Hi: I have a freebsd-4.8-release box that recently crashed due to hardware [fan] failures after being up for 18 months. It runs the stock ftpd server out of inetd. - It does *not* use ftpchroot - It is *not* setup as an anonymous ftp server When the system came back up, remote connections to the ftp server result in: $ ftp nnn.nnn.nnn.nnn 421 Service not available, Remote server has closed the connection Connections from the box to itself work fine: $ ftp localhost Connected to localhost.esca.com. 220 somehost.some.domain FTP server (Version xxx) ready. Here are the troubleshooting steps I have followed thus far [it is in a location with no remote access, so I'm talking a technician through this]: - Verified default inetd entry invokes '/usr/libexec/ftpd -l' [since it works locally this should be OK] - Disabled ipfilter firewall - Verified that default /etc/hosts.allow contained 'ALL : ALL : allow' as the initial line [also edited the file to contain only this line, to no effect] - Verified that /etc/hosts contains correct address/hostname entry for the system, matching corresponding into in /etc/rc.conf. The box does *not* use DNS [lookups disabled]. So I'm wondering what types of things would cause remote connections to give a 421. Googling and looking at the archives for this list point to ftpchroot problems as the typical issue. Not here. Thanks for any tips you can offer - Jeff ------------------------------------------------------------------------------------------ Jeff Stelzner ------------------------------------------------------------------------------------------ "spukhafte Fernwirkungen" --------------------------------------------------------------------------------------------
