I'm trying to change the RX and TX for an HP BL460C server by using ethtool and get the following:

ethtool -G eth0 rx 4078 tx 4078
Cannot set device ring parameters: Operation not supported

My driver information is as follows:

The adjustments are needed for a multicast application we are running on this server.

[root@newserver Socket]# /root/scripts/filetest testfile.txt
Can't locate loadable object for module IO::Socket::Multicast in @INC (@INC

/usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5

filetest is calling "use IO::Socket::Multicast;"

The contents of the directory /usr/local/lib64/perl5/IO/Socket is the following:

-rw-r--r--. 1 root root  3111 Mar 22  2017 UNIX.pm

Why can't perl find the Multicast.pm?

We are experiencing an odd situation, our DNS/domain controllers keep losing there ability to connect to the root hint servers. This lasts for about 5 minutes and happens a few time everyday.

We have hopped on the DNS server while this is happening and have opened a command prompt and were able to successfully ping the root hint servers manually from the DNS servers so we know if is not a internet connectivity issue.

We ran a dcdiag during the event and saw that the DNS servers were able to connect to each other but they could not connect to the root hint servers.

When this is happening we lose the ability to resolve FQDNs

All help would be appreciated.

I am writing a script that copies files to another directory. I wanted to append the date to the end of the file but when I try to use %date% I get the following:

copy c:\mydir\file.zip "c:\temp\file-%date%.zip"

The system cannot find the path specified.

     0 file(s) copied.

if I remove the %date% it copies just fine

Thanks

I have the following rsync exclude that I am trying to run:

rsync -av --exclude 'home/dir/public_html/config.text' root@remote.
server.com:/home/dir/public_html/ /home/dir/public_html

I have searched documentation and I believe I am doing it right, but I am obviously doing something wrong.

I have mediawiki on an internal server for one of my groups and it is running fine. I wanted to setup another wiki for a different internal group and I followed the instruction on how to do so on the following link http://sharkysoft.com/wiki/how_to_configure_multiple_MediaWiki_instances_on_a_single_host. The original install is on 192.168.10.25/mediawiki I am trying to add 192.168.10.25/mediawiki/itwiki, but when I point to that url I get redirected to 192.168.10.25/mediawiki.

I have the following slow query information setup in mysql.

SHOW VARIABLES LIKE '%SLOW%';

Variable_name     Value 
log_slow_queries  ON 
slow_launch_time  2
slow_query_log    ON 
slow_query_log_file   /var/log/mysql/slow-queries.log

The log file has the following premissions:

-rwxr-xr-x 1 root root 0 Sep 11 14:31 slow-queries.log

The my.cnf file looks like this:

back_log = 2000
slow_query_log = 1
slow_query_log_file = 1
long_query_time = 1 
general_log = 1
log-slow-queries=/var/log/mysql/slow-queries.log

From mytop I can see that I have slow queries, but I don't see anything writing to the logs.

I am trying to figure out where my tcp resets on my webserver happen. I have the following capture:

tcpdump -fnni bond0:-nnvvS -w dump.pcap 'tcp[tcpflags] & (tcp-rst) !=0'

When I look at the pcap in wireshark shows me resets:

    Flags: 0x004 (RST)
    .... .... .1.. = Reset: Set
    .... .... ..0. = Syn: Not set
    .... .... ...0 = Fin: Not set

Window size value: 0
Calculated window size: 0
Window size scaling factor: -1 (unknown)
Checksum: 0x0f2f [validation disabled]
Good Checksum: False
Bad Checksum: False

but doesn't show me who reset the connection. I believe that there are switches in tcpdump that would allow me to see who reset the connection and possibly why. I have tried various switches with no luck.

Thanks in advance for your help.

I am trying to move a snapshot from an esxi 5.0 vm to another datastore, but when I tried to use the datastore tools I got the following error, "error caused by file" with a path to the vdmk file. So I am to use vmkfstools to move the snapshot but can't find how to move the snapsot. I found how to migrate a virtualdisk:

vmkfstools --server 10.21.49.14 -i '[Datastore] examplevm/examplevm.vmdk' '[Datastore 2] newexamplevm/newexamplevm.vmdk' -d thin

I have searched other forums and but haven't found any examples. I am not sure that the above command would move the snapshot. Has anyone used vmkfstools to move a snapshot? If so please provide an example

I have two nics bonded in gentoo, eth2 and eth3 to bond0. eth2 is connected to a different switches than eth3 for redundancy with eth2 in standby and eth3 in active mode. eth3 is running fine with no drops but eth2 is dropping packets constantly.I swapped cables and checked the switch ports which show no errors. I did a TCPDUMP on eth2 and all I saw was arp requests.

• I believe the problem is most likely caused by the broadcast arp requests coming from eth2 (standby) slave in the bond. Does anyone know how to turn off broadcast arp on a slave bond?

**

I have rules like this in my IPTABLES:

-A INPUT -s 166.100.102.50/32 -j LOG --log-level 7

and I wrote a script that grabs the output of these rules and outputs the bytes from the IP to my server.

I was hoping to get suggestions on how I could create a rules that tracks ip traffic from dispersant subnets. The ip address aren't fixed and even the subnets aren't fixed. For example:

120.2.33.45 could be the ip address of the device one day and 204.65.3.88 could be the ip address of the same device the next day.

I think that if there was a way to write the rule so that it gave me the ip address of everything except a range of ip address that are fixed, like 166.100.102.50 then I would be ok.

Something like:

-A INPUT -s NOT EQUAL 166.100.102.50/32 -j LOG --log-level 7

Thanks in advance

I have one an issue that I would be extremely grateful for help with. When I check the AP join statistics I see the following:

Reason For Last Unsuccessful Attempt RADIUS authorization is pending for the AP

I don't run a radius server and don't know how to get around this so that the device can join.

Thanks in advance for your help!!

I have a 1142 that I purchased that needs to be set to factory defaults so that I can configure it. I do an escape at the boot sequence and I get to the

ap:

prompt, the reset instructions that Cisco provides says that I should rename the old config.txt and reboot and that I will then be able to start my reconfig. The problem is that I can't find a config.txt file in the flash space:

Directory of flash:/

I checked in the directories listed above and still found no config.txt. I appreciate all help since I am stuck and can go no further.

Thanks,

I have the following script:

cd "/usr/local/bin/"     
/sbin/startproc ./program1

I have a license in the /usr/local/bin directory and if the program isn't started from there it won't launch correctly.

The cd "/usr/local/bin" doesn't seem to be doing the trick.

I have the following configuration in my iptables and syslog files:

IPTABLES

-A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT

-A INPUT -p tcp -m tcp --dport 80 -j ACCEPT
-A INPUT -p tcp -m tcp --dport 222 -j ACCEPT

-A INPUT -p tcp -m tcp --dport 3306 -j ACCEPT

-A INPUT -j DROP

-A INPUT -m limit --limit 5/min -j LOG --log-prefix "iptables denied: " --log-level 7

SYSLOG-NG

destination d_iptables { file("/var/log/iptables/iptables.log"); };

filter f_iptables { facility(kern) and match("IN=" value("MESSAGE")) and match("OUT=" value("MESSAGE")); };

filter f_messages { level(info,notice,warn) and
                    not facility(auth,authpriv,cron,daemon,mail,news) and not 
filter(f_iptables); };

log { source(s_src); filter(f_iptables); destination(d_iptables); };`

I restart syslog-ng and the log is not written.

I have a cisco 4500 switch that has a direct connection to a dell 3516 blade switch. I am getting a large number of input errors. I have tried new cables and still continue to see the errors.
