Hi, No sure what I have done (same old story), but for some reason, connecting to/via certain services on my server box (SuSE 6.4) now takes up to a minute, but other 'services' are instant. Everything was 'instant' before. For example... connecting to Samba = Instant connecting via SSH (port 22) = 1 Minute connecting to Interbase (port 3050) = Instant connecting to CVS (port 2401) = 1 Minute connecting to Borland AppServer = Instant The only 'major' thing I have done recently is set up my box to be a dial in PPP server. Any ideas? Cheers Phil

is ident working? i just found out yesterday that even qmail sends ident requests to clients. so i could very well imagine that the two unix services ssh and cvs above use ident as well while samba (aick!), interbase, and borland don't. use nmap or telnet to check the status of tcp port 113 on all involved boxes. martin [greetings from the heart of the sun]# echo madduck@!#:1:s@\@@@.net -- "Even if you persuade me, you won't persuade me." -- aristophanes
I've got the ident port blocked at packet filtering level, but have no
delays with ssh. The packet filter does not appear to be seeing any
requests to it, either, so I doubt if ssh is necessarily trying ident. I
don't know if the other services you mention need to.
Sorry this isn't an answer to your problem, but maybe helps with elimination
of possibles?
Best
Fergus

Hi,

use nmap or telnet to check the status of tcp port 113 on all involved boxes.
Using nmap, ident does not show up. What I did notice was that the 'ports' that connect instantly were not listed, but those that take a minute or so to connect are. Cheers Phil

Only suggestion would be to check that you can reverse lookup your IP address correctly. This can cause problems sometimes, especially with ssh. Bye, Chris -- __ _ -o)/ / (_)__ __ ____ __ Chris Reeves /\\ /__/ / _ \/ // /\ \/ / ICQ# 22219005 _\_v __/_/_//_/\_,_/ /_/\_\

This could be the cause, as I was having problems with IP look up when setting up PPP. As I a complete idiot, how do I check that I can reverse lookup my IP? Cheers Phil

Hi,
nslookup xxx.xxx.xxx.xxx
Bingo. Thats the problem I think, I get... *** Can't find server name for address xxx.xxx.xxx.xxx: No response from server *** Default servers are not available .... Now, how to fix it? Cheers Phil

You have a couple of options here. The best (and easiest) option is to set up a DNS server on your network (if you haven't already done so) and persuade all your boxen to use your DNS server to look up names. It really isn't all that difficult - just read the DNS-Howto. Install the RPM, enable named in /etc/rc.config, add a zone for your local lan into /etc/named.conf and then create a couple of zone files for the forward and reverse zones. It's as simple as that ;-) Give me a shout if you need a hand, Chris -- __ _ -o)/ / (_)__ __ ____ __ Chris Reeves /\\ /__/ / _ \/ // /\ \/ / ICQ# 22219005 _\_v __/_/_//_/\_,_/ /_/\_\
