Dr Web Update Timing Out

[Shawn M]

Any clue about this?

ERROR: Dr.Web (R) Updater: Unable to connect to update.msk5.drweb.com: Connection timed out !

First of all check that hostname update.msk5.drweb.com is accessible and resolvable from your server.

Hi,

I didn't have any problems before.

How would I check to see if it were resolvable?

 

[IgorG]

For example:

$ host update.msk5.drweb.com
update.msk5.drweb.com has address 87.242.75.74
update.msk5.drweb.com has address 83.222.3.90

$ ping update.msk5.drweb.com
PING update.msk5.drweb.com (83.222.3.90) 56(84) bytes of data.

64 bytes from 83.222.3.90: icmp_seq=2 ttl=50 time=125 ms

$ telnet update.msk5.drweb.com 80

Hi,

It connected fine.

 

[Shawn M]

I found that sometimes it connects and sometimes it does not. I've pinged and it timed out and I've pinged and it's worked fine. any ideas?

 

[IgorG]

Maybe there is problem with hostname resolution? Try to define more reliable nameservers in /etc/resolv.conf

 

[Shawn M]

The host names that are listed in that file, what exactly are those for?

 

[IgorG]

You can use any good nameservers there. For example:

$ cat /etc/resolv.conf
nameserver 4.2.2.1
nameserver 4.2.2.3
nameserver 66.7.207.2
nameserver 66.7.206.2


$ host 4.2.2.1
1.2.2.4.in-addr.arpa domain name pointer vnsc-pri.sys.gtei.net.

$ host 66.7.207.2
2.207.7.66.in-addr.arpa domain name pointer ns1.dimenoc.com.
