symbols intact - objdump (for ARM) and search for some likely functions

[9aplus]

Here more luck with OpenJDK Java 6 runtime

Now RemoteGUI.jar is running but not happy with egclient.jar version.
Program is offering download of egclient.jar from E7495B but file
transfer ends with 0 size....


 

[PA0PBZ]

Well. I just downloaded the firmware and did a quick compare between the toro process and the elgato one. Then I did a search for 16 bytes around the patch area and elgato had only one hit. So for whoever feels lucky, try this: (latest firmware downloaded from HP Agilent Keysight site)

Elgato offset 337A7C, change 01 00 00 EA to 00 00 A0 E1.

Then check your license file if there are any entries without the SIGN = part, because they start to work magically if the patch works and you don't want any weird options enabled. Just take them out.

Good luck and let me know 

Edit: Version A06.25

[Urs42]

Many thanks PA0PBZ, i'll try that.

toroServer looks alot like egServer. It would be interessting to see how similar the hardware of both devices is. FM/AM Demodulation and other Stuff i see in the toroServer directory would be cool...

[PA0PBZ]

toroServer looks alot like egServer.

It does, I even see a lot of possible options in the CSA that looks to be for the E7495:
