Using Medley with Dodo

[pamoroso]

According to the documentation on using Dodo with Maiko:

As long as Dodo-networking support is not merged into the master-branch of the primary Maiko repository, this networking option is only available in this clone of the original Maiko repository in the branch dodo-nethub-support.
(however: this branch should already be checked out if this file is present)

There doesn't seem to be such a branch in the primary Maiko repo:

paolo@lispmachine:~/medley/maiko$ git checkout dodo-nethub-support
error: pathspec 'dodo-nethub-support' did not match any file(s) known to git

The only Dodo-related branch I can find is fgh_nethub-build. Where is the Maiko branch or clone with Dodo support?

[nbriggs]

That document is out-of-date, but not worth fixing to reflect the current master branch setup, since the nhb-pcap-ethernet changes the way the network implementation is selected. But this document should get updated in that branch. Not sure if I can get to it soon though. Compile on the nhb-pca--ethernet branch with `./makeright x NETWORK=NETHUB" (after the appropriate cleans). init does NOT require the network. sdl can use the network. Then the --nh-whatever options work as they used to.

[pamoroso]

Okay thanks. Do I still need to run setcap on ldex?

[nbriggs]

setcap is not required for dodo networking because in that case ldex is just talking over a regular TCP stream to the dodo hub. When using the raw ethernet interface you do need setcap because unprivileged programs are not generally allowed to send arbitrary etherpackets.

[pamoroso]

After setting up Dodo as @nbriggs explained I loaded Lafite and LAFITE-NEWNSMAIL and... it works!

[nbriggs]

Excellent.

[pamoroso]

I have the Dodo dependencies installed and I'm trying to run NetHubGateway but I get this error, presumably because the ; trips the shell:

paolo@lispmachine:~/medley/dodo-xns-services$ java -cp dodoserver-and-nethub.jar;jnetpcap.jar dev.hawala.hub.NetHubGateway
Usage: java [options] <mainclass> [args...]

           (to execute a single source-file program)

[...]

bash: /home/paolo/medley/dodo-xns-services/jnetpcap.jar: No such file or directory

Enclosing the classpath in quotes doesn't work either:

paolo@lispmachine:~/medley/dodo-xns-services$ java -cp "dodoserver-and-nethub.jar;jnetpcap.jar" dev.hawala.hub.NetHubGateway
Error: Could not find or load main class dev.hawala.hub.NetHubGateway
Caused by: java.lang.ClassNotFoundException: dev.hawala.hub.NetHubGateway

I think my classpath is fine:

paolo@lispmachine:~/medley/dodo-xns-services$ echo $CLASSPATH
/home/paolo/medley/dodo-xns-services:/home/paolo/apps/jnetpcap-1.4.r1425:

[nbriggs]

I suspect the -cp option takes a colon rather than a semicolon.

[pamoroso]

Replacing the semicolon with a colon doesn't seem to help:

paolo@lispmachine:~/medley/dodo-xns-services$ java -cp dodoserver-and-nethub.jar:jnetpcap.jar dev.hawala.hub.NetHubGateway -ldd -lhd
Error: Unable to initialize main class dev.hawala.hub.NetHubGateway
Caused by: java.lang.NoClassDefFoundError: org/jnetpcap/packet/PcapPacketHandler

[pamoroso]

There was an issue with the command line as I copied it from the Dodo script run-nethubgateway.cmd which, being for Windows, included spurious ^Ms. But even with the ^Ms removed I still get the error:

paolo@lispmachine:~/medley/dodo-xns-services$ java -cp dodoserver-and-nethub.jar:jnetpcap.jar dev.hawala.hub.NetHubGateway -ldd -lhd
Error: Unable to initialize main class dev.hawala.hub.NetHubGateway
Caused by: java.lang.NoClassDefFoundError: org/jnetpcap/packet/PcapPacketHandler

@hjellinek Any idea what's wrong with the Java invocation?

[hjellinek]

@pamoroso, perhaps I can help. First, the delimiter for the items in the -cp value is the colon character on Unix/Linux and semicolon on Windows, just like PATH requires.

The values in the -cp value (dodoserver-and-nethub.jar, jnetpcap.jar) refer to files with those exact names. I don't know what's in your current directory, but if it doesn't contain the files dodoserver-and-nethub.jar and jnetpcap.jar, you must edit the -cp value to point to the correct directory, e.g., ../jars/dodoserver-and-nethub.jar:../jars/jnetpcap.jar.

You can run java with the -verbose:class option to display the classes it loads, but since you're not successfully loading the class org/jnetpcap/packet/PcapPacketHandler, this is probably not going to do you much good.

[pamoroso]

Okay thanks, that clarifies things.

dodoserver-and-nethub.jar is indeed in the directory I execute the command from but jnetpcap.jar is in a different one specified in CLASSPATH and that's apparently not enough:

paolo@lispmachine:~/medley/dodo-xns-services$ echo $CLASSPATH
/home/paolo/medley/dodo-xns-services:/home/paolo/apps/jnetpcap-1.4.r1425:

Specifying the full path of jnetpcap.jar does start the Java program which, however, immediately aborts with a different error:

paolo@lispmachine:~/medley/dodo-xns-services$ java -cp dodoserver-and-nethub.jar:/home/paolo/apps/jnetpcap-1.4.r1425/jnetpcap.jar dev.hawala.hub.NetHubGateway -ldd -lhd
## ifName 'MS LoopBack Driver' not found, aborting

Is this related to Dodo itself or jNetPcap? I think both are properly installed.

[pamoroso]

One thing to note is I execute the command after starting NetHub and Dodo Services.

[nbriggs]

I believe that the old jnetpcap code doesn’t work anywhere but windows. The guy who wrote the old version that dodo depends on wasn’t interested in helping with old code and the dodo guy wasn’t interested in porting to the new api for new jnetpcap.

[pamoroso]

I see, that looks like a showstopper.

[nbriggs]

On my todo list is to gateway raw XNS packets in/out of dodo. I already have pcap code to handle xns pup host requests so extending it to a full gateway should be pretty easy.

[pamoroso]

@rmkaplan Now that networking is working again for me I did the test you suggested. I created a pseuduhost on Dodo's first file server {FS1:}, opened a file there, wrote a string to the file, and tried to close the file. Writing to the file failed with the error:

ARG NOT SPPCON
NIL

Calling (CLOSEF S) yielded the same error. I saved the session to a dribble file which contains complete garbage when opened in a text editor, I wonder what the external format was: PHTEST.DRIB.TXT

Anyway this screenshot shows the full session:

Executing the same commands with no pseudohosts, i.e. supplying the file name as {FS1:}<public>PHTEST, works as expected with no errors.

[pamoroso]

I'm reasonably sure Dodo was running but Medley probably hadn't found the Clearinghouse yet. This new test worked as expected:

[nbriggs]

The (START.CLEARINGHOUSE T) shouldn't be necessary - that will happen automatically when you call (LOOKUP.NS.SERVER xxx) as in:

Is the problem you're seeing reproducible?

[pamoroso]

No, the problem is not reproducible. I've just tested by calling (LOOKUP.NS.SERVER "LISPMACHINE1:") without a prior call to (START.CLEARINGHOUSE T) and it works fine.

I'll keep my eyes open and capture a backtrace if it happens again.

[pamoroso]

I've just ran into an anomaly when opening a file browser on the file server {FS1:} to test XIPTRACE. I got a break window with the message Help! SPP Partner acked a packet I haven't sent yet 1, apparently while looking for a Clearinghouse:

Dodo was running and the Medley instance printed the message nh[0]: connectToHub() - connected to nethub.

[pamoroso]

The issue is reproducible.

[pamoroso]

I opened a proper issue: #2702.

[pamoroso]

I configured the Dodo print service as per the documentation. That is, I edited the printService.* entries of dodo.properties and copied to Dodo the indicated files from GlobalView 2.1 for Windows. Starting Dodo confirmed the print service was running:

####### Printing3, supported paperSizes: a4, usLetter
####### Printing3, using ip-to-ps proc: ./prt-poseidon/res/IPPROC.PS
####### Printing3, patched ip-to-ps proc for Xerox PS font usage
####### Printing3, using ps post-processor: ./prt-poseidon/res/postprocess-ps.sh

I printed the file lispusers/BITMAPFNS.TEDIT to Dodo's Interpress print server POSEIDON: with Hardcopy > To a printer > Other... > POSEIDON: and got the error:

Am I going through the correct steps to print to an Interpress printer? How can I troubleshoot the issue?

[rmkaplan]

A first problem is that the variable INTERPRESSFONTDIRECTORIES isn't initialized properly, I see it as {DSK} instead of (currently) {MEDLEY}/fonts/ipfonts. The entry is missing from MEDLEY-INIT-VARS, so it can't find any Interpress font metrics. But after fixing that, I get a stack overflow in the fontcreate. So there is more to do just to create an Interpress file, let alone send it to a dodo printer. In your example, did you just use the Hardcopy menu item on the Tedit window to specify that you wanted an IP file?

Actually, on the font directory, the problem wasn't in MEDLEYDIR, it was a bogus entry for SYSTEMINITVARS in INTERPRESS that was wiping out the intended setting.

Yes, I did use the hardcopy menu item of TEdit: Hardcopy > To a printer > Other... > POSEIDON:. Is there anything I need to do to get Interpress output?

[rmkaplan]

That's the way it is supposed to work, once the fonts are resolved. But there was never a testing path for this, so we may discover some other issues. I think the font stack overflow is a mixup between old interpress metric files and medleyfont files, which I didn't bother to create.

I noticed something unexpected with FINGER. To examine the data of FINGER requests in function SEND.FINGER.REQUEST I inserted a call to HELP just after (SETQ RESPONSES ...) and called FINGER which yielded the error:

UNBOUND-VARIABLE
In OLDFAULT1:
\XIPOVLEN is an unbound variable.

The issue, which is reproducible, occurs also when inserting a call to HELP in function FINGER as the first form of the body of LET.

What's going on? Is SEdit corrupting code?

[nbriggs]

It needs exports.all loaded and I think what I see is no socket at destination messages.

[pamoroso]

I get the error also with EXPORTS.ALL loaded. To run FINGER I used to load SYSEDIT, doesn't that load EXPORTS.ALL too?

[nbriggs]

Ah, it's not an "exported" constant -- load LLNSDECLS.LCOM

[pamoroso]

Loading LLNSDECLS.LCOM resolves the issue.
