| Vladimir 2-Nov-2008 [827x4] | only problem is router.... without it if I connect directly PC with WAN connection... rebol scripts work... I connect router on wan and pc on lan port and only rebol script doesnt work... filezilla, total commander, ftp command from windows works... |
I know (at least I thought I knew... :( ) how to set up network and routers... I did this hundreds of times, and had problems with altme, torrent downloaders, games and many others... and solved them.... I tried to add ftp ports, and even whole range from 0-65535 to NAT routing tables.... tried to put whole lan ip range into dmz... Ill try tomorrow.... | |
While Im at this... Does anyone know how ftp works from rebol ? | |
Details about ftp imlementation in rebol ? | |
| Pavel 2-Nov-2008 [831x2] | Vladimir look at rebol.org script folder. there you can find a lot of solution/inspiration |
also rebol.com documentation tutorial and examples especially rebol cookbook | |
| Graham 2-Nov-2008 [833] | the source to ftp is available |
| Pekr 2-Nov-2008 [834] | Vladimir - you still probably did not tell us, what REBOL version do you use? |
| Vladimir 2-Nov-2008 [835x2] | I use 2.7.6 on windows. |
@Graham: Where is the source available? I thought maybe by looking into source and comparing it with the messages I get from net stats I could find more about my problem.... In the meantime I'll try tomorrow to open router completely... all the ports all the ip addresses... and see what happens. | |
| Graham 2-Nov-2008 [837] | probe system/schemes/ftp |
| Vladimir 4-Nov-2008 [838x4] | here is something new.... I tried few things from windows command line. here are two scripts and two logs: 1. script binary cd apl put c:\slanje\zip\ik104test.zip quit 1.log ...... 230-User visaprom.com has group access to: www 230 OK. Current restricted directory is / ftp> binary 200 TYPE is now 8-bit binary ftp> cd apl 250 OK. Current directory is /apl ftp> put c:\slanje\zip\ik104test.zip 200 PORT command successful 425 Could not open data connection to port 35370: Operation timed out ftp> quit 221-Goodbye. You uploaded 0 and downloaded 0 kbytes. 221 Logout. |
2.script LITERAL PASV cd apl put c:\slanje\zip\ik104test.zip quit 2.log ..... 230-User visaprom.com has group access to: www 230 OK. Current restricted directory is / ftp> LITERAL PASV 227 Entering Passive Mode (194,9,94,127,234,131) ftp> cd apl Connection closed by remote host. ftp> put c:\slanje\zip\ik104test.zip Not connected. ftp> quit | |
basicly if I enter Binary mode, upload fails and it looks like it has to do something with port above 35000 problem. If I enter passive mode nothing works.... it always responds with network timeout.... | |
And once more..... total commander works :) | |
| Graham 4-Nov-2008 [842] | well, in this case, you should use wireshark and do a tcp trace |
| Vladimir 4-Nov-2008 [843x3] | Im trying..... will report |
here is command with error: to-port: open/binary/new/direct server/:file ** Access Error: Network timeout ** Where: confirm ** Near: to-port: open/binary/new/direct server/:file | |
and here are log files from wireshark: http://www.visaprom.com/wiresharklog.txt http://www.visaprom.com/wiresharklog details.txt If anyone has little time to read thru them and can tell me something I would appriciate it very much :) | |
| Graham 4-Nov-2008 [846] | what I normally do is click on the relevant tcp lines, and the right click, and then choose "follow tcp stream" so that I only get the relevant data. |
| DideC 4-Nov-2008 [847] | It seems the problem is after the PORT command. It define the port used to receive or send the file data (depending the command you issue). Use Wireshark to have a look to what Total commander do regarding its PORT command. So we can compare with the Rebol commands. I guess the router firewall block the one Rebol use, but Total commander do it in an over way. |

| Anton 5-Nov-2008 [856] | I note in the "wireshark log.txt" you linked above, there is [TCP CHECKSUM INCORRECT] soon after the STOR command. I don't know what it means exactly. |
| Pekr 5-Nov-2008 [857] | FIN, ACK - your PC closes the connection (REBOL version) after receiving previous ACK, dunno why. Why is "spiral-admin" btw? |
| Dockimbel 5-Nov-2008 [858] | Your REBOL FTP session doesn't seem to use passive mode while Total Cmd does. |
| Pekr 5-Nov-2008 [859] | I think we several times suggested to set system/schemes/ftp/passive: true, and IIRC Vladimir claimed that it made no change for him .... |
| Vladimir 5-Nov-2008 [860x6] | I set it to passive |
same error.... here is the log | |

what is gtrack-ne ? | |
I tried again... now it is "ca-idms" instead of "gtrack-ne" and Seq=604 instead of 603.... I have no fu...ing... idea what this is... If there is anyone outthere who knows what this could be... ? | |
btw. I sent mails to pheenet (router manufacturer) support... Maybe they can help.... | |
| DideC 5-Nov-2008 [866] | I see no PORT command in Totalcommander log. That seems going in the way I claim before. |
| Graham 5-Nov-2008 [867] | What are these retransmission requests?? |
| Pekr 5-Nov-2008 [868] | Guys - those names, are just names for port numbers. You can turn the name resolution off. grack-ne = 3592 |
| Graham 5-Nov-2008 [869] | total commander is also using PASV mode |
| Pekr 5-Nov-2008 [870x2] | Spiral-admin = 3438 |
One thing is clear - you have to have allowed connection tracking in your firewall, and ftp communication is being done by using so called "related" connections ... | |
| Vladimir 5-Nov-2008 [872] | I uploaded manual for my router before: http://www.2shared.com/file/4192455/b9f6ca7d/LB_Manual_1_1.html Can someone tell me where are these settings for "connection tracking" ? |
| Anton 5-Nov-2008 [873x3] | About TCP CHECKSUM INCORRECT |
http://wiki.wireshark.org/TCP_Checksum_Verification | |
It should be VERY VERY rare to see corrupted packets in today's networks unless you have a router or a switch with a bad RAM module with a sticky bit. Still, it should be VERY rare to see this for packets that actually are corrupted. | |
| Vladimir 15-Nov-2008 [876] | I got response from Pheenet tech support... It tokk couple of emails ... me sending network drawing, log files and such stuff... Finally they said they never expirienced anything like it in their practice... Well at least I know Im not idiot... :) Only latest firmware could help... They were very kind and sent me newest firmware... (its not even available online :) AND IT WORKS! So.... Rebol is still cool... It was not rebol mistake... it was router firmware... :) Thanks to everyone who tried to help :) |
