I just installed Solaris 7 (intel), and I added the gcc, gzip and tcsh binary packages.  I changed the root's shell to /usr/local/tcsh from /usr/bin/sh and now, I can't FTP into my machine with root.  Either the password's changed or FTP as root's been disabled.  I can still telnet into the machine.  Any suggestions how to get the FTP access back?

I also get a

se: Command not found

when I telnet in..

Is there a place where I can go to get the tcsh source files other than www.sunfreeware.com?  I can't connect to that site right now since it's timing out..

Ignore the "se: Command not found" problem -- somehow the .cshrc file had "se" in it.. go figure..

First a word of caution. Changing root's shell is extremely dangerous unless you've taken the precaution of building a copy of the shell statically linked and place that copy in /sbin. If / /usr are separate and you have any significant problem with /usr so that it won't mount, you have no shell. Even if / & /usr are combined, any problem with shared libraries will leave you with no root shell. Either of these scenarios means that you have to boot off of the installation CD to fix the problem. We call this "The Dreaded Root Shell Disease"

Okay ftp stopped working because tcsh isn't one of the shells that in.ftpd knows about. Fix it by creating /etc/shells with at least the following in it:

/sbin/sh
/bin/sh
/bin/csh
/bin/ksh
/bin/tcsh

See the man ftpd & man shells for details.

Regarding building the copy of the shell in /sbin, I assume it won't be enough to copy the tcsh binary over there.. what would I have to do?

oh, I haven't had the chance to try the /etc/shells thing, but I'm pretty sure it'll work..

Right, more than likely just putting the tcsh binary in /sbin won't suffice. It's probably beeen built with shared libraraies, which you can check by "ldd /bin/tcsh". You'd have to get the tcsh sources and compile it youself, forcing static linking. Since I don't use tcsh, I can't tell you exactly what it would take to coerce the build process for tcsh to produce a static version. With bash, which I do use, it's a configure option (--enable-static-link).
