Default iTCL morons.. read this

Fancy topic ehh... now have this: :banana: before you'll start drooling...

I'm devoting next version for itcl updates. List of planned updates is below. If you have any suggestions, speak now or wait for ever.

userfile
isopen : Returns id of open userfile, -1 on error
open : Opens userfile
reload : Reloads userfile
lock : Locks userfile
unlock : Unlocks userfile
bin2ascii : Converts userfile to ascii
ascii2bin : Converts ascii to userfile (userfile must be locked at this point)
swapactive : Swaps open userfile with current user's active userfile (if any)

groupfile
isopen : Returns id of open groupfile, -1 on error
open : Opens groupfile
reload : Reloads groupfile
lock : Locks groupfile
unlock : Unlocks groupfile
bin2ascii : Converts groupfile to ascii (groupfile must be locked at this point)
ascii2bin : Converts ascii to groupfile

mountfile
load : Loads mountfile (vfs file)

I removed the swapactive.. as it's too easy to exploit (if you manage to create exploitable script [= do not use proper parameter checking])


iputs "Opening userfile"
if { [userfile open "darkone"] == 0 } {
iputs "Open!"
iputs [userfile bin2ascii]
}

ascii2bin converts file from bin2ascii form to binary userfile structure. (updates userfile in ioftpd) In another words:

userfile open "darkone"
userfile lock
set foo [userfile bin2ascii]
# do something with $foo
ascii2bin "$foo"
userfile unlock

updates userfile for darkone it can't get much easier than that

Hello dark,

It would be cool if you add some commands to check activity per services/users/groups

examples :

activity <service> :

--> [activity "FTP_Service"] return :

"uid" "gid" "pwd" "ident@ip" "path" "flags" "speed" "idletime" "action (DL/UL/IDLE)"

activity <-user> :

--> [activity "-ViNcE"] return :

"uid" "gid" "pwd" "ident@ip" "path" "flags" "speed" "idletime" "action (DL/UL/IDLE)"

activity <=group> :

--> [activity "=STAFF"] return :

"uid" "gid" "pwd" "ident@ip" "path" "flags" "speed" "idletime (in seconds)" "action (DL/UL/IDLE)"

(don't forget the quotes so we can get info easily)

and return -1 on error if service/user/group doesn't exists or something else...

We can maybe be able to use that too :

activity <-user1 -user2 -user3 ...>
activity <=group1 =group2 =group3 ...>

That's all for me maybe a lot for you, but if u want to make a version especially for itcl scripters, make it complete and well :P

Have fun!

I don't see reason why ioFTPD should do the parsing; I could give you access to list of users online, but that will not have that kind of options => you will get global list, which you may, or may not parse yourself.

Usage could be something like this:

set fh [client who init]

if { $fh != 0 } {
while {[client who fetch $fh] == 0} {
set path [client who virtualpath $virtualpath]
set datapath [client who virtualdatapath $fh]
set status [client who status $fh]
set service [client who service $fh]
set uid [client who uid $fh]
}
client who close $fh
}

Or:

set fh [client who init "path" "virtualpath" "status" "service" "uid"]
if {$fh != 0} {
set loop 1
while { $loop } {
set data [client who fetch $fh]
if { "$data" != "0" }
{
# data is in following format:
#
# path<newline>virtualpath<newline>status<newline>se rvice<newline>
#
# if I have time to study how-to give data back as arrays, you could use lindex to extract data
} else {
set loop 0
}
}
}

I decided to use the second implementation as it's easier to parse & has less overhead (only data you request, is being copied)

if { [client who init "UID" "VIRTUALPATH"] == 0 } {
while { 1 } {
set data [client who fetch]
if { "$data" == "" } {
break
}
iputs "Uid: [lindex $data 0] Path: [lindex $data 1]"
}
}


SITE KILL is something simple as:

set uid [resolve user $args]
if { $uid == -1 } {
iputs "Could not locate user"
return 0
}
# We should check for master flag!
if { [client who init "UID" "CID"] == 0 } {
while { 1 } {
set data [client who fetch]
if { "$data" == "" } {
break
}
if {[lindex $data 0] == $uid]} {
client kill clientid [lindex $data 1]
iptus "Gave death signal to client [lindex $data 1]"
}
iputs "Uid: [lindex $data 0] Path: [lindex $data 1]"
}
}

Some more cool things added (timers & command to load new mountfile)

## Resolve paths
set pwd "/mnt/d-drive"
iputs "Resolved $pwd to [resolve pwd $pwd]"
if { [mountfile open "d:/ioFTPD/etc/default.vfs"] == 0 } {
iputs "Mountfile read!"
iputs "Resolved $pwd to [resolve pwd $pwd]"
}

## Create timer, interval 5000ms/5s
if { [timer 5000 "TCL ../scripts/tcltimer.itcl $uid"] == 0 } {
iputs "Timer created! It kills user with uid $uid in 5seconds..."
}

here's the full script that I used to test functions:

#iputs "$args"

iputs "Opening userfile"

if { [userfile open "darkone"] == 0 } {
iputs "Open!"
iputs [userfile bin2ascii]
}

## Fetch who list
if { [client who init "UID" "VIRTUALPATH" "CID" "TRANSFERSIZE"] == 0 } {
while { 1 } {
set data [client who fetch]
if { "$data" == "" } {
break
}
iputs -nobuffer "Uid: [lindex $data 0] Path: [lindex $data 1] Transfered: [lindex $data 3]"
}
}

## Resolve paths
set pwd "/mnt/d-drive"
iputs "Resolved $pwd to [resolve pwd $pwd]"
if { [mountfile open "d:/ioFTPD/etc/default.vfs"] == 0 } {
iputs "Mountfile read!"
iputs "Resolved $pwd to [resolve pwd $pwd]"
}

## Create user, rename it & finally delete (same commands apply to groups)
set name "lamer"
set newuid [user create "$name"]
if { $newuid >= 0 } {
iputs "Created user $name"
if { [user rename "$name" "$name\_delete"] == 0 } {
iputs "Successfully renamed user $name to $name\_delete"
set name "$name\_delete"
} else {
iputs "Failed to rename $name to $name\_delete"
}
if { [user delete "$name"] == 0 } {
iputs "User $name is history!"
} else {
iputs "Could not delete user $name..."
}
}

## Show hashed string
iputs "Hash for \"dungeon\": [sha1 "dungeon"]"

## Create timer, interval 5000ms/5s
if { [timer 5000 "TCL ../scripts/tcltimer.itcl $uid"] == 0 } {
iputs "Timer created! It kills user with uid $uid in 5seconds..."
}

#client kill clientid [lindex $data 2]

set ioerror 0

Experiment.. it retusn 0,1,2,3

0 = no transfer?
1 = upload?
2 = download?
3 = list?

could be wrong
