Re: IPTables outbound problem

Whatever the problem is, it's unlikely to be your iptables. You have a default policy of ACCEPT on the OUTPUT chain and your only rule there jumps to the PETER chain which contains only one rule that allows outbound connections to ports 25025-25050 on the remote server. If it matches that rule then ...

Re: mellanox mhqh29b-xtr dual ethernet adapter install

Try running modprobe mlx4_core and then look in /var/log/messages and/or dmesg to see what that says. If lsmod reports it already loaded then modprobe -r it and then modprobe it so you see the current set of messages in the logs.

Re: Kernel compilation on CentOS

We don't support or recommend use of mainline kernels at all. We recommend use of the kernels we ship - which are the same ones in use by RHEL minus the RH branding.

Re: mellanox mhqh29b-xtr dual ethernet adapter install

grep -i 15b3 /lib/modules/3.10.0-693.2.2.el7.x86_64/modules.* | grep -i 673c says that's supported by the mlx4_core module in the current CentOS 7 kernel.

Re: mellanox mhqh29b-xtr dual ethernet adapter install

Now try that again with lspci -nn so we can see the vendor/device ids.

Re: mellanox mhqh29b-xtr dual ethernet adapter install

yes i know but i do not understand why servers do not see the cards inserted.


That would be a hardware problem to be solved. You won't get linux to use the cards until they show up in lspci - that has nothing to do with any driver.

Re: Cisco VPN on CentOS

You could try using the opensource 'vpnc' package from EPEL instead. There's also NetworkManager-vpnc.x86_64 and NetworkManager-vpnc-gnome.x86_64

Re: mellanox mhqh29b-xtr dual ethernet adapter install

Those don't look like Mellanox adapters, they look like the on-board quad port HP/Broadcom 1Gbe adapters. Is there anything in the output from lspci -nn that mentions Mellanox at all? If not then the card isn't even plugged in right.
