- Using ProFTPD with Solaris 2.5.1 (possibly even other versions):
- [Ed: Note, in Solaris 2.6 this is no longer necessary]
- Solaris 2.5.1 has an odd problem involving tcp sockets inside of a
- chroot() [as used w/ DefaultRoot and Anonymous logins]. Apparently, due
- to the Solaris xti code, socket operations initially attempt to open a few
- devices, including /dev/tcp, /dev/udp, /dev/zero and /dev/ticotsord. This
- is most likely caused by the networking libraries, and is completely out
- of the control and/or scope of ProFTPD.
- Solaris 2.5.1 users wishing to use ProFTP will have to do something like
- the following in their anonymous or otherwise chroot'ed directories:
- [ !!NOTE!! Do not use the major/minor device numbers below verbatim.
- Solaris on different archs will use different major/minors. Check
- your OS documentation first before doing this. ]
- mkdir dev
- mknod dev/tcp c 11 42
- mknod dev/udp c 11 41
- mknod dev/zero c 13 12
- mknod dev/ticotsord c 105 1
- Solaris 2.5 (and possibly 2.5.1) requires these additional device
- nodes to be created in order to avoid a system panic when the
- loopback interface is used:
- mknod dev/ticlts c 105 2
- mknod dev/ticots c 105 0
- # the following is necessary to allow proftpd to create a socket
- # when in non-low-port mode (such as during passive transfers)
- chmod 0666 dev/tcp
- Failure to create these files will result in "socket() failed in
- inet_create_connection(): No such file or directory" when a user logs in
- anonymously and attempts to transfer data of any type (including a simple
- directory listing).
- If you receive errors such as "socket() failed in
- inet_create_connection(): Permission denied", you need to chmod 0666 your
- dev/tcp device.
