That seemed to bethe case with Solaris 9 stuff.Anybody any ideas what i'm doing wrong? http://ibuildsystem.com/warning-cannot/warning-cannot-set-rr-scheduler.php Ipv6 is disabled by default on certain earlier Linux OS.

I've checked the man pages andthe only work around I have at the moment (which seems to be working) isto use inetadm to disable tcp_wrappers for the affected service.Thanks in advanceAde This is the safest and the best configuration. According to the error message, that's what it's looking up. http://ibuildsystem.com/warning-cannot/warning-cannot.php So that they can connect it.

UNIX & Linux Forums > Top Forums > UNIX for Advanced & Expert Users Member Name Remember Me? To the folks that wrote tcpd, I say I'm fine with the optimization, but please, for God's sakes *log the STINKING DOT* so we can tell what's going on.. TCP_WRAPPERS is controlled from two files and the search stops at the first match./etc/hosts.allow /etc/hosts.deny OpenSSH uses the same libwrap library, and this doesn't happen.
A discussion on the syslog levels which can be used is given in the SyslogLevel directive. UNKNOWN — Matches any host where the hostname or host address are unknown or where the user is unknown. Otherwise, access will be granted.Edit the hosts.deny file vi /etc/hosts.deny and add the following lines: Access is denied by default. # Deny access to http://ibuildsystem.com/warning-cannot/warning-cannot-load-sbd.php The mod_wrap module for ProFTPD does check for these values, thus why those connections are refused by mod_wrap but not OpenSSH.
KNOWN — Matches any host where the hostname and host address are known or where the user is known. My understanding was that thePARANOID setting in the TCP wrappers configuration files (hosts.allow)was what caused this to be checked. However, Outlook was the only reported affectedclient.......but then, it shouldn't make any difference because Iwouldn't expect the client to see anything different in this instance.Strange.Work around for now - disable tcp_wrappers I believe it's the x.x you have in there: in.ftpd: 191.95.x.x/255.255. 0.0 I changed it (a couple of times) and found this to work; in.ftpd: 191.95. /255.255. 0.0 in.ftpd: 191.95./255.255. 0.0
