TCP wrappers is a simple tool to block incoming connection on application level. This was very useful 20 years ago, when there were no firewalls in Linux. This is not the case for today and connection filtering should be done in network level or completely in application scope if it makes sense. After recent discussions I believe it is time to go for this package, if not completely, than at least as a dependency of modern daemons in system by default.

By default by si malo AP stiahnut aktualny ios z controllera. V mojom pripade som vsak potreboval pripojit starsi kusok a na controllery nebol ios k dispozicii. Preto bolo potrebne manualne upgradenut ios na apcku.
Ako prve sa pripojim k AP cez konzolu.
AP70e4.22cf.124c#
A uvidim nasledovne hlasky, ze nie je mozne stiahnut ios z controllera
*Feb 19 11:04:17.447: %CAPWAP-6-AP_IMG_DWNLD: Required image not found on AP. Downloading image from Controller . *Feb 19 11:04:17.451: Loading file /ap1g3...
V tomto pripade je potrebne srpravit manualny upgrade. Pripravim si oblubeny tftp server s ios imageom.
AP70e4.22cf.124c# debug capwap console cli
A skuim nahrat software z tftp servera
AP70e4.22cf.124c# archive download-sw tftp://10.10.180.48/ap1g3-k9w8-tar.153-3.JF10.tar
Moze sa stat ze dostanem nasledovny error
Unable to create temp dir "flash:/update"
Vtedy je potrebne zmazat dany adresar z flashky
AP70e4.22cf.124c# delete /f /r flash:update
A skusit znova
AP70e4.22cf.124c# archive download-sw tftp://10.10.180.48/ap1g3-k9w8-tar.153-3.JF10.tar

Vidime ze v tomto pripade uz doslo k uspesnemu nahratiu sw na AP. Po skonceni dame reload a zariadenie bude uspesne upgradnute. Ak nechceme
drzat stary ios mozeme pouzit pri nahravani sw pouzit prepinac /overwrite
