Follow instructions in the UPGRADING file. If you're upgrading more than one version up, it is recommended that you upgrade one version at a time, log in to the site and globally change one of your users' attributes to make glftpd re-write all userfiles (and do some conversions if necessary). For example, log in as siteop and do "site change * max_ulspeed 0" after each version upgrade. Back to Contents
Log off and back on. Glftpd reads its config file each time a user logs on. If someone tells you to HUP inetd, tell him he's an idiot and doesn't understand how glftpd works. HUPping inetd is needed after making changes to inetd.conf, not glftpd.conf. Back to Contents
To turn it off for all existing users and any future users, type this at the shell: ls /glftpd/ftp-data/users |while read usr; do echo "IP *@*" >>$usr; done Change the path if you installed glftpd elsewhere. Back to Contents
For symlinks to work right, the target of the symlink must be in the glftpd
root path. It is best to just mount the partition under /glftpd/site.
A symlink from /glftpd/site to /glftpd/bleh will have to be without the
rootpath, so it will go from /site to /bleh. The above will only work if
users' homedir is set to /. Users can't access anything outside of their
homedir, so if it is /site, they won't be able to jump to /glftpd/bleh.
Your links need to start with . and they can't have the rootpath or homedir
in them. Examples:
ln -s ./incoming/mydir mydirshortcut
ln -s ../archive/games games
The reason for this limitation is for security purposes. When a user logs
in, he is "chrooted" to /glftpd (or whatever the rootpath is), so it is
physically impossible to access anything outside. This prohibits any user
logged in from browsing outside the glftpd root directory. If you're
familiar w/ wu-ftpd and telnet, normal users are permitted to browse
anywhere permissions permit. This is not a desired feature for this server,
and we feel the "cost" is worth the security.
You can also use the mount -bind command but this is for use with the
latest and latest mount version on linux. This lets you mount a drive to
more than one mountpoint.

Create the account w/ the password you desire, and set IP0 to *@* (site addip <user> <pass> *@*). If you want to use an email for password, or any password, see glftpd.docs for syntax on the site chpass command. You also need to set the number of simultaneous logins to what you need it to be. (site CHANGE <user> NUM_LOGINS 0) 0=infinite (Update) In 1.15.6+ there is a new flag (8)..which is for anon users. e.g.: site adduser mp3 mp3 *@* site chpass mp3 * for any password site chpass mp3 @ for email-style passwords Then edit the ratio and credits...when the mp3 user logs in, the mp3 account is read in as a template...so each mp3 user that logs in will have a fresh ratio and credits.

When the user(s) uploads a file and a person with the nuke flag sees reason for it to not be on the site, they can NUKE it. This typically renames the directory. The rename format is definable in the config file. Nuking is designed to take away the credits and transfer statistics for the files from people that uploaded them. Back to Contents

Nowhere, it is not released for several reasons. 1. Evil hackers could find exploits easier and not report them. 2. Wanna-be 'coders' would start many variants of glftpd that they would claim are their own and they probably wouldn't share any work they do. There are several people with access to the source code; when we are confident that #1 is not a big issue and when we no longer care about #2, we will release the source code. Back to Contents

The standard ftp client under linux needs the line "ftp 21/tcp" in the /etc/services file. Other clients should work fine. If you need the standard ftp client to work, just keep your old "ftp 21" line in addition to the "glftpd 21/tcp" line in the services file. Back to Contents
When you change the max_users you need to kill off all glftpd sessions and stop running gl_spy. To solve this, type: ipcs ------ Shared Memory Segments -------- key shmid owner perms bytes nattch status 0x00000000 0 nobody 600 46084 11 dest 0x0000dead 2945 root 644 15840 0 locked ------ Semaphore Arrays -------- key semid owner perms nsems status ------ Message Queues -------- key msqid owner perms used-bytes messages 0x00000000 0 root 700 0 For linux type: ipcrm shm shmid (In this example, shmid is 2945) For FBSD type: ipcrm -m shmid b) Make sure your kernel isn't screwing with shared memory.

You can't, currently glftpd only support 1:x ratio. Back to Contents
You need to copy the head/foot/body files to SECTIONNAMEfile.head, etc. For example, if you add a section called ISO, you need to do this: cp alup.head ISOalup.head; cp alup.body ISOalup.body, etc, for every stats file in the text dir. Back to Contents

Change your dirlog entry in config file to have a / at the end of the path. For example: dirlog /site/incoming/*/ * The above will log /site/incoming/Newdir but not /site/incoming/Newdir/dir1 Back to Contents
Yes, but: 1) The user must have resume permissions for that file (set in glftpd.conf) 2) The uploader must be the file's owner 3) The file's permissions need to be 644 (default in glftpd) Keep in mind that you might need to disable post_check (zipscript) in the directory where you want resume to work - o modify it not to delete incomplete files.

1) You aren't running glftpd as root (the default line for inetd.conf runs it as root, so you must have changed it) 2) Your rootpath is incorrect in glftpd.conf. Back to Contents

1) Ban it in your firewall. 2) If you're using tcpd in inetd.conf to call glftpd (this is default), ban the IP in /etc/hosts.allow. Exmp: glftpd: ALL except 1.2.3.4 For more info, try "man tcpd" or "man 5 hosts_access" on slackware 3) To ban that IP for only specific user(s), add it to a file, with a ! in front, and add that file as IP0 of that user. See addip syntax in docs. Back to Contents
1) Add *@* to the user you're trying to connect as (yes, if your IP is not added to any users, you won't even get a login prompt). 2) Add "glftpd: ALL" to /etc/hosts.allow (unless you didn't use tcpd in inetd.conf) 3) Make sure you're not using a firewall of some kind. 4) If you're using "valid_ip" in config file, comment it out and try again. 5) Check glftpd logs and system logs (make sure your system logs errors) Back to Contents
Are you modifying the correct config file? By default it's /etc/glftpd.conf, not /glftpd/etc/glftpd.conf or /glftpd/glftpd.conf. Back to Contents
Edit /glftpd/etc/passwd and change last user's UID to 10000. Back to Contents
Yes. Add these lines to your config file: privpath /site/hiddendir/yourdir * privpath /site/hiddendir =NoOne (make sure you don't have a group called NoOne) Then go to /glftpd/site and make a symlink, ie. ln -s ./hiddendir/yourdir link_to_yourdir Note: once you cd to link_to_yourdir, you can't do "cd .." because ".." is protected. To get out, either "cd /" or make a symlink in yourdir that points to "../.." . Also, some clients will automatically cd to the proper parent when you are in a symlink-directory, but only if they know it's a symlink. If you use ls -L (or if your lslong setting in config file has the L in its options), the symlink appears as normal directory so the client thinks it's just a regular directory. Back to Contents
Yes. Here is what you need to add to restrict "site laston" to siteops only, without affecting other commands controlled by "-info", to glftpd.conf: site_cmd laston is laston custom-laston 1 Back to Contents
Are you missing the HOMEDIR line from your default.user file? Don't edit default.* files with useredit. Back to Contents

Glftpd uses GID to store the number of times a file was downloaded (it stops counting at 99). So, if a file's GID is 428, it means the real GID is 400 and the file was downloaded 28 times. This will increase each time the file was downloaded until it reaches 499. The number of times the file was downloaded is displayed in long directory listing (ls -l) if you have color turned on (so as not to interfere with windows clients, which require color to be off). Back to Contents
No, but there is a work-around. For example, to allow everyone to execute stat commands (wkup, daydn, etc) but only allow siteops to execute site traffic, do this: 1. Add a custom command traffic: "site_cmd traffic is traffic" 2. Add permissions for your new command: "custom-traffic 1" (this will only allow siteops to execute site traffic) 3. Your -stats permissions should be "*" to allow everyone to use them. If you do it the other way around, giving "site traffic" * access and "-stats 1", it will not work because site traffic now uses 2 sets of permissions, one with the custom-traffic setting, and the other one with the -stats setting; user has to pass both to be able to execute the command. Back to Contents
No, you need inetd, xinetd, or some other program that works in a similar fashion. You need to run glftpd as root, anyway, so why not use inetd? Back to Contents
No. Glftpd needs a userfile for each user; normal unix users don't have any such thing, so you would have to generate a userfile for every person even if glftpd supported it. It's just as easy to write a script that will add the user to glftpd (by either modifying /glftpd/etc/passwd and creating the userfile in ftp-data/users, or logging into glftpd and using site commands). Back to Contents
Shadow is simply the same thing as passwd but only readable by root. Glftpd's passwd file can be made 600 already, so you could say glftpd always supported it. For more info see the question above. Back to Contents
