[!Cheyenne] Discussions about the Cheyenne Web Server
| older newer | first last |
| Dockimbel 30-Dec-2008 [3579] | A config file, but if you don't provide one, Cheyenne will create a default one in the same folder. |
| Graham 30-Dec-2008 [3580] | Thanks |
| Graham 31-Dec-2008 [3581x4] | This is interesting. I'm launching cheyenne on startup each time my app starts. But to see if it is already running, I check by opening a port. p: open/direct tcp://127.0.0.1:8002 close p but this causes Cheyenne ( latest encapped version ) to shut down! |
I tested this with the above and a rebol console to reproduce it. | |
I guess I should check with read http://127.0.0.1:8002 instead, but that's slower. | |
but does it mean I can crash any Cheyenne server remotely at will? | |
| Henrik 31-Dec-2008 [3585x3] | Graham, try mine and let's see what happens. |
although I still am running an older version... | |
I have to go for a bit... | |
| Graham 31-Dec-2008 [3588x3] | Oops .. changed this group to non web public ...shouldn't have posted this is a web public group |
No, it's okay with yours. I'm guessing it only crashes on localhost. | |
phew! | |
| Will 31-Dec-2008 [3591] | Graham, do you have any custom services? no problem here with that code: p: open/direct tcp://127.0.0.1:80 close p p: open/direct tcp://127.0.0.1:80 close p p: open/direct tcp://127.0.0.1:80 close p p: open/direct tcp://127.0.0.1:80 close p p: open/direct tcp://127.0.0.1:80 close p read http://127.0.0.1:80 ; {<html> <head> ^-<title>Welcome!</title> </head> <body> <img src="logo.png"> <center> <h2>Congratulations, you are running Cheye... |
| Graham 31-Dec-2008 [3592] | this is just the Cheyenne binary ... nothing else, and running on 8002 |
| Will 31-Dec-2008 [3593] | hmmm, I'm running from source |
| Graham 31-Dec-2008 [3594x3] | >> p: open/direct tcp://localhost:8002 close p p: open/direct tcp://localhost:8002 print "ok" close p ** Access Error: Cannot connect to localhost ** Near: p: open/direct tcp://localhost:8002 print "ok" >> |
the ok does not print because Cheyenne has quit | |
this though is fine >> p: open/direct tcp://localhost:8002 print "ok" close p p: open/direct tcp://localhost:8002 print "ok" close p ok ok so timing appears critical | |
| Henrik 31-Dec-2008 [3597x2] | Graham, I have to check my console, because I think mine auto-restarts on quit. |
seems there is nothing in consle | |
| Graham 31-Dec-2008 [3599] | meaning? |
| Henrik 31-Dec-2008 [3600] | meaning it didn't quit |
| Graham 31-Dec-2008 [3601x3] | ok |
well, reproducible on my system. | |
I guess we can make this group web-public again. | |
| Will 31-Dec-2008 [3604x4] | keep it non public, there is a wiki on cheyenneserver.org for open web |
btw Henrik and I are running it on osx | |

maybe someone is attaking you http://ftp.uni-kl.de/25C3/video_h264_720x576/25c3-2909-en-tcp_denial_of_service_vulnerabilities.mp4 8P | |
| BrianH 31-Dec-2008 [3608x2] | Please let us know if there are any security vulnerabilities that pop up for Cheyenne, or REBOL network services for that matter. |
I am about to use Cheyenne for a project that I have just found out will be more public than anticipated., | |
| Dockimbel 31-Dec-2008 [3610] | Graham: no problem here, testing with 0.9.18 binaries and 0.9.19 source version, can't reproduce that crash (all tests done on port 80). WinXP-Pro-SP3 here. |
| Graham 31-Dec-2008 [3611] | I'm on vista and using port 8002 |
| Dockimbel 31-Dec-2008 [3612x2] | Do the Cheyenne processes disappear when your test fails? If not, did you try to access a web page to see if it's still responding? |
try => tried | |
| Graham 31-Dec-2008 [3614x3] | I'm watching the task manager ... all 3 cheynne processes quit |
I think timing is critical for this bug to appear | |
ie. if I add a print between the open and close, the bug does not appear | |
| Dockimbel 31-Dec-2008 [3617] | I'm trying here with the code you've posted (without the print), but can't reproduce. |
| Graham 31-Dec-2008 [3618x3] | Hang on ... |
http://screencast.com/t/cPpSejdtYZ | |
watch the task manager | |
| Dockimbel 31-Dec-2008 [3621x2] | Could you please try with the source version (v0.9.18) from here : http://cheyenne-server.org/dl/cheyenne-r0918.zip? |
Btw, did you checked for a %crash.log file near cheyenne.exe? | |
| Graham 31-Dec-2008 [3623x4] | ok. dl now |

does that help? | |
forgot about crash.log | |
| Dockimbel 31-Dec-2008 [3627] | Ah, interesting. |
| Graham 31-Dec-2008 [3628] | still want me to test with source? |
