The problem is the underlying "protocol" for finding a console. Assume conserver listens on port 782.... CLIENT (console) SERVER (conserver) --------------------------- --------------------------------------- connect to master conserver on port 782 accept connection on port 782 ask for console 'foo' if 'foo' is not local (distributed setup) respond with remote console hostname (console client starts over with new master conserver) else (is local) respond with random high-numbered port connect to conserver on random high-numbered port accept connection on high-numbered port authenticate, chat, etc... --------------------------- --------------------------------------- So, ask you can see, while the first connection is to a known port, the real work is all done with a random high-numbered port (each conserver child process opens it's own randomly-allocated socket) which is passed to the client dynamically. I hope this helped clear up what's going on and show you where the gotchas are. If you come up with a nice way to make the data encrypted, I'd love to hear about it (I and others have been wanting this feature for a long time). Hopefully I or someone will be able to implement encryption bits sometime soon (emphasis on "someone", knowing my schedule).

I'm using a Xyplex/iTouch 1620 terminal server, and am using Xyplexes supplied 'csportd' application to link a port on the term server to a pseudo tty on my host system (running Solaris 8). Running conserver with this setup gives me (eg): conserver: tcgetattr: /usr/local/Console/dev/ogopogo(8): Invalid argument where the named device is a symbolic link to /dev/pts/whatever. I have verified that csportd is allocating a pseudo tty, and have tried configuring conserver to use the tty name directly instead of the link, same error. If I configure conserver to talk to a pseudo tty representing an xterm window, it works fine, so it would appear that my problem is in the way the pseudo tty is being allocated by csportd. Has anyone used csportd before with conserver?

The only thing I can't do is pass break properly. Here's the setup: Xyplex 1620 terminal server, system console connected to one of the serial ports. I can telnet to the port and generate a break by issuing the telnet 'send break' command, so the terminal server end of things is fine. Xyplex's "csportd" application which sets up a pseudo tty that I can talk to directly through conserver. 'csportd' allows setting the break character to anything, I've verified that if I set the break character to some simple string (like '123') I can connect using 'console' and 'conserver', enter '123' and generate a break on the system console, so it looks like csportd is working ok. The default break character is the Telnet break character, or '0xfff3'. And of course conserver, which talks directly to the pseudo tty that csportd sets up. The part of the conserver code I'm going through is using tcsendbreak to generate a break. I don't know much about the termios interface, it appears to me that using tcsendbreak is not causing anything to happen at the csportd side. I am, naively, expecting 'csportd' to see a telnet break character (0xfff3) when reading from the pseudo tty when conserver calls 'tcsendbreak'... Is this truely naive, i.e. should csportd be looking for something different, or ??? Lost at this point... I could, of course, modify conserver to send the telnet break sequence when it sees the break command, but this seems rather silly...

The workstation is explicitly listed by IP# as "trusted", and is in a subnet listed as "allowed". This happens both with 6.1.7 and 7.0.0. "console -q" asks for a Root password, and then returns the same error. Everything's running on x86 Debian Woody or Sid.

I've worked with a site that was using values of 16/96...their biggest issue was the memory requirements of having close to 96 conserver processes on the host. Aside from the lack of encryption on network traffic, this is my second biggest complaint about the software: bad memory management. I won't go into all the details, but each process keeps a full copy of all data. So, going with those values will definately work (assuming you have enough VM). I'd expect that values of 32/64 would work as well. 32 (consoles) * 3 (console,logfile,user) + 8 (stdin,stdout,stderr,other?) === 104 file descriptors per process. That's not too bad (boy, I hope I got that formula right - it's close). By going with 32 per process you'll reduce your overall VM usage as well. Bottom line: 16 per process is a safe bet...I'd be willing to bet 32 per process is ok as well. The process limit shouldn't matter except for VM usage.

Hmmm...I have a RAID array that uses line drawing characters and they pass through just fine (7 or 8 bit compilation setting). Are you logging the data to a file? Does the data in the file look correct? In my logfile it looks like there's a "start line drawing" sequence (ctrl-n), then a bunch of normal characters (m,q,j, etc) and a "stop line drawing" sequence (ctrl-o) (an echo of ctrl-n,mqqqqj,ctrl-o makes line characters appear, actually, so that's probably it). Do things like that being logged? Since all of that are 7-bit characters, it should "just work" through conserver. Whatever conserver gets on the console is logged without change (except for possibly stripping the high bit) to the logfile. > >> Also, is there any info on how keycodes are passed on? > > To amplify, it'd be nice to understand the mechanism well enough to ensure > Fn keys and suchlike are sent properly, and perhaps even to remap > to something like, say, SysRQ (for Linux kernel hackers, y'see). > Also, no matter what the terminal-type is set to in the inittab for getty > on the machine being controlled, backspace and delete don't work when > logging in. Though ^H does. Arrow keys move the cursor but seem to > invisibly mess up the username/password. Oops..forgot to address this question. Conserver and the console client do no translation of characters (in either direction)...it's just a "semi-stupid" conduit between your keyboard and the serial port (well, console - could be a command being run instead of a serial port, ya know). I say semi-stupid because you have all the escape sequences to replay logs, send a break, etc. I'd suggest logging into a console that you're having trouble with, run 'cat -tv' and then hit the backspace and return keys. Do you get a '^H' as output or some long sequence of escape characters (which some things like to send)? It's one way of finding out what, exactly, your keyboard is sending and what the terminal driver is seeing and having to cope with. That should, hopefully, help you determine what you need to do to get it to pass the right data. > And yes, I'm trynta look at the source, too. Good luck! I hope some of what I've said helps. Yell if I made things less clear or anything.
