I am using a very small adhoc ftp server (ftpdmin) on my laptop. However I get strange error that I am not able to find resolution. The Root Directory for FTP has read / write permissions to everyone.Here is some capture of the ftp logs as well as router / switch command that I am trying to test:Switch#copy run ftp://10.10.10.1Address or name of remote host [10.10.10.1]? Destination filename [switch-confg]? Writing switch-confg %Error writing ftp://10.10.10.1/switch-confg (Undefined error)And on Laptop:C:\>ftpdmin C:/TFTP-Rootftpdmin v. 0.96 Jun 7 2004Using 'C:\TFTP-Root' as root directoryftpdmin ready to accept connections on ftp://10.10.10.1 220 Minftpd readyUSER anonymous 331 pretend login acceptedPASS router@cisco.co 230 fake user logged inTYPE I 200 Type set to IPORT 10,10,10,6,42,253 200 PORT command successfulSTOR switch-confg 150 Opening BINARY mode data connectionconnect() failed: No error 550 No errorWhat could be wrong? There is no firewall or anything else that is blocking. I have tested both ftp passive and active on router.Please advise as I am planning to do IOS upgrades on 2811and 1841 routers on a VPN network remotely from HQ and want to make sure that the large images get transfered soonest possible (I have to delete existing images to be able to accomodate the new image, and in absence of any image on flash, I want to make sure that new image is transfered soonest via FTP rather than using TFTP byte by byte and wait and acknowledgement protocol. I am also not sure if tftpd32 or any other tftp server and cisco routers themselves will permit larger than 32MB images to be transfered over tftp.Much thanks. 3186Views Tags: none (add) Reply (Login Required) 1. Re: FTP client on Router dpsharma Oct 8, 2009 6:11 AM (in response to dpsharma) Good Morning Folks, Can someone look into this and advise? The adhoc ftp server that I am using works fine when I use any ftp client ( including browser) on any PC on the LAN.Any help will be greatly appreciated. Like Show 0 Likes (0) Reply (Lo

There is a size limitation of 16MB on (most) tftp servers. 3Com's http://www.tek-tips.com/viewthread.cfm?qid=574147 tftp daemon is supposed to work with IOS's bigger than 16 meg. Trouble is I only have a 1750 to play with, so I cannot use real IOS file that are big enough to test it.However FTP is also available, and I am trying to move the 1750 IOS about using this.I have managed to copy an IOS to a PC using anonymous FTP with Meteor FTP server. However trying to copy to the router fails witha protocol error.I have also tried WAR FTP, and the FTP element of 3Coms combined tftp/FTP server, but these both fail to handle the anonymous login for copy to or from the server.If anyone can confirm the 3Com tftp daemon does the job properly then I will go with that.ThanksEB RE: FTP IOS transfers routerman (TechnicalUser) 12 Jun 03 05:35 I've used this, when you set up the FTP user name and password on the router I found that you need to also issue `no ip ftp passive'command. The router defaults to passive FTP and my server didnt support that option.Before discovering this the router logged into my FTP server OK but then came up with a protocol error.

Andy Leates MCSE CCNA MCP+I RE: Copy FTP flash comand fails on 3725 and 3745 routerman (TechnicalUser) (OP) 3 Oct 03 10:52 No, I mean copy FTP flash, its a far quicker way of transferring IOS images onto a router. I'm not sure when support for this feature was introduced, but it sure beats waiting around for a TFTP upload.Try enter the command on one of your routers.I've now had 3 3725 routers and last night I tried this on a 3745, the FTP transfer starts but then I get a protocol error.

Post #1 of 6 (2835 views) Permalink IOS install issues After the issues I had with the VICs not being recognized, I figured I would start with a newer IOS to see that that would help. However when I try to copy tftp flash: I get the following error: %Error opening tftp://192.168.1.1/c1700-sv3y-mz.123-19.bin (Socket error) The only document I found stated that this can be an issue if the router is set to boot from tftp but that is not this case, but I tried the suggestion anyway. I have rebooted the router, and the laptop running the tftp server (Solarwinds) I have made sure it was listening on port 69 I can ping back and forth There do not appear to be any Ethernet errors. Any ideas?

Two suggestions: First, check to make sure you've got the Windows firewall turned off (or anything else like that). Second, if the router has multiple IP addresses the TFTP request might be coming from an address that isn't reachable on the PC. Unlikely, but possible. I don't use Solarwinds but the Pumpkin TFTP server will tell you what IP address is doing the request. You might try entering "ip tftp source-interface
